About each permit

Non-Residential On-Site Sewage Facility (Septic) Permit

Engineering Services' fee page states the Commissioners Court approved its current fees on 14 July 2026 by Court Order 147297, effective 1 October 2026. That Engineering Services Fee Schedule 2026, and the county's OSSF permit page, price a non-residential system at $277 for a conventional system and $285 for an aerobic system; repair or remodel is $117 and a re-inspection $92. The February 2026 application says it is valid for one year from the date the fees are received, and an older undated information sheet still linked from the page shows lower figures that the 2026 schedule replaces. The county's OSSF page says it regulates septic permits for 23 cities and the unincorporated county.

Floodplain Permit (unincorporated county)

The county's Guidelines for Development in the Unincorporated Areas (April 2025) state that all development and new construction within a FEMA-designated floodplain requires a floodplain permit before any work begins, and that a flood study may be required depending on the site. The Engineering Services Fee Schedule 2026, approved by Court Order 147297 and effective 1 October 2026, prices the floodplain permit application at $34, adding that if a floodplain study is required a flood study review fee may also apply. A site outside the floodplain has no floodplain permit. Inside a city, the city administers its own floodplain rules.
