Do you need a building permit in Pulaski County, Missouri?
An ordinary home in unincorporated Pulaski County does not require a county building permit1. Call the County Clerk & Commission before construction for parcel-specific confirmation, especially if a lender, insurer or contractor needs written verification12. Inside Dixon, construction requires a city building permit from City Hall before work begins8. Missouri DHSS remains the countywide onsite wastewater authority, and Dixon also requires a city permit for private sewage disposal systems49. A farm-building exemption in state law concerns county fire-protection and fire-prevention ordinances; it is not a blanket exemption from septic, floodplain, zoning or other land-use requirements10.
Who handles Pulaski County building permits and land-use questions?
Pulaski County has no confirmed building-permit office for unincorporated residential construction, so the Pulaski County Clerk & Commission is the practical first contact for parcel-specific building, zoning and land-use questions12. Reach the office at 573-774-4701 or pcmoclerk@gmail.com, or visit 301 Historic Rt. 66 E. in Waynesville2. Ask whether the parcel lies inside an incorporated municipality, because Missouri building and fire codes are adopted locally and a city may have its own requirements11. We could not confirm Pulaski County requirements for a certificate of occupancy, county-road access or floodplain development; ask the County Clerk & Commission which office handles each issue2. A driveway constructed or modified within MoDOT right-of-way requires a state permit12. MoDOT accepts right-of-way applications online, through the area Traffic Specialist or by mail, and the Traffic Specialist must be contacted at least 48 hours before work begins13.
Does Pulaski County, Missouri have zoning?
Pulaski County's countywide zoning status could not be confirmed from an official county or state source3. Do not treat the absence of a confirmed zoning office as proof that an unincorporated parcel has no zoning, setbacks, minimum lot size, minimum dwelling size, height limit or lot-coverage rule3. Ask the County Clerk & Commission to identify any county ordinance affecting the parcel and to confirm whether the address is inside municipal limits2. The county guidance here concerns unincorporated land; inside St. Robert, the city sets zoning and requires land uses to conform to its zoning and land-development regulations1415. Missouri DHSS remains the onsite wastewater authority within Pulaski County, including city addresses4. Additional county subdivision rules and rules for accessory dwellings, manufactured homes and short-term rentals remain unconfirmed; ask the County Clerk & Commission about the intended use2.
How do septic permits work in Pulaski County?
Missouri DHSS is the current onsite wastewater authority for Pulaski County4. A construction permit is required to install or repair a system on residential property under 3 acres; nonresidential systems require a permit regardless of acreage16. Some single-family lots may qualify for an exemption, but acreage alone does not establish eligibility; wait for DHSS to issue a permit or confirm an exemption before work begins175. Contact the DHSS Onsite Wastewater Treatment Program at 573-751-6095 or OnsiteProgram@health.mo.gov18. Application fees have been temporarily suspended since August 28, 2026, while DHSS develops new fee standards19. DNR approval is required for subdivisions, mobile-home parks and campgrounds planning onsite wastewater systems; owners in unapproved developments should contact DNR about residential housing-unit requirements20. DNR also regulates systems discharging to surface water, non-single-family lagoons, industrial wastewater and systems over 3,000 gallons per day21. Only about 9% of Pulaski County soils avoid severe limits for a conventional drain field, so arrange a site and soil evaluation before fixing the house location or septic budget22.
Can you live in an RV or tiny home in Pulaski County?
We could not confirm Pulaski County rules for long-term RV occupancy, temporary camping or tiny-home occupancy; ask the County Clerk & Commission about the proposed use2. Countywide zoning also remains unconfirmed, so the lack of a published rule is not permission to occupy an RV or tiny home on an unincorporated parcel3. An off-grid setup may use a compliant onsite sewage system instead of a regulated sewer connection, but every occupied building must provide sanitary sewage disposal and the onsite system must follow Missouri rules2324. Residential property under 3 acres needs a construction permit for septic installation or repair, and nonresidential systems need one regardless of acreage; wait for a permit or confirmed exemption before work1721. For a tiny home inside a city, contact that municipality because Missouri building codes are adopted locally11.
Building a home in Pulaski County: what are the steps?
- Ask the County Clerk & Commission to confirm that the parcel is in unincorporated Pulaski County and to identify any zoning, floodplain, access or subdivision rule tied to it23.
- Obtain a site and soil evaluation early because only about 9% of county soils avoid severe limits for a conventional drain field22.
- Contact Missouri DHSS before septic work; DHSS must issue a permit or confirm an exemption before installation or repair begins25518.
- If the project is a subdivision, mobile-home park or campground using OWTS, obtain DNR approval as well; owners in unapproved developments should contact DNR about residential housing-unit requirements20.
- Determine who controls the road. Construction or modification of a driveway in MoDOT right-of-way requires a state permit12.
What should you check before buying land in Pulaski County?
Start with septic feasibility: only about 9% of Pulaski County soils avoid severe limitations for a conventional drain field, so a soil evaluation can change the usable building area and system cost22. About 59.7% of the county is at a slope of 15% or less, and about 72% is wooded, making an on-site review of grade, clearing and access more useful than county averages alone2627. Federal land covers about 28.9% of the county, so verify the surveyed parcel boundary and legal access rather than inferring them from nearby open land28. A parcel need not connect universally to public sewer, but every occupied building must dispose of sewage through a regulated sewer or a compliant onsite system23. County floodplain-development rules, private-well requirements and county-road driveway permits could not be confirmed; ask the County Clerk & Commission which office controls each issue for the parcel2. Missouri does not require an OWTS inspection for every sale, although a lender or buyer may request one from a licensed individual; ask DHSS whether Pulaski County has an additional local rule29. The effective property-tax rate is about 0.6%, with a median annual bill near $1,1593031.
Watch-outs
- An ordinary home in unincorporated Pulaski County does not require a county building permit; ask the County Clerk & Commission for parcel-specific confirmation before construction12.
- Pulaski County zoning, RV-occupancy, tiny-home, setback and minimum-size rules remain unconfirmed; ask the County Clerk & Commission before relying on an assumed allowance32.
- A larger residential lot does not automatically establish a septic-permit exemption in Pulaski County; wait for Missouri DHSS to confirm an exemption or issue a permit before installation or repair175.
- Do not confuse Pulaski County, Missouri with Pulaski County, Virginia; the Missouri county office is at 301 Historic Rt. 66 E. in Waynesville2.
