Building permits, zoning and land rules in Howell County, Missouri
78Index Score / 100 #11 of 115 in Missouri
Unincorporated Howell County, Missouri has no county building-permit requirement and no county zoning ordinance12. The county's official website lists only elected offices, with no building or planning department, unlike the City of West Plains inside the county, which has its own zoning and adopted building code23. Septic systems still go through the Howell County Health Department, which permits systems under Missouri law4.
No county zoning; the City of West Plains zones its own limits2

Do you need a building permit in Howell County, Missouri?
No. Howell County's official website lists only constitutional offices, such as the Commission, Clerk, Assessor, Collector, Sheriff and Recorder, with no building department to issue a permit1. Missouri only gives building-code authority to counties of the first and second classification, and even a qualifying county needed voter approval to adopt one if it had not already done so before the state's 2001 cutoff9. That is different inside the City of West Plains, the county seat: West Plains has adopted the 2021 International Building Code and 2020 National Electrical Code by ordinance for construction within city limits3. One statewide permit can still apply outside any building-permit process: disturbing one or more acres of land, such as grading for a house pad or long driveway, requires a Missouri land-disturbance permit with a stormwater pollution prevention plan, and fees run from $500 for under 5 acres up to $5,000 for 500 or more acres8.
Who handles septic permits in Howell County?
The Howell County Health Department's Environmental Public Health division is the office to contact, since Howell County has no separate building or zoning department10. It administers septic permitting under Missouri state law and regulations, and it also handles sewage-treatment complaints and inspections11. Its listed application fee is $90, but Missouri's state health department has temporarily suspended application fees for onsite sewage disposal system construction, modifications and repairs effective August 28, 2026, so confirm the current fee directly with the department before you apply5.
Does Howell County have zoning?
No, not in unincorporated areas. Howell County's government website shows no planning or zoning department, consistent with no countywide zoning outside its cities2. Inside the City of West Plains, the opposite is true: the city has its own zoning districts and land-use requirements, and commercial or mixed-use development plans must go to the city's planning commission for approval12. Missouri counties can adopt zoning for their unincorporated territory, but only after voters approve it in a countywide referendum, and nothing in the official sources reviewed shows Howell County has done so13. One statewide protection applies regardless: no county fire-prevention or fire-protection ordinance in Missouri can require a permit for erecting, maintaining, repairing, altering or extending a farm building or farm structure7.
How do septic permits work in Howell County?
A single-family home on 3 or more acres does not need a permit to install its septic system, though state law still requires a registered septic installer unless the homeowner installs the entire system personally5. Systems on less than 3 acres, all business systems, and any major repair or modification to an existing system do require a permit from the Health Department5. About 32% of Howell County's soils are rated free of severe limits for a conventional septic drain field, so roughly two-thirds of parcels should expect extra site work, an engineered design, or an alternative system14. A soil test by a state-approved evaluator is required either way, and Missouri's health department no longer routinely inspects existing systems for real-estate transfers, so a buyer relying on system condition should hire a licensed private inspector15.
Can you live in an RV or tiny home on your land in Howell County?
This is genuinely unconfirmed rather than a clear yes or no: no official Howell County source addresses long-term RV occupancy, temporary camping, or tiny-home occupancy on private land. The county's lack of a zoning ordinance means there is no county zoning rule restricting it, but that absence has not been confirmed as a deliberate policy choice the way it has in counties with an explicit no-zoning-authority finding2. If you are considering a manufactured home instead, the official sources reviewed for this guide likewise do not establish Howell County's placement or occupancy conditions, so confirm directly with the county and any lender or insurer before you buy a home expecting to place one.
Building a home in Howell County: the steps, in order
Confirm your parcel is outside West Plains or another incorporated city; inside those limits you will need a municipal permit and must follow that city's own zoning and adopted codes instead of this county-level guide12.
Since there is no county building permit for ordinary construction, you can move directly to site and septic planning once you have confirmed your parcel is unincorporated1.
If your build will disturb one or more acres, register with the Missouri Gateway for Environmental Management and secure a land-disturbance permit with a stormwater pollution prevention plan before grading begins16.
Contact the Howell County Health Department to determine whether your septic system needs a permit; a single-family home on 3 or more acres can skip the permit but must still use a registered installer unless you install the system yourself10.
If you need a well, know that you can install your own well or pump without a permit, but hiring someone else to do it requires a permit6.
If your driveway will connect to a state highway, submit an online request to MoDOT for a driveway permit before starting any work in its right-of-way17.
What to check before you buy land in Howell County
Septic and soils: with about 32% of Howell County's soils free of severe limits for a conventional drain field, get a site-specific soil test before assuming a standard system will work14. Wells: you can drill and plumb your own well without a state permit, but any contractor you hire needs one, which is worth knowing when comparing bids6. Access: a driveway onto a state highway needs a MoDOT permit, and you must call Missouri One Call before digging once it is issued17. Grading: if site work will disturb an acre or more, budget for a land-disturbance permit fee starting at $5008. Drought: Howell County has spent about 5.2% of recent years in severe drought, relatively low for the region18. Taxes: the effective property tax rate runs about 0.6%, with a median annual bill near $892, both on the low end1920.
Watch-outs
Building inspections, certificates of occupancy, owner-builder exemptions, minimum dwelling or lot size, setbacks, lot coverage, building height, and subdivision rules are all unconfirmed for unincorporated Howell County in the official sources reviewed for this guide; the county's silence on these topics is not proof that no rule applies, so ask the Health Department or County Commission directly before you build10.
The Health Department's listed $90 septic application fee may not be current: Missouri's state health department temporarily suspended onsite sewage disposal application fees effective August 28, 2026, so confirm the fee when you apply5.

Building permitNot required
Howell County's official site lists only constitutional offices (Commission, Clerk, Assessor, etc.) with no building department, and Missouri non-charter rural counties generally cannot require residential building permits. Corroborated by the state County Building Codes dataset (data.mo.gov iq7s-izvt, 2021): no county residential building code adopted.
The county government website shows no planning or zoning department, consistent with no countywide zoning in unincorporated Howell County (city zoning applies inside municipalities like West Plains).
Missouri statewide legal framework for building-code adoption by counties and other communities; the statutes authorize local adoption rather than establishing one uniformly adopted statewide building code.

county zoning authorityGeneral
Missouri counties adopting zoning regulations for unincorporated territory.
First-class charter counties are empowered under RSMo § 64.090; that section excludes first-class counties without a charter form of government.

The authority applies to unincorporated portions or territory and does not apply to incorporated portions under § 64.090.
Section 64.090 excludes specified agricultural activities and certain farm structures, underground mining, and protects existing lawful uses subject to gradual elimination of nonconforming uses.
“If a majority of the votes cast is in favor of county zoning, the county commission shall proceed with a program of county zoning”
