Do I need a permit for interior remodeling in Fairfax County?
It depends. Whether interior remodeling needs a permit in Fairfax County comes down to the details of your project.
Under the Virginia USBC (13VAC5-63-80, Section 108.2), purely cosmetic work such as painting, wallpaper, floor finishes, and installing cabinets or counters is exempt from a permit, but moving or removing walls, or any electrical, plumbing, or mechanical change, requires a permit. Removing or altering a load-bearing wall is structural work and is never exempt. A remodel that moves walls or includes electrical, plumbing, or mechanical work falls outside cosmetic exemptions, which cover finishes such as paint, flooring, trim, and cabinets. Each trade normally needs its own permit and inspection on top of the building permit, and removing or altering a load bearing wall usually requires a beam detail or engineering before the work is approved. Opening walls in an older home can trigger separate lead paint, asbestos, and smoke alarm requirements, so raise those with your department at application time.
