Pittsburgh Zoning Code Amendment Expands Accessory Dwelling Units Across Residential Districts
The updated rules allow property owners in areas including Squirrel Hill and Greenfield to add secondary units, increasing the supply of smaller rental homes for city workers.
How we reported this
The Pittsburgh City Council passed the mayor's zoning code amendment on accessory dwelling units last week. The change permits secondary housing structures on single-family lots in designated residential zones. Residents in Squirrel Hill, Greenfield and parts of the South Side now qualify to apply for permits to build or convert space into additional units.
The amendment follows the city's 2025 housing assessment, which documented rising demand for smaller rental options near employment centers in Oakland and Downtown. Council members cited the need to address limited housing stock without altering existing neighborhood density rules. The legislation takes effect on August 1.
Permit Process and Eligibility
Under the new rules, property owners can add one accessory unit per lot if the structure meets size limits and off-street parking requirements. Applications go through the city's Department of City Planning, with fees set at $450 for review. Local advocates note that the process favors owners who already hold clear titles in established neighborhoods.
Workers seeking rentals near universities and hospitals stand to gain the most immediate access. Young professionals and service employees in Oakland face fewer options for one-bedroom units under current stock. Homeowners in Brookline and Carrick, outside the initial eligible zones, cannot apply until a later phase of reviews.
Budget Figures and Next Steps
City budget documents allocate $2.1 million for staff support and permit processing through 2027. The figure covers three new planning positions and software upgrades for tracking applications. The government projects 180 permits issued in the first year based on similar programs in peer cities.
Implementation begins with public workshops scheduled for July 15 at the City-County Building. Property owners must submit site plans and neighbor notification forms. Further neighborhood expansions remain under study by the planning commission, with a report due in December.
