Project questions
Frequently asked questions for Wharton County
Who handles permitting for this jurisdiction?
Wharton County Permit & Inspection Department is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
No verified online portal was located in the reviewed public materials. Contact Permits, inspections, floodplain, OSSF, and rural addressing: 979-532-8587; County Drainage Department: 979-532-9470 and request the current application route before preparing a final submittal.
How long might review take?
Wharton County publishes no fixed floodplain-development or OSSF counter turnaround. Under 30 TAC Chapter 285, a complete OSSF application and planning materials must be approved or denied within 30 days. Subdivision applicants submit the plat/design to the listed county reviewers at least 30 days before the requested action; after departmental approval, the matter goes to the next regular Commissioners Court meeting. Drainage approvals remain valid for 12 months; the authority may grant one good-cause extension of up to 12 months when requested before expiration.
How are inspections scheduled?
Call 979-532-8587 for an appointment and inspection coordination; the county advises calling because its permit official conducts daily inspections. Submit repair estimates before post-flood repair and do not begin work until the office determines whether a floodplain permit is required. The OSSF application authorizes county entry during daylight hours for sewage-facility inspection; at inspection, required backfill must be onsite and all tank compartments filled with water. For subdivision improvements, coordinate construction inspection intervals and testing with the County Engineer before work; after completion the project engineer requests inspection with compliance affidavits, test reports, and record drawings, and the County Engineer issues a deficiency punch list where needed.
Which codes and exemptions should I review?
Wharton County publishes no countywide IBC, IRC, electrical, plumbing, mechanical, or general structural building-permit program for ordinary construction in unincorporated territory. Its Permit & Inspection Department administers floodplain-development permits under the Wharton County Flood Damage Prevention Ordinance and FEMA/NFIP criteria, OSSFs under the county order, Texas Health and Safety Code Chapter 366, and 30 TAC Chapters 30 and 285, rural addressing, and subdivision/development review. The 2023 Wharton County Subdivision Platting Policy and county Drainage Criteria Manual regulate subdivision infrastructure, drainage, floodplain delineation, roads, and related construction. Incorporated cities administer their own building permits and adopted codes. Ordinary unincorporated construction outside a Special Flood Hazard Area has no published county general structural permit requirement, although septic, subdivision, drainage, driveway/right-of-way, and other applicable approvals remain required. The county's post-flood guidance says repairs outside the flood zone require no flood-repair permit after the Permit & Inspection office verifies and documents the address. No acreage exemption applies to septic systems: Wharton County expressly requires an OSSF permit for every installation regardless of tract size, and all OSSF construction must be performed or supervised by a licensed installer. Contact the office before cleanup or repair because the county does not publish a separate list of cosmetic-work exemptions.
