Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

Project questions
Gillespie County Sanitation (OSSF) Department / Engineering Department is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
No verified online portal was located in the reviewed public materials. Contact Gillespie County OSSF/Sanitation: 830-997-8191; Engineering/Floodplain/ROW: 830-307-6196 or 830-307-6048 and request the current application route before preparing a final submittal.
N/A; Gillespie County’s reviewed OSSF and floodplain materials do not publish a standard review timeline.
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.
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 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.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
