How are inspections scheduled?
Call the automated 24-hour inspection request line at 865-458-4680 with at least 24 hours' notice and provide the permit number, site address, inspection type, caller name and phone, and requested date/time. Minimum stages include footing, slab, rough framing/plumbing/mechanical, energy, and final inspections. Post the permit visibly from the public road, keep approved drawings on site, and leave the structure unlocked or arrange inspector access. Electrical inspections are conducted separately by state inspectors through the utility provider.
Which codes and exemptions should I review?
Effective July 1, 2023, Loudon County adopted the 2018 International Building Code, International Residential Code, International Plumbing Code, International Mechanical Code, International Fuel Gas Code, International Existing Building Code, and International Energy Conservation Code, plus ICC A117.1-2017, all with county amendments. These apply in unincorporated Loudon County and incorporated areas that have not adopted their own corresponding code. State inspectors perform electrical inspections through the utility provider. The 2018 IRC exemptions retained by the county include qualifying one-story detached accessory structures not over 200 square feet; fences (the county amendment removes the model code's height limit); qualifying retaining walls and small water tanks; sidewalks and driveways; painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work; prefabricated pools under 24 inches deep; swings and playground equipment; qualifying wall-supported window awnings; and certain small, low, detached decks. The zoning resolution also bars county building permits for agricultural structures incidental to an agricultural enterprise, subject to its stated proximity exception near highways, public supports, or parks. Confirm applicability before work.
