Building permits, zoning and land rules in Texas County, Missouri
81Index Score / 100 #1 of 115 in Missouri
Texas County, Missouri is classified as not requiring a county residential building permit, but no available county page expressly confirms that rule, so verify an unincorporated parcel with the County Clerk before building1. County zoning is likewise listed as absent but not expressly confirmed; Houston has its own city zoning, and most onsite wastewater work requires a construction permit234.

Do you need a building permit in Texas County, Missouri?
Texas County is classified as not requiring a residential building permit because the Missouri county building-code dataset shows no adopted residential, commercial or energy code for the county1. The cautious answer is still to confirm before construction: the available county pages do not expressly say that Texas County issues no building permits, inspections or certificates of occupancy1. Missouri does not impose one uniform statewide building code; qualifying counties adopt codes locally, and voter approval may be required where a county had not adopted one before 20018. This county-level answer applies only to unincorporated land. A property inside a city can face municipal rules; Houston has a zoning ordinance governing construction, alterations, moving, repair and use within the city jurisdiction3. Call the Texas County Clerk with the parcel location before relying on the county classification9.
Who handles Texas County building and permit questions?
Texas County does not identify a dedicated building department in the available county directory, so the practical first call is the Texas County Clerk at 210 N Grand Ave, Suite 311, Houston, MO 65483, 417-967-21129. Give the Clerk the parcel number or road address and ask whether the land is unincorporated and whether county building, floodplain or subdivision review applies. The Texas County Health Department is the separate contact for onsite sewage questions at 950 N. Hwy 63, Houston, MO 65483, 417-967-413110. If the parcel lies inside Houston, contact the city because Houston's zoning code governs land and structures within the city jurisdiction and provides for conditional-use and variance applications3. A driveway built or modified within Missouri Department of Transportation right-of-way requires a MoDOT permit rather than a county building permit11.
Does Texas County have zoning?
Texas County appears to have no county zoning, but the county directory lists a Planning Commission without expressly stating that no zoning order exists2. Treat setbacks, minimum lot size, minimum dwelling size, building height and subdivision approval as questions for the County Clerk, not confirmed freedoms9. Missouri law allows some counties to establish zoning for unincorporated territory after voter approval, but that statewide authority does not prove whether Texas County adopted a zoning order12. Jurisdiction matters. Houston has an adopted zoning ordinance within its city jurisdiction, including an official zoning map and procedures for conditional uses and variances3. Farm structures have conditional state protections, but those protections do not create a blanket exemption from septic, floodplain, zoning or every other land-use requirement13.
How do septic permits work in Texas County?
Missouri requires a construction permit before installing or repairing most onsite wastewater systems, while some single-family residential lots may qualify for an exemption4. The Texas County Health Department handles local onsite sewage permits and describes an exemption for a single-family residence on at least 3 acres unless a Notice of Violation has been issued5. The department says the acreage exemption can end after a Notice of Violation until a proper system is installed, and gives separate acreage and separation conditions for additional residences10. Ask the department to confirm eligibility before excavation. Only 9.1% of Texas County soils lack severe limitations for a conventional drain field, so obtain a site evaluation before choosing a house site7. Untreated domestic sewage cannot simply be discharged as an off-grid alternative; buildings where people live, work or assemble must have sanitary disposal through a compliant system14.
Can you live in an RV or tiny home in Texas County?
We could not confirm a Texas County rule that allows, limits or prohibits long-term RV occupancy, temporary camping or tiny-home occupancy on private land. Texas County appears to have no county zoning, but the county directory does not expressly confirm that no zoning order exists2. Do not translate that gap into a right to live permanently in an RV or place a tiny home without review. Ask the Texas County Clerk whether the Planning Commission, a county order or the parcel's location creates any occupancy, setback, subdivision or floodplain condition9. If the parcel is inside Houston, the city's zoning ordinance applies within the city jurisdiction3. Whatever the dwelling type, domestic wastewater needs sanitary disposal through a compliant sewer or onsite system14. Minimum home size, manufactured-home placement and accessory dwellings also remain unconfirmed.
Building a home in Texas County: the steps in order
Ask the Texas County Clerk to confirm whether the parcel is unincorporated and whether county planning, subdivision or floodplain review applies9.
If the property is inside Houston, take the site plan to the city because Houston has its own zoning ordinance3.
Evaluate soils before fixing the house location; only 9.1% of county soils lack severe limitations for a conventional drain field7.
Confirm the septic-permit or exemption path with the Texas County Health Department before work510.
For a driveway in MoDOT right-of-way, submit the required state access request11.
If drilling a well, use a permitted contractor or confirm that the narrow landowner exemption for the owner's permanent residence or farm applies6.
Confirm the county building-permit classification with the Clerk because no explicit county statement was located19.
What should you check before buying land in Texas County?
Make septic feasibility a purchase contingency: only 9.1% of Texas County soils lack severe limitations for conventional drain fields7. Determine whether a proposed driveway enters MoDOT right-of-way, where construction or modification requires a state permit11. Ask the County Clerk whether the parcel is unincorporated and whether subdivision or floodplain review applies9. Terrain and clearing affect cost: 72.3% of the county is at a slope of 15% or less, while 58.4% is wooded1516. A private well must follow Missouri construction rules even when the owner qualifies for the limited contractor-permit exemption6. For budgeting, the effective property-tax rate is about 0.5%, the median annual bill about $652, and the typical home value about $208,770171819. Verify every intended use because RV, tiny-home, manufactured-home, accessory-dwelling and short-term-rental rules remain unconfirmed.
Watch-outs
Texas County's building-permit classification is 'not required,' but no county page expressly confirms the absence of permits, inspections or certificates of occupancy; verify the parcel with the County Clerk19.
The county zoning classification is not a substitute for a jurisdiction check: Houston has its own zoning ordinance23.
An acreage-based septic exemption does not solve a poor-soil site; only 9.1% of county soils lack severe limitations for a conventional drain field57.

What the ordinances and state agencies actually say — one answer per question, each quoted from the official source and independently re-checked.
Texas County rules
Building permitNot required
State of Missouri county building-code dataset lists no energy, residential, or commercial building code adopted for Texas County; Missouri non-charter rural counties generally cannot require building permits. Corroborated by the state County Building Codes dataset (data.mo.gov iq7s-izvt, 2021): no county residential building code adopted.
County board/office directory shows only a Planning Commission with no zoning department, zoning board, or zoning administrator, consistent with no adopted county zoning.
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 authority under RSMo 64.170 applies to counties of the first and second classification.
A county that had not adopted a building code before August 28, 2001 must obtain voter approval before adopting under RSMo 64.170 to 64.200.
The adoption vote is limited to voters in the affected area; a code affecting a county is not voted on by citizens of incorporated territory.
A county adopting under RSMo 64.180 must use a current nationally recognized building code edition from calendar year 1999 or later, as amended.
A county building ordinance may not conflict with liquefied petroleum gas installation requirements governed by RSMo 323.020.
A community may incorporate a code by reference only if it otherwise has legal power to adopt the ordinance.
A code incorporated by reference must be filed with the community clerk and available for public inspection for 90 days before adoption.
An ordinance adopting a code by reference must state the penalty separately rather than incorporate the penalty by reference.
RSMo 67.280 defines community to include any county, fire protection district, or municipality, and municipality to include an incorporated city, town, or village.
“Because fire and building codes are adopted at the local level in Missouri”
Who permits septicMixed
Missouri wastewater treatment systems, including domestic onsite systems, larger-flow systems, direct discharges, lagoons, subdivisions, and industrial wastewater.
DNR regulates direct point-discharge or surface-land-application systems, non-individual lagoons, facilities exceeding 3,000 gallons per day, and industrial process waste.
DHSS or a local agency, typically the county health department, regulates single-family subsurface onsite systems, individual single-family lagoons, and qualifying systems at or below 3,000 gallons per day.
Local agencies may administer qualifying systems under local authority or ordinance.
domestic wastewater flow threshold: <= 3000 gallons per day (DNR regulates facilities with domestic wastewater flow greater than 3,000 gallons per day)
“In Missouri, different state and local agencies are responsible for regulating wastewater treatment systems.”
Septic permitRequired
Installing or repairing most onsite wastewater treatment systems in Missouri, including residential systems subject to state permitting.
A construction permit is required before installing or repairing most OWTS.
Some single-family residential lots may be exempt.
For residential property less than three acres, a permit is required; the exemption does not apply in some counties, so the county authority must be checked.
Work should not begin until a permit is issued or an exemption is confirmed.
Effective August 28, 2026, application fees for onsite sewage disposal system construction, modifications, and repairs are temporarily suspended.
residential lot threshold: < 3 acres (The exemption does not apply in some counties.) · temporary permit-fee suspension effective date: 2026-08-28 (Applies to application fees associated with onsite sewage disposal system construction, modifications, and repairs.)
“A construction permit is required before installing or repairing most onsite wastewater treatment systems (OWTS). Some single family residential lots may be exempt from permitting.”

For systems constructed, modified, or repaired by persons not registered under sections 701.053 to 701.055, inspection is required in the aggregate for at least 75 percent of systems.
The 75-percent category applies to systems for which notice of construction, repair, or modification is given under sections 701.046 to 701.048 and 701.050.
The statute establishes aggregate inspection percentages, not inspection of every individual system.
The statute is effective August 28, 1994.
aggregate inspection percentage for systems built by registered contractors: <= 60 percent (systems constructed, modified, or repaired by contractors registered under sections 701.053 to 701.055) · aggregate inspection percentage for systems built by unregistered persons with required notice: >= 75 percent (systems for which notice is given under sections 701.046 to 701.048 and 701.050)
“A city, county or the department shall inspect, in the aggregate, up to sixty percent [...] and at least seventy-five percent”

Prohibited — Domestic sewage and wastewater disposal in Texas County outside a regulated sewer system or compliant onsite sewage disposal system, including untreated discharge that creates a health hazard, pollution, groundwater contamination, or nuisance.
“Property owners of all buildings where people live, work or assemble shall provide for the sanitary disposal of all domestic sewage.”
Well permitLimited
Well construction, alteration, major repair, abandonment, and related well installation work in Texas County, Missouri.
A person engaging in business as a well installation contractor must obtain a permit from the Missouri Division of Geology, Land Survey and Water Resources.
A person constructing a well on the person's own or leased property for only a single-family permanent residence, or only farming on the person's farm, may do so without obtaining the contractor permit, but must comply with applicable well-construction rules.
The landowner exemption does not apply where the water is intended for public use or for use in any residence other than the person's own.
A primary well installation contractor or pump installation contractor must obtain a permit and comply with applicable rules.
A water system exclusively serving a charitable or benevolent organization may be exempt from well-construction rules if it does not regularly serve an average of 100 or more persons at least 60 days per year and does not serve a school or day-care facility, subject to the multifamily-well exception and a groundwater/public-health-threat exception.
The charitable-or-benevolent-organization exemption does not eliminate rules under sections 256.600 to 256.640 that apply to multifamily wells.
The Water Well Drillers' Act provisions cited are effective August 28, 1991; the charitable-or-benevolent-organization exemption is effective August 28, 2011.

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.
A first-class noncharter county or a county of the second, third, or fourth class may establish county zoning under RSMo §§ 64.845 to 64.880 only after the zoning question is submitted to county voters and a majority of votes cast favors county zoning.
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”
county building authorityLimited
County regulation of construction and issuance of building permits for buildings, including residential construction, in Missouri counties, with the practical focus on county-controlled areas outside incorporated territory.
RSMo § 64.170 grants the authority to counties of the first and second classification only.
The authority is subject to subsections 2 and 3.
A county that had not adopted a building code before August 28, 2001, under §§ 64.170 to 64.200, lacks authority to adopt one under those sections unless voters approve it.
The building-code authority vote is limited to voters in the affected area; a code affecting a county may not be voted on by citizens of incorporated territory.
The statute authorizes building regulations, building permits, inspections, licensing rules, and permit, license, and inspection fees.
“the county commission in all counties of the first and second classification [...] is for this purpose empowered [...] to adopt [...] regulations to control the construction”
