Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Organization and Basis of Presentation Organization Liberty Property Trust (the “Trust”) is a self-administered and self-managed Maryland real estate investment trust (a “REIT”). Substantially all of the Trust’s assets are owned directly or indirectly, and substantially all of the Trust’s operations are conducted directly or indirectly, by its subsidiary, Liberty Property Limited Partnership, a Pennsylvania limited partnership (the “Operating Partnership” and, together with the Trust and their consolidated subsidiaries, the “Company”). The Trust is the sole general partner and also a limited partner of the Operating Partnership, owning 97.7% of the common equity of the Operating Partnership at September 30, 2017 . The Company owns and operates industrial properties nationally and owns and operates office properties in a focused group of office markets. Additionally, the Company owns certain assets in the United Kingdom. Unless otherwise indicated, the notes to the Consolidated Financial Statements apply to both the Trust and the Operating Partnership. The terms the “Company,” “we,” “our” and “us” mean the Trust and Operating Partnership collectively. The Operating Partnership is a variable interest entity ("VIE") of the Trust as the limited partners do not have substantive kick-out or participating rights. The Trust is the primary beneficiary of the Operating Partnership as it has the power to direct the activities of the Operating Partnership and the rights to absorb 97.7% of the net income of the Operating Partnership. The Trust has no significant assets or liabilities other than its investment in the Operating Partnership. As the Operating Partnership is already consolidated in the balance sheets of the Trust, the identification of this entity as a VIE has no impact on the consolidated financial statements of the Trust. In addition, the Company holds a 20% interest in Liberty/Comcast 1701 JFK Boulevard, LP which was determined to be a VIE. The Company determined that it is not the primary beneficiary as the Company and its third party partner share control of the joint venture. The Company's maximum exposure to loss is equal to its equity investment in the joint venture which was $17.6 million and $18.7 million as of September 30, 2017 and December 31, 2016, respectively. Basis of Presentation The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“US GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K of the Company for the year ended December 31, 2016 . In the opinion of management, all adjustments (consisting solely of normal recurring adjustments) necessary for a fair presentation of the financial statements for these interim periods have been included. The results of interim periods are not necessarily indicative of the results to be obtained for a full fiscal year. In the fourth quarter of 2016, the Company entered into an agreement relating to the development, for a fee, of an office building at its Camden Waterfront project in Camden, NJ. Project revenues and related costs and expenses are presented on a gross basis as "Development service fee income" and "Development service fee expense" in the Consolidated Statements of Comprehensive Income. Additionally, at the same time, the Company began classifying development fees and expenses relating to its development fee arrangements for certain unconsolidated joint venture projects in a manner consistent with the Camden project described above. Previously, development service fee income relating to its unconsolidated joint ventures had been classified as other income and development service fee expense had been classified as general and administrative expense in amounts as follows: Three months ended Nine months ended September 30, 2016 September 30, 2016 Other income $ 1,219 $ 3,789 General and administrative $ 1,058 $ 3,210 In the first quarter of 2017, the Company adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which requires the Company to reclassify shares withheld for tax withholding purposes on share-based compensation awards from operating activities to financing activities. As a result of the adoption, a $4.8 million cash outflow has been reclassified in the September 30, 2016 consolidated statement of cash flows from operating activities to financing activities. In the third quarter of 2017, the Company began to separately classify expensed pursuit costs (see Note 7) in the Consolidated Statements of Comprehensive Income. These costs, which were reclassed retrospectively for all periods, were formerly classified as general and administrative expense. Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which supersedes nearly all existing revenue recognition guidance (except revenue in the scope of other accounting standards, including standards related to leasing). Subsequently, the FASB issued the following standards related to ASU 2014-09: ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations; ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ; ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ; and ASU 2017-13, Revenue from Contracts with Customers (Topic 606): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments (collectively, the “New Revenue Standards”). The Company must adopt the New Revenue Standards effective January 1, 2018. The New Revenue Standards clarify the required factors that an entity must consider when recognizing revenue and require additional disclosures concerning contracts with customers, judgments concerning revenue recognition, and assets recognized for the costs to obtain or fulfill a contract. The Company continues to evaluate the New Revenue Standards by analyzing certain revenue streams. The Company concluded that there are no revenue streams from its lease agreements that are covered by the New Revenue Standards with the exception of non-lease components as further discussed. Once the new guidance setting forth principles for the recognition, measurement, presentation and disclosure of leases goes into effect on January 1, 2019, the Company believes that the New Revenue Standards will apply to components of revenue due under leases that are deemed to be non-lease components (such as common area maintenance and provision of utilities), which could affect the recognition pattern for such revenue. The Company continues to evaluate the qualitative and quantitative disclosure requirements of the New Revenue Standards. The Company does not expect the New Revenue Standards to have a material impact on the measurement and recognition of gains and losses on the sale of properties. The Company is in the process of evaluating any impact on the amount and timing of recognizing its development service fee income, which is currently accounted for under the percentage of completion method based on applicable costs incurred and estimated to be incurred. The Company continues to assess the impact from adopting the New Revenue Standards on its business processes, financial reporting disclosures, and internal controls over financial reporting (“ICFR”). Significant assessment and implementation matters to be addressed prior to adopting the New Revenue Standards include completing a review of certain customer contracts, determining the impact the new accounting standard will have on the Company’s financial statements and related disclosures, and updating, through the completion of the implementation, the Company’s business processes, systems, and controls required to comply with the New Revenue Standards. Upon completion of the Company’s implementation plan and evaluation of the remaining revenue contracts, the Company will adopt additional controls around ICFR and its business processes for any new and existing revenue arrangements. The Company is on target to complete its assessment of the New Revenue Standards and the impact on the Company’s financial statements and related disclosures as of January 1, 2018. Although the Company is still completing its analysis of the impact from adopting the New Revenue Standards, the Company does not anticipate the impact to be material and, as a result, the Company plans to adopt the New Revenue Standards using the modified retrospective method. In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 is effective for the Company beginning January 1, 2019. Early adoption of ASU 2016-02 is permitted. The standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. For leases in which the Company is the lessor, the standard requires that the lease and non-lease components of the lease agreement should be separated. Revenue related to the lease component of the contract will be recognized on a straight-line basis, while revenue related to the non-lease component will be recognized under the provisions of the New Revenue Standards. For lease agreements longer than one year in which the Company is the lessee, the Company will measure the present value of the future lease payments and recognize a right-of-use asset and corresponding lease liability on its balance sheet. In addition, the new standard states that only direct leasing costs may be capitalized. The Company is evaluating the impact ASU 2016-02 will have on its financial position and results of operations. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 is designed to clarify how entities should classify cash receipts and cash payments in the statement of cash flows. ASU 2016-15 is effective for the Company beginning January 1, 2018. Early adoption of ASU 2016-15 is permitted. The standard requires retrospective application unless it is impracticable to do so. The Company is evaluating the impact ASU 2016-15 will have on its statement of cash flows. In February 2017, the FASB issued ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets ("ASU 2017-05"). ASU 2017-05 is designed to provide guidance on how to recognize gain and losses on sales, including partial sale, of nonfinancial assets to noncustomers. ASU 2017-05 is effective for the Company beginning January 1, 2018. Early adoption is permitted but the standard is required to be adopted concurrently with the New Revenue Standards. The Company is evaluating the impact ASU 2017-05 will have on the Company's financial position and results of operations. In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting ("ASU 2017-09"). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 is effective for the Company beginning January 1, 2018. Early adoption is permitted. The new guidance will be applied prospectively to awards modified on or after the adoption date. The Company is evaluating the impact ASU 2017-09 will have on the Company's financial position and results of operations. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"). ASU 2017-12 is designed to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 is effective for the Company beginning January 1, 2019. Early adoption is permitted using a modified retrospective transition method. This adoption method will require the Company to recognize the cumulative effect of initially applying ASU 2017-12 as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. The Company is evaluating the impact ASU 2017-12 will have on the Company's financial position and results of operations. |

Segment Reporting [Abstract] | |
Segment Information | Segment Information The Company owns and operates industrial properties nationally and owns and operates office properties in a focused group of office markets. Additionally, the Company owns certain assets in the United Kingdom. During the nine months ended September 30, 2017, the Company realigned its reportable segments as follows: • Carolinas/Richmond; • Chicago/Minneapolis; • Florida; • Houston; • Lehigh/Central PA; • Philadelphia; • Southeastern PA; and • United Kingdom. Certain other segments are aggregated into an "Other" category which includes the reportable segments: Arizona; Atlanta; Cincinnati/Columbus/Indianapolis; Dallas; DC Metro; New Jersey; and Southern California. Comparative prior periods have been restated to reflect current segment disclosures. The Company evaluates the performance of its reportable segments based on segment net operating income (“SNOI”). SNOI is defined as net operating income (rental revenue and operating expense reimbursements less rental property and real estate tax expenses) less amortization of lease transaction costs and other operating expenses which relate directly to the management and operation of the assets within each reportable segment. The Company's accounting policies for the segments are the same as those used in the Company's consolidated financial statements. There are no material inter-segment transactions. The operating information by reportable segment is as follows (in thousands): Three Months Nine Months Ended September 30, Ended September 30, 2017 2016 2017 2016 Operating revenue Carolinas/Richmond $ 18,910 $ 17,292 $ 55,192 $ 49,226 Chicago/Minneapolis 16,147 23,417 47,789 66,848 Florida 15,072 28,115 43,802 85,230 Houston 15,167 14,870 44,720 43,840 Lehigh/Central PA 40,698 34,157 122,048 102,182 Philadelphia 11,137 10,513 33,501 31,253 Southeastern PA 15,422 24,563 45,165 74,789 United Kingdom 3,773 3,275 10,204 10,352 Other 33,288 34,831 95,826 104,274 Segment-level operating revenue 169,614 191,033 498,247 567,994 Reconciliation to total operating revenues Development service fee income 24,176 — 53,920 — Other (137 ) (176 ) (18 ) (341 ) Total operating revenue $ 193,653 $ 190,857 $ 552,149 $ 567,653 SNOI Carolinas/Richmond $ 13,621 $ 12,198 $ 39,698 $ 34,257 Chicago/Minneapolis 9,554 12,519 28,913 35,761 Florida 10,176 18,340 29,686 53,129 Houston 8,701 7,989 23,263 24,858 Lehigh/Central PA 29,995 24,982 88,656 73,939 Philadelphia 8,743 7,750 25,987 23,089 Southeastern PA 9,246 16,244 25,866 44,544 United Kingdom 1,781 2,031 5,288 6,871 Other 21,901 23,201 64,089 68,980 SNOI 113,718 125,254 331,446 365,428 Reconciliation to net income Interest expense (23,060 ) (29,528 ) (67,345 ) (91,071 ) Loss on debt extinguishment — (3,494 ) — (3,494 ) Depreciation/amortization expense (1) (33,521 ) (34,896 ) (99,829 ) (113,855 ) Impairment charges - real estate assets (9,650 ) — (9,650 ) — Gain on property dispositions 23,840 1,318 30,542 25,671 Equity in earnings of unconsolidated joint ventures 4,305 9,043 14,026 19,540 General and administrative expense (1) (8,104 ) (10,406 ) (31,230 ) (33,910 ) Expensed pursuit costs (4,772 ) (772 ) (4,957 ) (882 ) Income taxes (1) (64 ) 17 (240 ) (1,203 ) Other (1,533 ) (802 ) (4,542 ) (370 ) Net income $ 61,159 $ 55,734 $ 158,221 $ 165,854 (1) Excludes costs which are included in determining SNOI.

Asset Impairment Charges [Text Block] | Accounting for the Impairment of Long-Lived Assets and Fee Development Contracts Impairment Charges - Real Estate Assets The Company disposes of and anticipates the potential disposition of certain properties prior to the end of their remaining useful lives. During the three and nine months ended September 30, 2017 the Company recognized $9.7 million in impairment charges which related to the Company's Houston reportable segment. There were no impairment charges recognized during the three or nine months ended September 30, 2016. The Company determined these impairments based on third party offer prices and quoted offer prices for comparable transactions which are Level 2 and Level 3 inputs, respectively, according to the fair value hierarchy established in ASC 820. These measurements have occurred as circumstances arise, and the resulting estimates of fair value are not necessarily reflective of measurements at the period’s end. The Company has applied reasonable additional estimates and judgments in evaluating each of its properties and land held for development and has determined that there were no additional valuation adjustments necessary at September 30, 2017 . Should external or internal circumstances change requiring the need to shorten the holding periods or adjust the estimated future cash flows of the Company’s assets, the Company could be required to record impairment charges in the future. Fee Development Contracts From time to time, the Company enters into contracts to develop properties on a fee basis for joint ventures in which the Company holds an interest or for unrelated third parties. In these cases the Company typically agrees to be responsible for all aspects of the development of the project (and, in certain instances, related infrastructure) and to guarantee the timely lien-free completion of construction of the project and the payment, subject to certain exceptions, of cost overruns incurred in the development of the project. If the Company encounters construction delays or unexpected costs in the development of these projects or is otherwise unable to recover the costs it incurs, the resulting unrecovered costs and potential payments to customers could generate losses that would adversely affect the Company's cash flow and net income. On a quarterly basis, the Company applies reasonable estimates and judgments to assess whether or not it is necessary to accrue any estimated future losses with respect to such contracts. There were no such losses recognized during the three or nine months ended September 30, 2017 or 2016. Should external or internal circumstances change requiring the Company to adjust the estimated future cash flows from these development contracts or that suggest that such development contracts may result in a loss, the Company could be required to record losses in the future. Expensed Pursuit Costs The Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable. Future development is dependent upon various factors, including zoning and regulatory approval, rental market conditions and construction costs. Initial pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a future development by the Company is no longer probable, any capitalized pre-development costs are written off with a charge to expense. The Company expensed costs related to pursuit costs of $4.8 million and $5.0 million for the three and nine months ended September 30, 2017 and $772,000 and $882,000 for the three and nine months ended September 30, 2016. These costs are included in expensed pursuit costs on the accompanying Consolidated Statements of Comprehensive Income. |

Debt Instrument, Fair Value Disclosure [Abstract] | |
Disclosure of Fair Value of Financial Instruments | Fair Value of Financial Instruments ASC 820, Fair Value Measurements and Disclosures, provides guidance on the fair value measurement of a financial asset or liability. Inputs used to develop fair value are classified in one of three categories: Level 1 inputs (quoted prices (unadjusted) in active markets for identical assets or liabilities), Level 2 inputs (inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly) and Level 3 inputs (unobservable inputs for the asset or liability). The following disclosure of estimated fair value was determined by management using available market information and appropriate valuation methodologies. However, considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the following estimates are not necessarily indicative of the amounts the Company could have realized on disposition of the financial instruments at September 30, 2017 and December 31, 2016 . The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued interest, dividend and distributions payable and other liabilities are reasonable estimates of fair value because of the short-term nature of these instruments. The carrying value of the outstanding amounts under the Company's credit facility is a reasonable estimate of fair value because interest rates float at a rate based on LIBOR. The Company determines the fair value of its interest rate swaps by using the standard methodology of netting discounted future fixed cash payments with the discounted expected variable cash receipts. These variable cash receipts of interest rate swaps are based on expectations of future LIBOR interest rates (forward curves) estimated by observing market LIBOR interest rate curves. This is a Level 2 fair value calculation. Also, credit valuation adjustments are factored into the fair value calculations to account for potential nonperformance risk. These credit valuation adjustments were concluded to be not significant inputs for the fair value calculations for the periods presented. See Note 13 - Derivative Instruments. The Company used a discounted cash flow model to determine the estimated fair value of its debt as of September 30, 2017 and December 31, 2016 . This is a Level 3 fair value calculation. The inputs used in preparing the discounted cash flow model include actual maturity dates and scheduled cash flows as well as estimates for market value discount rates. The Company updates the discounted cash flow model on a quarterly basis to reflect any changes in the Company's debt holdings and changes to discount rate assumptions. The following summarizes the fair value of the Company's mortgage loans and unsecured notes as of December 31, 2016 and September 30, 2017 (in thousands): Mortgage Loans Unsecured Notes Carrying Value Fair Value Carrying Value Fair Value As of December 31, 2016 $ 276,650 $ 286,684 $ 2,280,286 $ 2,340,762 As of September 30, 2017 $ 269,380 $ 281,671 $ 2,282,828 $ 2,379,014 |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Interest rate swaps [Text Block] | Derivative Instruments The Company borrows funds at a combination of fixed and variable rates. Borrowings under the Company's revolving credit facility and certain bank mortgage loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. The Company's interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and to lower the Company's overall borrowing costs. To achieve these objectives, from time to time, the Company enters into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. The Company generally does not hold or issue these derivative contracts for trading or speculative purposes. Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive loss (for the Trust) and general partner's equity and limited partners ’ equity - common units (for the Operating Partnership) and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings. The Company determines the fair value of its interest rate swaps by using the standard methodology of netting discounted future fixed cash payments with the discounted expected variable cash receipts. These variable cash receipts of interest rate swaps are based on expectations of future LIBOR interest rates (forward curves) estimated by observing market LIBOR interest rate curves. This is a Level 2 fair value calculation. Also, credit valuation adjustments are factored into the fair value calculations to account for potential nonperformance risk. These credit valuation adjustments were concluded to be not significant inputs for the fair value calculations for the periods presented. The Company holds an interest in three interest rate swap contracts (“Swaps”) that eliminate the impact of changes in interest rates on the payments required under variable rate mortgages. The Swaps had aggregate notional amounts of $96.9 million and $98.9 million at September 30, 2017 and December 31, 2016 , respectively, and expire at various dates between 2018 and 2020 . The Company accounts for the effective portion of changes in the fair value of a derivative in accumulated other comprehensive loss and subsequently reclassifies the effective portion to earnings over the term that the hedged transaction affects earnings. The Company accounts for the ineffective portion of changes in the fair value of a derivative directly in earnings. The following table presents the location in the financial statements of the gains or losses recognized related to the Company’s cash flow hedges for the three and nine months ended September 30, 2017 and 2016 (in thousands): Three Months Ended Nine Months Ended September 30, 2017 September 30, 2016 September 30, 2017 September 30, 2016 Amount of gain (loss) related to the effective portion recognized in other comprehensive income (loss) $ 19 $ 415 $ (7 ) $ (1,928 ) Amount of loss related to the effective portion subsequently reclassified to interest expense $ (75 ) $ (264 ) $ (391 ) $ (823 ) Amount of (loss) gain related to the ineffective portion recognized in interest expense $ (8 ) $ 7 $ 5 $ (71 ) The fair value of the Swaps in the amounts of $3.1 million and $4.9 million as of September 30, 2017 and December 31, 2016 , respectively, is included in other liabilities in the accompanying consolidated balance sheets. The Company estimates that $0.2 million will be reclassified from accumulated other comprehensive loss as an increase to interest expense over the next 12 months. The Company has agreements with its derivative counterparties that contain a provision whereby if the Company defaults on any of its indebtedness, including defaults where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. If the Company were to breach any of the contractual provisions of the derivative contracts, it would be required to settle its obligations under the agreements at their termination value including accrued interest, which totaled approximately $3.1 million as of September 30, 2017 . |

The Environmental Assessments did not reveal, nor is the Company aware of, any non-compliance with environmental laws, environmental liability or other environmental claim that the Company believes would likely have a material adverse effect on the Company. Operating Ground Lease Agreements Future minimum rental payments under the terms of all non-cancelable operating ground leases under which the Company is the lessee, as of September 30, 2017 , were as follows (in thousands): Year Amount 2017 (remaining) $ 443 2018 1,767 2019 1,767 2020 1,767 2021 1,767 2022 and thereafter 34,905 Total $ 42,416 Operating ground lease expense for the three and nine months ended September 30, 2017 was $313,000 and $936,000 , respectively, as compared to $241,000 and $734,000 , respectively, for the same periods in 2016 . Legal Matters From time to time, the Company is a party to a variety of legal proceedings, claims and assessments arising in the normal course of business. As of September 30, 2017 there were no legal proceedings, claims or assessments that the Company expects to have a material adverse effect on the Company’s business or financial statements. Other As of September 30, 2017 , the Company had letter of credit obligations of $6.3 million . As of September 30, 2017 , the Company had 24 buildings under development. These buildings are expected to contain, when completed, a total of 5.9 million square feet of leasable space and represent an anticipated aggregate investment of $560.8 million . At September 30, 2017 , development in progress totaled $395.1 million . In addition, as of September 30, 2017 , the Company had invested $14.4 million in deferred leasing costs related to these development buildings. As of September 30, 2017 , the Company was committed to $8.3 million in improvements on certain buildings and land parcels. As of September 30, 2017 , the Company was committed to $35.6 million in future land acquisitions. The Company expects to complete these purchases during the year ended December 31, 2017. As of September 30, 2017 , the Company was obligated to pay for tenant improvements not yet completed for a maximum of $26.7 million . Unconsolidated joint ventures in which the Company holds an interest, and in another case an unrelated third party, have engaged the Company as the developer of certain development properties pursuant to development agreements. The Company agrees, in consideration for a development fee, to be responsible for all aspects of the development of the properties (and, in certain instances, related infrastructure) and to guarantee the timely lien-free completion of construction of the properties and the payment, subject to certain exceptions, of any cost overruns incurred in the development of the properties. The Company is currently developing four properties for its unconsolidated joint ventures which represent an anticipated aggregate investment by the joint ventures of $976.9 million . As of September 30, 2017 , the Company was also committed to approximately $170.1 million in costs related to its agreement to develop, on a fee basis, an office building and infrastructure improvements for American Water Works in Camden, New Jersey. As of September 30, 2017 , $71.8 million of these costs had been incurred. The Company maintains cash and cash equivalents at financial institutions. The combined account balances at each institution typically exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company believes the risk is not significant. |

Supplemental Cash Flow Information [Abstract] | |
Supplemental Disclosure to Statements of Cash Flows | Supplemental Disclosure to Consolidated Statements of Cash Flows The following are supplemental disclosures to the consolidated statements of cash flows for the nine months ended September 30, 2017 and 2016 (amounts in thousands): 2017 2016 Write-off of fully depreciated/amortized property and deferred costs $ 26,609 $ 26,349 Write-off of depreciated/amortized property and deferred costs due to sale $ 13,127 $ 34,513 Write-off of costs related to early debt extinguishment $ — $ 109 Redemption of noncontrolling interests - common units $ 27 $ 132 Unrealized gain (loss) on cash flow hedge $ 366 $ (1,132 ) Changes in accrued development capital expenditures $ 18,255 $ (7,522 ) Capitalized equity-based compensation $ 877 $ 980 Amounts paid in cash for deferred leasing costs incurred in connection with signed leases with tenants are paid in conjunction with improving (acquiring) property, plant and equipment. Such costs are not contained within net real estate. However, they are integral to the completion of a tenant lease and ultimately are related to the improvement and thus the value of the Company’s property, plant and equipment. They are therefore included in investing activities in the Company’s consolidated statements of cash flows. |

Subsequent Event [Line Items] | |
Subsequent Events [Text Block] | Subsequent Events Credit Facility In October 2017, the Company replaced its existing $800 million credit facility which was set to mature in March 2018 with a new $900 million unsecured credit facility. The new facility includes a revolving credit facility for aggregate borrowings up to $800 million (the "Revolving Credit Facility") and a delayed draw term loan facility aggregating up to $100 million . It matures in October 2021 and the Company has options to extend the maturity date for up to one additional year. Based upon the Company’s current credit ratings, borrowings under the Revolving Credit Facility bear interest at LIBOR plus 87.5 basis points and bear interest at LIBOR plus 95 basis points for delayed draw term loans. There is also a 15 basis point annual facility fee. The Revolving Credit Facility contains a competitive bid option, whereby participating lenders bid on the interest rate to be charged. This feature is available for up to 50% of the amount of the Revolving Credit Facility. The financial and other covenants under the new facility are similar to our previous credit facility. The Company expects to incur approximately $5.1 million of debt issuance costs associated with the new facility. Agreement of Sale On October 2, 2017 the Company entered into an agreement to sell 14 office properties totaling 641,000 square feet of leasable space for $75.4 million . The properties are in the Southeastern PA segment. The sale is currently anticipated to close in 2017, subject to the satisfaction of certain closing conditions. |

New Accounting Pronouncements, Policy [Policy Text Block] | Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which supersedes nearly all existing revenue recognition guidance (except revenue in the scope of other accounting standards, including standards related to leasing). Subsequently, the FASB issued the following standards related to ASU 2014-09: ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations; ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ; ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ; and ASU 2017-13, Revenue from Contracts with Customers (Topic 606): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments (collectively, the “New Revenue Standards”). The Company must adopt the New Revenue Standards effective January 1, 2018. The New Revenue Standards clarify the required factors that an entity must consider when recognizing revenue and require additional disclosures concerning contracts with customers, judgments concerning revenue recognition, and assets recognized for the costs to obtain or fulfill a contract. The Company continues to evaluate the New Revenue Standards by analyzing certain revenue streams. The Company concluded that there are no revenue streams from its lease agreements that are covered by the New Revenue Standards with the exception of non-lease components as further discussed. Once the new guidance setting forth principles for the recognition, measurement, presentation and disclosure of leases goes into effect on January 1, 2019, the Company believes that the New Revenue Standards will apply to components of revenue due under leases that are deemed to be non-lease components (such as common area maintenance and provision of utilities), which could affect the recognition pattern for such revenue. The Company continues to evaluate the qualitative and quantitative disclosure requirements of the New Revenue Standards. The Company does not expect the New Revenue Standards to have a material impact on the measurement and recognition of gains and losses on the sale of properties. The Company is in the process of evaluating any impact on the amount and timing of recognizing its development service fee income, which is currently accounted for under the percentage of completion method based on applicable costs incurred and estimated to be incurred. The Company continues to assess the impact from adopting the New Revenue Standards on its business processes, financial reporting disclosures, and internal controls over financial reporting (“ICFR”). Significant assessment and implementation matters to be addressed prior to adopting the New Revenue Standards include completing a review of certain customer contracts, determining the impact the new accounting standard will have on the Company’s financial statements and related disclosures, and updating, through the completion of the implementation, the Company’s business processes, systems, and controls required to comply with the New Revenue Standards. Upon completion of the Company’s implementation plan and evaluation of the remaining revenue contracts, the Company will adopt additional controls around ICFR and its business processes for any new and existing revenue arrangements. The Company is on target to complete its assessment of the New Revenue Standards and the impact on the Company’s financial statements and related disclosures as of January 1, 2018. Although the Company is still completing its analysis of the impact from adopting the New Revenue Standards, the Company does not anticipate the impact to be material and, as a result, the Company plans to adopt the New Revenue Standards using the modified retrospective method. In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 is effective for the Company beginning January 1, 2019. Early adoption of ASU 2016-02 is permitted. The standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. For leases in which the Company is the lessor, the standard requires that the lease and non-lease components of the lease agreement should be separated. Revenue related to the lease component of the contract will be recognized on a straight-line basis, while revenue related to the non-lease component will be recognized under the provisions of the New Revenue Standards. For lease agreements longer than one year in which the Company is the lessee, the Company will measure the present value of the future lease payments and recognize a right-of-use asset and corresponding lease liability on its balance sheet. In addition, the new standard states that only direct leasing costs may be capitalized. The Company is evaluating the impact ASU 2016-02 will have on its financial position and results of operations. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 is designed to clarify how entities should classify cash receipts and cash payments in the statement of cash flows. ASU 2016-15 is effective for the Company beginning January 1, 2018. Early adoption of ASU 2016-15 is permitted. The standard requires retrospective application unless it is impracticable to do so. The Company is evaluating the impact ASU 2016-15 will have on its statement of cash flows. In February 2017, the FASB issued ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets ("ASU 2017-05"). ASU 2017-05 is designed to provide guidance on how to recognize gain and losses on sales, including partial sale, of nonfinancial assets to noncustomers. ASU 2017-05 is effective for the Company beginning January 1, 2018. Early adoption is permitted but the standard is required to be adopted concurrently with the New Revenue Standards. The Company is evaluating the impact ASU 2017-05 will have on the Company's financial position and results of operations. In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting ("ASU 2017-09"). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 is effective for the Company beginning January 1, 2018. Early adoption is permitted. The new guidance will be applied prospectively to awards modified on or after the adoption date. The Company is evaluating the impact ASU 2017-09 will have on the Company's financial position and results of operations. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"). ASU 2017-12 is designed to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 is effective for the Company beginning January 1, 2019. Early adoption is permitted using a modified retrospective transition method. This adoption method will require the Company to recognize the cumulative effect of initially applying ASU 2017-12 as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. The Company is evaluating the impact ASU 2017-12 will have on the Company's financial position and results of operations. |

Segment Reporting [Abstract] | |
Segment Reporting, Policy [Policy Text Block] | The Company evaluates the performance of its reportable segments based on segment net operating income (“SNOI”). SNOI is defined as net operating income (rental revenue and operating expense reimbursements less rental property and real estate tax expenses) less amortization of lease transaction costs and other operating expenses which relate directly to the management and operation of the assets within each reportable segment. |

Fair Value Disclosures [Abstract] | |
Fair Value of Financial Instruments, Policy [Policy Text Block] | ASC 820, Fair Value Measurements and Disclosures, provides guidance on the fair value measurement of a financial asset or liability. Inputs used to develop fair value are classified in one of three categories: Level 1 inputs (quoted prices (unadjusted) in active markets for identical assets or liabilities), Level 2 inputs (inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly) and Level 3 inputs (unobservable inputs for the asset or liability). The following disclosure of estimated fair value was determined by management using available market information and appropriate valuation methodologies. However, considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the following estimates are not necessarily indicative of the amounts the Company could have realized on disposition of the financial instruments at September 30, 2017 and December 31, 2016 . The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued interest, dividend and distributions payable and other liabilities are reasonable estimates of fair value because of the short-term nature of these instruments. The carrying value of the outstanding amounts under the Company's credit facility is a reasonable estimate of fair value because interest rates float at a rate based on LIBOR. The Company determines the fair value of its interest rate swaps by using the standard methodology of netting discounted future fixed cash payments with the discounted expected variable cash receipts. These variable cash receipts of interest rate swaps are based on expectations of future LIBOR interest rates (forward curves) estimated by observing market LIBOR interest rate curves. This is a Level 2 fair value calculation. Also, credit valuation adjustments are factored into the fair value calculations to account for potential nonperformance risk. These credit valuation adjustments were concluded to be not significant inputs for the fair value calculations for the periods presented. See Note 13 - Derivative Instruments. The Company used a discounted cash flow model to determine the estimated fair value of its debt as of September 30, 2017 and December 31, 2016 . This is a Level 3 fair value calculation. The inputs used in preparing the discounted cash flow model include actual maturity dates and scheduled cash flows as well as estimates for market value discount rates. The Company updates the discounted cash flow model on a quarterly basis to reflect any changes in the Company's debt holdings and changes to discount rate assumptions. |
