Do you need a building permit in Hardeman County, Tennessee?
Yes. Hardeman County requires a permit for construction of any building or addition, and all mobile homes must purchase a permit.1 Agricultural buildings on land devoted to agricultural uses are excluded from the county zoning-compliance-permit requirement under the zoning resolution's general provisions.11 Hardeman County participates in Tennessee's State Residential Building Program for residential code administration.3 The state program applies the 2018 International Residential Code, with amendments, to one- and two-family homes and townhomes where a qualifying local government has neither taken over enforcement nor opted out.12 A county certificate of occupancy is required before land, a building, or part of a building erected or altered under the zoning resolution is used.13 A state residential permit does not replace county zoning, floodplain, septic, electrical, grading or sewer approvals.14
Who issues Hardeman County building permits, and how do you reach them?
Hardeman County Zoning Compliance issues zoning permits, which the county page also labels building permits, and handles subdivision plat approval, rezoning, variances and uses permitted on appeal.5 The office is at 100 N Main Street, 2nd Floor, Bolivar, TN 38008; call (731) 658-5412 or email hczoning@aeneas.com.5 When a site plan is required, a licensed engineer or licensed surveyor must prepare and stamp it for Planning Commission review; uses permitted on appeal go to the Board of Zoning Appeals before a zoning-compliance permit or certificate of occupancy may issue.11 Site-plan approval remains effective for 1 year.11 The same office enforces the county's flood-zone regulations, so it is also the first county contact when a proposed house site may be in a mapped flood area.5 A subdivision plat must receive Planning Commission approval before the Register of Deeds may record it.15
Does Hardeman County have zoning?
Yes. The Hardeman County Zoning Resolution establishes 11 zoning districts in the Hardeman County Planning Region, each with its own allowed land uses.16 Lot size, setbacks, building coverage and height depend on the applicable district and use.10171819 The reviewed district provisions cap general and accessory-building height at 35 feet, with stated exceptions for certain appurtenances that meet code and property-line separation conditions.19 A lot must be at least 1 acre where the county environmentalist requires that size because of soil characteristics.10 Manufactured or mobile homes on individual lots are allowed in the Forestry-Agriculture-Residential district, subject to a county permit.20 Agricultural buildings on land devoted to agricultural uses are not subject to county zoning-compliance permits or regulation under the resolution's stated general-provision exception.16
How do septic permits work in Hardeman County?
The Tennessee Department of Environment and Conservation, not Hardeman County, handles septic permitting and inspection because Hardeman is not a contract county.4 Obtain the septic permit before starting dirt work, a building pad or building construction, as well as before installing, modifying or repairing the system.6 Applications and fees may be submitted through TDEC's service-request form, with property, site, soils-map and design information as required; paper applications remain accepted at the appropriate environmental field office.21 The installer must notify TDEC when installation is complete, and the system must be inspected and approved before it is covered.22 The TDEC Jackson Environmental Field Office lists Hardeman County for septic-related services and publishes 731-441-5593 for inquiries.23 USDA soil data rate 0% of county soils as free of severe limits for a conventional drain field, so make septic feasibility an early purchase contingency.24
Can you live in an RV or tiny home on land in Hardeman County?
Tennessee prohibits using a ready-removable structure for residential, recreational or emergency housing; this includes a tiny-home unit if it has no foundation, footings or other support mechanism and can be easily relocated.7 A structure outside that definition may be treated as a dwelling only if it satisfies the applicable construction, inspection, permit, code, foundation, footing and anchoring requirements.7 Hardeman County's zoning and building-permit rules still apply, and we could not confirm how the county treats other tiny-home designs or long-term RV living on private land.15 Ask Hardeman County Zoning Compliance about the exact design, parcel district, duration and utilities before buying or moving a unit.5 Mobile homes require a county permit and are expressly allowed on individual lots in the Forestry-Agriculture-Residential district.120
Building a home in Hardeman County: the steps, in order
- Call Hardeman County Zoning Compliance at (731) 658-5412 to confirm the parcel's zone, allowed use, setbacks, height limit, flood status and required county application.519
- If a site plan is required, have a licensed engineer or licensed surveyor prepare and stamp it for Planning Commission review.11
- If subdividing land, obtain Planning Commission approval of the subdivision plat before recording it.15
- Contact TDEC's septic service at 731-441-5593 and obtain the required septic permit before dirt work, a building pad or building construction begins.236
- Confirm legal street access: subdivision and zoning-compliance rules generally require the lot's access street to have public-street status or approved equivalent, while a driveway on state highway right-of-way needs a TDOT permit.2526
- Submit the county permit application before constructing a building or addition; mobile homes also require a county permit.1
- Coordinate the applicable county, state residential and septic inspections, then obtain the county certificate of occupancy before using a new or altered building.32213
What should you check before buying land in Hardeman County?
Confirm the zoning district, permitted use, setbacks, height limit, minimum lot size and flood status with Hardeman County Zoning Compliance before the due-diligence period ends.21017195 A site plan in a FEMA special flood hazard area must show the minimum 100-year base-flood elevation, so flood review can affect where a house may sit.27 Treat septic feasibility as a major purchase contingency because USDA data rate 0% of the county's soils as free of severe limits for a conventional drain field.24 Ask the serving utility whether sewer connection is mandatory; Tennessee allows certain sewer utilities to require an existing building on an abutting parcel to connect and stop using another sewage-disposal method.28 Confirm that the lot has qualifying street access before buying; subdivision and zoning-compliance permits can depend on the access street's legal status and construction progress.25 If access is from a state highway, TDOT requires an entrance permit before constructing or changing the driveway.26
Watch-outs
- Hardeman County's permit requirement covers any building or addition and every mobile home, but the zoning resolution excludes agricultural buildings on land devoted to agricultural uses; ask Zoning Compliance to confirm that a proposed farm building qualifies.1115
- USDA data rate 0% of Hardeman County soils as free of severe limits for a conventional drain field, making a TDEC site evaluation a critical early step.2423
- Tennessee prohibits housing in a ready-removable structure, while Hardeman County's treatment of other tiny-home designs, RV occupancy, temporary camping and minimum dwelling size remains unconfirmed; ask Zoning Compliance about the exact parcel and proposal.75

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
