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

An ordinary single-family home in unincorporated Kenedy County does not require prior county approval before construction^1,2. Texas counties that qualify may adopt residential standards for new single-family houses and duplexes, but the state framework itself does not require prior county approval or allow a county enforcement fee². We could not confirm that Kenedy County adopted the resolution needed to apply those standards, so ask the County Judge's Office whether inspections or a certificate of occupancy apply to the project^2,11. An owner-builder who intends to use the house as a primary residence can qualify for a narrow exemption from the penalty for failing to give inspection notice; that is not a general exemption from codes, inspections, septic rules or permits². State standards separately apply to industrialized housing, buildings, modules and modular components¹².

Kenedy County does not present a dedicated residential building-permit office, so the practical county contact is the Kenedy County Judge's Office at 151 N. Mallory in Sarita, phone 361-294-5224¹¹. Ask that office about any unpublished inspection, occupancy, floodplain or fee requirement tied to the parcel¹¹. Kenedy County itself is the local authorized agent for on-site sewage facilities, although the available county page does not identify a dedicated septic desk or application portal⁹. The Kenedy County Groundwater Conservation District is the separate authority to contact about drilling, operating or substantially altering a water well within its jurisdiction⁶. A new or changed driveway connecting to a state highway goes through TxDOT's permit process, not an assumed county driveway approval⁸.

Unincorporated Kenedy County has no county zoning ordinance, and Texas does not grant Kenedy County general zoning authority^3,4. The county therefore sets no zoning-based minimum dwelling size, minimum lot size, setback, lot-coverage limit, height limit or use district in unincorporated Kenedy County⁴. The same answer covers county zoning of accessory dwellings, manufactured-home occupancy, RV occupancy, tiny-home occupancy and temporary camping⁴. No county zoning does not erase separate septic, well, subdivision or state-highway access requirements^5,6,7,8. If a purchase involves splitting land outside municipal limits, confirm platting before closing: divisions for subdivisions, lots or public-use features can require a plat approved by the commissioners court and recorded with the county clerk⁷.

Kenedy County is TCEQ's authorized local agent for on-site sewage facilities in the county⁹. A permit and approved plan are generally required before constructing, installing, altering, extending or repairing an OSSF, and the local program may be stricter than the state minimum⁵. A qualifying single-family tract of at least 10 acres may use the state exception only after a licensed site evaluation and only when every condition is met, including keeping every system component at least 100 feet from the property line, retaining effluent on the property and serving the tract's only dwelling⁵. The installer generally must notify the permitting authority at least 5 working days before the system is ready for construction inspection¹³. Only about 16% of county soils are rated without severe limits for a conventional drain field, making an early site evaluation especially useful¹⁴.

Kenedy County does not impose a zoning-based restriction on RV occupancy, tiny-home occupancy, manufactured-home occupancy or temporary camping in its unincorporated area⁴. That answer concerns county zoning; it does not waive sanitation rules for wastewater generated on the property⁵. An OSSF generally needs a permit and approved plan unless every condition of an applicable exception is satisfied⁵. A modular or industrialized tiny home can also fall under the state's industrialized-housing code program even though Kenedy County does not require an ordinary residential building permit^1,12. The county has not confirmed local rules for composting toilets, graywater or utility connections, so ask Kenedy County's OSSF authority how the proposed setup must handle wastewater before placing or occupying the unit⁹.

1. Confirm that the parcel is in unincorporated Kenedy County and ask the County Judge's Office whether residential inspections, occupancy requirements or floodplain review apply^2,11.

1. Ask the Kenedy County Groundwater Conservation District whether the proposed well needs a district permit or qualifies for an exemption before drilling or altering it^6,15.

1. Submit the septic plan and permit materials to Kenedy County unless the OSSF authority confirms that every condition of an exception is met^5,9.

1. Arrange the required OSSF construction inspection and have the installer provide at least 5 working days' notice¹³.

1. For access onto a state highway, submit TxDOT Form 1058, receive the executed permit, and provide 24-hour notice before right-of-way construction⁸.

1. If the land is being divided outside municipal limits, resolve plat approval with the commissioners court before relying on the new tract layout; ask the county whether an agricultural exception applies to the proposed division^7,10.

Start with wastewater suitability because only about 16% of Kenedy County soils are rated without severe limitations for a conventional septic drain field¹⁴. Confirm the groundwater district's permit or exemption decision before assuming a well can be drilled as planned⁶. For a driveway onto a state highway, budget time for TxDOT Form 1058, an executed permit and the required 24-hour preconstruction notice⁸. If the seller is dividing a larger tract outside municipal limits, confirm county plat approval and recording requirements; an agricultural exception is conditional on qualifying use and no public-use layout^7,10. Kenedy County requires a telecommunications-tower applicant to obtain county approval and verify that the site is outside a flood zone, but we could not confirm the general floodplain process for a home; ask the County Judge's Office before building^11,16.
