Zoning, building permits and septic rules in Desloge, Missouri

The City of Desloge, Missouri adopts its own zoning (City Code Chapter 405)1 and runs its own building department, which reviews plans, issues building permits and inspects work2. Septic systems inside city limits need city and Missouri Department of Natural Resources approval and a lot of at least 3 acres3. Septic permits themselves come from the St. Francois County Health Center4.

Does Desloge, Missouri have zoning?

Yes. Desloge's zoning regulations are City Code Title IV, Chapter 405, and apply to land inside city limits1. Rules differ by district, so check which district a lot is in before you buy.

In the R-1 Single-Family Residential district, lots need 10,000 square feet and 100 feet of width, though a lot recorded before zoning was adopted can still receive a single-family dwelling5. Dwellings in R-1 need 25 feet front and rear yards6, and lot coverage is capped at 30 percent8. In the AG rural-residential district, lots need 1 acre and 150 feet of width7, with 50 feet front and rear yards and 15 feet side yards9 and 20 percent lot coverage10. Both districts cap height at 35 feet1112.

We could not confirm Desloge's rules on RV living, tiny homes, manufactured homes, accessory dwellings or minimum house size; ask the Building Department before you plan around any of them2.

Do you need a building permit in Desloge, and who issues it?

Yes for most construction. The City of Desloge Building Department reviews plans, issues permits and conducts inspections under the city's building codes2. Permits are required for new building construction, additions, changing the use of an existing building, fencing, pools, and mechanical, electrical or plumbing systems2. The city lists Chapter 500 as its building code13.

The department's page publishes a fee schedule and says an applicant completes a permit application, supplies a plot plan and pays the fees2. We could not confirm an owner-builder exemption inside the city.

St. Francois County's own page says new development in the county needs a county building permit from the County Clerk's Office14. That page does not say whether the requirement also covers addresses inside Desloge, so ask both the city and the clerk.

How do septic permits work inside Desloge?

Septic is tightly limited. Any use with a septic system must sit on a lot of at least 3 acres and have the necessary approvals from the Missouri Department of Natural Resources3. Smaller lots are expected to connect to public sewer and water, since new R-1 development is meant to be located where they are provided15.

The St. Francois County Health Center's Environmental Health Department issues OWTS construction permits and requires an application, a design plan and a soil morphology4. Missouri also lets some incorporated cities fall outside the local permitting authority, in which case the state health department handles the permit16. We could not confirm which applies in Desloge, so call the Health Center first.

Building a home in Desloge: the steps, in order

  1. Confirm the lot's zoning district and whether public sewer and water reach it115.
  2. If the lot would need septic, confirm it has at least 3 acres3 and contact the County Health Center4.
  3. Apply to the Desloge Building Department with a permit application and plot plan2.
  4. Check the county floodplain map before you buy; the county's Floodplain Manager can show whether the lot is in a regulated floodplain17.
  5. For a driveway onto a state highway, MoDOT requires a permit18.

What stays with St. Francois County, and what to check before you buy

For land outside city limits, use the St. Francois County page; Desloge's zoning does not follow you there. Septic permits come from the county health center16, and Missouri lets landowners install their own well or pump without a permit under state law19. We could not confirm whether Desloge adds its own well rules.

If a lot is in a regulated floodplain, the county requires a Floodplain Development Permit, and new construction must be elevated at least 1 foot above the Base Flood Elevation17. We could not confirm the city's own floodplain rules.

  • We could not confirm Desloge's rules on RVs, tiny homes, manufactured homes, accessory dwellings or minimum house size; call the Building Department2.
  • The city's building page lists 2006 ICC code editions, so confirm with the department which edition applies to your plans2.
  • County septic application fees were temporarily suspended effective August 28, 202620.
