Unincorporated Hunt County, Texas does not require a general building permit outside the Lake Tawakoni zoning area, and the county does not issue Certificates of Occupancy or require general building inspections12. Properties within 5,000 feet of the Sabine River Authority property at Lake Tawakoni are different: the zoning ordinance requires a building permit before a building is erected, altered or converted3. Septic systems require county review, subject to the order's stated jurisdictional exceptions4.

Do you need a building permit in Hunt County, Texas?
Outside the Lake Tawakoni zoning area, Hunt County does not administer a general building-permit program, issue Certificates of Occupancy or require general building inspections1211. Texas counties have building authority only in limited circumstances, including fire-code permits for specified buildings in qualifying counties and residential standards adopted by resolution in certain counties12. The Lake Tawakoni zoning area is the important local exception: before erecting, altering or converting a building or land there, the owner must obtain a permit from the Lake Tawakoni Planning Commission and comply with the ordinance3. Permitted commercial construction in that area requires a final inspection and final approval before occupancy13. Elsewhere, other county approvals still matter: a culvert permit applies to a new driveway requiring a culvert, a Development Permit applies when property contains floodplain, and an OSSF permit is generally required before septic installation14154.
Who handles permits, floodplain and septic in Hunt County?
Hunt County Development is the starting point for subdivision, culvert, floodplain and Lake Tawakoni zoning information16. Hunt County Development is at 2507 Lee Street, First Floor - Room 107, Greenville, TX 75401, and can be reached at (903) 408-4204 or [email protected]16. Culvert permits are available from the Commissioners' Office; after the owner stakes the proposed location and gives notice, a county representative inspects the marked location within 14 working days to determine the required size9. Property containing any amount of floodplain needs a Development Permit before receiving a 911 address or septic permit, and the county's permitting notice directs applicants to the Hunt County Health Department for that permit15. Septic applicants should contact the Health Department's Environmental Services office at 2701 Johnson St., Greenville, TX 75401, by phone at (903) 408-4140 or by email at [email protected]17.
Does Hunt County have zoning?
No, not across most of the county. There is no zoning in the unincorporated areas of Hunt County more than 5,000 feet from Lake Tawakoni, and the Hunt County Subdivision Regulations and Engineering Standards apply to all unincorporated property instead6. Texas law backs this up: county zoning power is granted only for specific geographic areas like Padre Island beaches in Cameron or Willacy County, military zones, and certain named lakes, and Hunt County isn't one of the counties with general zoning authority18. Lake Tawakoni is the exception: the Lake Tawakoni Zoning Ordinance applies to all properties within 5,000 feet of the Sabine River Authority property of the lake, administered through the Lake Tawakoni Planning Commission and Hunt County Commissioners Court19. Inside that zoned area, districts like the E-2 Estate Development District set real numbers: an 85,000-square-foot minimum lot, a 1,000-square-foot minimum floor area per dwelling, and accessory dwelling units allowed only for family members, placed at least 10 feet from side and rear property lines20. Outside that 5,000-foot Lake Tawakoni zone, the county sets no minimum home size, no minimum lot size, no setbacks and no building-height limit197.
How do septic permits work in Hunt County?
Hunt County generally requires an OSSF permit before septic installation, regardless of lot size, while recognizing the limited state-rule exemption identified in the county order4. The property owner or installer must apply before construction and provide the required planning materials, site evaluation, Texas-licensed survey, fee and recorded affidavit before authorization to construct4. A commercial installer must hold the proper current license, while an owner may install only with approval and a permit from the designated authority4. The installer must notify the designated representative at least five days before the system is ready for inspection, and aerobic systems carry maintenance requirements21. Within a city jurisdiction, the applicant needs a city letter stating that public or private sewer service cannot be provided before an OSSF may be permitted22. Holding tanks are generally prohibited but may be allowed by permit from the designated representative23. Only 0.5% of Hunt County soils lack severe limits for a conventional drain field, so arrange the site evaluation early10.
Can you live in an RV or tiny home on your land in Hunt County?
Outside the Lake Tawakoni zoning area, Hunt County's lack of zoning means the county does not impose zoning-based RV occupancy, tiny-home, minimum-home-size, minimum-lot-size or setback rules7. We could not confirm every non-zoning rule that might affect living in a single RV or tiny home, so ask Hunt County Development about the parcel and intended use before moving one onto the land16. Hunt County does regulate temporary rental communities: a rental community of three or more recreational vehicles or temporary rental structures used for stays under 180 days without renewal needs a development permit and infrastructure plan24. In the Lake Tawakoni E-2 Estate Development District, a temporary building, mobile home or travel trailer may be used as an on-site dwelling only while the main home is being built and must be removed within six months of construction starting or the building permit being issued20. That E-2 rule should not be assumed to describe every Lake Tawakoni zoning district20.
What are the steps to build a home in Hunt County?
First, confirm whether your parcel is inside the Lake Tawakoni zoning area, within 5,000 feet of the Sabine River Authority property, since that changes what you can build and where19. Second, check whether any part of your property contains floodplain; if it does, get a Development Permit from the Hunt County Health Department before you can receive a 911 address or a septic permit15. Third, order a site evaluation for your septic system early, since only 0.5% of the county's soils are free of severe limitations for a conventional drain field10. Fourth, apply for your OSSF permit through the Hunt County Health Department and use a Texas-licensed septic installer, unless your tract qualifies for the state's 10-acre exemption1725. Fifth, if you're installing a new driveway, stake the proposed culvert location and notify Hunt County Development; a representative inspects it within 14 working days, and the finished culvert needs 30 to 60 feet of pipe with at least 6 inches of cover material9. Sixth, if your driveway connects to a state highway instead of a county road, apply to the local TxDOT district office using Form 1058 and give TxDOT 24-hour notice before construction26. Seventh, build: outside the Lake Tawakoni zone there's no countywide building-permit review or inspection to schedule for an ordinary single-family home2.
What should you check before buying land in Hunt County?
Water and soils go together here: Hunt County averages 43.6 inches of rain a year, but 17% of years bring severe drought, and with only 0.5% of soils free of septic limitations, both a reliable well and a well-planned septic design deserve real budget272810. Land is flat and largely open: all of the county, 100%, sits at 15% slope or less, and 25.3% is wooded, which keeps site work simple but means little natural tree cover on most tracts2930. Check whether your parcel falls within 5,000 feet of Lake Tawakoni before you buy, since that's the one part of the county with real zoning, lot-size minimums, and building restrictions19. Check FEMA floodplain maps too, since any floodplain on the property triggers a Development Permit before you can get a 911 address or septic permit15. Typical property tax runs about 1.3% effectively, with a median bill near $2,736 a year, and the typical home value in the county is around $277,139313233.
Watch-outs
- Outside the Lake Tawakoni zoning area, we could not confirm a formal owner-builder exemption or county building-code adoption; ask Hunt County Development about the exact parcel and project816.
- Private-well permitting and registration requirements remain unconfirmed; ask Hunt County Environmental Services which groundwater district or state office covers the parcel before drilling17.
