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.

Gonzales County publishes a 5-7 working-day processing estimate for septic applications and floodplain permits. Septic fees are $310 for conventional systems, $410 for aerobic/engineered systems, and $510 for commercial/industrial systems; floodplain fees are $100 residential and $350 commercial.
For a septic permit, obtain a site evaluation, then submit the completed application, site-evaluation report, approved 911 address, abstract card, proof of ownership, aerobic affidavit and maintenance contract when applicable, and driveway permit. Gonzales County states that applications are reviewed in about five working days and should be allowed 5-7 working days to process. The county issues a License to Construct valid for one year; contact the permit office for inspection and approval procedures. Floodplain permits are also generally approved in 5-7 business days and are valid for one year.
Gonzales County’s permit office administers unincorporated-area floodplain, septic/OSSF, subdivision, driveway, road-bore, seismic, utility/pipeline, and water-line permits. OSSF permitting follows Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285; floodplain development follows the county Flood Damage Prevention Order. No general countywide ICC building-code edition was verified. The reviewed county materials do not publish a broad cosmetic building-work exemption list. State OSSF exemptions may include a qualifying single-family system under the 10-acre rule and specified emergency repairs reported within 72 hours, but the applicant must satisfy all TCEQ conditions and confirm applicability with the county. County floodplain and subdivision requirements may still apply to otherwise exempt work.
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.
