#13 of 115 in Missouri

Unincorporated Crawford County, Missouri has no county building-codes program, so ordinary construction does not need a county building permit1. Septic permits come from the Crawford County Health Department under the county's own ordinance2. Cuba and Bourbon set their own zoning inside city limits34. Floodplain permits and MoDOT driveway permits can still apply56.

Do you need a building permit in Crawford County, Missouri?

Unincorporated Crawford County does not have a building-codes program that requires a permit for ordinary construction71. Missouri law fits that pattern: only counties of the first and second classification can adopt a building-permit program under RSMo 64.170, and a county that had not adopted one before August 28, 2001 needs voter approval to start13. A floodplain development permit can still be required for construction, renovation or improvement in a mapped floodplain, including rehab work on a flooded home1. Missouri also exempts farm buildings used for agriculture in unincorporated areas outside the mapped flood hazard area from county building-code powers, though that does not waive other state or federal rules14. Inside Cuba, the city requires a building permit for fences and walls; the county answer above covers only unincorporated land15.

Who handles county administration and floodplain permits in Crawford County, and how do you reach them?

Crawford County has no planning, zoning or building department; the closest thing to a general land-use contact is the Crawford County Commission at the Crawford County Courthouse, 302 W. Main St., #AS, Steelville, MO 65565, phone (573) 775-237616. The Commission is made up of a Presiding Commissioner elected countywide and two Associate Commissioners elected by district, and it represents the county on regional bodies including the Meramec Regional Planning Commission16. MRPC itself, at 4 Industrial Drive, St. James, MO 65559, phone 573-265-2993, administers Crawford County's floodplain management program and is the office to contact about a floodplain development permit17. A floodplain permit application goes to MRPC's administrator first and then to the County Commission for final approval before construction can begin17.

Does Crawford County have zoning?

No official source confirms that Crawford County has adopted countywide zoning for unincorporated land, and the county's own website lists no planning or zoning department8. Missouri lets a county adopt zoning under RSMo 64.845 to 64.880, but only after county voters approve it, so the statute alone does not show Crawford County holds that power18. Cities are different: Cuba zones its land by district, including an R-1 single- and two-family residential district3, and Bourbon publishes its own zoning regulations4. We found no minimum lot size, setback, lot-coverage or building-height rule for unincorporated Crawford County, so treat those as unconfirmed and ask the County Commission before you design around a number16.

How do septic permits work in Crawford County?

The Crawford County Health Department is the local septic authority, and the county's Onsite Wastewater Ordinance may add requirements beyond Missouri's minimum construction standards2. A permit is generally required before installing or repairing an onsite wastewater system, and Missouri exempts some single-family residential lots; because the county has its own ordinance, the three-acre state exemption may not apply, so confirm with the Health Department before relying on it1920. Do not start work until the Health Department issues a permit or confirms an exemption21. State DHSS regulates single-family residential systems and domestic systems up to 3,000 gallons per day, while DNR covers larger systems and certain lagoons2. In some incorporated cities the local authority sends septic permitting back to DHSS, so confirm which office applies to your address2. A privy is not recognized as sewage disposal for a continuously occupied dwelling22. State septic application fees have been suspended since August 28, 20269.

Can you live in an RV or tiny home on your land in Crawford County?

Inside the City of Cuba, recreational vehicles may not be occupied as living quarters anywhere in the city limits12. That city rule does not apply automatically to unincorporated Crawford County, where we could not confirm a rule allowing or prohibiting long-term RV occupancy128. Tiny-home and manufactured-home occupancy also remain unconfirmed for unincorporated land, so ask the Crawford County Commission about the parcel before buying with plans to live in any of these structures16.

Building a home in Crawford County: the steps, in order

  1. Ask MRPC whether the parcel is in a mapped floodplain; if it is, obtain approval before building and provide the required elevation certificate afterward1.
  2. Confirm jurisdiction with the County Commission; ordinary construction on unincorporated land does not require a county building permit1.
  3. Ask the Health Department what the county septic ordinance requires, and obtain a construction permit or written confirmation of an exemption before work2123.
  4. Arrange water: landowners may install their own well or pump without a permit, but a non-restricted well installation permit is required to construct or repair a water well otherwise, and a contractor needs a restricted permit10.
  5. Submit an online request for each driveway built or modified within MoDOT right-of-way; plans, drainage analysis or a traffic study may also be required6.
  6. If the project disturbs one or more acres, Missouri's land-disturbance stormwater permit applies; register through MoGEM and apply electronically because paper applications are no longer processed2425.

What to check before you buy land in Crawford County

Only about 4% of Crawford County soils lack severe limitations for a conventional septic drain field, so make the Health Department's site and system requirements an early contingency2623. Crawford County is 75.2% wooded, and 63.3% of its land has a slope of 15% or less, so inspect the actual building area, access route and clearing needs2728. Ask MRPC about floodplain status; project maps for applicable reviews may need to show the 100- and 500-year floodplains, stream buffers, flood-prone ground and erosion areas29. Missouri's land-disturbance stormwater permit for private projects costs $500 for 1 to under 5 disturbed acres, $600 for 5 to under 10, and $750 for 10 to 25; the separate area-wide permit is for governments only2430. For road access, distinguish MoDOT right-of-way from county-maintained roads because the MoDOT permit rule covers only its right-of-way, while a county-road driveway rule could not be confirmed31.

Watch-outs

  • Whether Crawford County has adopted countywide zoning for unincorporated land was not confirmed by any official source; the 'no zoning' finding here rests on the county's own office listing showing no planning or zoning department, not on a located ordinance8.
  • Minimum lot size, setbacks, lot coverage and building height for unincorporated Crawford County were not found in any official source; ask the County Commission before assuming none exist16.
  • The City of Cuba prohibits occupying an RV as living quarters inside city limits, while the rule for unincorporated Crawford County remains unconfirmed; verify the parcel's jurisdiction before relying on an RV for housing1216.
  • A driveway connection within MoDOT right-of-way needs a MoDOT permit, but we could not confirm a Crawford County permit process for access to county-maintained roads31.
  • Like most counties around it in Missouri, Crawford County does not require a county building permit7.

    • The floodplain permit application is sent to the county commission for approval; construction can begin once approved.
    • The administrator requires an elevation certificate after approval.
    • The source gives a specific floodplain example that basements may have to be foregone because no basements are allowed in a floodplain.
    • The source states that MRPC administers Crawford County's floodplain management program.
    “CRAWFORD COUNTY—Crawford County does not have a building codes program that requires a permit. However, you may need a floodplain development permit if you are planning construction, renovations or improvements to a structure located in a floodplain within Crawford County.

  • Who permits septicCounty

    Onsite wastewater permitting in Crawford County, Missouri, subject to incorporated-area exceptions and system-type jurisdictional limits.

    • The Crawford County Health Department is identified as the local authority for the county's ordinance-based OWTS permitting.
