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

Yes. Maury County requires a building permit before covered construction, reconstruction, extension, conversion, structural alteration, moving, use changes or filling begins^1,9,10. County-reviewed structures are subject to adopted building codes, including county-listed 2018 building and commercial codes⁹. Residential applications require plans, a plot plan, septic documentation, water-source proof, driveway approval and applicable licenses^2,10. Conventional construction receives footing, foundation, framing, plumbing, mechanical, energy and final inspections; schedule inspections at least 24 hours ahead^2,9,10. A final inspection and blower-door test precede the certificate of occupancy^2,11.

The Maury County Building & Zoning Office handles building permit applications and inspections for unincorporated Maury County, Tennessee¹⁰. Reach the permit counter at 931-375-3006 or visit the Walter Harlan Building at 5 Public Square in Columbia⁸. The same department supports county planning and zoning and provides an interactive zoning map¹. Residential applications go there with septic, water-source, driveway, plan, plot-plan and licensing materials^2,10. Maury County publishes valuation-based building permit fees that include building, plumbing and mechanical permits; the New Development Tax is paid separately². Flood-hazard, geotechnical or State Fire Marshal circumstances can require more documentation².

Yes. Maury County administers zoning in the unincorporated county; Columbia, Mount Pleasant and Spring Hill administer their municipal areas^3,4,5. The ordinance and zoning map publish district-specific uses, lot sizes, setbacks and lot coverage, so the answer depends on the parcel's district^3,5,11. For example, minimum lots range from 1 acre in RG to 15 acres in AP, while front setbacks range from 30 feet in CRC to 100 feet in AP⁵. The permit packet's general residential setback summary is 40 feet in front, 30 feet in back and 20 feet on the sides, but district rules may differ¹⁰. Check the county zoning map with Building & Zoning before designing.

The Tennessee Department of Environment & Conservation handles septic permitting for Maury County^6,10. A TDEC septic permit is required documentation when a residential building-permit application uses on-site septic^2,10. The Columbia field office listed by the county is at 1421 Hampshire Pike⁸. After installation, the installer must notify TDEC, which inspects the system for compliance¹². Only about 24% of Maury County soils rate free of severe limitations for a conventional drain field, so do not assume a standard system will fit the parcel¹³. A qualifying utility can require sewer connection for a building on a parcel abutting a sewered public way¹⁴. We could not confirm whether a private well needs a permit; ask Building & Zoning what water-source proof it will accept.

We could not confirm a general Maury County rule allowing or prohibiting RV residence, temporary camping or tiny-home occupancy on an individual unincorporated parcel. The ordinance does limit occupancy in a county travel-trailer park to 30 consecutive days, but that park rule does not answer private-lot occupancy⁵. Ask Building & Zoning how the parcel and proposed use are classified^3,8. A small dwelling is not automatically an accessory dwelling: where an accessory dwelling is allowed, only one is permitted per lot, its size is capped, and a deed restriction must be recorded before zoning and building approval^2,4,10. A manufactured home is separate; proof of age is required, and a unit over 15 years old is not permitted².

1. Identify the zoning district and confirm that the proposed use, minimum lot, setbacks and lot coverage fit its standards^3,5.
2. Confirm whether a lot split needs planning approval; subdivision review considers septic, drainage, flood hazards and access^2,15.
3. Obtain the TDEC septic permit for an on-site system and proof of a water tap or other water source^2,10.
4. Get Highway Department approval for a county-road driveway, or contact TDOT for a state-road connection^2,10.
5. Submit plans, the plot plan, approvals and applicable licenses to Building & Zoning^2,8. An owner acting as contractor must include a deed copy and follow Tennessee licensing limits^2,7.
6. Pay the building permit fee and New Development Tax separately².
7. Complete inspections and obtain the certificate of occupancy².

Confirm the parcel's zoning district, permitted use, minimum lot, setbacks and lot coverage before making an offer^3,5. Check the lot history because some splits require planning approval before a home or mobile-home permit can issue². Have TDEC evaluate septic suitability: only about 24% of Maury County soils rate free of severe limitations for a conventional drain field^6,13. Confirm the water source and driveway path because both enter the residential application². Agricultural land is not automatically permit-free; county classification is required, and the exemption does not waive wastewater or floodplain limits¹⁶. Development in a Special Flood Hazard Area requires a floodplain development application before work and completion-stage elevation documentation^5,11. Maury County's effective property-tax rate is about 0.5%, with a median annual bill near $1,476¹³.
