No verified online portal was located in the reviewed public materials. Contact Walker County Planning and Development: 936-436-4939; County Clerk deed-record room: 936-436-4924 and request the current application route before preparing a final submittal.

A new 911 address takes approximately 7-10 business days. The county instructs applicants to allow 30-45 minutes for the in-office permit process once all prerequisites and documents are ready, but publishes no guaranteed development-permit review target. Complete OSSF planning materials must be approved or denied within 30 days under 30 TAC Chapter 285. An application, related variance/review, and any issued permit expire after 180 days unless extended in writing.

Obtain a valid county 911 address, then apply in person with the recorded deed, owner photo ID or notarized authorization, scaled site drawing, floor plan, and fee. A City of Huntsville Certificate of Compliance is required first for development within its ETJ. Allow 30-45 minutes for the office permit transaction. The application authorizes county representatives to inspect development and OSSFs; contact Planning and Development at 936-436-4939 to arrange required site, floodplain, and OSSF inspections. Do not begin development before the Development Permit or OSSF Authorization to Construct is issued. Keep the OSSF uncovered until the county completes its pre-cover/final inspection and issues approval to operate.

Walker County requires a development permit before construction or development on improved or unimproved property in its extra-municipal area. The permit administers Walker County Flood Plain Management Regulations and FEMA FIRM/FIS requirements; development in an identified flood hazard area must meet county elevation, floodproofing, drainage, anchoring, and documentation standards, including a minimum finished-floor elevation 12 inches above base flood elevation unless a variance is granted. Planning and Development also enforces county OSSF regulations under Texas Health and Safety Code Chapter 366 and 30 TAC Chapters 30 and 285, subdivision regulations, driveway/culvert rules, nuisance rules, and 911 addressing. The county publishes no adopted general IRC, IBC, electrical, plumbing, mechanical, or fire-code edition and does not represent the development permit as a structural code inspection. Huntsville, New Waverly, Riverside, and applicable municipal ETJs impose separate requirements. All county extra-municipal development described in the application—including site-built and manufactured homes, recreational vehicles, commercial work, accessory structures, substantial improvements, watercourse alteration, and fill—requires a development permit; no blanket cosmetic or small-accessory-structure exemption is published in the permit packet. A replacement, reconstruction, or addition within an existing structure's original footprint that will use an unchanged, adequately sized OSSF may use the county OSSF Change of Structure review instead of a new-system application. State OSSF exemptions may apply to an otherwise compliant system serving the only single-family dwelling on at least 10 acres after licensed evaluation when every component is at least 100 feet from property lines, effluent stays on the tract, and no nuisance or groundwater pollution occurs; confirm eligibility with the county.
