Zoning, building permits and septic rules in Gainesville, Missouri

Rules another office applies inside Gainesville

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

• Septic permitRequired

  Installation or repair of an onsite wastewater treatment system inside Gainesville city limits, if an onsite system is used.

  • Most OWTS installation and repair requires a construction permit.
  • Some single-family residential lots may be exempt.
  • The appropriate permitting agency must be identified for the work location.
  • For residential property under three acres, the cited state FAQ states a permit is required; the exception may not apply in some counties.
  • All non-residential onsite systems require a permit regardless of property size under the cited FAQ.

  residential property size threshold: < 3 acres (The cited FAQ states the exemption does not apply in some counties; check with the county authority.)

  “A construction permit is required to install or repair an onsite system on any residential property less than three acres. (This exemption does not apply in some counties; check with the county authority.) Regardless of the size of the property, a permit is necessary for all other onsite systems that serve non-residential structures.”

  One more reviewed finding on this topic

  • Required — Most onsite wastewater system installation or repair inside Gainesville city limits under Missouri's statewide OWTS framework.

    “A construction permit is required before installing or repairing most onsite wastewater treatment systems (OWTS). Some single family residential lots may be exempt from permitting. The first step of the permitting process is to determine the agency that has permitting authority where the work is being done.”

• Off-grid sanitationLimited

  Off-grid onsite wastewater disposal inside Gainesville city limits where central sewer service is unavailable.

  • State minimum standards cover new onsite systems and major changes.
  • A permit is generally required before construction or repair.
  • Certain residential properties may be exempt from state permitting requirements.
  • A local ordinance may impose more restrictive requirements.

  “Our department has set minimum state standards for OWTS. These standards cover new systems and major changes to existing systems. Some examples of major changes are replacing a sewage tank, and replacing or expanding an absorption field. These standards became effective in January 1996. Generally, a permit must be obtained before starting construction or repair work. However, certain residential properties may be exempt from state permitting requirements.”

• Subdividing landRegulated (with conditions)

  Subdivisions inside Gainesville city limits when onsite wastewater treatment systems are planned.

  • Missouri DHSS covers specified onsite systems, while DNR regulates other wastewater systems.
  • DNR approval is required for subdivisions if onsite wastewater use is planned.

  “DNR must approve subdivisions, mobile home parks and campgrounds if the use of OWTS is planned. Developers as well as property owners in unapproved developments should contact DNR regarding their residential housing unit requirements.”
