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.

N/A for ordinary development and septic plan review. Fire Marshal expedited handling in fewer than five working days or after hours is offered for a $500 fee. Development permits expire 180 days after entry into the permitting system regardless of review status; after release, construction must begin within 180 days and proceed without interruption.
For OSSF inspection, submit a request to Environmental Health by 3:00 PM at least two business days before the needed inspection; obtain approval before backfilling or use. Floodplain and development inspections are coordinated through the Permit Department, and required elevation or engineer certifications must be supplied for floodplain work. Commercial/public and qualifying multifamily projects submit fire plans to the Fire Marshal and use the county Request for Fire Code Final Inspection form; call 936-538-8288 for scheduling.
Montgomery County Floodplain Management Regulations effective October 1, 2025; 2024 International Fire Code with county amendments, appendices B, C, D, H, I, J, L and P, and only the specified 2024 International Building Code chapters incorporated by the county fire code, effective May 14, 2025; current NFPA 101 provisions cited by the Fire Marshal; county OSSF rules and 30 TAC Chapter 285; Development Regulations adopted March 4, 2025 and amended through April 9, 2026. Fire/building-code scope is commercial and public buildings and multifamily complexes of four or more units. The October 2025 rules exempt listed work subject to drainage safeguards: three-strand barbed-wire fences; limited residential or commercial clearing outside special flood hazard areas with no drainage alteration; basic upkeep/remodeling that is not a substantial improvement in a flood area; weather-event debris cleanup; limited residential excavation/fill outside flood areas under 15,000 square feet and 500 cubic yards; qualifying stored recreational vehicles; qualifying old nonpermitted development outside the floodway; agricultural maintenance outside flood areas; demolition outside flood areas under 500 square feet; same-material fence repair in flood areas; and fences and pools outside flood areas. All other property development requires a permit, and each structure or addition requires a separate permit.
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.
