Unincorporated Maverick County

No public Maverick County source reviewed documented a general county building permit requirement for ordinary vertical construction in unincorporated areas. Verified narrower controls are: floodplain administration in unincorporated Maverick County; and OSSF permits where state and local septic rules apply. TCEQ states OSSF permits are required to construct, install, alter, extend, or repair an OSSF, subject to limited exceptions such as certain 10-acre-rule situations and emergency repairs.

Note: No public Maverick County exempt-work list was found for a general building-permit program. For OSSF only, TCEQ states a permit is not required for qualifying 10-acre-rule systems and is also not required for listed emergency repairs, provided those repairs are reported to the permitting authority within 72 hours after work begins.

Building code

No public Maverick County webpage or ordinance source reviewed documented a countywide adopted building code or countywide general building-code enforcement program for unincorporated Maverick County.

Owner-builder

For OSSF only, TCEQ states an owner may install a system for a single-family dwelling the owner owns, on property the owner owns, if no part of the property will be developed for sale or lease and all permitting and construction requirements are met.

Contractor requirements

No public Maverick County general-contractor registration or county contractor-license program was found for unincorporated building work. TCEQ licensing rules still apply to OSSF installers and certain septic-related participants.

1. 01
   Confirm the parcel is outside Eagle Pass city limits and in unincorporated Maverick County.
2. 02
   Contact Maverick County Planning to verify whether the project triggers any county-administered review, especially floodplain review in mapped special flood hazard areas.
3. 03
   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. 04
   If the site is in a mapped floodplain, coordinate with the county floodplain administrator before development.
5. 05
   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.

Typical sequence: No public county building inspection process was found for general construction. For OSSF, inspections and reporting are handled through the applicable OSSF permitting authority under TCEQ rules.
