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

Unincorporated Clinton County requires a building permit before building or altering a structure; county zoning approval and other site approvals remain separate requirements.1 Separate building permits are generally required for each structure, though accessory buildings and appurtenances may share the main-building permit.15 Building applications require scaled plans and a plot plan, and the Zoning Administrator must act by the fifth business day after filing.16 Apply in writing for the certificate of occupancy concurrently with the building-permit application; occupancy must wait for final wastewater inspection and Health Department approval of issuance.17

Clinton County's dwelling-construction fee is $0.30 per square foot, and applications filed after construction starts incur double the scheduled fee.18 We could not confirm an adopted model residential code, a general building-inspection schedule or an owner-builder exemption; ask Planning and Zoning which standards and inspections apply to your project.

Who issues building permits in Clinton County, Missouri?

Clinton County Planning and Zoning handles building permits, zoning questions and onsite wastewater application intake.19 The county zoning rules apply to unincorporated land.2 Inside Cameron, the city issues building permits and regulates zoning; Cameron's superintendent also issues private-sewage permits and handles inspections, while the county process routes wastewater review and inspections through the County Health Department.4563

Holt, which lies mainly in Clay County and reaches into Clinton County, issues its own building permits and sets zoning.2021 Holt requires a city private-sewage permit, and its code allows additional requirements from the Clay and Clinton County health officers.22 Ask Clinton County Planning and Zoning for the current county forms, fee calculation and parcel's mapped district.

Does Clinton County, Missouri have zoning?

Clinton County divides unincorporated land into agricultural, residential, commercial, recreation, industrial, special-use and flood-hazard districts; district boundaries follow the county zoning map as amended.23 Cameron, Plattsburg and Holt have city zoning; Holt lies mainly in Clay County and reaches into Clinton County.52421 Clinton County Planning and Zoning and the County Health Department administer the county wastewater process; Cameron has its own private-sewage permit and inspection process, and Holt requires a city permit while allowing additional county health requirements.25622

Agriculture District A requires at least 950 square feet of living floor area and 20 acres per family for a dwelling.910 Subdivision lots using septic tanks and laterals require at least 5 acres; publicly owned central-sewer lots may be as small as 10,000 square feet, subject to additional state and utility conditions.10 R-1 also requires 950 square feet of living floor area and prohibits trailers and mobile homes.26 Setbacks vary by district and lot size.27 R-1 primary structures are limited to 35 feet, subject to specified exceptions; Agriculture District A exempts farm buildings and structures from height limits.2829

How do septic permits and off-grid sanitation work in Clinton County?

Clinton County requires septic permits before onsite wastewater installation or repair; the Zoning Administrator issues the permit and the County Health Department reviews the design and performs inspections.3025 For a new installation, obtain morphology from a licensed soil evaluator and have a Missouri-licensed installer design and install the system.31 Submit the Applicant Contact Form and Onsite Wastewater Permit Application with the morphology and the published $235 licensing-and-inspection fee; design review and pre-inspection precede issuance, and the issued permit must be posted before construction.32

Clinton County septic final inspection requires at least 24 hours' notice; leave subsurface components uncovered or the inspection fails and the components must be uncovered.33 Off-grid septic and individual lagoons need county approval; the order specifies a minimum 1,250-gallon septic tank, and a holding pond is permitted only when soil morphology dictates it.3435 Missouri has temporarily suspended state-program wastewater application fees; ask Planning and Zoning whether that affects the published local charge.3631

Can you live in an RV, tiny home or manufactured home in Clinton County?

In unincorporated Clinton County, a vacation vehicle cannot be occupied for more than 29 consecutive days on the same parcel or another parcel within 1,000 feet unless there is a 29-day break or a Temporary Living Permit is obtained.13 Connecting a vacation vehicle to permanent onsite wastewater also requires a Temporary Living Permit.13 The separate C-2 transient-trailer-park rule limits parking to 72 hours; that park rule does not authorize permanent RV living on an individual parcel.37

We could not confirm tiny-home classification or occupancy; ask Planning and Zoning before buying or placing one. Manufactured homes must satisfy district requirements and building approvals, have at least 950 square feet excluding the hitch, and be anchored to a permanent foundation; skirting is required within 90 days unless a permanent perimeter enclosure is installed.11 Permanent and temporary manufactured-home uses require approved water, sewage disposal and utility connections.12 Mobile homes in the agricultural district require a hardship variance.38

What approvals come before building and occupying a Clinton County home?

  1. Confirm the parcel's district, allowed use and dimensional requirements with Planning and Zoning, then submit scaled plans and a plot plan.3916
  2. Obtain county-road driveway approval; the $50 application charge is waived when filed with a building-permit application.1440
  3. In mapped Zone A, obtain a separate development permit for new construction, substantial improvements or manufactured-home placement; floodplain inspections and a final as-built elevation certificate also apply.4142
  4. Complete wastewater review and pre-inspection, obtain and post the septic permit before installation, then arrange final inspection with subsurface components uncovered.3243
  5. Obtain the required certificate of occupancy before moving in; final wastewater inspection and County Health Department approval are prerequisites to issuance.17

What should you check before buying or dividing Clinton County land?

Verify the parcel's zoning-map designation, county-road access approval, flood exposure and wastewater feasibility before closing.391441 Clinton County requires Planning and Zoning Commission approval before a plat or subdivision of unincorporated land can be recorded.44 Preliminary plats must be submitted at least 10 days before the approval meeting, and subdivisions of more than 6 lots require Department of Natural Resources approval.45 Subdivisions of at least 25 lots require public water and central sewage; a separate wastewater provision requires mechanical treatment or an oxidation basin at 25 dwelling units.1246 Ask Planning and Zoning how both thresholds apply to the proposed division.

We could not confirm a separate county well-permit requirement. Missouri requires permits for regulated well and pump contractors, but allows landowners to install their own well or pump without a permit under the applicable law and rules.47

Watch-outs

  • Starting construction before applying doubles the scheduled county permit fee.18
  • Give the septic inspector at least 24 hours’ notice and leave subsurface components uncovered; covering them causes a failed inspection and requires uncovering.8
  • An RV stay longer than 29 consecutive days, or an RV connection to a permanent onsite wastewater system, requires a Temporary Living Permit in unincorporated Clinton County.13
  • Building or land occupancy must wait for the required certificate of occupancy and final wastewater approval; accessory agricultural uses have an exception.17
