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.
Fee desk contact
Permits main: 713-274-3900; Residential: 713-274-3920; Development Inspections: 713-274-3924; septic inspection questions: 713-274-3800
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
Harris County Office of the County Engineer, Development Services & Permits Division is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact Permits main: 713-274-3900; Residential: 713-274-3920; Development Inspections: 713-274-3924; septic inspection questions: 713-274-3800.
Residential construction and OSSF plan review: 30 business days. Published processing times vary by permit type; for example, sign permits list 3-5 business days. Harris County states that it does not offer expedited review, except possible case-by-case coordination for emergencies.
Request development inspections through the Harris County ePermits Inspection Request portal by entering the permit number, or contact Development Inspections at 713-274-3924. Residential builders or qualified third-party inspectors must record foundation, framing/mechanical, and final inspection results in the county Residential Building Code Inspection System. For septic inspections, the licensed installer must give at least 24 hours' notice through the online form or by phone at 713-274-3800; a valid septic permit and county-stamped approved plans are required.
In unincorporated Harris County, single-family and duplex construction permitted on or after September 1, 2009 is subject to Harris County Residential Building Code Standards and the residential inspection-notification system; county materials identify the 2006 International Residential Code or the code applicable in the county seat under Texas Local Government Code Chapter 233. Commercial/public buildings and multifamily dwellings of four or more units are governed by the Harris County Fire Code Regulations effective October 1, 2025. Floodplain development, civil/site work, stormwater, driveway, OSSF, and other county regulations also apply according to project scope. No county demolition permit is required for demolition work in unincorporated Harris County, although later construction or development requires a permit. A residential fence outside a Special Flood Hazard Area does not require a county permit. These are narrow exemptions: the county's residential application otherwise covers new homes, additions/remodels, garages, carports, pools, accessory structures, driveways, fill, and on-site sewage systems; municipal rules apply inside incorporated cities.
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.
