Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
No fixed development, floodplain, OSSF inspection, or driveway-review time is published. The April 13, 2026 subdivision rules require Commissioners Court to approve, conditionally approve, or disapprove a complete plat application within 30 days after receipt and Development Officer sign-off; a qualifying written extension may add no more than 30 days. Under state OSSF rules, a complete septic application must be approved or denied within 30 days. OSSF Authorization to Construct and floodplain permit work are each subject to a one-year completion period unless the applicable extension or new application is obtained.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.

Submit the complete paper packet with the recorded deed, legal plat, scaled site drawing, verified 911 address, and required design documents to the Permitting and Development Office; incomplete applications are not accepted. Call 830-393-8357 to coordinate development, septic, and driveway inspections. Do not begin OSSF work before Authorization to Construct, and do not occupy or operate the system until it passes final inspection and the county issues a License to Operate. Authorization is valid for 12 months; if final inspection is not completed within one year, a new application and fee are required. A concrete county-road driveway requires a pre-pour inspection. Projects in a special-flood-hazard area require the applicable elevation certificate, and development with a footprint of three acres or more requires a drainage study.
Wilson County requires permits for development, driveways, and septic work. Floodplain development is administered under the Wilson County Flood Damage Prevention Order using the November 26, 2010 FIS/FIRM and later revisions. The current Wilson County Subdivision and Development Rules and Regulations were adopted April 13, 2026 and incorporate the 2021 International Fire Code for subdivision water supply, fire flow, and emergency access. OSSFs are governed by the Wilson County local order, Texas Health and Safety Code Chapter 366, and 30 TAC Chapter 285; professional OSSF design is required. The county does not publish a conventional residential structural-building permit or countywide IRC/IBC trade-code program; its published packet covers floodplain/development, OSSF, and driveway approvals. The county publishes no cosmetic- or minor-work exemption list and states that permits are required for any development, driveway, or septic work. A property outside the special-flood-hazard area may receive a floodplain exemption certificate only after the county reviews the development application and makes that determination; the application and $100 determination fee still apply. Subdivision plat exemptions exist for certain divisions qualifying under Texas Local Government Code Section 232.0015, including specified agricultural and qualifying family divisions, but those exemptions do not waive separate floodplain, driveway, or OSSF requirements.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
