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 Gillespie County.

Gillespie County’s current program requires OSSF planning materials, application, permit, and inspection for construction, alteration, extension, or repair of any OSSF, including systems on tracts of 10 acres or more. OSSF work follows Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285, plus the Gillespie County OSSF Order effective October 14, 2025. Floodplain work follows the county Flood Damage Prevention Ordinance effective July 28, 2025; no general countywide ICC building-code edition was verified.

Inspection lane

Obtain and complete the OSSF application, including property/legal description, site information, installer details, and planning materials. Since August 1, 2025, obtain a Development Permit Determination and Site Plan with Narrative from the County Engineer before submitting the septic application; the OSSF application is incomplete without the signed determination. For floodplain development, email the completed development permit and supporting documents to floodplain@gillespiecounty.org or submit hard copy to the courthouse. The OSSF permit is valid for one year from purchase; after construction, the county issues Authorization to Construct/Notice of Approval through its inspection process and requires applicable aerobic affidavits and maintenance contracts.

Minor-work playbook

Understand what may be exempt—and what is not.

The county’s 2025 OSSF order requires permitting and inspection for all OSSF construction, alterations, extensions, and repairs regardless of tract size, so the ordinary 10-acre state exemption is not a county exemption. Aerobic systems and other systems identified by the county require maintenance by a TCEQ-registered technician or licensed maintenance provider rather than the homeowner. The reviewed materials do not publish a broad cosmetic building-work exemption list.

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.

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.

Which codes and exemptions should I review?

Gillespie County’s current program requires OSSF planning materials, application, permit, and inspection for construction, alteration, extension, or repair of any OSSF, including systems on tracts of 10 acres or more. OSSF work follows Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285, plus the Gillespie County OSSF Order effective October 14, 2025. Floodplain work follows the county Flood Damage Prevention Ordinance effective July 28, 2025; no general countywide ICC building-code edition was verified.

The reviewed materials do not publish a broad cosmetic building-work exemption list.

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.
