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

Outside the Lake Tawakoni planning area, Hunt County does not administer a general building-permit program¹. Hunt County’s general guidance says the county does not issue Certificates of Occupancy or require building inspections; the Lake Tawakoni commercial process has a separate final-approval requirement³. Within the Lake Tawakoni planning area, the ordinance adopts building, mechanical, plumbing, pool and electrical codes and requires a building permit before erection, alteration or conversion⁴. Permitted commercial construction there requires a final inspection and final approval before occupancy¹⁰. A floodplain Development Permit, county subdivision plat approval, a new-driveway culvert permit and a septic permit are separate approvals that may still apply even when no general county building permit does^3,5,11,12.

For unincorporated Hunt County, start with Hunt County Development about Lake Tawakoni zoning, floodplain Development Permits and subdivision plats; county culvert permits are available from the Commissioners’ Office^3,12,13. Hunt County Development is at 2507 Lee Street, First Floor - Room 107, Greenville, TX 75401, (903) 408-4204, development@huntcounty.net¹³. The Lake Tawakoni Planning Commission issues building permits in its planning area⁴. Royse City, which reaches into Hunt County but lies mainly in Rockwall County, issues its own building permits; its Building Inspection Department also receives septic applications^14,15. Elsewhere under the county septic order, contact the Hunt County Health Department’s Environmental Officers at 2701 Johnson St., Greenville, TX 75401, (903) 408-4140, health@huntcounty.net; cities with their own septic orders are excepted^5,6.

Unincorporated Hunt County has no county zoning more than 5,000 feet from Lake Tawakoni; the Lake Tawakoni Zoning Ordinance applies within 5,000 feet of Sabine River Authority property, administered through the Lake Tawakoni Planning Commission and Commissioners Court^3,4. County subdivision regulations and engineering standards still apply throughout unincorporated Hunt County³. Ask Hunt County Development to confirm the lake-area district for a parcel; we could not confirm a complete district map^3,13. In E-2, the minimum lot is 85,000 square feet, the minimum dwelling floor area is 1,000 square feet, and accessory dwellings are for family members only⁴. Outside the lake area, the county sets no zoning-based minimum dwelling size, lot size, setbacks, lot coverage or building-height limit³. Commerce sets its own city zoning, as does Royse City, a city that reaches into Hunt County^16,17. County septic authority remains separate, subject to city septic orders; Royse City receives its own septic applications^5,15.

Hunt County issues septic permits except where an incorporated city or township regulates systems under its own order; contracted cities and towns may remain under the county order⁵. 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 construct⁵. The published county fee sheet lists a residential septic permit at $335 and a commercial septic permit at $500¹⁸. A commercial installer must hold the proper current license, while an owner may install only with approval and a permit from the designated authority⁵. Within a city jurisdiction, the applicant needs a city letter stating that public or private sewer service cannot be provided⁵. Hunt County requires a septic permit regardless of lot size, and generally prohibits holding tanks unless allowed by permit⁵. The installer must give the county's designated representative at least 5 days' notice before a completed system is ready for inspection, and failed inspections bring a reinspection fee⁵. Only 0.5% of Hunt County soils lack severe limits for a conventional drain field, so arrange the site evaluation early⁹.

In unincorporated Hunt County more than 5,000 feet from Lake Tawakoni, the county has no zoning, so no county zoning district limits RV or manufactured-home occupancy there³. We could not confirm a county rule on living in a single RV or tiny home on an ordinary parcel, so ask Hunt County Development about your parcel¹³. That answer does not erase septic, floodplain, subdivision, or utility requirements^3,5,11. Hunt County separately regulates an unincorporated rental community or RV park designed for at least 3 recreational vehicles or temporary rental structures, with stays under 180 days without lease renewal⁷. Each developed parcel in a temporary rental community needs a development permit and scaled infrastructure plan, with Commissioners Court approval before construction; modifications require a new development permit, and remodeling or expansion ends the exemption from more stringent standards for existing parks⁷. In that setting, a tiny house or cottage must be under 400 square feet, occupy one RV space and use a mobile undercarriage⁷. In the Lake Tawakoni E-2 district, a temporary dwelling used during main-home construction must be removed within 6 months⁴.

1. Locate the parcel. Lake Tawakoni zoning approval and a building permit apply within 5,000 feet of Sabine River Authority property; inside a city, ask the city about its own building permit and zoning rules^2,3.

1. Check floodplain status; covered development requires a county Development Permit¹¹.

1. Order the septic site evaluation early because only 0.5% of county soils lack severe conventional-drain-field limits, then apply to the Hunt County Health Department unless another jurisdiction governs septic^5,6,9.

1. Obtain a county culvert permit for a new driveway under county jurisdiction, stake the culvert location (the county inspects the marked spot within 14 working days and sets the size, with a length of 30 to 60 feet); a state-highway connection instead follows the TxDOT driveway-permit process^3,19,20.

1. Submit a rural subdivision plat or temporary-rental-community infrastructure plan before construction when applicable; Commissioners Court reviews rural platting and must approve a new temporary rental community^7,12.

1. Outside the lake planning area, an ordinary home has no general county building permit, Certificate of Occupancy or county building inspection^1,3.

Before buying unincorporated Hunt County land, check the Lake Tawakoni zoning boundary, floodplain and road frontage: property containing floodplain needs a Development Permit before a 911 address or septic permit, and every new driveway under county jurisdiction needs a culvert permit³. Hunt County’s published preliminary plat fee is $600 plus $30 per lot, and the final plat fee is $600 plus $60 per lot; engineering review costs extra²¹. A short-term rental community’s development submittal is $600 plus $60 per unit, with construction/civil plan review listed at $1,500 for developments up to 100 lots; larger developments must call for the fee, and rental-community fees may change without notice²¹. A Lake Tawakoni agricultural subdivision exception requires a written request, no new access roads, no building improvements or land-use changes, and no circumvention of subdivision regulations⁴. Private-well permitting and registration remain unconfirmed; ask the Health Department which authority covers the parcel⁶. Typical effective property tax is about 1.3%, with a median annual bill near $2,736⁹.
