Building permits, zoning and septic rules in Robertson County, Tennessee

Yes. Robertson County requires a building permit for new construction, issued to the landowner or a licensed contractor, and construction drawings must comply with the 2021 International Building Codes^1,4. Tennessee also runs a separate State Residential Building Permit program through the State Fire Marshal's Office, but that program applies only in "opt-out" or "non-code" areas that don't enforce their own local codes⁶. Robertson County enforces its own building codes through its Planning Department, so the state program's separate permit fees and inspection process do not apply here; use Robertson County's own permit process and fee schedule instead^1,4.

Robertson County's Planning Department handles building permits and is reachable at 511 S Brown St, Springfield, TN 37172, phone (615) 382-6198⁴. The same department also has a listed contact point at 527 S. Brown St., Springfield, TN 37172, phone 615-384-3666, where it maintains zoning maps and records and issues certificates of occupancy and temporary use permits². The department also conducts inspections as required to ensure compliance, though we could not confirm a published inspection schedule or when a certificate of occupancy is required². A residential building permit costs $.70 per total square foot of livable space plus porches, garages, storage and basements, and the county separately collects an adequate facilities tax of $1.50 per heated or cooled square foot⁴. Mechanical permits and plumbing permits are $100 each¹.

Yes. Robertson County administers a county zoning ordinance and maintains zoning maps and amendment records². Tennessee county zoning authority applies outside municipal corporations, so land inside a city may follow that municipality's rules instead⁷. The Planning Department also administers and interprets the county's Subdivision Regulations, but we could not confirm the approval thresholds, so ask before dividing a tract². Use the zoning map and resolution to confirm the parcel's district, permitted uses and exceptions before relying on a proposed use². Buildings on land devoted to agricultural use and incidental to the agricultural enterprise can receive a narrower exemption from county zoning, but the exemption does not cover land near a state or federal-aid highway, public airport, public park, or the floodplain described by the state rule⁸. Robertson County tells agricultural applicants to inquire before construction⁴.

The Tennessee Department of Environment and Conservation requires a Septic System Construction Permit to install a septic system or repair a faulty one in Robertson County^3,9. Robertson County requires that permit, or a sewer tap receipt, before issuing a building permit; call 615-687-7000 or use the septic service request website listed by the county⁴. Review generally takes about 10 days and must be completed within 45 days of a complete application⁹. After installation, the applicant or installer must notify the state so the system can be inspected and approved before it is covered; the inspection fee is $100 for a conventional system and $200 for an alternative system⁹. A conventional system permit is $400 for design flow up to 1,000 gallons per day, while an alternative-system permit is $500 at that flow; repair permits have no permit fee⁹. Only 42.5% of Robertson County soils avoid a "very limited" rating for a conventional drain field, so make septic feasibility a purchase contingency for a specific parcel⁵. A qualifying utility can require sewer connection where a building lot abuts a public way containing its sanitary sewer¹⁰.

We could not confirm a Robertson County-specific rule allowing residential or long-term RV use, temporary camping, or tiny-home occupancy on private land. Robertson County administers zoning and maintains parcel maps, so ask the Planning Department how the parcel's zoning district treats the proposed dwelling or temporary use before buying or moving one onto the land². We also could not confirm county thresholds for minimum dwelling size, setbacks, lot coverage, building height or accessory dwellings; those questions need a parcel-specific answer from the Planning Department.

1. Get your septic permit or a sewer tap receipt first; Robertson County's own permit page lists this as the first required step, reachable through the septic service request website or 615-687-7000⁴.
2. Get a water tap or meter receipt from your water provider, or a letter of intent or receipt from a well-drilling company if you're using a well⁴.
3. Get a driveway permit from the Robertson County Highway Department, required for all new buildings, or from the state highway department if your access is on a state road^4,11.
4. Get a 911 address verification letter from the Robertson County Emergency Communications Department, required for all new construction⁴.
5. Pull a copy of the recorded deed in the current owner's name from the Register of Deeds office⁴.
6. Prepare a site plan drawing showing the house, roadway, driveway, fencing, other buildings, septic tank and field lines, plus detailed construction drawings that comply with the 2021 International Building Codes⁴.
7. If you're building your own home rather than hiring a contractor, you're limited to one owner-builder permit every two years, and the home can't be for sale, lease or rent; anyone you pay more than $25,000 generally has to be a licensed contractor^1,12.
8. Submit everything to the Planning Department and pay the residential building permit fee plus the adequate facilities tax before construction begins⁴.

Soils and septic: 42.5% of Robertson County's soils rate favorably for a conventional drain field, better odds than many rural counties, but get a site evaluation before you count on it for a specific parcel⁵. Flooding: ask the Planning Department whether your parcel needs a flood elevation certificate, since one may be required before a building permit is issued⁴. Access: a driveway onto a county road needs a Robertson County Highway Department permit, while a driveway onto a state highway needs a separate permit from the state highway department^4,11. Sewer: if your lot abuts a street with sanitary sewer already available, the utility may be able to require you to connect rather than use a septic system¹⁰. Agricultural buildings: a barn or similar structure incidental to an agricultural enterprise can qualify for a narrower zoning exemption, but Robertson County still asks agricultural applicants to inquire before construction^4,8. Taxes: the effective property tax rate here is about 0.5%, or roughly $1,547 a year on a typical home⁵.
