Fixing Uneven Floors
Fixing uneven floors in Philadelphia involves considering your home's age and local permit rules. Older homes may need different approaches based on materials and building codes. Permits and timelines also affect the process.
Philadelphia's building permit filing fee for one- or two-family dwellings is $25, plus a $3 city and $4.50 state surcharge (City of Philadelphia - Get a Building Permit) This fee applies if you need to level floors by altering the subfloor structure. If your home was built before 1978, lead-safe renovation rules apply when disturbing old paint during floor work (ACS 5-year 2020-2024, B25034 Year Structure Built). Always check for lead hazards in pre-1978 homes before starting any flooring project involving sanding or removal of painted surfaces.
If your home is among them, leveling might require reinforcing the underlying structure. These codes may affect how you install new flooring over existing uneven surfaces, especially if you're adding a second layer.
