That quiet garage behind your Pittsburgh home keeps draining taxes, insurance, and weekend time. Picture converting it into a code-compliant rental that adds steady cash flow without buying another property.
The opportunity is real, but one wrong move with zoning, permits, or HOA covenants can freeze your project and burn your budget.
This guide translates the City’s ADU rules into plain steps, flags common traps, and shows where the returns come from. Read on to plan confidently and move when the timing is right.
Why ADUs Matter Now
ADUs can turn unused space into income, but success in Pittsburgh depends on timing and compliance. City zoning rules are changing, and private HOA covenants still apply.
Savvy owners know what is allowed, when new rules take effect, and how permits, setbacks, height, parking, and utilities connect.
Do the homework up front, confirm what your HOA permits, and design to the code you’ll build under. With a clear plan, an ADU becomes a steady asset rather than an expensive lesson.
What Pittsburgh Allows Today
Across Pittsburgh, you can’t automatically build an ADU on a residential lot. The Garfield pilot ended in 2020, and ADUs are not a standard by-right use under today’s code.
Your odds depend on your property’s details, like lot size, setbacks, utilities, and whether you can obtain an exception or variance.
Before paying for design work, talk with the Zoning office and confirm what is and isn’t allowed on your parcel, and what approvals, drawings, and inspections you will need.
What Could Change Soon
City Council is considering zoning changes that would allow ADUs across Pittsburgh as an accessory use. The draft limits each ADU to about 1,000 square feet and two stories or 30 feet, allows up to two ADUs per lot, and removes off-street parking minimums.
A public hearing was held on September 10, 2025. These are proposals, not law, so check the final ordinance and effective date before planning or submitting permits.
HOA Realities
City zoning sets the baseline, but it doesn’t override your HOA. Pennsylvania has no statewide law that forces HOAs to allow ADUs, so your community’s covenants can be stricter than city code.
Many HOAs limit secondary structures, separate rentals, parking, or exterior changes. Pull your declaration, bylaws, and design rules early, talk to the architectural review committee, and plan to follow their process.
Get every approval in writing before you spend on plans or submit for permits.
Costs and Feasibility
Expect Pittsburgh ADUs to cost about $225 to $375 per square foot. Many detached backyard units run $200k to $350k. Include utilities, site work, and inspections in your budget.
Use conservative rent comps, add a 10-15% contingency, and confirm licensing, rental registration, and occupancy permits before bidding.
How to Proceed
- Track the ordinance and design only to the adopted rules.
- Hire a code-savvy designer to handle height, setbacks, exits, and utilities.
- Review HOA documents and secure written approvals early.
- Solicit at least three detailed, apples-to-apples bids.
- Arrange financing with a contingency period and inspection.
- Set an operations plan for trash, noise, parking, and ongoing maintenance.
FAQ
Do I need off-street parking for an ADU?
The proposal exempts ADUs from parking minimums, but existing rules apply until the ordinance is adopted. Verify at permit time.
Can I rent both the main house and the ADU?
The proposal omits an owner-occupancy rule and would allow up to 2 ADUs per lot. Confirm the final text before finalizing the lease plans.
