Buchanan Ingersoll & Rooney is not budging from Grant Street. The law firm has renewed its lease at the Union Trust Building, keeping its Pittsburgh headquarters planted in the historic downtown tower and locking in more than 115,000 square feet of office space. The deal keeps one of the central business district's biggest office users right where it is.
As reported by Pittsburgh Business Times, the firm has extended its lease and will remain a major tenant in the building, according to reporter Patty Tascarella. The outlet highlighted Buchanan's 115,000-plus square foot footprint as a key detail of the renewal.
Buchanan's Long-Term Bet On Union Trust
Buchanan first agreed in 2017 to relocate its headquarters to the restored Union Trust and made the move official in 2019 as part of a multiyear effort to centralize its Pittsburgh operations. In a 2017 announcement, The Davis Companies said the firm had signed on for roughly 142,000 square feet, and Buchanan's own release at the time framed the shift as a full headquarters transition. The 2016–17 renovation of Union Trust was described as a roughly $100 million project that blended restored historic features with modern amenities.
What The Building Offers
The Union Trust Building at 501 Grant Street has been repositioned as a mixed-use office and retail tower, with restaurants, a fitness center, and preserved public spaces aimed at drawing and keeping sizable tenants. Building profiles and property listings detail the address and current availability, and they also show that Buchanan remains one of the largest occupants in the property.

Why The Renewal Matters For Downtown
The lease extension keeps a sizable employer rooted in downtown at a time when renewals help steady the office market and give nearby street-level retail a reason to hang on. Pittsburgh Business Times framed the deal as a clear win for Grant Street's commercial core.
For landlords and brokers, landing or keeping long-term tenants in Class A properties such as Union Trust eases the pressure of marketing large blocks of space and supports broader efforts to rethink downtown's role. The Buchanan renewal also keeps a flagship law firm in place as building owners continue to court professional-services firms and hospitality businesses that rely on daytime foot traffic, and observers say it underscores the draw of amenity-rich, top-tier space for headquarters and large teams.
