Building permits, zoning and land rules in Titus County, Texas

Titus County does not require prior county approval or a building permit for a single-family home on unincorporated land^1,2. The county's Environmental Inspection Service handles OSSF permits and facility inspections rather than general building permits^4,8. Texas requires staged residential-code inspections only in a county that adopts the state framework, and we could not confirm that Titus County has done so; ask the County Judge's Office before construction^2,9. State rules still apply to industrialized housing and buildings, and an owner installing an industrialized unit for personal use may need an installation permit^10,11. City limits change the answer: Talco and Winfield enforce building codes, while Miller's Cove has no building codes in place³.

Titus County has no general county building-permit office for a single-family home on unincorporated land¹. Septic permits go through the Titus County Environmental Inspection Service, the county's designated OSSF authority^4,8. A subdivision or development plat outside municipal limits goes to the Commissioners' Court, and the published process requires an application, original plats, a paper copy, tax certificates and supporting materials⁴. The County Judge's Office is the practical contact for Commissioners' Court questions, while the County Clerk's Office records an approved plat^9,12. The subdivision checklist lists a $121 filing fee, but another county fee page gives a different amount, so confirm the current charge with the clerk^4,12. A new or changed driveway connecting to a state highway requires a separate TxDOT permit⁷.

Ordinary unincorporated land in Titus County has no county zoning that sets minimum dwelling size, setbacks, lot coverage, building height or permitted uses^3,5. Titus County's own plan lists no code of ordinances or comprehensive plan, and subdivision, septic, floodplain and deed-restriction rules are separate from zoning³. Local rules vary by municipality: Talco has a zoning ordinance, and Winfield has zoning ordinances³. The available county plan does not provide those cities' districts, setbacks or approval procedures, so obtain the applicable city rules before planning an RV, tiny home or other use³. Talco and Winfield also enforce building codes³. Miller's Cove has no building codes in place and no current code of ordinances or comprehensive plan, but that does not answer every utility or land-use question there³. On unincorporated land, a new single-family subdivision using individual OSSFs generally needs at least 1 acre of usable land per lot⁴.

A permit and approved plan are required to construct, install, alter, extend, repair or operate an OSSF, including a septic system or holding tank, unless a stated exemption applies⁶. Titus County's Environmental Inspection Service administers the local OSSF program, performs facility inspections and responds to complaints; ask the office what inspections to schedule and what local fee applies^4,8. The published TCEQ fee schedule is for areas without a local authorized agent, so it does not establish Titus County's charge^4,13. A tract of at least 10 acres may qualify for an exemption only when every condition is met, including a licensed site evaluation, one single-family dwelling, on-property effluent disposal, no nuisance or groundwater pollution, and every part of the system at least 100 feet from a property line⁶. OSSF-served developments must submit planning materials including a 100-year floodplain map and comprehensive drainage plan before individual OSSF permitting begins; the authority must decide in writing within 45 days⁴.

Titus County does not use county zoning to restrict RV occupancy, tiny-home occupancy, manufactured homes, accessory dwellings or temporary camping on ordinary unincorporated land⁵. Sanitation is separate: using a septic system or holding tank requires an approved OSSF permit unless every condition of an exemption is satisfied⁶. Creating a new lot can also trigger subdivision approval, and an OSSF-served single-family subdivision generally needs at least 1 acre of usable property per lot⁴. Inside Talco or Winfield, do not rely on the unincorporated-county answer because both cities have zoning and enforced building codes³. We could not confirm city-specific RV or tiny-home standards, so ask the relevant city before buying or moving a unit there.

1. Confirm whether the parcel is unincorporated or inside a city; Talco and Winfield have municipal zoning and enforced building codes³.
2. If you are dividing land outside municipal limits, take the plat through the Titus County Commissioners' Court process before selling or developing lots⁴.
3. For an OSSF-served development, prepare the required floodplain map, drainage plan and other planning materials before individual septic permitting begins⁴.
4. Apply through the Environmental Inspection Service for the OSSF permit and ask which inspections to schedule and what local fee applies; confirm before relying on any exemption^4,6,8.
5. Confirm access: a driveway onto a state highway requires Form 1058 and a fully executed TxDOT permit before right-of-way work begins⁷.
6. File the approved plat through the County Clerk's Office when subdivision rules apply; the checklist says $121, but confirm the current fee because county sources conflict^4,12.

Only 5.3% of Titus County soils have no severe limits for a conventional septic drain field, so obtain a site evaluation before pricing the wastewater system¹⁴. About 40.1% of the county is wooded and 92.6% of its land has a slope of 15% or less, but parcel-level soils, drainage and clearing costs still matter¹⁴. The nearest city of 100,000 or more is about 65 miles from the county center, and county population density is about 77.2 people per square mile¹⁴. Before closing, verify whether the tract is inside city limits, whether a division of land was properly platted, whether the planned OSSF fits, and whether access is from a state highway^4,6,7. We could not confirm a countywide private-well permit rule, so ask the County Judge's Office which authority applies to the parcel⁹.
