Building permits, zoning and land rules in Chester County, Tennessee

Yes. Chester County requires a building permit for new construction, additions, renovations, major repairs, manufactured buildings, modular buildings, and other covered construction valued at $2,000 or more¹. General maintenance such as painting, floor coverings, roof coverings, sidewalks, patios, and minor fixture repairs is exempt within the county's stated limits¹. One-story detached residential accessory structures up to 200 square feet are among the listed exemptions, but owners of outbuildings or car covers valued below $2,000 should still ask the building official to approve the location¹. Chester County applies the 2018 International Residential Code with local exceptions, along with its other adopted building codes¹. Permitted work has staged inspections, followed by a final inspection and certificate of occupancy after completion and before anyone moves in¹.

The Chester County Building & Zoning Department is the first call for building, zoning, subdivision, code-compliance, and property-maintenance questions in the county-administered area². The office is at PO Box 183, 159 East Main Street, Henderson, TN 38340, and can be reached at (731) 989-5672 or agaters@chestercountytn.org². Building permits and application forms are obtained from the department in the Chester County Office Building¹. Normal site visits, inspections, and field work occur between 12:30 p.m. and 3:30 p.m., with morning inspections available only by exception¹. Permits expire six months after issuance¹. Fees are based on project value; published examples include a $20 accessory-building permit below $2,000 and a $30 reinspection fee¹. Starting work before obtaining a permit doubles the scheduled fee and does not waive code compliance¹.

Chester County administers zoning in unincorporated areas outside the City of Henderson planning region². Henderson's Building and Zoning Department manages the City of Henderson planning region, while incorporated municipalities may have separate local controls². Ask which jurisdiction and planning region contain the parcel before relying on a zoning answer or submitting an application². In the county-administered unincorporated area, a subdivision plat permit is required when a division needs a new road or public utilities, leaves any lot under five acres, or leaves no access to roads⁶. The five-acre figure is a subdivision-review trigger, not a confirmed general minimum lot size⁶. Numeric setbacks, lot coverage, building-height limits, general minimum lot size, and zoning-district maps could not be confirmed; request the parcel's current standards from the responsible zoning office².

TDEC's Division of Water Resources administers septic permits in Chester County, with septic-related service available through the Jackson Environmental Field Office^7,8. A septic permit is required before construction, modification, or repair, and it should be obtained before dirt work or construction of a building pad begins³. A TDEC Environmental Scientist evaluates the site, and alternative systems require an extra-high-intensity soils map from a licensed Tennessee soils consultant³. Only 8.4% of Chester County soils are rated without severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency⁴. After installation, the installer must arrange a final inspection before covering the system; TDEC issues a Certificate of Completion when it approves the work⁷. Call 731-441-5593 for septic-related inquiries⁸.

Chester County's long-term RV occupancy, temporary-camping, and tiny-home occupancy rules could not be confirmed. Do not treat that gap as permission: zoning administration changes between the City of Henderson planning region, the county-administered unincorporated area, and potentially other municipalities². Before buying or moving a unit onto land, give the responsible zoning office the parcel number and ask about the proposed use, dwelling classification, minimum dwelling size, setbacks, and temporary occupancy during construction². A tiny home within the county's covered construction categories requires a permit when its construction value reaches $2,000, and manufactured or modular buildings are expressly covered¹. Chester County's stated agricultural permit exemption covers nursery or agricultural shade-cloth structures without service systems; it does not establish a blanket exemption for farm buildings⁹. Wastewater work remains subject to TDEC septic permitting³.

1. Ask the Chester County Building & Zoning Department which jurisdiction and planning region contain the parcel, then obtain the applicable zoning and building applications^1,2.

1. Confirm septic feasibility with TDEC before fixing the house location, because only 8.4% of county soils are rated without severe limitations for a conventional drain field^4,8.

1. Resolve county subdivision-plat review if the project divides unincorporated land and triggers review for a new road, public utilities, a lot under five acres, or lack of road access⁶.

1. Obtain the building permit for covered work valued at $2,000 or more; an owner may pull the permit for a private residence but assumes the stated legal and insurance responsibilities¹.

1. Schedule the required construction inspections, keep the septic installation uncovered until inspection, and obtain the building's final inspection and certificate of occupancy before moving in^1,7.

1. Provide the required sewer or septic notice before electrical service is processed, and obtain a TDOT permit if the driveway enters state highway right-of-way^3,5.

Start with jurisdiction and zoning: confirm whether the parcel is in the Henderson planning region, the county-administered unincorporated area, or another municipality, then request its zoning district, setbacks, allowed uses, and any floodplain review^1,2. Make a satisfactory septic evaluation a contract contingency because only 8.4% of county soils are rated without severe limits for a conventional drain field⁴. Private-well permitting and alternative off-grid sanitation rules could not be confirmed, so ask TDEC about wastewater and the appropriate state or local office about the proposed water source⁸. Verify legal road access and ask the Chester County Highway Department about a county-road entrance; a driveway on state highway right-of-way requires a TDOT permit^5,10. Chester County is lightly settled at about 61.6 people per square mile, with 64.7% of its land wooded and 66.2% at a slope of 15% or less⁴. The effective property-tax rate is about 0.5%, and the median annual property-tax bill is about $837⁴.
