Do you need a building permit in Clarksburg, MO?

We could not confirm whether Clarksburg requires a general building permit for a conventional house, additions or outbuildings. Ask the Board of Aldermen to identify the required application, construction standards and inspections for your project before work begins.

Clarksburg does require a valid Board of Aldermen permit to locate or occupy a mobile home, except for mobile homes located in the city as of August 2, 2002.1 The mobile-home placement permit costs $25 and does not require renewal.1 That specific approval is the confirmed city construction-related process here; do not assume the same application answers your conventional-house question.

Does Clarksburg have zoning, lot-size rules or setbacks?

We could not confirm adopted Clarksburg zoning districts, a minimum residential lot size, general building setbacks or a minimum dwelling size. Ask the Board of Aldermen for the rules applicable to the exact parcel and proposed dwelling before committing to a site plan.

Clarksburg mobile homes must be separated from public streets and adjoining lots by at least 30 feet.1 The mobile-home applicant must also certify municipal water and sewer connection, or connection within 30 days of installation, along with tie-down, skirting and specified foundation preparation.1 Use those requirements for a mobile-home proposal; ask the city separately about dimensions for other types of buildings.

How do sewer connections and septic permits work in Clarksburg?

Clarksburg buildings and dwellings, including mobile homes, must connect to municipal sewage service when service is available.2 A new sewer connection needs prior Board of Aldermen approval, payment of the $100 tapping fee and a city inspection before the trench is filled.2 The patron maintains the service line from the main to the property.2

Where municipal sewage service is unavailable, Clarksburg requires a treatment system complying with Missouri Department of Health recommendations, without offensive odors or sewage effluent reaching adjoining property.6 DHSS handles septic permitting in Moniteau County; the Health Center page gives a DHSS contact route at 573-796-3412, option 5.7 Most onsite wastewater installations or repairs require a septic construction permit; any claimed residential-lot exemption needs confirmation before work starts.8 Missouri temporarily suspended OWTS application fees effective August 28, 2026; confirm the current charge with DHSS when applying.9

Can you live in an RV, tiny home or mobile home in Clarksburg?

We could not confirm Clarksburg rules for residential RV occupancy, temporary camping, tiny homes or accessory dwellings. Ask the Board of Aldermen to classify the proposed unit and approve the intended use before buying or moving it onto the parcel.

Clarksburg has a confirmed mobile-home placement process: submit the application and fee to the Board of Aldermen, which acts by majority vote to direct issuance.10 If the Board does not order a permit, the application fee is refunded.10 A mobile-home parcel may not have delinquent property taxes, and mobile-home parks need a separate annual license with additional requirements.1 Do not use the mobile-home approval as an answer to the unresolved RV or tiny-home occupancy question.

Building a home in Clarksburg: what are the steps in order?

  1. Ask the Clarksburg Board of Aldermen to confirm general building-permit, zoning, inspection and occupancy requirements for the proposed parcel and home. For a mobile home, submit the city placement application and fee to the Board.10
  2. Establish whether municipal sewer service is available; arrange Board approval and the tapping fee for a new connection where service is available.2
  3. If onsite wastewater is needed, contact DHSS through the Moniteau County Health Center and obtain a septic construction permit or confirmed exemption before installation.74
  4. Arrange the city sewer-connection inspection before backfilling the trench.2 For a mobile home, plan the required utility connection, foundation preparation, tie-down and skirting as part of placement.1

What should you check before buying land in Clarksburg?

For land outside city limits, use the Moniteau County guide for the county building-permit answer rather than carrying that answer into Clarksburg.11 Inside Clarksburg, confirm sewer availability early because the city requires connection when service is available.2

Moniteau County has only 0.2% of soils rated not limited for a conventional septic drain field; this county-wide figure calls for a parcel-specific site evaluation and may point toward an engineered system, rather than making septic impossible.12 Private domestic wells do not need a well permit, but Missouri well-construction rules and certification reporting still apply.5 Work on a driveway in MoDOT right-of-way requires a MoDOT permit.13 Ask the city to identify the applicable floodplain office and any city-street access approval before finalizing the purchase.

Watch-outs

  • We could not confirm general Clarksburg building permits, zoning or RV and tiny-home occupancy rules; ask the Board of Aldermen before buying for those uses. Clarksburg does have a separate mobile-home placement permit.1
  • Clarksburg mobile-home applicants must certify municipal water and sewer connection; ask the Board how that condition applies if service is unavailable before planning onsite wastewater.12
  • Missouri requires a floodplain development permit for covered development; we could not confirm the Clarksburg floodplain administrator or local ordinance.14

Unanswered questions are usually a sign that Clarksburg publishes no rule on the point, not that none exists. Moniteau County’s page lists the county offices to call.
