Chester County (county seat: Henderson) covers 287 square miles with a population of 17341. Official county website: chestercountytn.org. This page summarizes the verified building-regulation posture of unincorporated Chester County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
Chester County is on the State Residential Building Program (SRBP), so new one/two-family dwellings on unincorporated land require a state residential building permit and inspection through the State Fire Marshal.
The claim above is source-verified (official statute/county documents; URL, direct quote, and date on the full card). Method: how we verify.
No county's freedom erases state law: septic/wastewater permitting (health authority), well permits and water rights (state engineer/DNR), floodplain rules with federally connected financing, and — in some states — state-run electrical inspections. The full card details which of these bite in Chester County and how hard.
The score describes unincorporated county land only. Inside Chester County, incorporated municipalities set their own, usually stricter, rules — including: Henderson (EXEMPT — city codes/zoning + planning region), Enville, Milledgeville, Silerton (SRBP). Land inside town limits follows town code.
Building rules are the first question people ask about Chester County — and the easiest one to answer. They're rarely the one that decides it. The full card grades all ten dimensions, every claim quoted from the county's own code.
