Permit Fees in Houston, TX

Houston doesn't roll everything into one fee. You need separate permits for building, plumbing, electrical and HVAC. The 2026 Building Code Enforcement Permit Fee Schedule lays this out across several pages. Most small home projects hit the $91 minimum for the building permit. Then you pay 25 percent of that for plan review. And the $34 admin fee is non-refundable. I had to cross reference three different pages to confirm how the trades stack up. Plumbing runs $34 for the first three fixtures then $11 for each additional one. The minimum there's $98. Electrical often lands at its own $91 minimum. HVAC uses 2 percent of valuation plus $47. A kitchen remodel with $25,000 valuation ends up at $384 total. That isn't cheap. But it's predictable once you know the formula. Residential alterations use the commercial valuation table or just the minimum. New homes follow sqft tiers under HB 852 and Ord. No. 2023-907. The calculator on this page uses those exact rules. Plug in your project. It beats guessing. (The PDF buries some of these details on page 2 and 3.) If your project stays under the thresholds you'll pay the minimums every time.

You need a permit for most work that changes the house. A roof replacement requires one. So does a bathroom remodel or deck construction. Fences trigger fees at $74 for the first 100 linear feet. Window replacements and water heater swaps also need approval. The rules don't list every exemption clearly in Chapter 10. Don't assume your shed or carport is exempt. Same for finishing a basement. Houston Public Works uses the 2026 fee schedule to enforce this. Skip the permit and you can't get final inspections. That creates problems later. The city doesn't make the full exemption list easy to find. Check before you start work. Better to know than to pay double later.

Unpermitted work gets expensive fast in Houston. Application fees are doubled under Bldg. Code Sec. 118.1.15. The investigation fee hits $333.42 minimum or double the normal fee whichever is greater. Sec. 10-99(b) and Sec. 1-6 back this up. You can't just pay the regular rate after the fact. The city doesn't forgive skipped permits easily. That $91 minimum building fee becomes much more. Add the doubled plumbing and electrical charges on top. Nobody wants that surprise. (I found these penalty rules outside the main fee table.) If you get caught through a neighbor complaint or sale the costs add up. Pay the fee up front instead.

The 2026 fee schedule doesn't list permit duration details. Those rules live in the separate Houston Construction Code. We couldn't find the exact time to commence or abandonment period in Chapter 10. Check directly with Houston Public Works. Most cities require you to start work within a set number of days. Houston follows similar logic. Extensions exist but the fee schedule doesn't spell them out. Don't let your permit sit too long. The city won't renew indefinitely without action.

Chapter 10 doesn't clearly state who must pull the permit. Contractors normally handle this in their name. Homeowners can sometimes pull permits for their own home. The data stays thin on exact rules here. Let your contractor pull it. They carry the insurance and understand the inspection process. You don't want to be responsible if something fails. Many contractors won't work without the permit in their name. Ask up front, and the wrong choice creates headaches later.

Houston stands apart because of its separate trade permits. One building permit doesn't cover plumbing or electrical here. You pay for each. The city adopted HB 852 through Ord. No. 2023-907 for residential dwellings. That shifts new construction to sqft based tiers. Remodels still fall back to the valuation table or minimum fees. The $34 admin fee hits every permit. Plan review adds 25 percent on the building side and it's non refundable. I cross referenced the valuation table on page 1 with the trade fees on pages 2 and 3. The system creates consistent but higher costs than flat fee cities. You can't bundle everything into one payment. The calculator accounts for all these layers. Know this before you start. If the bid doesn't break out each trade permit then the numbers are wrong.
