Building permits, zoning and land rules in Howell County, Missouri

Probably not in unincorporated Howell County: the county's website lists only elected offices, such as the Commission, Clerk, Assessor, Collector, Sheriff and Recorder, with no building department to issue a permit¹. We could not confirm a written county rule either way, so ask the County Commission if you are unsure. 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 cutoff⁸. 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 acres⁷.

The Howell County Health Department's Environmental Public Health division is the office to contact, since we found no Howell County building or zoning department⁴. The Missouri health department lists the Howell County Health Department as the contract authority for onsite wastewater permits; the state Department of Natural Resources regulates certain other systems, including those over 3,000 gallons per day⁹. The Health Department also serves the City of West Plains, so septic goes through the same office whether or not the parcel is inside the city⁴. It administers septic permitting under Missouri state law and regulations, and it also handles sewage-treatment complaints and inspections⁴. 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 apply⁴.

Apparently not in unincorporated areas: Howell County's government website shows no planning or zoning department, consistent with no countywide zoning outside its cities¹. 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 approval². 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 so¹⁰. Two statewide protections apply 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 structure⁶, and Missouri's county building and land-use restrictions do not apply to raising crops, livestock, orchards or forestry in unincorporated areas¹¹.

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 personally⁴. 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 Department⁴. About 32% of Howell County's soils are rated free of severe limits for a conventional septic drain field, so get the required soil test before choosing a system design^4,12. The Howell County Health Department handles sewage-treatment complaints and inspections, but the available rules do not establish universal periodic inspections for every septic system⁴. For a real-estate transfer, local health agencies generally no longer inspect existing systems; a buyer can use a licensed private inspector instead⁴.

Long-term RV occupancy, temporary camping, and tiny-home occupancy on private land remain unconfirmed in Howell County. Unincorporated Howell County appears to have no countywide zoning, but that does not by itself answer whether a particular RV or tiny-home use is lawful¹. Septic rules still apply to off-grid homes: a single-family residence on 3 or more acres may install a septic system without an installation permit, but it must use a registered installer unless the homeowner completes the entire installation⁴. Smaller residential tracts, businesses, and major repairs or modifications require a septic permit⁴. Howell County's available rules do not address composting toilets, incinerating toilets, graywater systems, or other non-septic sanitation methods, so ask the Howell County Health Department before relying on one⁴.

1. 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 guide².
2. We found no county building permit for ordinary construction, so after confirming your parcel is unincorporated, ask the County Commission to confirm that, then move to site and septic planning¹.
3. 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 begins⁷.
4. 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 yourself⁴.
5. 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 permit⁵.
6. 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-way¹³.

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 work¹². 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 bids⁵. Access: a driveway onto a state highway needs a MoDOT permit, and you must call Missouri One Call before digging once it is issued¹³. Grading: if site work will disturb an acre or more, budget for a land-disturbance permit fee starting at $500⁷. Drought: Howell County has spent about 5.2% of recent years in severe drought, so water supply is less of a worry than in drier counties¹². Taxes: the effective property tax rate runs about 0.6%, with a median annual bill near $892¹².
