Do I need a permit for that? A Houston homeowner's guide

This guide covers the City of Houston. If you are in another city or in unincorporated Harris County, the section at the end explains how the rules change. Where a line says “depends” or “confirm,” call the Houston Permitting Center before you assume. Rules and fees change.

Common jobs and whether they need a permit

Job	Permit?	Who pulls it
Water heater replacement	Yes	Licensed plumber
Whole-house repipe	Yes	Licensed plumber
Sewer line repair or replacement	Yes, plus a right-of-way permit if it reaches the street	Licensed plumber
Electrical panel change or upgrade	Yes	Licensed electrical contractor
New circuit, subpanel or outlet run	Yes	Licensed electrical contractor
Standby generator	Yes, usually electrical and gas, sometimes building	Electrician and plumber, often under one contractor
EV charger	Yes	Licensed electrical contractor
AC or furnace replacement	Yes	Licensed HVAC contractor
Ductwork replacement	Usually yes, minor repair usually no	Licensed HVAC contractor
Re-roof	Yes	Roofer registered with the city
Foundation repair	Yes, usually with an engineer’s letter	Foundation company or engineer
Fence	Usually no under 8 feet, confirm for masonry and corner lots	Contractor or homeowner
Deck	Depends on height and whether it attaches to the house	Contractor or homeowner
Swimming pool	Yes, building, electrical, plumbing and barrier	Pool builder
Bathroom remodel	Yes if plumbing, wiring or walls move, no if cosmetic	Each licensed trade
Kitchen remodel	Same as bathroom	Each licensed trade
Window replacement	Depends, usually no for same-size replacement, yes if the opening changes	Contractor
Driveway	Yes where it meets the street, confirm for on-lot only	Contractor
Shed	Depends on size and whether it has power or water	Contractor or homeowner
Solar panels	Yes, electrical and building	Licensed electrical contractor

The pattern is simple. Gas, water, drains, wiring, roof, foundation and structure need a permit. Paint, flooring, cabinets, countertops and fixtures swapped in place do not.

How the Houston Permitting Center works

The Houston Permitting Center handles building, plumbing, electrical and mechanical permits for addresses inside the city limits. Most permits are applied for online.

The important part for you is who applies. For plumbing, electrical and HVAC work, the permit is pulled by the licensed contractor in their own name, under their state license and city registration. That is not a formality. It ties the work to a license that can be disciplined and it tells the city who to inspect.

After the work is done, the contractor schedules an inspection. A city inspector checks the work and passes it or writes a correction list. The permit is closed when the inspection passes. Ask for the permit number before work starts and ask for proof the inspection passed before you make the final payment.

You can search permit history for any Houston address through the city’s online permit records. Do this before you buy a house and after any contractor tells you a permit was pulled.

What happens without a permit

• Stop work order. If an inspector or a neighbor’s complaint brings the city out, work stops until a permit is issued. The crew leaves and your project sits open.
• Penalty fees. Permits applied for after work starts carry extra fees. Confirm the current penalty with the Houston Permitting Center, but expect to pay more than the normal fee, and expect to pay it yourself if the contractor is gone.
• Open walls. The inspector cannot approve what they cannot see. Finished drywall, tile or a slab may have to be opened.
• Trouble at sale. The Texas seller’s disclosure asks whether work was done without required permits. Buyers, inspectors and lenders check. Unpermitted work costs you negotiating room or kills the deal.
• Insurance. If unpermitted work causes a fire, a leak or a collapse, your insurer can question the claim. Whether they deny it depends on the policy, but you do not want to be the test case.

Why contractors skip permits

A permit costs money and time, and it brings an inspector who may fail the work. A contractor who offers to skip it is usually unlicensed, not registered with the city, or worried about the inspection. None of those are reasons that help you.

Outside the Houston city limits

Harris County has no city-style building department for unincorporated areas. The Harris County Engineering Department permit office handles permits there, and the list of what requires one is shorter. Your utility district, your HOA and your deed restrictions may add their own approvals.

Separate cities inside the metro run their own permit offices. Pasadena, Pearland, Bellaire, West University Place, Katy, Sugar Land, Missouri City and others each have their own rules and fees. Check your address, not your mailing city.

State licensing does not change with the permit office. A plumber needs a TSBPE license, an electrician and an HVAC contractor need TDLR licenses, and an irrigator needs a TCEQ license, whether or not the local office requires a permit for the job.
