The county also administers zoning countywide, and TDEC requires a separate septic construction permit for a new system or repair23.

Do you need a building permit in Marshall County, Tennessee?
Yes. Marshall County requires a residential or commercial building permit for construction, most exterior renovation and remodeling, and every addition1. Routine maintenance and repairs do not require a permit1. Permitted construction is inspected for compliance with minimum construction standards, zoning and setback requirements12. Marshall County has adopted residential, building, mechanical, plumbing, fuel-gas and life-safety codes, along with an energy-conservation code13. Do not begin regulated work early: the county says starting before the permit is received results in a charge of double the normal permit fee1.
Who issues Marshall County building permits, and how do you reach the office?
Marshall County Building Codes and Zoning handles the county's building-permit, inspection, zoning, planning and flood-development submissions4. The office is at 206 Legion Avenue, Suite A, Lewisburg, TN 37091, and the phone number is (931) 359-05674. The county directs applicants to its respective portals for applications, inspection requests, questions, complaints and other submissions4. The accessible county page does not publish a complete review timeline or every required application item, so use the office's portal or call with the parcel number and project description before preparing a filing144.
Does Marshall County have zoning?
Yes. Marshall County administers zoning countywide and publishes an interactive map where a buyer can search a parcel and view its zoning information215. Setbacks are not one countywide distance: front, side and rear minimums vary by zoning district, and the county directs applicants to the Zoning Office for the applicable dimensions10. The current materials do not confirm countywide minimum dwelling size, minimum lot size, lot coverage or building-height limits, so ask Building Codes and Zoning to read the current rules for the specific parcel4. Tennessee's agricultural zoning exemption is conditional: the land must be devoted to agriculture and the structure incidental to that enterprise, with exceptions including certain nearby public facilities and floodplain land16.
How do septic permits work in Marshall County?
TDEC administers subsurface sewage disposal permitting in Marshall County, and a Septic System Construction Permit is required to install a new system or repair a faulty one73. TDEC inspects each installation for compliance with the permit conditions and regulatory requirements17. The Columbia Environmental Field Office serves Marshall County; call (931) 380-3371 or email [email protected] for Division of Water Resources assistance18. Only about 6% of Marshall County soils rate without severe limitations for a conventional drain field, so confirm a usable septic area before choosing a house site11. A qualifying utility may require an existing building on an abutting parcel to connect when a sanitary sewer is available along the public way, but that authority does not mean sewer serves every parcel19.
Can you live in an RV or tiny home on land in Marshall County?
We could not confirm a county rule that answers long-term RV occupancy, temporary camping or tiny-home occupancy on private land in Marshall County. Because Marshall County administers zoning countywide and setbacks vary by district, take the parcel number and the proposed structure and occupancy to Building Codes and Zoning before buying or moving a unit onsite2104. A tiny home does not automatically avoid permitting: Marshall County requires permits for construction, most exterior renovation and remodeling, and all additions1. Manufactured-home occupancy, accessory dwellings and a countywide minimum home size also remain unconfirmed; the Building Codes and Zoning office can identify the current parcel district and submission route4.
Building a home in Marshall County: the steps, in order
- Ask Building Codes and Zoning to identify the parcel's zoning and the applicable setbacks1510.
- Confirm septic feasibility and apply to TDEC for the required construction permit if the site will use a subsurface system318.
- Submit the county building and zoning materials through the appropriate county portal144.
- Receive the building permit before starting, because early work triggers double the normal permit fee1.
- Request county inspections through the portal as construction proceeds124.
- Have TDEC inspect the installed septic system for compliance with the permit17.
- If the driveway enters a Tennessee state highway right-of-way, obtain the TDOT entrance permit before construction or a change in use20.
What should you check before buying land in Marshall County?
Start with parcel zoning, setbacks, legal access, flood status, water source and septic feasibility. The county's interactive map provides parcel zoning, while flood-development submissions go through the county portal154. Only about 6% of county soils rate without severe limits for a conventional drain field, even though about 74.5% of the land has a slope of 15% or less, so evaluate the actual homesite rather than county averages alone1121. A private-well permit rule and countywide water-connection requirement could not be confirmed; ask Building Codes and Zoning and TDEC which authority applies to the parcel418. The effective property-tax rate is about 0.5%, and the median annual property-tax bill is about $1,3342223.
Watch-outs
- Starting regulated work before Marshall County issues the building permit triggers a charge of double the normal permit fee1.
- Marshall County setbacks vary by zoning district, so do not place a house, garage or storage building from a generic setback figure10.
- RV living, temporary camping, tiny-home occupancy and private-well permitting remain unconfirmed; ask Building Codes and Zoning and TDEC about the parcel before committing to land418.
