Codes, exemptions & field inspections

Build to the adopted code. Verify every exception.

This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.

Regulatory framework

The code baseline for McMullen County.

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.

Inspection lane

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.

Minor-work playbook

Understand what may be exempt—and what is not.

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.

Field rule

A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.

Inspection pipeline

Keep the work visible at every release point.

  1. 1

    Request with lead time

    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.

  2. 2

    Preserve access

    Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.

  3. 3

    Close the record

    Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.

Contractor verification

Verify the builder before the contract is signed.

Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.

Planning reference

Keep the parcel rules beside the building plans.

A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Project questions

Frequently asked questions for McMullen County

Who handles permitting for this jurisdiction?

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.

How should I begin an application?

No verified online portal was located in the reviewed public materials. Contact Courthouse/Floodplain Administrator: 361-274-3900; OSSF: 361-449-8043; Public Works: 361-274-3910 and request the current application route before preparing a final submittal.

How long might review take?

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.

How are inspections scheduled?

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.

Field sequencing matters

The inspector needs to see the work at the right moment.

Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.

When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.

Closeout file

Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
