Do you need a building permit in Loudon County, Tennessee?

Residential construction in unincorporated Loudon County, Tennessee requires a county building permit1. Loudon County enforces adopted building, plumbing, mechanical and residential codes13. County inspections include footings, slabs, framing, plumbing, mechanical, energy and final work; state inspectors through the utility provider handle electrical inspections6. Homeowners acting as their own contractor must comply with T.C.A. 62-6-103 and still supply the ordinary building-permit materials and applicable approvals514. Farragut, a town mainly in Knox County that reaches into Loudon County, handles its own building permits inside town limits15. For addresses in Loudon County, septic permitting remains with TDEC’s Division of Water Resources3.

Who is the Loudon County building department, and how do you reach them?

Loudon County Planning and Codes Enforcement is at 101 Mulberry Street, Suite 101, Loudon, TN 37774; call Codes Enforcement at 865-458-4470 or the Inspection Hotline at 865-458-468016. Residential building-permit applications are completed in the office, and the published checklist calls for an approved address, applicable septic and driveway permits, a site plan, building-size and construction-cost information, contractor licensing and insurance, school-facilities privilege-tax documentation and payment, and owner signatures17. Building-permit fees vary with factors such as project scope, square footage, valuation or development intensity; ask Codes Enforcement for the current amount because we could not confirm a complete fee schedule1816. For zoning questions, call the Planning Office at 865-458-205519. Septic permits belong to TDEC's Division of Water Resources; apply online or call its Knoxville Field Office at 865-594-6035203.

Does Loudon County have zoning?

Loudon County zoning applies outside municipal corporations, and land uses and structures must follow the parcel’s district rules2. The county planning commission represents unincorporated land and Greenback; the Loudon City planning commission represents Loudon and Philadelphia21. Farragut, mainly in Knox County but extending into Loudon County, administers its own zoning inside town limits; TDEC handles septic permits for Loudon County addresses223. County district boundaries come from zoning maps and amendments maintained in the Building Commissioner’s office23. In county R-1, minimum lot area is 21,780 square feet, with an existing-lot exception subject to public-water and minimum-area conditions8. R-1 building coverage, including accessory buildings, cannot exceed 40 percent of lot or buildable area, whichever is less10. R-1 setbacks include a 30-foot front yard, 25-foot principal-building rear yard and 15-foot side yards for one- and two-story structures9. R-1 height is limited to 3 stories or 36 feet, subject to the ordinance’s exception24. Minimum dwelling size and accessory-dwelling rules could not be confirmed; ask the Planning Office19.

How do septic permits work in Loudon County?

TDEC's Division of Water Resources, not Loudon County, administers septic permits3. A septic permit is required for a new system and for repair or modification of an existing system, and the county building-permit checklist requires the septic permit when applicable417. Apply online or call the Knoxville Field Office at 865-594-6035; local Division of Water Resources staff no longer keep office hours20. After installation, the installer must arrange a final inspection before covering the system, and approval leads to a Certificate of Completion25. Only about 34.1% of Loudon County soils rate free of severe limits for a conventional drain field, so make septic suitability a purchase contingency26. Rules for off-grid sanitation could not be confirmed; ask TDEC before choosing an alternative system20.

Can you live in an RV or tiny home in Loudon County?

Private-parcel RV living and tiny-home occupancy in unincorporated Loudon County could not be confirmed; ask the Planning Office about the parcel, dwelling classification, proposed duration and utility plan19. County-regulated RV-park camper sites are rental-only and may not be sold or leased for longer than 29 days7. Regulated RV parks must supply underground water, sewer and electric service to the clubhouse and all RV sites; RV-site water and sewer need approval from the county health department or appropriate utility district27. Tent camping associated with regulated RV parks is restricted to designated open-space areas and parking capacity, within 200 feet of clubhouse/restroom facilities; primitive camping is exempt from these RV-park regulations28. Those park standards do not establish residential occupancy rights on private land728. Mobile homes are expressly permitted in some county districts, including R-1, with building, septic, floodplain and other applicable requirements still applying29.

How do you build a home in Loudon County, step by step?

  1. Identify the planning jurisdiction and zoning district; county zoning applies outside municipal corporations, while municipalities may use separate ordinances30.
  2. Confirm the proposed use, minimum lot area, lot coverage, setbacks and height with the Planning Office before finalizing a site plan81092419.
  3. Obtain the approved address and, where applicable, the TDEC septic permit and driveway permit listed on the county checklist17. A driveway onto state-highway right-of-way separately requires a TDOT entrance permit31.
  4. Complete the residential building-permit application in the county office with the site plan, building-size and cost information, contractor documents, tax documents and signatures17.
  5. If acting as your own contractor, meet the owner-builder conditions without skipping the ordinary permit approvals14.
  6. Schedule the required construction-stage inspections and arrange the septic final inspection before that system is covered3225.

What should you check before you buy land in Loudon County?

Start with jurisdiction and zoning because county rules apply outside municipal corporations and municipal ordinances may differ30. Subdivision regulations cover Loudon County and the municipal and regional jurisdictions of Lenoir City and Loudon11. If a tract will be divided, a qualifying subdivision needs plat approval before recording; the cited definition excludes divisions where the resulting parcels are at least 5 acres12. About 52.2% of Loudon County land has a slope of 15% or less, while 48.2% is wooded, so inspect the driveway route and build area on foot3334. Only about 34.1% of soils rate free of severe limitations for a conventional drain field26. County-designated floodplain or floodway areas can trigger additional floodplain-development review alongside zoning and building requirements35. Private-well permitting could not be confirmed; ask Planning and Codes Enforcement what approvals apply to the parcel16. The effective property-tax rate is about 0.4%, with a median annual bill near $1,1633637.

Watch-outs

  • The RV-park stay limit does not establish whether you may live in an RV on a private parcel; ask the Planning Office about the specific parcel and proposed occupancy3819.
  • R-1 lot size, coverage and setback rules are district-specific, so do not apply them to land in another zoning district8109.
  • A driveway onto state highway right-of-way needs a separate TDOT entrance permit31.
