Garage conversion rules in McKeesport, PA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions to habitable space require PA UCC building permit and must meet residential code for ceiling height, egress, insulation, and ventilation. Zoning approval also required.
Converting a garage to habitable space (bedroom, office, in-law suite) in McKeesport triggers both zoning review and a PA Uniform Construction Code (UCC) building permit. McKeesport enforces the UCC through its Bureau of Inspections and Underwriting (BIU) per 34 Pa. Code Chapter 403. The 2018 International Residential Code (IRC) — adopted by PA — sets the technical requirements: ceiling height minimum 7 feet (IRC R305.1); one habitable room at least 70 sq ft and no dimension less than 7 feet (R304); natural light equal to 8% of floor area via windows (R303.1); egress window in any sleeping room (5.7 sq ft net opening, 24" high, 20" wide, sill under 44") per R310; smoke and CO alarms per R314/R315; thermal insulation meeting IECC Climate Zone 5 (R-15 wall, R-30 ceiling, R-10 slab perimeter); and a heating system capable of holding 68F at 3 feet above floor (R303.10). Zoning review under the 2017 Zoning Ordinance checks that the conversion does not reduce required off-street parking below district minimums (typically 2 spaces per single-family dwelling); if it does, you must add replacement parking elsewhere on the lot. Creating a separate dwelling unit (kitchen + bath + sleeping area) constitutes an ADU and may trigger additional zoning review, density limits, and occupancy rules.
Work without permit: stop-work order, double permit fees as penalty, and $100-$1,000 fine per UCC §403.42. Unsafe/non-compliant work: mandated removal or reconstruction at owner cost. Unpermitted ADU creating illegal 2nd dwelling: zoning enforcement, up to $500/day until abated.
