Opening a restaurant in Texas means navigating three separate permit processes — building, fire, and health — that run on different timelines and involve different agencies. Miss the coordination and you'll be paying rent on a finished space you can't legally open.

This guide covers what's required, who reviews it, and how to keep all three tracks moving simultaneously.

Why Restaurants Are More Complex Than Other Commercial Projects

Most commercial tenant finish-outs require a building permit and not much else. Restaurants are different because they involve:

• A change of occupancy in most cases (from retail or office to Assembly Group A-2)
• A commercial kitchen with specialized ventilation, plumbing, and fire suppression requirements
• Food service operations regulated by the health department independently of the building department
• Grease management — grease traps or interceptors required by most Texas jurisdictions
• Hood and suppression systems — commercial kitchen hoods require their own permit and inspection in many cities

Each of these triggers a separate review track. The key to a smooth restaurant opening is running them in parallel, not in sequence.

Track 1: Building Permit

The building permit covers the physical construction of your restaurant — walls, ceilings, flooring, electrical, HVAC, plumbing rough-in, and the structural elements of the space.

What you'll need:

• Architectural drawings (floor plan, reflected ceiling plan, elevations, details) — sealed by a licensed architect for most Texas commercial projects
• Mechanical, electrical, and plumbing (MEP) drawings — sealed by licensed engineers
• Site plan
• Energy compliance documentation (COMcheck)
• Texas Accessibility Standards (TAS) compliance documentation

Change of occupancy: If your space was previously retail, office, or another non-restaurant use, you're changing the occupancy classification to Assembly Group A-2. This triggers a review of whether the existing building systems — fire suppression, egress, structural loads — are adequate for the new use. In some cases, upgrades are required. Identify this before you commit to a space.

Timeline: 4–8 weeks for standard plan review in major Texas cities. Expedited review is available for a fee.

Track 2: Fire Department / Fire Marshal Review

Commercial kitchen hood and fire suppression systems require a separate review by the fire marshal in most Texas jurisdictions. This covers:

• Type I commercial kitchen hood (required over cooking equipment that produces grease-laden vapors)
• Ansul or equivalent wet chemical fire suppression system
• Make-up air system
• Fuel connections (gas lines to cooking equipment)

The fire marshal review often runs concurrently with building plan review, but it's a separate submittal with separate fees. Don't assume your building permit covers it.

Hood installation also requires a separate permit and inspection in many Texas cities. Your hood contractor should pull this permit — confirm they're doing so before work begins.

Track 3: Health Department Review

This is the track most restaurant owners underestimate. The local health authority — typically the city or county health department — reviews your restaurant plans independently of the building department. They're evaluating whether your facility can safely prepare and serve food.

What health reviewers look at:

• Kitchen layout and workflow (cross-contamination prevention)
• Equipment specifications (NSF-certified commercial equipment)
• Handwashing stations (number, location, and accessibility)
• Three-compartment sink (required for manual dishwashing)
• Ventilation and hood system
• Food storage (dry, refrigerated, and frozen)
• Plumbing fixtures and floor drains
• Grease trap or interceptor sizing and location
• Restroom facilities for employees and customers

Grease traps: Most Texas jurisdictions require a grease trap or grease interceptor for food service establishments. Sizing requirements vary by jurisdiction and by the type and volume of cooking. Get this right early — grease trap installation is often on the critical path.

Timeline: Health department review timelines vary significantly by jurisdiction. In some Texas cities, health review runs concurrently with building review. In others, health approval must come before or after the building permit. Know your jurisdiction's process.

Pre-opening inspection: Even after your plans are approved, the health department will conduct a pre-opening inspection before issuing your food establishment permit. This inspection verifies that the facility was built as approved and that you have the required equipment, supplies, and procedures in place.

The Coordination Problem

Here's where restaurant projects typically go wrong: the three review tracks are treated as sequential when they should be parallel.

A common mistake is to wait for building permit approval before submitting to the health department. This adds 4–8 weeks to your timeline for no reason. Both submittals can go in simultaneously.

Similarly, the hood contractor's permit is often pulled late — sometimes after the hood is already installed, which creates inspection problems.

The right sequence:

1. Prepare complete construction documents (architectural + MEP)
2. Submit to building department, fire marshal, and health department simultaneously
3. Respond to comments from all three tracks as they come in
4. Coordinate hood contractor permit with fire marshal review
5. Schedule pre-opening health inspection as construction nears completion
6. Obtain Certificate of Occupancy and food establishment permit before opening

City-Specific Considerations

Houston: No zoning ordinance, but deed restrictions and the city's commercial permitting requirements still apply. Houston's Permit Center handles building review; the Houston Health Department handles food service. Houston also has specific grease trap requirements enforced by the city's Public Works department.

San Antonio: The Development Services Department (DSD) handles building permits. Bexar County Public Health handles food service permits for establishments in unincorporated areas; the City of San Antonio Metropolitan Health District handles those within city limits.

Austin: Austin's Development Services Department handles building permits. Austin Public Health handles food service. Austin has specific requirements around outdoor dining and food truck operations that differ from brick-and-mortar restaurants.

Dallas: Dallas Development Services handles building permits. Dallas County Health and Human Services handles food service for county areas; the City of Dallas handles those within city limits.

Victoria: The City of Victoria Development Services handles building permits. The Victoria County Public Health Department handles food service permits. As a Crossroads-based firm, Permit Guru has direct familiarity with Victoria's process.

Common Mistakes That Delay Restaurant Openings

Underestimating the health department timeline. Health review is not a rubber stamp. Reviewers have specific requirements, and comment rounds are common. Start this process as early as possible.

Wrong equipment specifications. Health departments require NSF-certified commercial equipment. Residential-grade equipment — even high-end residential — is not acceptable. Specify commercial equipment in your plans from the start.

Grease trap sizing errors. Undersized grease traps get flagged in health review and may require redesign. Get the sizing right the first time.

Not accounting for TAS review. Texas Accessibility Standards review is a separate process in many jurisdictions. It runs on its own timeline and must be complete before your CO is issued.

Starting construction before permit issuance. Stop-work orders on restaurant projects are particularly costly because they affect multiple contractors simultaneously.
