Zoning, building permits and septic rules in Village of Monticello, Missouri

Rules another office applies inside Village of Monticello

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

• Septic permitLimited

  Onsite wastewater-system installation or repair inside Monticello village limits when state OWTS requirements govern.

  • A construction permit is required for most OWTS installations or repairs.
  • Some single-family residential lots may be exempt.
  • The responsible permitting agency depends on where the work is performed; no official source located identifies the authority for incorporated Monticello.

  “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.”

• Off-grid sanitationLimited

  Use of an onsite wastewater treatment system inside Monticello village limits where central sewer service is not available and state OWTS requirements govern.

  • An onsite system is used where central sewer service is unavailable.
  • Installation or repair generally requires a construction permit, subject to exemptions and the responsible local permitting authority.

  “An estimated 25% of homes in Missouri rely on an onsite wastewater treatment system (OWTS) in areas where public sewers are not available.”

• Well permitLimited

  Private-well construction inside Monticello village limits.

  • The state regulates private-well construction and installation under the Water Well Drillers Act.
  • This evidence does not establish a separate Village well-permit process.

  “Private well construction has been regulated in the state since 1985 when the Missouri Water Well Drillers Act became law establishing well construction standards.”
