Pittsburgh City Council has given final approval to the housing and zoning package it has been arguing about for more than two years, wrapping up the vote at its Tuesday, Oct. 27 meeting. Bill 2025-1545 drops minimum parking requirements for new development, opens the door to backyard and in-house accessory units across the city, and replaces a proposed citywide affordable-housing mandate with an optional height bonus (via 90.5 WESA and the City of Pittsburgh's Department of City Planning).
Council gave the package a unanimous preliminary vote on Oct. 21 after a last round of amendments, setting up Tuesday's final vote. The city's official meeting record for Oct. 27 was still in draft on Wednesday, so the formal tally hadn't been posted.
For anyone who builds or remodels in the city, the bill comes in three pieces.
Parking minimums are gone. The city's plan removes minimum off-street parking requirements for every use in every zoning district, something Pittsburgh has required in some form since its 1958 zoning code. Existing parking stays put, and owners can still build spaces if they want them. The city also planned to widen parking maximums and further limit surface lots in its densest neighborhoods. Developers who want more parking than the rules normally allow will pay a fee, and council still has to create the trust fund that holds that money.
Accessory dwelling units get much easier. ADUs will be allowed by right as an accessory to a house, a community center or a religious building. City Planning's materials show basement and attic apartments, garage conversions, units over a garage and detached backyard cottages. Homeowners can have up to two ADUs on a residential lot, and the owner doesn't have to live on the property. City Planning's ADU page lists a 1,000-square-foot cap per unit and a 30-foot height limit. WESA reported the ADU and parking changes could take effect as soon as the week after final approval.
The affordable-housing piece is now voluntary. Former Mayor Ed Gainey proposed in September 2024 to require affordable units in larger projects citywide. After months of fights, including an 11-hour Planning Commission meeting in January 2025, council reworked it into an incentive program. Projects that set aside affordable units earn bonus points that translate into extra height, 15 feet per point in the city's June 2026 draft. That draft set rental units at 50% of area median income and for-sale units at 80%, with set-asides from 10% to 20%.
Council's final amendments made affordable units stay affordable for 35 years, up from the 20 years the Planning Commission had recommended. Council also cut the height bonus in some neighborhood business districts, capping projects there at 30 feet, to discourage developers from buying and clearing whole blocks. Developers can skip the units and pay into a housing fund instead. The June draft set that fee at $25 per square foot, with future amounts moved to a fee schedule, but the option can't be used until council creates that fund.
The mandatory rules already in place in Lawrenceville, Bloomfield, Polish Hill and Oakland stay as they are, so the bonus doesn't apply there.
Not everyone on council is sure the carrots are big enough. "I hope that the incentives are strong enough that it does result in affordable projects happening," Councilor Barb Warwick said before the preliminary vote. Councilor Deb Gross, who sponsored the original mandatory version, said, "I didn't expect to be voting yes today, but I will be voting yes."
The package builds on a separate bill council passed in May 2025 that removed minimum lot size per unit and shrank minimum lot sizes in residential districts. That change is already in effect citywide.
Why it matters for Contractors
The ADU rules are the big one for small shops. Two units per lot, no owner-occupancy rule and room for basement, attic and garage conversions means more homeowners and small investors with a legal path to add a rental. That's design-build, framing, MEP and finish work that fits a 2- to 10-person crew. If you remodel in Pittsburgh, it's worth getting comfortable with what an ADU permit set looks like now.
Dropping parking minimums helps on tight infill lots, where finding room for required spaces has killed or shrunk plenty of small projects. Fewer parking variances should mean fewer delays.
The height bonus mostly matters to multifamily developers, but trades that sub on mid-size apartment jobs could see more of those projects pencil out, if the incentives work.
One caution: the specifics above come from the city's drafts and pre-vote reporting. Before you price a job around them, pull the adopted ordinance and confirm the effective date with the city.
