Zoning, building permits and septic rules in Hartville, Missouri

Rules another office applies inside Hartville

Hartville 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)

  Onsite wastewater work inside incorporated Hartville city limits.

  • Hartville is identified as a city by Wright County.
  • The DHSS process states that, within incorporated areas, the local permitting authority defers the permit process to DHSS.
  • DHSS regulations cover single-family residential systems including lagoons and specified systems of 3,000 gallons per day or less; other systems may be regulated by DNR.

  “Some cities in Missouri are incorporated and may not fall under the local permitting authority even when an ordinance is in place. If work is being done within one of these incorporated areas, the local permitting authority will defer the permit process back to DHSS.”

  • Some single-family residential lots may be exempt from permitting.
