Contact permits@washingtoncountyga.gov or 478-552-2937.
Which codes and exemptions should I review?
N/A; the current county permit sheet describes county development permits and says used-mobile-home inspections may be performed by a certified home inspector, licensed contractor or local municipal building inspector, but it does not identify a specific 2026 building-code edition enforced by the county. County development permits are required for residential or commercial construction, new additions, outbuildings over 400 square feet, new or used mobile homes, RV parks, mobile-home parks, subdivisions with private roads, pool houses and new or rebuilt driveways. The sheet does not identify a general cosmetic-work exemption; outbuildings at or below 400 square feet are not listed among the development-permit triggers.
