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
A complete OSSF permit application and planning materials are subject to the 30-day approval-or-denial period in 30 TAC Chapter 285. The county publishes no standard floodplain review time. A pipeline/road-crossing permit expires 90 days after Commissioners Court approval if installation has not occurred, and the applicant must give 24 hours' notice before road work. A separate 911 address request normally takes 3-5 days.
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.
Application documents
Before submission, call Courthouse/Floodplain Administrator: 361-274-3900; OSSF: 361-449-8043; Public Works: 361-274-3910 if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.

Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.

McMullen County Floodplain Management and OSSF Program is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.

Submit the county OSSF packet with recorded deed, site/soil evaluation by a licensed evaluator or engineer, scaled planning materials and design, fee, and any required aerobic affidavit and maintenance contract. Do not begin before application approval; keep the approved application at the job site, leave the system uncovered, and call 361-449-8043 for final construction inspection. A permit to operate follows successful inspection. For floodplain work, submit the county's 2026 application with scaled site/elevation plans and required engineer, architect, or surveyor certifications to the courthouse; watercourse or drainage changes require a certified hydrologic and hydraulic study.
McMullen County administers its Flood Damage Prevention Ordinance/NFIP requirements through County Judge and Floodplain Administrator James E. Teal, enforces OSSF planning and construction under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285, applies subdivision regulations, and requires pipeline/road-crossing permits. The current flood application covers new structures, additions, relocation, demolition, replacement, manufactured homes, clearing, filling, grading, mining, drilling, excavation, subdivision, drainage/waterway alteration, roads, bridges, and utility work. No countywide ICC structural building-code edition or general building-permit program was found. No county cosmetic-work exemption list is published. A floodplain exemption certificate may be issued when development is outside the regulated special flood hazard area, but that determination does not exempt OSSF, subdivision, access, pipeline, or other agency approvals. The county-hosted OSSF guidance recognizes the state 10-acre single-residence exception only when the tract is at least 10 acres, every field/sewage disposal line is at least 100 feet from a property line, effluent remains on the tract, and the system creates no nuisance or groundwater pollution; confirm eligibility before construction.
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.
