Basis of Presentation	'
	NOTE A — Basis of Presentation
	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, Inc. (referred to herein as “Mobile Mini,” “us,” “we,” “our” or the “Company”), 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. All significant inter-company balances and transactions have been eliminated.
	The local currency of the Company’s foreign operations is translated to U.S. currency for the Company’s condensed consolidated financial statements for each period being presented, and the Company is subject to foreign exchange rate fluctuations in connection with the Company’s European and Canadian operations.
	The Condensed Consolidated Balance Sheet at December 31, 2012 was derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.
	The results of operations for the three- and nine-month periods ended September 30, 2013 are not necessarily indicative of the operating results that may be expected for the full fiscal year ending December 31, 2013 or any future period. Demand from certain of the Company’s customers is somewhat seasonal. Demand for leases of the Company’s portable storage units by large retailers is stronger from September through December because these retailers need to store additional inventory for the holiday season. These retailers usually return these leased units to the Company in December or early in the following year. This seasonality has historically caused lower utilization rates for the Company’s lease fleet during the first quarter of each year.
	These condensed consolidated financial statements should be read in conjunction with the Company’s December 31, 2012 audited consolidated financial statements and accompanying notes thereto, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 1, 2013.

	NOTE B — Recent Accounting Pronouncements
	Comprehensive Income. In June 2011, the Financial Accounting Standards Board (“FASB”) issued an amendment to the existing guidance on the presentation of comprehensive income. Under the amended guidance, an entity is required to present the effect of reclassification adjustments out of accumulated other comprehensive income in both net income and other comprehensive income in the financial statements. In February 2013, the FASB issued an amendment to this provision which is effective on a prospective basis for fiscal years, and interim periods within those years, beginning after December 15, 2012. The adoption of this amendment did not have a material impact on the Company’s consolidated financial statements and related disclosures.

Fair Value Measurements

'

NOTE C — Fair Value Measurements

The Company defines fair value as 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 that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company adopted the suggested accounting guidance for the three levels of inputs that may be used to measure fair value:

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 December 31, 2012 and September 30, 2013, the Company did not have any financial instruments required to be recorded at fair value on a recurring basis.

The following table summarizes our non-financial assets measured at fair value on a non-recurring basis:

Assets held for sale primarily represent portable storage and office units and some transportation equipment. The carrying value of these assets was written down to fair value in the second quarter of 2013 and the resulting impairment loss was recorded in the asset impairment charge in the Condensed Consolidated Statements of Income. Our estimate of the fair value of the assets held for sale is based on our understanding of market prices to be paid by third parties (See Note O).

Fair Value of Financial Instruments	'
	NOTE D — Fair Value of Financial Instruments
	The Company determines the estimated fair value of financial instruments using available market information and valuation methodologies. Considerable judgment is required in estimating fair values. Accordingly, the estimates may not be indicative of the amounts the Company could realize in current market exchanges.
	The carrying amounts of cash, receivables, accounts payable and accrued liabilities approximate fair values based on the liquidity of these financial instruments or based on their short-term nature. The carrying amounts of the Company’s borrowings under its revolving credit facility, notes payable and capital leases approximate fair value. The fair values of the Company’s revolving credit facility, notes payable and capital leases are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company’s revolving credit facility debt, notes payable and capital leases at December 31, 2012 and September 30, 2013 approximated their respective book values and are considered Level 2 in the fair value hierarchy described in Note C.
	The fair value of the Company’s $200.0 million aggregate principal amount of 7.875% senior notes due 2020 (the “Senior Notes”) is $219.0 million and $218.0 million as of December 31, 2012 and September 30, 2013, respectively. The fair value is based on the latest sales price of such notes at the end of each period obtained from a third-party institution and is considered Level 2 in the fair value hierarchy described in Note C, as there is not an active market for such notes.

Earnings Per Share	'
	NOTE E — Earnings Per Share
	Basic earnings 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 include 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 nonvested stock awards.
	The following is a reconciliation of weighted-average shares of common stock outstanding for purposes of calculating basic and diluted EPS for the three- and nine-month periods ended September 30, 2012 and 2013:

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]	'
Share-Based Compensation	'
	NOTE F — Share-Based Compensation
	At September 30, 2013, the Company had one active share-based employee compensation plan. There are two expired compensation plans, one of which still has outstanding options subject to exercise or termination. No additional options can be granted under the expired plans.
	Stock option awards under these plans were granted with an exercise price per share equal to the fair market value of the Company’s common stock on the date of grant. Each outstanding option must expire no later than ten years from the date it was granted, unless exercised or forfeited before the expiration date, and are granted with vesting periods ranging from three to four and a half years. The total value of the Company’s stock option awards is expensed over the related employee’s service period on a straight-line basis, or if subject to performance conditions, the expense is recognized using the accelerated attribution method. The “service period” is the time during which the employees receiving the awards must remain employed for the shares granted to fully vest.
	The Company also awards restricted stock, also called nonvested share-awards in this discussion, under the existing share-based compensation plan. The majority of the Company’s nonvested share-awards vest in equal annual installments over a four- to five-year period. The total value of these time-based awards is expensed on a straight-line basis over the service period of the employees receiving the awards.
	The Company also grants certain executive officers stock options and nonvested share-awards with vesting subject to performance conditions. Vesting of these grants is dependent upon the respective officers fulfilling the service period requirements as well as the Company achieving certain yearly adjusted EBITDA targets in each of the performance periods (three to four years) after the grant is awarded. EBITDA is defined as net income before interest expense, income taxes, depreciation and amortization and debt restructuring or extinguishment expense, including any write-off of deferred financing costs, and further adjusted for specific transactions, to arrive at adjusted EBITDA. For performance-based grants, the Company is required to assess the probability that such performance conditions will be met. If the likelihood of the performance conditions being met is deemed probable, the Company will recognize the expense using the accelerated attribution method. The accelerated attribution method could result in as much as 60% of the total value of the shares being recognized in the first year of the service period if the future performance-based targets are assessed as probable of being met.
	The following table sets forth unrecognized compensation costs related to the Company’s share-based compensation plan as of September 30, 2013:
		September 30,			Weighted Average

Inventories	'
	NOTE G — Inventories
	Inventories are valued at the lower of cost (principally on a standard cost basis that approximates the first-in, first-out, or FIFO, method) or market. Market is the lower of replacement cost or net realizable value. Inventories primarily consist of raw materials and supplies, work-in-process and finished portable storage units, all related to manufacturing, remanufacturing and maintenance, primarily for the Company’s lease fleet and its units held for sale. Raw materials and supplies principally consist of raw steel, wood, glass, paint and other assembly components used in manufacturing and remanufacturing processes. Work-in-process primarily represents units being built that are either pre-sold or being built to add to the Company’s lease fleet upon completion. Finished portable storage units primarily represent ISO, or International Organization for Standardization, containers held in inventory until the containers are either sold as is, remanufactured and sold, or units in the process of being remanufactured to be compliant with the Company’s lease fleet standards before transferring the units to its lease fleet. There is no certainty when the Company purchases the containers whether they will ultimately be sold, remanufactured and sold, or remanufactured and moved into its lease fleet. Units that are placed into the Company’s lease fleet undergo an extensive remanufacturing process that includes installing its proprietary locking system, signage, painting and sometimes its proprietary security doors. Inventories consisted of the following at the dates indicated:

Lease Fleet	'
	NOTE H — Lease Fleet
	The Company has a lease fleet primarily consisting of remanufactured and modified steel portable storage containers, steel security offices, steel combination offices and wood mobile offices that are leased to customers under short-term operating lease agreements with varying terms. Depreciation is calculated using the straight-line method over the estimated useful life of the Company’s units, after the date the units are placed in service, and are depreciated down to their estimated residual values. The Company’s steel units are depreciated over 30 years with an estimated residual value of 55%. Wood office units are depreciated over 20 years with an estimated residual value of 50%. Van trailers, which are a small part of the Company’s fleet, are depreciated over seven years to an estimated residual value of 20%. The Company has other non-core products that have various other measures of useful lives and residual values. Van trailers and other non-core assets are typically only added to the fleet as a result of acquisitions of portable storage businesses.
	In the opinion of management, estimated residual values do not cause carrying values to exceed net realizable value. The Company continues to evaluate these depreciation policies as more information becomes available from other comparable sources and the Company’s own historical experience. Normal repairs and maintenance to the portable storage containers and mobile office units are expensed as incurred.

	NOTE I — Property, Plant and Equipment
	Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the assets’ estimated useful lives. Residual values are determined when the property is constructed or acquired and range up to 25%, depending on the nature of the asset. In the opinion of management, estimated residual values do not cause carrying values to exceed net realizable value. 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 retirement of fixed assets and is included in leasing, selling and general expenses in the accompanying Condensed Consolidated Statements of Income. Property, plant and equipment consisted of the following at the dates indicated:

Lines of Credit	'
	NOTE J — Lines of Credit
	The Company has a $900.0 million ABL Credit Agreement with Deutsche Bank AG New York Branch and other lenders party thereto (the “Credit Agreement”). The Credit Agreement provides for a five-year revolving credit facility and matures on February 22, 2017. The obligations of Mobile Mini and its subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of its 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 the Company’s option at either: (i) LIBOR plus a defined margin, or (ii) the Agent bank’s prime rate plus a margin. The applicable margin for each type of loan is based on an availability-based pricing grid and ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to 1.25% for base rate loans at each measurement date. As of September 30, 2013, the applicable margins were 2.00% for LIBOR loans and 1.00% for base rate loans and will be remeasured at the end of the next measurement date, which is within 10 days following the end of each fiscal quarter.
	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 lease 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.
	The Credit Agreement also contains customary negative covenants, including covenants that restrict the Company’s ability to, among other things: (i) allow certain liens to attach to the Company or its subsidiary assets; (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, prepay certain indebtedness or make acquisitions or other investments subject to Payment Conditions (as defined in the Credit Agreement); and (iii) incur additional indebtedness or engage in certain other types of financing transactions. Payment Conditions allow restricted payments and acquisitions to occur without financial covenants as long as the Company has $225.0 million of pro forma excess borrowing availability under the Credit Agreement. The Company must also comply with specified financial maintenance covenants and affirmative covenants if the Company falls below $90.0 million of borrowing availability levels with set permitted values for the Debt Ratio and Fixed Charge Coverage Ratio (each as defined in the Credit Agreement). The Company was in compliance with the terms of the Credit Agreement as of September 30, 2013 and was above the minimum borrowing availability threshold and therefore not subject to any financial maintenance covenants or restricted from paying dividends or making stock repurchases.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	NOTE K — Income Taxes
	The Company files U.S. Federal tax returns, U.S. state tax returns and foreign tax returns. The Company has identified its U.S. Federal tax return as its “major” tax jurisdiction. For the U.S. Federal return, its tax years for 2010, 2011 and 2012 are subject to tax examination by the U.S. Internal Revenue Service through September 15, 2014, 2015 and 2016, respectively. The Company does not anticipate that the total amount of unrecognized tax benefit related to any particular tax position will change significantly within the next 12 months.
	The Company uses 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.
	In July 2013, the U.K.’s government authorized another reduction in the corporate income tax rate from the statutory rate of 23%, authorized in 2012, to 20%. These rate reductions only affected the Company’s U.K. operations and reduced the Company’s deferred tax liability in the U.K. by approximately $1.2 million and $1.9 million in 2012 and 2013, respectively. The tax reductions are reflected at the enacted rate in effect at the estimated date such amounts will be payable. The benefit of these rate changes is included in the 2012 and 2013 tax provisions.
	The Company’s 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 leasing, selling and general expenses in its Condensed Consolidated Statements of Income.

Segment Reporting	'
	NOTE M — Segment Reporting
	The Company has operations in North America, the U. K. and The Netherlands. The Company’s operating segments are similarly defined geographically. Discrete financial data on each of the Company’s products is not available and it would be impractical to collect and maintain financial data in such a manner. Financial results of the three operating segments are aggregated into two reportable segments, North America and Europe, based on quantitative thresholds. All of the Company’s locations operate in their local currency and, although the Company is exposed to foreign exchange rate fluctuation in other foreign markets where the Company leases and sells its products, the Company does not believe such exposure will have a significant impact on its results of operations.
	In managing the Company’s business, management focuses on growing leasing revenues, particularly in existing markets where it can take advantage of the operating leverage inherent in its business model, EBITDA and consolidated EPS.
	The following tables set forth certain information regarding each of the Company’s segments for the three- and nine-month periods ended September 30, 2012 and 2013:

Accounting Policies [Abstract]	'
Fair Value of Financial Instruments	'
	The Company determines the estimated fair value of financial instruments using available market information and valuation methodologies. Considerable judgment is required in estimating fair values. Accordingly, the estimates may not be indicative of the amounts the Company could realize in current market exchanges.
	The carrying amounts of cash, receivables, accounts payable and accrued liabilities approximate fair values based on the liquidity of these financial instruments or based on their short-term nature. The carrying amounts of the Company’s borrowings under its revolving credit facility, notes payable and capital leases approximate fair value. The fair values of the Company’s revolving credit facility, notes payable and capital leases are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company’s revolving credit facility debt, notes payable and capital leases at December 31, 2012 and September 30, 2013 approximated their respective book values and are considered Level 2 in the fair value hierarchy described in Note C.
	The fair value of the Company’s $200.0 million aggregate principal amount of 7.875% senior notes due 2020 (the “Senior Notes”) is $219.0 million and $218.0 million as of December 31, 2012 and September 30, 2013, respectively. The fair value is based on the latest sales price of such notes at the end of each period obtained from a third-party institution and is considered Level 2 in the fair value hierarchy described in Note C, as there is not an active market for such notes.
Earnings Per Share	'
	Basic earnings 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 include 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 nonvested stock awards.
Inventories	'
	Inventories are valued at the lower of cost (principally on a standard cost basis that approximates the first-in, first-out, or FIFO, method) or market. Market is the lower of replacement cost or net realizable value. Inventories primarily consist of raw materials and supplies, work-in-process and finished portable storage units, all related to manufacturing, remanufacturing and maintenance, primarily for the Company’s lease fleet and its units held for sale. Raw materials and supplies principally consist of raw steel, wood, glass, paint and other assembly components used in manufacturing and remanufacturing processes. Work-in-process primarily represents units being built that are either pre-sold or being built to add to the Company’s lease fleet upon completion. Finished portable storage units primarily represent ISO, or International Organization for Standardization, containers held in inventory until the containers are either sold as is, remanufactured and sold, or units in the process of being remanufactured to be compliant with the Company’s lease fleet standards before transferring the units to its lease fleet. There is no certainty when the Company purchases the containers whether they will ultimately be sold, remanufactured and sold, or remanufactured and moved into its lease fleet. Units that are placed into the Company’s lease fleet undergo an extensive remanufacturing process that includes installing its proprietary locking system, signage, painting and sometimes its proprietary security doors.
Property, Plant and Equipment	'
	Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the assets’ estimated useful lives. Residual values are determined when the property is constructed or acquired and range up to 25%, depending on the nature of the asset. In the opinion of management, estimated residual values do not cause carrying values to exceed net realizable value. 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 retirement of fixed assets and is included in leasing, selling and general expenses in the accompanying Condensed Consolidated Statements of Income.

	-1	Assets held for sale primarily represent portable storage and office units and some transportation equipment. The carrying value of these assets was written down to fair value in the second quarter of 2013 and the resulting impairment loss was recorded in the asset impairment charge in the Condensed Consolidated Statements of Income. Our estimate of the fair value of the assets held for sale is based on our understanding of market prices to be paid by third parties (See Note O).

Condensed Consolidating Balance Sheets	'
	The following tables reflect the condensed consolidating financial information of the Company’s subsidiary guarantors of the Senior Notes and its non-guarantor subsidiaries. Separate financial statements of the subsidiary guarantors are not presented because the guarantee by each 100% owned subsidiary guarantor is full and unconditional, joint and several, subject to customary exceptions, and management has determined that such information is not material to investors. On December 31, 2012, the assets and liabilities of our Toronto, Canada location, which was part of the U.S. guarantor Company, were transferred to our Canadian subsidiary, Mobile Mini Canada ULC, which is a non-guarantor subsidiary of the Senior Notes.
