Kenedy County, TX Building Permits, Zoning & Septic

An ordinary single-family home in unincorporated Kenedy County, Texas does not require a county building permit¹. Kenedy County also has no county zoning, so it sets no zoning-based minimum home size, minimum lot size or setback there²³.

Do you need a building permit in Kenedy County, Texas?

An ordinary single-family home in unincorporated Kenedy County does not require a county building permit¹. Texas law gives counties only limited building authority, including conditional residential standards and fire-code authority for particular buildings and qualifying counties; it does not create a general county preconstruction approval system for every rural house¹². No Kenedy County owner-builder exemption was confirmed, so do not describe the project as exempt; the practical point is that the county residential building-permit program itself was not established¹⁰. Kenedy County has not published a confirmed rule for inspections or certificates of occupancy, so ask the County Judge's Office about the specific parcel and project before construction¹³. State standards separately apply to industrialized housing, buildings, modules and modular components¹⁴.

Who handles building and land permits in Kenedy County?

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 361-294-5224¹³. Ask that office about any unpublished inspection, occupancy, floodplain or fee requirement tied to the parcel¹³. 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 portal⁸. The Kenedy County Groundwater Conservation District is the separate authority to contact about drilling, operating or substantially altering a water well within its jurisdiction⁵. A new or changed driveway connecting to a state highway goes through TxDOT's permit process, not an assumed county driveway approval⁷.

Does Kenedy County have zoning?

Unincorporated Kenedy County has no county zoning ordinance, and Texas does not grant Kenedy County general zoning authority²¹⁵. 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 County³. The same answer covers county zoning of accessory dwellings, manufactured-home occupancy, RV occupancy, tiny-home occupancy and temporary camping³. No county zoning does not erase separate septic, well, subdivision or state-highway access requirements⁴⁵⁶⁷. If a purchase involves splitting ranch or agricultural land, confirm platting before closing: divisions for subdivisions, lots or public-use features can require a plat approved by the commissioners court⁶.

How do septic permits work in Kenedy County?

Kenedy County is TCEQ's authorized local agent for on-site sewage facilities in the county⁸. 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 minimum⁴. 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 dwelling⁴. The installer generally must notify the permitting authority at least 5 working days before the system is ready for construction inspection¹⁶. Only about 16% of county soils are rated without severe limits for a conventional drain field, making an early site evaluation especially useful¹⁷.

Can you live in an RV or tiny home in Kenedy County?

Kenedy County does not impose a zoning-based restriction on RV occupancy, tiny-home occupancy, manufactured-home occupancy or temporary camping in its unincorporated area³. That answer concerns county zoning; it does not waive sanitation rules for wastewater generated on the property⁹. An OSSF generally needs a permit and approved plan unless every condition of an applicable exception is satisfied⁹. 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 permit¹⁴¹. 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 unit⁸.

Building a home in Kenedy County: the steps, in order

Confirm that the parcel is in unincorporated Kenedy County and ask the County Judge's Office about any project-specific inspection, occupancy, floodplain or fee requirement not published online¹³.

Ask the Kenedy County Groundwater Conservation District whether the proposed well needs a district permit or qualifies for an exemption before drilling or altering it⁵¹⁸.

Submit the septic plan and permit materials to Kenedy County unless the OSSF authority confirms that every condition of an exception is met⁸⁴.

Arrange the required OSSF construction inspection and have the installer provide at least 5 working days' notice¹⁶.

For access onto a state highway, submit TxDOT Form 1058, receive the executed permit, and provide 24-hour notice before right-of-way construction⁷.

If the land is being divided, resolve plat approval or a qualifying agricultural exception before relying on the new tract layout⁶¹¹.

What should you check before buying land in Kenedy County?

Start with wastewater suitability because only about 16% of Kenedy County soils are rated without severe limitations for a conventional septic drain field¹⁷. Confirm the groundwater district's permit or exemption decision before assuming a well can be drilled as planned⁵. For a driveway onto a state highway, budget time for TxDOT Form 1058, an executed permit and the required 24-hour preconstruction notice⁷. If the seller is dividing a larger tract, county plat approval can apply; a conditional agricultural exception requires qualifying land use and no public-use layout, and ordinary platting returns if that qualifying use ends⁶¹¹. General county floodplain rules remain unconfirmed; the one verified county flood-zone condition applies only to telecommunications antennas or towers, so ask the County Judge's Office about ordinary development¹⁹¹³.

Watch-outs

No Kenedy County inspection or certificate-of-occupancy policy was confirmed; ask the County Judge's Office about the exact project before construction¹³.
The state septic acreage exception is conditional, not an automatic waiver for every large tract⁴.
Kenedy County's verified flood-zone restriction concerns telecommunications towers only; we could not confirm the general floodplain permit process for a home¹⁹.
Agricultural land divisions lose their conditional plat exception when qualifying use ends¹¹.
