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

Rules another office applies inside Village of Darlington

Village of Darlington 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 Darlington village, where the local permitting authority defers the permit process to DHSS.

  • DHSS lists DHSS as the agency and DHSS as the authority type for Gentry County.
  • The state page says incorporated areas may not fall under local permitting authority and that the local permitting authority will defer the permit process back to DHSS.
  • Lagoons serving anything other than a single-family residence are under DNR jurisdiction.

  “Agency: DHSS Authority Type: DHSS Address: 930 Wildwood Dr, Jefferson City, MO 65102 County: Gentry Phone: (573) 751-6095 ext. 5 Website: N/A Alert: Submit the information at OWTS Application Number Request Form to request an application number.”

• Septic permitRequired

  Installing or repairing most onsite wastewater treatment systems inside incorporated Darlington village, subject to DHSS permitting jurisdiction.

  • Some single-family residential lots may be exempt from permitting.
  • Work should not begin until a permit has been issued or an exemption has been confirmed by the appropriate permitting authority.
  • Application fees associated with onsite sewage disposal system construction, modifications, and repairs are temporarily suspended effective August 28, 2026.

  “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.”

• Well permitRequired

  Construction of a water well inside Darlington village by a well driller or pump installer who charges for services.

  • Landowners who drill their own well or install their own pump are exempt from permit requirements but must comply with all other rule sections.

  “Well drillers and pump installers who charge for their services must have a permit to construct a well. Issuing permits to well drillers and pump installers establishes a minimum standard of competency and enables the department to enforce minimum construction standards. Landowners who drill their own well and/or install their own pump are exempt from permit requirements, but must adhere to all other sections of the rules.”

• Subdividing landLimited
