When a permit is required
Permit triggers and exempt work for Aransas County
No verified countywide general building-permit requirement was found for ordinary unincorporated construction. Verified county permits are narrower: floodplain development permits in regulated floodplain contexts; septic permits through Environmental Health where public wastewater is unavailable; development review and additional permits for manufactured-home and other rental communities, including tree permits and county right-of-way driveway permits in those covered situations.
- Exempt Ordinary maintenance and repair of structures (where determined by the Floodplain Administrator not to increase flood risk or create a code issue)
Note: No public exempt-work list was found for a countywide general building-permit program because no countywide general building-permit program was verified. Outside the narrower county-regulated categories (floodplain, OSSF, rental-community, tree, driveway), the reviewed county materials do not support assuming a city-style county building permit is required.
- Varies by permit type. Rental-community applications must include a site development plan for County Engineer and Environmental Health review. Floodplain permits require floodplain compliance materials. OSSF permits require septic design and related health-department materials.
- Building code
- No countywide general building code adoption was verified for ordinary unincorporated construction. County Commissioners Court minutes from February 12, 2024 state the county does not have building codes. The county's verified regulations instead focus on floodplain management, OSSF, rental-community infrastructure, trees, stormwater, and county right-of-way controls.
- Permit validity
- The county floodplain order states approved permits lapse if the proposed development does not begin within 180 calendar days from issuance, with possible 90-day extensions for cause.
- Owner-builder
- No public owner-builder rule was identified in the reviewed county materials.
- Contractor requirements
- For septic systems, the county order requires systems to be designed and installed by licensed professionals. No countywide general contractor-licensing program was verified for ordinary unincorporated building work.
Application process
Typical processing: No countywide processing-time estimate was identified in the reviewed materials.
- 01 First confirm the property is in unincorporated Aransas County and not inside Rockport, Fulton, or Aransas Pass city limits.
- 02 Determine which county-controlled permit category actually applies. The main county-controlled categories are floodplain development, OSSF or septic permitting, rental-community infrastructure permits, tree permits in covered situations, and county right-of-way driveway or culvert permits.
- 03 If the property lacks public wastewater, obtain OSSF approval from Aransas County Environmental Health. The county floodplain order states no building permit will be issued until an Environmental Health septic permit has been obtained in covered situations.
- 04 If the site is in the regulated floodplain, submit for the county floodplain development permit and provide whatever floodplain documents the Floodplain Administrator requires.
- 05 If the project is a new or expanded rental community in unincorporated Aransas County, submit the site development plan to the County Engineer and Director of Environmental Health for review and approval, along with utility, floodplain, tree, and driveway compliance items required by Order O-03-2020.
- 06 If the work includes a driveway over county right-of-way in a covered rental-community context, obtain the driveway and culvert permit through Aransas County Road and Bridge.
- 07 Complete required inspections for septic and any other county-regulated permit category before occupancy or utility connection in those covered contexts.
Typical processing time: No countywide processing-time estimate was identified in the reviewed materials.
Required inspections
Scheduling and sequence
- Inspection hours
- Not publicly stated in the reviewed materials.
Typical sequence: No countywide building-inspection scheduling program was found. Inspections appear to be permit-type-specific, especially for OSSF or septic and floodplain compliance. OSSF permits include future maintenance inspections as required. Floodplain oversight is handled through the Floodplain Administrator. Rental-community materials also tie issuance to OSSF approval and compliance with floodplain, tree, and driveway rules.
