Philadelphia's Department of Aviation has closed on a $42 million deal for a vacant five-story office building just southwest of Philadelphia International Airport, adding a 441,000-square-foot property to its landside holdings without touching a dime of city tax revenue. The building at 8800 Tinicum Blvd had sat empty since PNC Bank moved out in early 2024, and its sale marks the last property Office Properties Income Trust owned in the Philadelphia market.
The purchase price works out to roughly $95.24 per square foot, according to CoStar, which reported that the Department of Aviation acquired the building directly from Office Properties Income Trust, a real estate investment trust externally managed by The RMR Group. The site sits about 1.4 miles from PHL and directly along Interstate 95, giving it what Avison Young has described as strong highway connectivity to regional logistics networks and maritime ports.
City records show the deal moved through a formal legislative process well before closing. Philadelphia City Council passed Ordinance File No. 260416 in April 2026, authorizing the Director of the Department of Aviation to acquire fee simple title to the property, following a recommendation Mayor Cherelle L. Parker submitted to the City Council on April 28, 2026.
A Building That Never Found Its Next Use
The tower's vacancy wasn't for lack of trying to reposition it. In April 2025, Office Properties Income Trust had announced plans with Avison Young to convert the site into a 477,500-square-foot industrial air-cargo and distribution facility, aiming to capture regional e-commerce demand, but that redevelopment never broke ground before the property changed hands. Avison Young principal Jim Scott served as the seller's exclusive broker on the eventual $42 million sale, according to Bisnow's report on the transaction.
Office Properties Income Trust's decision to offload its final Philadelphia asset came amid a broader financial reset. The REIT completed a Chapter 11 bankruptcy restructuring in June 2026 that wiped out $714 million in debt, and Bisnow reported that the July 30 sale fits into an aggressive post-bankruptcy push to liquidate non-core assets and shore up liquidity.
Philadelphia's price tag also stands out against the building's official valuation. Property tax assessment records reviewed by Bisnow put 8800 Tinicum Blvd at $30.4 million in 2026, meaning the city's $42 million purchase landed about 38% above its tax-assessed value — a gap Bisnow's reporting frames as typical of how municipal assessments can lag actual market pricing.
No Tax Dollars, But No Stated Plan Either
Because the Department of Aviation has operated as a standalone municipal agency since a 2022 voter-approved charter amendment, the purchase draws on airport fees, terminal leases, and federal grants rather than the city's general fund, as the Philadelphia Inquirer has reported. What the agency intends to do with the five-story structure remains unclear — whether it becomes administrative office space, gets adapted for cargo and logistics work, or factors into a longer-term master plan for the airport has not been publicly detailed.
The acquisition lands amid a much larger buildout at PHL. The Inquirer reported in March 2026 that the airport is in the middle of a $500 million capital improvement initiative spanning nearly 50 infrastructure and terminal projects, work tied in part to the city's World Cup and 250th-anniversary prep. Cargo growth may be part of the calculus, too: the city's Department of Aviation reported in February 2026 that PHL processed more than 482,000 tons of airmail and freight in 2025, a 7.4% jump from the prior year that outpaced the airport's domestic passenger growth.
For now, 8800 Tinicum Blvd sits in Southwest Philadelphia as city property with an uncertain second act, its five stories empty just as they've been since PNC Bank cleared out more than two years ago.
