Zoning, building permits and septic rules in Hamilton Township, Indiana

Rules another office applies inside Hamilton Township

Hamilton Township does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

• Who permits septicCounty (with conditions)

  On-site sewage (septic) systems for homes built on land inside Hamilton township, Sullivan County, Indiana. The county health department runs the permit process countywide; the guidance found does not carve out Hamilton township.

  • Sullivan County Health Department permitting process requires an onsite system application, a soils analysis by an IRSS certified soil scientist, floor plans, and plan approval before a permit issues.
  • The guidance found is undated; the health department's service-area wording was not opened and should be confirmed.
  • Board minutes from July 2023 (seen only as a search snippet, not opened) say the county septic ordinance needed revision after July 1 under new Indiana Code changes, so current rules may differ.

  “complete a sullivan county onsite system application and return it to the sullivan county health department.”

• Septic permitRequired

  Installing, repairing, replacing or altering an on-site sewage system on land inside Hamilton township, Sullivan County, Indiana

  • A permit is issued only after the installation plans are reviewed and approved; the health department may make a site visit and the system designer must make required corrections.
  • The soils analysis is done by an IRSS certified soil scientist before application.
  • The property owner is responsible for making sure the permit is obtained before the system is installed, repaired, replaced or altered.
  • The permit must be kept at the site during all phases of installation.
  • The county's own note says the owner remains responsible even when contractors do the work.

  septic permit fee: 100 USD (Stated in the county's permitting guidance (undated). The county health fee ordinance (2022) lists an on-site sewage system permit line, but its amount is illegible in the scanned copy, so the $100 figure is not confirmed against the ordinance.)
