Frequently Asked Questions
Can I build an ADU on my Pittsburgh property?
Yes — Pittsburgh allows accessory dwelling units on residential lots. You can build a detached ADU up to 800 sqft in the rear or side yard, or convert a portion of your house into an attached ADU. No owner-occupancy requirement, no additional parking needed, and no impact fees. Pittsburgh's PLI issues building permits, typically taking 4-8 weeks for review.
What are Pittsburgh's short-term rental rules?
Pittsburgh requires a Short-Term Rental License ($175/year) from the Bureau of Building Inspection. A property inspection is required before the license is issued. Occupancy is limited to 2 persons per bedroom and you must provide a 24/7 responsible party contact. Pennsylvania's 6% Hotel Occupancy Tax plus Allegheny County's hotel tax apply — STR platforms handle tax collection.
Is my Pittsburgh property at risk for landslides?
Potentially, depending on your neighborhood. Pittsburgh's steep hillsides in Mt. Washington, Duquesne Heights, Knoxville, and similar areas have known landslide risk. The Pennsylvania Geological Survey and Allegheny County maintain slope stability maps. For new construction on steep slopes (over 15% grade), a geotechnical study is typically required by Pittsburgh's Department of City Planning. Hillside development regulations (Pittsburgh Zoning Code Chapter 902) govern construction on slopes.
How do historic district rules affect my Pittsburgh home?
Pittsburgh has 14 local historic districts, including Mexican War Streets, Allegheny West, and parts of Lawrenceville and Shadyside. If your home is a contributing structure in a Pittsburgh Historic Review Commission (PHRC) district, exterior changes require a Certificate of Appropriateness before a building permit is issued. Interior changes don't require PHRC review. The PHRC reviews windows, doors, siding, roofing materials, and additions for compatibility with historic character.
What should I know about permits for Pittsburgh's older housing stock?
Pittsburgh's housing stock is notably older — many homes date to the early 20th century or late 19th century. Pre-1978 homes have lead paint — lead paint disclosure required for renovation. Pre-1980 structures require asbestos surveys before demolition. Pittsburgh's older homes may have knob-and-tube wiring, cast iron plumbing, and masonry construction that require specialized contractors familiar with historic rehabilitation techniques.
Does Pittsburgh allow solar panels?
Yes — Pittsburgh allows solar installations with an electrical permit from PLI. Duquesne Light interconnection is required for grid-tied systems and Pennsylvania's net metering law requires utility credits for excess generation. Pittsburgh's hilly topography means solar potential varies significantly by property — south-facing slopes have excellent exposure while north-facing or heavily shaded lots may have limited viability. Historic districts have additional review requirements.
