Unincorporated Marion County

No countywide general building permit requirement found for ordinary building construction in unincorporated Marion County. A permit is required for onsite sewage facility (OSSF) work to construct, install, alter, extend, or repair a septic system, except for limited state-law exemptions such as qualifying 10-acre-rule systems and certain emergency repairs. County floodplain or environmental approvals may apply in specific circumstances.

• Exempt Qualifying 10-acre-rule systems under Texas state OSSF law

Note: No public exempt-work list found for a county general building permit program because no such documented countywide program exists. For OSSF work, TCEQ states certain emergency repairs are not required to obtain a permit but must be reported in writing within 72 hours after work begins.

Building code

No public countywide adopted building code for unincorporated Marion County found.

Permit validity

No public county building-permit validity terms found. OSSF expiration terms not confirmed from Marion-specific ordinance.

Owner-builder

For OSSF work, Texas state law allows owner installation for a single-family dwelling the owner owns, subject to local permitting-authority requirements and trade-license limits.

Contractor requirements

No county general contractor licensing program found. OSSF work is controlled by Texas state licensing rules administered through TCEQ for installers, site evaluators, designated representatives, and related roles.

1. 01
   Determine whether your project is in unincorporated Marion County and not within Jefferson city limits.
2. 02
   Confirm directly with Marion County whether any project-specific county control applies (general building permits are not countywide documented).
3. 03
   If the project requires an on-site sewage facility (OSSF), obtain a site evaluation and complete the NETMWD OSSF permit package.
4. 04
   Submit the OSSF application and planning materials to NETMWD, the Designated Representative serving Marion County for septic permitting.
5. 05
   NETMWD reviews the materials. TCEQ requires OSSF applications to be approved or denied within 30 days; subdivision or development planning materials within 45 days.
6. 06
   If the site is in a floodplain area or subject to federal grant-related floodplain review, coordinate with Marion County officials before disturbing the site.
7. 07
   After OSSF approval, install the septic system and obtain required inspections through the septic program before use.

Typical processing time: OSSF permits: 30 days for approval or denial; subdivision or development planning materials: 45 days.
