Building Permits in Houston

Houston is the largest U.S. city without traditional zoning, but that does not mean you can build without a permit. The Houston Permitting Center issues building permits and enforces a locally adopted building code (based on the International Building Code and International Residential Code) for nearly all construction, alteration, and repair work inside the city limits.

The Houston quirk: There is no zoning, but there is a full building code, a platting process, subdivision regulations (Chapter 42), and privately enforced deed restrictions. Skipping any of these can get your project stopped mid-construction — or sued by neighbors — even if you have a permit.

Who Issues Permits

Houston consolidates permitting at the Houston Permitting Center at 1002 Washington Avenue, which brings together three divisions under one roof:

• Building Code Enforcement — residential and commercial permits, plan review, and inspections (structural, electrical, mechanical, plumbing). Phone: 832-394-9494.
• Office of the City Engineer — floodplain management, right-of-way permits, street cuts, stormwater, and telecommunications.
• Infrastructure & Development Services — developer contracts, impact fees, and water/sewer connections.

Platting and subdivision review are handled separately by the Planning & Development Department through the PlatTracker system.

When You Need a Permit

You generally need a permit in Houston for:

• New construction, additions, and accessory structures (including garage apartments / secondary dwelling units)
• Structural alterations, load-bearing wall changes, and foundation work
• Electrical, plumbing, mechanical (HVAC), and gas line changes
• Roofing replacement and new window/door openings in exterior walls
• Swimming pools and certain fences and retaining walls
• Work in the floodplain (Houston has extensive FEMA-mapped flood zones)
• Demolition of any habitable structure

Minor cosmetic work — painting, floor coverings, cabinetry without plumbing/electrical changes — is typically exempt. When in doubt, use the Houston Permitting Center's Project Planner tool or call 832-394-9494 before starting.

Permit Costs

Houston permit fees are set by the city's annually updated fee schedule and are calculated from a combination of:

• Building permit fee — scales with project valuation
• Plan review fee — charged for commercial and most residential plan-review work
• Trade permit fees — separate electrical, plumbing, and mechanical permits
• Inspection fees — by discipline
• Impact fees / utility connection fees — for new construction or added capacity
• Floodplain review fees — if the property is in a FEMA-mapped flood zone

Because rates change annually, do not rely on third-party estimates. See the Houston Permitting Center for current rates and use iPermits and the fee calculators to estimate your project.

Typical Timeline

Texas has no statewide building code and no statewide ministerial-review deadline like California's 60-day ADU rule, so Houston's own queue and correction cycles drive timing.

The Process

1. Check deed restrictions and HOA covenants. The city does not screen for these; you must.
2. Confirm platting. Use PlatTracker to check that your lot is properly platted under Chapter 42. If not, plat first.
3. Pre-submittal prep. Verify lot development standards (minimum lot size, setbacks, parking, tree and shrub rules, building lines) and whether the property sits in a FEMA flood zone.
4. Prepare plans — stamped by a licensed Texas architect or engineer where required by the building code.
5. Apply online through iPermits and upload plans into ProjectDox (Houston's electronic plan review portal).
6. Plan review — Houston assigns reviewers across structural, mechanical, electrical, plumbing, and storm disciplines.
7. Corrections — address comments and resubmit until approved.
8. Permit issuance — pay remaining fees and print/download the permit.
9. Inspections — schedule by discipline at each construction phase.
10. Final inspection and Certificate of Occupancy where applicable.

Inspections

Houston's Building Code Enforcement division runs inspections across structural, mechanical/HVAC, electrical, and plumbing disciplines, plus multi-family habitability, sign administration, occupancy, and special inspections (concrete, welding, high-strength bolting). Typical residential inspection stages include:

• Foundation / footings
• Underground plumbing and electrical
• Framing
• Insulation
• Rough electrical, plumbing, and mechanical
• Drywall
• Final

Schedule inspections through the Houston Permitting Center portal or by calling 832-394-9494.

Common Reasons for Denial or Delay

• Lot is not properly platted under Chapter 42
• Plans don't meet the currently adopted building, electrical, plumbing, or mechanical code
• Missing engineer stamp, wind-load calculations, or foundation design
• Floodplain elevation requirements not met (a common issue in Houston)
• Chapter 42 lot development standards not satisfied (setbacks, lot size, parking, tree rules)
• Missing utility clearances (water, sewer, power)
• Project conflicts with a private deed restriction flagged by a neighbor (note: the permit center does not catch these — your neighbors or the Legal Department will)

Deed Restrictions: The Hidden Second Layer

Houston is unusual in that a permit from the city is not the final word on whether your project is legal. Deed restrictions — private covenants recorded against the land — can cap building height, restrict commercial use, require specific setbacks, or prohibit secondary dwelling units even where the city code allows them. The City of Houston's Legal Department actively enforces recorded deed restrictions, and neighbors can sue to enforce them as well. Check your title work and any HOA CC&Rs before you file for a permit.
