Zoning, building permits and septic rules in Town of Clermont, Indiana

Rules another office applies inside Town of Clermont

Town of Clermont 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 septicState (with conditions)

  A dwelling on land inside Clermont town, IN that is not connected, or cannot be connected, to a sanitary sewer (state rule applies; the local health officer enforces it, which was not confirmed for Clermont)

  • Applies only where the dwelling is not connected, or cannot be connected, to a sanitary sewerage system.
  • 'Sanitary sewerage system' is defined in 410 IAC 6-8.3 (sec. 36) as a sewer system conveying sewage to a treatment facility owned by an incorporated city or town, a conservancy district, a regional sewer district, or a private utility.
  • The 2026 proposed rule filing (410 26-64) was not relied on; only the rule text on the in.gov copy was used.
  • Which local health department enforces this rule for Clermont was not verified.

  “any dwelling that is not connected, or cannot be connected, to a sanitary sewerage system shall be provided with a residential on-site sewage system that includes a septic tank and a soil absorption system that has not failed.”

  • The floodplain administrator and/or designee may issue the permit only if the provisions of the article are met.
  • Other sites in the floodway or flood zone were not checked; the floodplain article was not read in full.
