Application Process

1. Confirm the parcel is outside Eagle Pass city limits and in unincorporated Maverick County.
2. Contact Maverick County Planning to verify whether the project triggers any county-administered review, especially floodplain review in mapped special flood hazard areas.
3. If the property involves an on-site sewage facility, use TCEQ's county lookup and submit to the local OSSF permitting authority identified there, or to TCEQ if no authorized local program applies.
4. If the site is in a mapped floodplain, coordinate with the county floodplain administrator before development.
5. Because no public countywide general building-permit program was found, confirm parcel-specific requirements directly with the county before relying on an assumption that no permit is needed.

Typical processing time: TCEQ states OSSF permit applications must be approved or denied within 30 days by the permitting authority.
