Pittsburgh ADU Permit Fees & Cost Calculator

Pittsburgh’s official zoning engagement page says ADUs are permitted by right as an accessory use and allows up to two ADUs per residential lot, but the city’s public fee schedule does not appear to publish a dedicated ADU fee table. The clearest official cost item found is the city’s valuation-based permit fee schedule, while impact fees and school fees were not identified in the official sources reviewed.

ADUFee.com is not affiliated with Pittsburgh. Estimates are informational and should be verified with the city, utility providers, and qualified professionals.

Step 1 of 5: Location

The calculator uses staged city data from the ADUFee database with visible confidence levels and dated source tracking.

Fee overview

The fee schedule reviewed does not clearly expose an ADU-specific line item, so the actual permit fee must be calculated from current valuation and reviewed with the city.

Non-official websites conflict on whether Pittsburgh broadly allows ADUs; the official Engage PGH page is the controlling source used here.

Utility, school, and impact fees may exist in some form but were not confirmed in the official sources reviewed.

The user is asking for city-level ADU permit and pre-development fees, not construction costs.

Only official city sources were used because no official ADU-specific fee table was found.

Pittsburgh fee estimates should be verified against the current city, utility, and school district fee schedules before filing.

FAQs

Are Pittsburgh ADU fee estimates official?

No. ADUFee.com provides planning estimates only. Final fees are set by the city, utility providers, school district, and other agencies.

What sources are used for Pittsburgh?

The database stores city, state, utility, school, county, and other source links where available. Each estimate should still be verified locally.

Can ADU fees vary within Pennsylvania?

Yes. Permit, utility, school, inspection, and impact fees can vary by jurisdiction, parcel, project size, utility provider, and local interpretation.
