Decision path

Five checks to start in Tennessee

  1. 01

    Septic records and new capacity

    Search TDEC permit records and confirm whether any existing approval matches the parcel, bedroom count, system location and current project.

  2. 02

    County and municipal jurisdiction

    Determine whether zoning, subdivision, building or planning review applies through the county, city or growth boundary.

  3. 03

    Access and topography

    Evaluate private roads, easements, driveway grades, drainage and construction access, especially on ridge and hollow parcels.

  4. 04

    Flood and stream constraints

    Review FEMA maps, local floodplain rules, stream crossings and drainage before placing roads, homes or septic systems.

  5. 05

    Greenbelt and carrying cost

    Ask the assessor whether agricultural, forest or open-space treatment is active and what sale or use change could do to taxes.

Common warning signs

Do not leave these claims unverified.

  • Old septic permit does not match proposed bedrooms.
  • “No zoning” is treated as no building or health rules.
  • Driveway crosses a creek without approved structure.
  • Greenbelt tax is assumed to continue automatically.
  • Utility extension follows a private route with no easement.
