Accounting Policies [Abstract]
Mobile Mini, Inc. - Organization and Description of Business	(1) Mobile Mini, Inc. - Organization and Description of Business Mobile Mini, Inc., a Delaware corporation, is a leading provider of portable storage and specialty containment solutions. In these notes, the terms “Mobile Mini” the “Company,” “we,” “us,” and “our” refer to Mobile Mini, Inc. At March 31, 2016, we had a fleet of portable storage and office units operating throughout the U.S., Canada and the U.K. serving a diversified customer base, including large and small retailers, construction companies, medical centers, schools, utilities, distributors, the military, hotels, restaurants, entertainment complexes and households. These customers use our products for a wide variety of applications, including the storage of retail and manufacturing inventory, construction materials and equipment, documents and records and other goods. We also have a fleet of specialty containment products, concentrated in the U.S. Gulf Coast, including liquid and solid containment units, serving a specialty sector in the industry. Our specialty products are leased primarily to chemical, refinery, oil and natural gas drilling, mining and environmental service customers. On May 15, 2015, we closed a transaction to sell our wood mobile offices within our North American portable storage segment for a cash price of $92.0 million, less associated assumed liabilities. Activity directly associated with this business is included in the three months ended March 31, 2015, and is not included in the three months ended March 31, 2016. See additional information regarding the divestiture in Note 5 “Impairment and Divestiture of North American Wood Mobile Offices”. Basis of Presentation and Consolidation The consolidated financial statements include the accounts of Mobile Mini and our wholly owned subsidiaries. We do not have any subsidiaries in which we do not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management of Mobile Mini, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows for all periods presented have been made. The results of operations for the three months ended March 31, 2016 and 2015 are not necessarily indicative of the results to be expected for the full year. These condensed consolidated financial statements should be read in conjunction with our December 31, 2015 audited consolidated financial statements and accompanying notes thereto, which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 5, 2016. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and the notes to those statements. Actual results could differ from those estimates. Significant estimates affect the calculation of depreciation and amortization, the calculation of the allowance for doubtful accounts, the analysis of goodwill and long-lived assets for potential impairment and certain accrued liabilities. Reclassifications Certain amounts in the Condensed Consolidated Statements of Operations for the three months ended March 31, 2015 have been reclassified to conform to the current period presentation. The reclassifications have no effect on total revenues, loss from operations, net loss or net loss per common share. For the previously reported three-month period ended March 31, 2015, the reclassifications resulted in $2.1 million and $1.2 million increases to rental revenues and sales revenues, respectively, with an offsetting decrease to other revenue. For the same period, cost of sales increased $0.9 million, and rental, selling and general expenses decreased by the same amount. The revenues reclassified to rental revenues from other revenues consist of ancillary services such as equipment cleaning fees and equipment installation. The items reclassified from other revenues to sales include sales of certain ancillary products. Costs associated with these sales have also been reclassified to cost of sales from rental, selling and general expenses. We believe the current presentation better reflects the nature of the underlying financial statement items.

Accounting Changes And Error Corrections [Abstract]
Impact of Recently Issued Accounting Standards	(2) Impact of Recently Issued Accounting Standards Share-Based Compensation. In March 2016, the Financial Accounting Standards Board (“FASB”) issued a standard intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. This standard is effective for annual and interim periods beginning after December 15, 2016, and early adoption is permitted. We are currently evaluating the impact that the standard will have on our consolidated financial statements. Leases . In February 2016, FASB issued a standard on lease accounting requiring a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. This standard is effective for annual and interim periods beginning after December 15, 2018, and early adoption is permitted. We are currently evaluating the impact the standard will have on our consolidated financial statements. Simplifying the Presentation of Debt Issuance Costs . In April 2015, FASB issued accounting guidance on the presentation of debt issuance costs in the balance sheet. This standard requires that certain debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. We adopted this guidance during the current period. As a result, unamortized debt issuance costs of $2.3 million and $2.4 million as of March 31, 2016 and December 31, 2015, respectively, have been deducted from the carrying amount of our 7.875% senior notes due 2020 (the “Senior Notes”) in our balance sheet. Unamortized debt issuance costs related to our revolving lines of credit are included in other assets. Revenue from Contracts with Customers . In May 2014, FASB issued an accounting standard on revenue from contracts with customers. The standard provides a single model for revenue arising from contracts with customers and supersedes current revenue recognition guidance. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services. The standard is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted for the annual and interim periods beginning after December 15, 2016, but not prior to that time. The revenue recognition standard permits the use of either the retrospective or cumulative effect transition method. We expect to adopt this guidance when effective and are evaluating the impact, if any, of the adoption of the standard to our financial statements and related disclosures. We have not yet selected a transition method nor determined the effect of the standard on our ongoing financial reporting.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	(3) Fair Value Measurements Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement determined by assumptions that market participants would use in pricing an asset or liability. We categorize each of our fair value measurements in one of the following three levels based on the lowest level of input that is significant to the fair value measurement:  Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 — Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and Level 3 — Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions. At March 31, 2016 and December 31, 2015, we did not have any financial instruments required to be recorded at fair value on a recurring basis. The carrying amounts of cash, cash equivalents, receivables, accounts payable and accrued liabilities approximate fair values based on their short-term nature. The fair values of our revolving credit facility and capital leases are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to us for bank loans with similar terms and average maturities, the fair value of our revolving credit facility debt and capital leases, which are measured using Level 2 inputs, at March 31, 2016 and December 31, 2015 approximated their respective book values. The fair value of our $200.0 million aggregate principal amount of Senior Notes is based on their latest sales price at the end of each period obtained from a third-party institution and is Level 2 in the fair value hierarchy as there is not an active market for these notes. The Senior Notes are presented on the balance sheet net of debt issuance costs. The gross carrying value and the fair value of our Senior Notes are as follows: March 31, 2016 December 31, 2015 (In thousands) Carrying value $ 200,000 $ 200,000 Fair value 206,500 207,000

Earnings (Loss) Per Share

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	(4) Earnings (Loss) Per Share Basic earnings (loss) per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated under the treasury stock method. Potential common shares included restricted common stock, which is subject to risk of forfeiture, incremental shares of common stock issuable upon the exercise of stock options and vesting of restricted stock awards. The following table is a reconciliation of net income (loss) and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted EPS: Three Months Ended March 31, 2016 2015 (In thousands, except per share data) Numerator: Net income (loss) $ 10,998 $ (27,326 ) Denominator: Weighted average shares outstanding - basic 44,219 45,484 Dilutive effect of share-based awards 116 — Weighted average shares outstanding - diluted 44,335 45,484 Earnings (loss) per share: Basic $ 0.25 $ (0.60 ) Diluted 0.25 (0.60 ) Basic weighted average number of common shares outstanding does not include restricted stock awards of 0.3 million and 0.4 million shares as of March 31, 2016 and 2015, respectively. There were approximately 0.6 million of common stock equivalents that would have been included in the diluted EPS denominator for the three-month period ended March 31, 2015 had there not been a net loss. These common stock equivalents were excluded because their inclusion would reduce the net loss per share. In addition, the following table represents the number of stock options and restricted share awards that were issued or outstanding but excluded in calculating diluted EPS because their effect would have been anti-dilutive for the periods indicated: Three Months Ended March 31, 2016 2015 (In thousands) Stock options 3,153 1,108 Restricted share awards 19 — Total 3,172 1,108

Text Block [Abstract]
Impairment and Divestiture of North American Wood Mobile Offices	(5) Impairment and Divestiture of North American Wood Mobile Offices Our business strategy is to invest in high return, low maintenance, long-lived assets. Wood mobile offices require more maintenance and upkeep than Mobile Mini’s steel containers and steel ground level offices, resulting in lower margins as compared to our other portable storage products and our specialty containment products. During March 2015, we entered into discussions regarding the possible sale of our wood mobile offices within our North American portable storage segment. The discussions indicated that the fleet might be sold at an amount below carrying value. Based upon the events described above, we conducted a review for impairment for these particular long-lived assets as of March 31, 2015. The review included assumptions of cash flows considering the likelihood of possible outcomes that existed as of the date of the review, including assigning probabilities to these outcomes. Management estimated the fair market value for the wood mobile offices based upon purchase price discussions. Based on this review, management determined that the assets were impaired as of March 31, 2015 and an impairment loss was recognized. On April 16, 2015, we entered into a definitive agreement to sell our wood mobile offices within the North American portable storage segment for a cash price of $92.0 million, less associated deferred revenue and customer deposits of $6.8 million. The net assets were reclassified to held for sale as of that date. The transaction closed on May 15, 2015 and we recorded a net loss of $1.5 million on that date. For the three months ended March 31, 2015, the following amounts were recorded for the impairment of the wood mobile office fleet (in thousands): Estimated fair market value $ 92,000 Net book value: Wood mobile offices in rental fleet 155,558 Ancillary items in property, plant and equipment 1,168 Impairment loss $ (64,726 )

Business Combinations [Abstract]
Acquisitions	(6) Acquisitions During the three months ended March 31, 2016, we completed one acquisition of a portable storage business in Dallas, Texas. The accompanying condensed consolidated financial statements include the operations of the acquired business from the date of acquisition. The aggregate purchase price for the assets acquired were recorded based on their estimated fair values at the date of the acquisition. We have not disclosed the pro-forma impact of the acquisition on operations as they were immaterial to our financial position or results of operations in the aggregate. The components of the purchase price and net assets acquired during the three months ended March 31, 2016 are as follows (in thousands): Net Assets Acquired: Rental fleet $ 4,239 Property, plant and equipment 190 Intangible assets: Customer relationships 808 Non-compete agreements 50 Goodwill 3,676 Other assets 402 Liabilities (159 ) Total purchase price $ 9,206

Inventories	(7) Inventories Inventories are valued at the lower of cost (principally on a standard cost basis which approximates the first-in, first-out method) or net realizable value. Raw materials and supplies principally consist of raw steel, wood, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes and to a lesser extent, parts used for internal maintenance and ancillary items held for sale in our specialty containment segment. Work-in-process primarily represents partially assembled units pre-sold or for use as fleet. Finished portable storage units primarily represent purchased or assembled containers held in inventory until the container is either sold as is, remanufactured and sold, or remanufactured and deployed as rental fleet. Inventories at March 31, 2016 and December 31, 2015 consisted of the following: March 31, 2016 December 31, 2015 (In thousands) Raw materials and supplies $ 13,690 $ 13,436 Work-in-process 65 189 Finished portable storage units 1,671 1,971 Inventories $ 15,426 $ 15,596

Leases [Abstract]
Rental Fleet	(8) Rental Fleet Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred. We periodically review depreciable lives and residual values against various factors, including the results of our lenders’ independent appraisal of our rental fleet, practices of our competitors in comparable industries and profit margins achieved on sales of depreciated units. See Note 5 “Impairment and Divestiture of North American Wood Mobile Offices” for information regarding the impairment and divestiture of our wood mobile offices during 2015. Appraisals on our rental fleet are required by our lenders on a regular basis. The appraisal typically reports no difference in the value of the unit due to the age or length of time it has been in our fleet. The latest orderly liquidation value appraisal in September 2015 was conducted by Gordon Brothers-AccuVal. Based on the values assigned in this appraisal our rental fleet net orderly liquidation appraisal value as of March 31, 2016 was approximately $1.1 billion. These appraisals are used to calculate our available borrowings under our Amended and Restated ABL Credit Agreement, dated December 14, 2015, with Deutsche Bank AG New York Branch, as administrative agent, and the other lenders party thereto (the “Credit Agreement”), as described in Note 11 “Lines of Credit”. Depreciation expense related to our rental fleet for the three months ended March 31, 2016 and 2015 was $8.1 million and $9.2 million, respectively. At March 31, 2016, all rental fleet units were pledged as collateral under the Credit Agreement. Rental fleet consisted of the following at March 31, 2016 and December 31, 2015: Residual as Percentage of Original Cost (1) Useful Life in Years March 31, 2016 December 2015 (In thousands) Portable Storage: Steel storage containers 55% 30 $ 614,056 $ 612,782 Steel ground level offices 55% 30 349,196 346,233 Other 6,823 7,052 Total 970,075 966,067 Accumulated depreciation (142,785 ) (142,338 ) Total portable storage fleet, net $ 827,290 $ 823,729 Specialty Containment: Steel tanks 25 $ 56,761 $ 55,467 Roll-off boxes 15 - 20 28,226 25,161 Stainless steel tank trailers 25 29,188 28,160 Vacuum boxes 20 10,207 9,852 De-watering boxes 20 5,375 5,383 Pumps and filtration equipment 7 14,005 13,964 Other 7,507 6,843 Total 151,269 144,830 Accumulated depreciation (21,032 ) (17,236 ) Total specialty containment fleet, net $ 130,237 $ 127,594 Total rental fleet, net $ 957,527 $ 951,323 (1) Specialty containment fleet has been assigned zero residual value.

Property Plant And Equipment [Abstract]
Property, Plant and Equipment	(9) Property, Plant and Equipment Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives. Our depreciation expense related to property, plant and equipment for March 31, 2016 and 2015 was $5.5 million and $4.9 million, respectively. Normal repairs and maintenance to property, plant and equipment are expensed as incurred. When property or equipment is retired or sold, the net book value of the asset, reduced by any proceeds, is charged to gain or loss on the disposal of property, plant and equipment and is included in rental, selling and general expenses in the Condensed Consolidated Statements of Operations.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill and Intangibles	(10) Goodwill and Intangibles For acquired businesses, we record assets acquired and liabilities assumed at their estimated fair values on the respective acquisition dates. Based on these values, the excess purchase prices over the fair value of the net assets acquired is recorded as goodwill. Of the $708.6 million total goodwill at March 31, 2016, $467.6 million relates to the North America portable storage segment, $59.7 million relates to the U.K. portable storage segment and $181.2 million relates to the specialty containment segment. The following table shows the activity and balances related to goodwill from January 1, 2016 to March 31, 2016 (in thousands): Balance at January 1, 2016 $ 706,387 Acquisition 3,676 Foreign currency (1,500 ) Balance at March 31, 2016 $ 708,563 Intangible assets are amortized over the estimated useful life of the asset utilizing a method which reflects the estimated pattern in which the economic benefits will be consumed. Customer relationships are amortized based on the estimated attrition rates of the underlying customer base, other intangibles are amortized using the straight-line method. The following table reflects balances related to intangible assets for the periods presented: March 31, 2016 December 31, 2015 Estimated Useful Life Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount (In thousands) Customer relationships 11 - 20 $ 92,889 $ (25,936 ) $ 66,953 $ 92,304 $ (24,875 ) $ 67,429 Trade names/trademarks 5 - 10 6,002 (1,863 ) 4,139 6,025 (1,684 ) 4,341 Non-compete agreements 5 1,888 (526 ) 1,362 1,839 (433 ) 1,406 Other 20 60 (24 ) 36 60 (24 ) 36 Total $ 100,839 $ (28,349 ) $ 72,490 $ 100,228 $ (27,016 ) $ 73,212 Amortization expense for amortizable intangibles was approximately $1.6 million and $1.5 million for the three-month periods ended March 31, 2016 and 2015, respectively.

Lines of Credit	(11) Lines of Credit On December 14, 2015, we entered into the Credit Agreement. The Credit Agreement provides for a five-year, $1.0 billion first lien senior secured revolving credit facility maturing on or before the earlier of (i) December 14, 2020 and (ii) the date that is 90 days prior to the final maturity date of the Senior Notes if such Senior Notes remain outstanding on such date. The Credit Agreement also provides for the issuance of irrevocable standby letters of credit by U.S. lenders in amounts totaling up to $50.0 million, by U.K.-based lenders in amounts totaling up to $20.0 million, and by Canadian-based lenders in amounts totaling up to $20.0 million. The obligations of Mobile Mini and its subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of our assets. Amounts borrowed under the Credit Agreement and repaid or prepaid during the term may be reborrowed. Outstanding amounts under the Credit Agreement bear interest at our option at either: (i) the London interbank offered rate (“LIBOR”) plus an applicable margin (“LIBOR Loans”), or (ii) the prime rate plus an applicable margin (“Base Rate Loans”). The applicable margin for each type of loan is based on an availability-based pricing grid and ranges from 1.25% to 1.75% for LIBOR Loans and 0.25% to 0.75% for Base Rate Loans at each measurement date. Pursuant to the terms of the Credit Agreement, outstanding amounts will bear interest at the highest level in the pricing grid until the first measurement date subsequent to March 31, 2016. The margins in effect as of April 2016 are 1.50% for LIBOR Loans and 0.50% for Base Rate Loans. Availability of borrowings under the Credit Agreement is subject to a borrowing base calculation based upon a valuation of the Company’s eligible accounts receivable, eligible container fleet (including containers held for sale, work-in-process and raw materials) and machinery and equipment, each multiplied by an applicable advance rate or limit. The rental fleet is appraised at least once annually by a third-party appraisal firm and up to 90% of the Net Orderly Liquidation Value, as defined in the Credit Agreement, is included in the borrowing base to determine how much the Company may borrow under the Credit Agreement. The Credit Agreement provides for U.K. borrowings, which are, at the Company’s option, denominated in either Pounds Sterling or Euros, by its U.K. subsidiary based upon a U.K. borrowing base; Canadian borrowings, which are denominated in Canadian dollars, by its Canadian subsidiary based upon a Canadian borrowing base; and U.S. borrowings, which are denominated in U.S. dollars, by the Company based upon a U.S. borrowing base along with any Canadian assets not included in the Canadian subsidiary. The Credit Agreement also contains customary negative covenants, including covenants that restrict our ability to, among other things: (i) allow certain liens to attach to Mobile Mini or subsidiary assets, (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, or prepay certain indebtedness, (iii) incur additional indebtedness or engage in certain other types of financing transactions, and (iv) make acquisitions or other investments. In addition, we must comply with a minimum fixed charge coverage ratio of 1.00 to 1.00 as of the last day of each quarter, upon the minimum availability amount under the Credit Agreement falling below the greater of (y) $90.0 million and (z) 10% of the lesser of the then total revolving loan commitment and aggregate borrowing base. As of March 31, 2016, we were in compliance with the minimum borrowing availability threshold as set forth in the Credit Agreement and therefore not subject to any financial maintenance covenants.

Income Tax Disclosure [Abstract]
Income Taxes	(12) Income Taxes We file U.S. federal tax returns, U.S. state tax returns and foreign tax returns and have identified our U.S. federal tax return as our “major” tax jurisdiction. For the U.S. federal return, our tax years for 2012, 2013 and 2014 are subject to tax examination by the U.S. Internal Revenue Service through September 15, 2016, 2017 and 2018, respectively. We do not anticipate that the total amount of unrecognized tax benefit related to any particular tax position will change significantly within the next 12 months. We use a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Our policy for recording interest and penalties associated with audits is to record such items as a component of income before taxes. Penalties and associated interest costs, if any, are recorded in rental, selling and general expenses in our Condensed Consolidated Statements of Operations.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation	(13) Share-Based Compensation We have historically awarded stock options and restricted stock awards for employees and non-employee directors as a means of attracting and retaining quality personnel and to align employee performance with stockholder value. Stock option plans are approved by our stockholders and administered by the stock compensation committee of the Company’s Board of Directors (the “Board”). The current plan allows for a variety of equity programs designed to provide flexibility in implementing equity and cash awards, including incentive stock options, nonqualified stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance stock, performance units and other stock-based awards. Participants may be granted any one of the equity awards or any combination. We do not award stock options with an exercise price below the market price of the underlying securities on the date of award. As of March 31, 2016, 1.9 million shares are available for future grants. Generally stock options have contractual terms of ten years. For the quarters ended March 31, 2016 and 2015, expense related to share-based compensation was $2.6 million and $3.3 million, respectively. This expense was included in rental, selling and general expenses for these quarters. As of March 31, 2016, total unrecognized compensation cost related to stock option awards was approximately $5.9 million and the related weighted-average period over which it is expected to be recognized is approximately 1.8 years. As of March 31, 2016, the unrecognized compensation cost related to restricted stock awards was approximately $8.2 million, which is expected to be recognized over a weighted-average period of approximately 2.8 years. Stock Options. The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes-Merton option pricing model which requires the input of assumptions. We estimate the risk-free interest rate based on the U.S. Treasury security rate in effect at the time of the grant. The expected life of the options, volatility and dividend rates are estimated based on our historical data. The following are the key assumptions used for the period noted: 2016 2015 Risk-free interest rate 1.5% 1.3% - 1.5% Expected life of the options (years) 5 5 Expected stock price volatility 36.7% 35.6% - 35.7% Expected dividend rate 3.1% 1.8% - 2.0% The following table summarizes stock option activity for the three months ended March 31, 2016 (share amounts in thousands): Number of Shares Weighted Average Exercise Price Options outstanding, beginning of period 2,870 $ 33.40 Granted 574 26.20 Canceled/Expired (26 ) 34.75 Exercised — Options outstanding, end of period 3,418 32.18 A summary of stock options outstanding as of March 31, 2016, is as follows: Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Terms Aggregate Intrinsic Value (In thousands) (In years) (In thousands) Outstanding 3,418 $ 32.18 7.60 $ 11,546 Vested and expected to vest 3,295 32.27 7.53 10,881 Exercisable 2,512 32.01 6.97 7,614 The weighted average fair value of stock options granted was $6.54. Included in the tables above are option awards granted in 2016 which will vest based upon the achievement of specified performance criteria related to 2016 and future years. Such awards have been granted assuming a target number of options; however, the terms of these awards provide that the number of options that ultimately vest may vary between 50% and 200% of the target award, or may be zero. The tables present the options at their target amount, and the 1.9 million shares available for grant as noted previously, has also been calculated utilizing the target award amounts. Included in the cancellations shown in the table above is the cancellation of approximately 13,000 options granted in previous years subject to performance criteria. These awards were canceled during the current period due to vesting at less than 100% of the target award. Restricted Stock Awards. The fair value of restricted stock awards is estimated as the closing price of our common stock on the date of grant. A summary of restricted stock award activity is as follows (share amounts in thousands): Shares Weighted Average Grant Date Fair Value Restricted stock awards at beginning of period 242 $ 31.70 Awarded 143 26.23 Released (54 ) 33.25 Forfeited (9 ) 25.97 Restricted stock awards at end of period 322 29.16 The restricted stock awards that vested during the three months ended March 31, 2016 had an aggregate grant date fair value of $1.8 million and an aggregate vesting date fair value of $1.6 million.

Restructuring And Related Activities [Abstract]
Restructuring	(14) Restructuring We have undergone restructuring actions to align our business operations. The restructuring expense during the three-month period ended March 31, 2016 resulted from the continuation of restructuring projects initiated in prior years. These costs include additional restructuring items that were included in the prior year plan but were not accruable at the time of the previous charges. Of the $2.2 million of restructuring expense recognized in the three months ended March 31, 2016 approximately $1.3 million related to the integration of Evergreen Tank Solutions (“ETS”) into the existing Mobile Mini infrastructure, including our shift from managing operations on a product-oriented basis to a geographic, customer-focused organization; and, to support this shift, the re-alignment of sales leadership with operational leadership. The remaining costs largely relate to the abandonment of yards related to our move away from the wood mobile office business. The restructuring expense recognized in the three months ended March 31, 2015 related primarily to the ETS integration. The following table details accrued restructuring obligations (included in accrued liabilities in the Condensed Consolidated Balance Sheets) and related activity for the year ended December 31, 2015 and the three-month period ended March 31, 2016: Fleet Plant and Equipment Abandonment Costs Severance Benefits Lease Abandonment Costs Other Costs Total (In thousands) Accrued obligations as of January 1, 2015 $ — $ 441 $ 676 $ — $ 1,117 Restructuring expense 15,274 4,846 600 78 20,798 Settlement of obligations (15,274 ) (4,042 ) (781 ) (76 ) (20,173 ) Accrued obligations as of December 31, 2015 — 1,245 495 2 1,742 Restructuring expense 106 72 736 1,334 2,248 Settlement of obligations (106 ) (364 ) (780 ) (288 ) (1,538 ) Accrued obligations as of March 31, 2016 $ — $ 953 $ 451 $ 1,048 $ 2,452 The majority of accrued obligations are expected to be paid out through the year 2016, with the exception of a lease that will continue into the first quarter of 2019.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(15) Commitments and Contingencies We are a party to various claims and litigation in the normal course of business. Our current estimated range of liability related to various claims and pending litigation is based on claims for which our management can determine that it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Because of the uncertainties related to both the probability of incurred and possible range of loss on pending claims and litigation, management must use considerable judgment in making reasonable determination of the liability that could result from an unfavorable outcome. As additional information becomes available, we will assess the potential liability related to our pending litigation and revise our estimates. Such revisions in our estimates of the potential liability could materially impact our results of operation. We do not anticipate the resolution of such matters known at this time will have a material adverse effect on our business or consolidated financial position.

Equity [Abstract]
Stockholders' Equity	(16) Stockholders’ Equity Dividends On January 21, 2016, the Board authorized and declared a cash dividend to all our common stockholders of $0.206 per share of common stock. These dividends were payable on March 23, 2016 to all stockholders of record as of the close of business on March 9, 2016. Each future quarterly dividend payment is subject to review and approval by the Board. The Company’s Credit Agreement contains restrictions on the declaration and payment of dividends. Treasury Stock On November 6, 2013, the Board approved a share repurchase program authorizing up to $125.0 million of our outstanding shares of common stock to be repurchased. On April 17, 2015, the Board authorized up to an additional $50.0 million of our outstanding shares of common stock to be repurchased, for a total of $175.0 million under the share repurchase program. The shares may be repurchased from time to time in the open market or in privately negotiated transactions. The share repurchases are subject to prevailing market conditions and other considerations. The share repurchase program does not have an expiration date and may be suspended or terminated at any time by the Board. All shares repurchased are held in treasury. During the three months ended March 31, 2016, we purchased approximately 0.3 million shares of our common stock at a cost of $6.8 million under the authorized share repurchase program, and approximately $82.2 million is available for repurchase as of March 31, 2016. In addition, we withheld approximately 11,000 shares of stock from employees, for an approximate value of $0.3 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program. During the three months ended March 31, 2015, we purchased approximately 0.4 million shares of our common stock at a cost of $15.0 million under the authorized share repurchase program and withheld approximately 7,000 shares of stock from employees, for an approximate value of $0.3 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program.

Segment Reporting [Abstract]
Segment Reporting	(17) Segment Reporting Our operations are comprised of three reportable segments: North American portable storage, U.K. portable storage and specialty containment. Discrete financial data on each of our products is not available and it would be impractical to collect and maintain financial data in such a manner. The results for each segment are reviewed discretely by our chief operating decision maker. We operate in the U.S., U.K. and Canada. All of our locations operate in their local currency and, although we are exposed to foreign exchange rate fluctuation in foreign markets where we rent and sell our products, we do not believe such exposure will have a significant impact on our results of operations. Revenues recognized by our U.S. locations were $103.1 million and $110.5 million for the three months ended March 31, 2016 and 2015, respectively.

Mobile Mini, Inc. - Organization and Description of Business (Policies)	3 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements include the accounts of Mobile Mini and our wholly owned subsidiaries. We do not have any subsidiaries in which we do not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management of Mobile Mini, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows for all periods presented have been made. The results of operations for the three months ended March 31, 2016 and 2015 are not necessarily indicative of the results to be expected for the full year. These condensed consolidated financial statements should be read in conjunction with our December 31, 2015 audited consolidated financial statements and accompanying notes thereto, which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 5, 2016.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and the notes to those statements. Actual results could differ from those estimates. Significant estimates affect the calculation of depreciation and amortization, the calculation of the allowance for doubtful accounts, the analysis of goodwill and long-lived assets for potential impairment and certain accrued liabilities.
Reclassifications	Reclassifications Certain amounts in the Condensed Consolidated Statements of Operations for the three months ended March 31, 2015 have been reclassified to conform to the current period presentation. The reclassifications have no effect on total revenues, loss from operations, net loss or net loss per common share. For the previously reported three-month period ended March 31, 2015, the reclassifications resulted in $2.1 million and $1.2 million increases to rental revenues and sales revenues, respectively, with an offsetting decrease to other revenue. For the same period, cost of sales increased $0.9 million, and rental, selling and general expenses decreased by the same amount. The revenues reclassified to rental revenues from other revenues consist of ancillary services such as equipment cleaning fees and equipment installation. The items reclassified from other revenues to sales include sales of certain ancillary products. Costs associated with these sales have also been reclassified to cost of sales from rental, selling and general expenses. We believe the current presentation better reflects the nature of the underlying financial statement items.
Fair Value Measurements, Policy	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement determined by assumptions that market participants would use in pricing an asset or liability. We categorize each of our fair value measurements in one of the following three levels based on the lowest level of input that is significant to the fair value measurement:  Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 — Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and Level 3 — Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.
Earnings Per Share	Basic earnings (loss) per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated under the treasury stock method. Potential common shares included restricted common stock, which is subject to risk of forfeiture, incremental shares of common stock issuable upon the exercise of stock options and vesting of restricted stock awards.
Inventories	Inventories are valued at the lower of cost (principally on a standard cost basis which approximates the first-in, first-out method) or net realizable value. Raw materials and supplies principally consist of raw steel, wood, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes and to a lesser extent, parts used for internal maintenance and ancillary items held for sale in our specialty containment segment. Work-in-process primarily represents partially assembled units pre-sold or for use as fleet. Finished portable storage units primarily represent purchased or assembled containers held in inventory until the container is either sold as is, remanufactured and sold, or remanufactured and deployed as rental fleet.
Property, Plant and Equipment	Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives. Our depreciation expense related to property, plant and equipment for March 31, 2016 and 2015 was $5.5 million and $4.9 million, respectively. Normal repairs and maintenance to property, plant and equipment are expensed as incurred. When property or equipment is retired or sold, the net book value of the asset, reduced by any proceeds, is charged to gain or loss on the disposal of property, plant and equipment and is included in rental, selling and general expenses in the Condensed Consolidated Statements of Operations. See Note 5 “Impairment and Divestiture of North American Wood Mobile Offices” for information regarding the impairment and divestiture of ancillary equipment related to our wood mobile offices during 2015.
Income Tax Uncertainties, Policy	We use a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.
Segment Reporting, Policy	Our operations are comprised of three reportable segments: North American portable storage, U.K. portable storage and specialty containment. Discrete financial data on each of our products is not available and it would be impractical to collect and maintain financial data in such a manner. The results for each segment are reviewed discretely by our chief operating decision maker. We operate in the U.S., U.K. and Canada. All of our locations operate in their local currency and, although we are exposed to foreign exchange rate fluctuation in foreign markets where we rent and sell our products, we do not believe such exposure will have a significant impact on our results of operations. Revenues recognized by our U.S. locations were $103.1 million and $110.5 million for the three months ended March 31, 2016 and 2015, respectively.
Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards Share-Based Compensation. In March 2016, the Financial Accounting Standards Board (“FASB”) issued a standard intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. This standard is effective for annual and interim periods beginning after December 15, 2016, and early adoption is permitted. We are currently evaluating the impact that the standard will have on our consolidated financial statements. Leases . In February 2016, FASB issued a standard on lease accounting requiring a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. This standard is effective for annual and interim periods beginning after December 15, 2018, and early adoption is permitted. We are currently evaluating the impact the standard will have on our consolidated financial statements. Simplifying the Presentation of Debt Issuance Costs . In April 2015, FASB issued accounting guidance on the presentation of debt issuance costs in the balance sheet. This standard requires that certain debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. We adopted this guidance during the current period. As a result, unamortized debt issuance costs of $2.3 million and $2.4 million as of March 31, 2016 and December 31, 2015, respectively, have been deducted from the carrying amount of our 7.875% senior notes due 2020 (the “Senior Notes”) in our balance sheet. Unamortized debt issuance costs related to our revolving lines of credit are included in other assets. Revenue from Contracts with Customers . In May 2014, FASB issued an accounting standard on revenue from contracts with customers. The standard provides a single model for revenue arising from contracts with customers and supersedes current revenue recognition guidance. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services. The standard is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted for the annual and interim periods beginning after December 15, 2016, but not prior to that time. The revenue recognition standard permits the use of either the retrospective or cumulative effect transition method. We expect to adopt this guidance when effective and are evaluating the impact, if any, of the adoption of the standard to our financial statements and related disclosures. We have not yet selected a transition method nor determined the effect of the standard on our ongoing financial reporting.
Rental Fleet, Policy	Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred. We periodically review depreciable lives and residual values against various factors, including the results of our lenders’ independent appraisal of our rental fleet, practices of our competitors in comparable industries and profit margins achieved on sales of depreciated units.
