Basis Of Presentation [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The accompanying consolidated financial statements should be read in conjunction with the Annual Report on Form 10-K for the fiscal year ended December 31, 2014 for SBA Communications Corporation and its subsidiaries (the “Company”). These financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, omit or condense certain footnotes and other information normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States. In the opinion of the Company’s management, all adjustments (consisting of normal recurring accruals) considered necessary for fair financial statement presentation have been made. The results of operations for an interim period may not give a true indication of the results for the year. Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year. The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in consolidated financial statements and accompanying notes. While the Company believes that such estimates are fair when considered in conjunction with the consolidated financial statements and accompanying notes, the actual amounts, when known, may vary from these estimates. Foreign Currency Translation All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency (Brazil and Canada) are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the period. Unrealized translation gains and losses are reported as foreign currency translation adjustments through Accumulated other comprehensive loss in the accompanying Consolidated Statement of Shareholders’ Deficit. Intercompany Loans In accordance with Accounting Standards Codification (ASC) 830, the Company remeasures intercompany loans not denominated in the functional currency with the corresponding remeasurement adjustment being recorded in Other income (expense), net in the Consolidated Statements of Operations. For the three and nine months ended September 30, 2015 , the Company recorded a $112.1 million and $180.4 million foreign exchange loss, respectively, on the remeasurement of an intercompany loan with a Brazilian subsidiary. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board ("FASB") released updated guidance regarding the recognition of revenue from contracts with customers, exclusive of those contracts within lease accounting. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contracts with the customer; (2) identify the performance obligations in the contract; (3) determine the contract price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The new guidance is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 for public companies. Under the proposal, the standard would be required to be adopted by public business entities in annual periods beginning on or after December 15, 2017. Early adoption is permitted but not before interim and annual reporting periods beginning after December 15, 2016. This guidance is required to be applied (1) retrospectively to each prior reporting period presented, or (2) with the cumulative effect being recognized at the date of initial application. The Company is evaluating the guidance including the impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest. The standard requires debt issuance costs to be presented on the balance sheet as a direct deduction from the related debt liability rather than as an asset. Once adopted, entities are required to apply the new guidance retrospectively to all prior periods presented. ASU 2015-03 is effective for annual and interim periods beginning after December 15, 2015 and early application is permitted. The Company has not elected to early adopt the standard. In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest - Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. The standard indicates the SEC staff would not object to presenting deferred debt issuance costs for a line of credit arrangement as an asset in the balance sheet. ASU 2015-15 is effective for annual and interim periods beginning after December 15, 2015 and early application is permitted. The Company has not elected to early adopt the standard. In September 2015, the FASB issued ASU 2015-16 Business Combinations. The standard requires that the acquirer (1) recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, (2) record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date, and (3) to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for annual and interim periods beginning after December 15, 2015 and early application is permitted. The Company has not elect ed to early adopt the standard.

Fair Value Measurements

Fair Value Measurements [Abstract]
Fair Value Measurements	2. FAIR VALUE MEASUREMENTS Items Measured at Fair Value on a Recurring Basis — The Company’s earnout liabilities related to acquisitions are measured at fair value on a recurring basis using Level 3 inputs and are recorded in Accrued expenses in the accompanying Consolidated Balance Sheets. Changes in estimate are recorded in Acquisition related adjustments and expenses in the accompanying Consolidated Statement of Operations. The Company determines the fair value of acquisition-related earnouts (contingent consideration) and any subsequent changes in fair value using a discounted probability-weighted approach using Level 3 inputs. Level 3 valuations rely on unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The fair value of the earnouts is reviewed quarterly and is based on the payments the Company expects to make based on historical internal observations related to the anticipated performance of the underlying assets. The Company’s estimate of the fair value of its obligation of performance targets contained in various acquisitions was $8.8 million and $15.1 million as of September 30, 2015 and December 31, 2014 . The maximum potential obligation related to the performance targets was $14.3 million and $23.1 million as of September 30, 2015 and December 31, 2014 , respectively. The following summarizes the activity of the accrued earnouts: 2015 2014 (in thousands) Beginning balance, December 31, 2014 and 2013 , respectively $ $ Additions Payments Change in estimate Foreign currency translation adjustments Ending balance, September 30, 2015 and September 30, 2014, respectively $ $ Items Measured at Fair Value on a Nonrecurring Basis — The Company’s long-lived assets, intangibles, and asset retirement obligations are measured at fair value on a nonrecurring basis using Level 3 inputs. The Company considers many factors and makes certain assumptions when making this assessment, including but not limited to: general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. The fair value of the long-lived assets, intangibles, and asset retirement obligations is calculated using a discounted cash flow model. During the three and nine months ended September 30, 2015 , the Company recognized impairment charges of $63.4 million and $74.2 million, respectively. The impairment charges include the write off of $5.3 million and $12.0 million in carrying value of decommissioned towers , a $56.7 million impairment charge recorded in the third quarter of 2015 related to fiber assets acquired in the 2012 Mobilitie transaction, and $1.4 million and $4.3 million of other third party decommission costs incurred related to the Company’s long-lived assets and intangibles for the three and nine months ended September 30, 2015 , respectively . The impairment review of the fiber assets was triggered by a strategic decision made by the Company during the third quarter. The undiscounted cash flows were not sufficient to recover the carrying amount of the assets and thus a discounted cash flow valuation was use d to determine the fair value. Key assumptions used in the valuation include forecasts of revenue and expenses o ver an extended period of time, and estimated costs of debt and equity capital to discount the projected cash flows. Certain of these assumptions involve significant judgment, are based on management’s estimate of current and forecasted market conditions and are sensitive and susceptible to change. In addition, for the nine months ended September 30, 2015, the impairment charge includes $ 1.2 million in exit costs related to the Company’s former corporate headquarters building. During the three and nine months ended September 30, 2014 , the Company recognized impairment charges of $6.0 million and $13.6 million, respectively. The impairment charges include the write off of $4.7 million and $10.0 million in carrying value of decommissioned towers and $1.3 million and $3.6 million of other third party decommission costs incurred related to the Company’s long-lived assets and intangibles for the three and nine months ended September 30, 2014 , respectively. These write offs result from the Company’s analysis that the future cash flows from certain asset s would not recover the carrying value of the investment in those asset s . Asset impairment and decommission costs and the related impaired assets relate to the Company’s site leasing operating segment. Fair Value of Financial Instruments — The carrying values of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, and short-term investments approximate their estimated fair values due to the short maturity of these instruments. Short-term investments consisted of $0.5 million and $5.3 million in certificate of deposits, as of September 30, 2015 and December 31, 2014 , respectively , and $0.2 million in Treasury securities as of September 30, 2015 and December 31, 2014 . The Company’s estimate of the fair value of its held-to-maturity investments in treasury and corporate bonds, including current portion, are based primarily upon Level 1 reported market values. As of September 30, 2015 and December 31, 2014 , the carrying value and fair value of the held-to-maturity investments, including current portion, were $1.0 million and $1.1 million, respectively. The Company determines the fair value of its debt instruments utilizing various Level 2 sources including quoted prices and indicative quotes (non-binding quotes) from brokers that require judgment to interpret market information including implied credit spreads for similar borrowings on recent trades or bid/ask prices. The fair value of the Revolving Credit Facility is considered to approximate the carrying value because the interest payments are based on Eurodollar rates that reset every month. The Company does not believe its credit risk has changed materially from the date the applicable Eurodollar Rate plus 137.5 to 200.0 basis points was set for the Revolving Credit Facility. Refer to Note 10 for the fair values, principal balances, and carrying values of the Company’s debt instruments.

Restricted Cash [Abstract]
Restricted Cash	3. RESTRICTED CASH Restricted cash consists of the following: As of As of September 30, 2015 December 31, 2014 Included on Balance Sheet (in thousands) Securitization escrow accounts $ $ Restricted cash - current asset Payment and performance bonds Restricted cash - current asset Surety bonds and workers compensation Other assets - noncurrent Total restricted cash $ $ Pursuant to the terms of the Tower Securities (see Note 10), the Company is required to establish a securitization escrow account, held by an indenture trustee, into which all rents and other sums due on the towers that secure the Tower Securities are directly deposited by the lessees. These restricted cash amounts are used to fund reserve accounts for the payment of (1) debt service costs, (2) ground rents, real estate and personal property taxes and insurance premiums related to towers, (3) trustee and servicing expenses, and (4) management fees and to reserve a portion of advance rents from tenants. The restricted cash in the securitization escrow account in excess of required reserve balances is subsequently released to the Borrowers (as defined in Note 10) monthly, provided that the Borrowers are in compliance with their debt service coverage ratio and that no event of default has occurred. All monies held by the indenture trustee are classified as Restricted cash on the Company’s Consolidated Balance Sheets. Payment and performance bonds relate primarily to collateral requirements for tower construction currently in process by the Company. Cash is pledged as collateral related to surety bonds issued for the benefit of the Company or its affiliates in the ordinary course of business and primarily relates to the Company’s tower removal obligations. As of September 30, 2015 and December 31, 2014 , the Company had $38.0 million and $38.3 million in surety bonds and payment and performance bonds, respectively, for which it was only required to post $0.8 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum requirements. As of September 30, 2015 and December 31, 2014 , the Company had also pledged $2.5 million and $2.6 million, respectively, as collateral related to its workers compensation policy.

Acquisitions [Abstract]
Acquisitions	5. ACQUISITIONS The Company acquired 225 communication sites during the three months ended September 30, 2015 .

Income Taxes	13. INCOME TAXES The primary reason for the difference in the Company’s effective tax rate and the US statutory rate is a result of the Company having a full valuation allowance on its US net deferred tax assets. The Company has concluded that it is not more likely than not that its deferred tax assets will be realized and has recorded a full valuation allowance. A foreign tax provision is recognized because certain international subsidiaries of the Company have profitable operations or are in a net deferred tax liability position.

Foreign Currency Translation	Foreign Currency Translation All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency (Brazil and Canada) are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the period.

Intercompany Loans	Intercompany Loans In accordance with Accounting Standards Codification (ASC) 830, the Company remeasures intercompany loans not denominated in the functional currency with the corresponding remeasurement adjustment being recorded in Other income (expense), net in the Consolidated Statements of Operations. For the three and nine months ended September 30, 2015 , the Company recorded a $112.1 million and $180.4 million foreign exchange loss, respectively, on the remeasurement of an intercompany loan with a Brazilian subsidiary.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board ("FASB") released updated guidance regarding the recognition of revenue from contracts with customers, exclusive of those contracts within lease accounting. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contracts with the customer; (2) identify the performance obligations in the contract; (3) determine the contract price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The new guidance is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 for public companies. Under the proposal, the standard would be required to be adopted by public business entities in annual periods beginning on or after December 15, 2017. Early adoption is permitted but not before interim and annual reporting periods beginning after December 15, 2016. This guidance is required to be applied (1) retrospectively to each prior reporting period presented, or (2) with the cumulative effect being recognized at the date of initial application. The Company is evaluating the guidance including the impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest. The standard requires debt issuance costs to be presented on the balance sheet as a direct deduction from the related debt liability rather than as an asset. Once adopted, entities are required to apply the new guidance retrospectively to all prior periods presented. ASU 2015-03 is effective for annual and interim periods beginning after December 15, 2015 and early application is permitted. The Company has not elected to early adopt the standard. In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest - Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. The standard indicates the SEC staff would not object to presenting deferred debt issuance costs for a line of credit arrangement as an asset in the balance sheet. ASU 2015-15 is effective for annual and interim periods beginning after December 15, 2015 and early application is permitted. The Company has not elected to early adopt the standard. In September 2015, the FASB issued ASU 2015-16 Business Combinations. The standard requires that the acquirer (1) recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, (2) record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date, and (3) to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for annual and interim periods beginning after December 15, 2015 and early application is permitted. The Company has not elect ed to early adopt the standard.
