Restaurant permit delays: why plan review stalls and how to submit once

A restaurant permit is rarely one permit. It is a building permit, a health department plan approval, a fire permit for the hood suppression system, a grease interceptor approval and usually a sign permit, each reviewed by different people on different clocks. The restaurant permit delays you can control start before anyone opens the file: the package is incomplete, or it disagrees with itself. Here is what each reviewer checks, what published review times look like, and how to submit a set that clears early.

Which permits and approvals does a restaurant need?

More than a retail tenant does. Expect a building permit, a separate health department plan review, a fire permit for the hood suppression system, a grease interceptor approval from plumbing or the sewer utility, and usually a sign permit. A change of use can pull zoning and fire back in. The list varies by jurisdiction, so confirm it with each plan reviewer before you submit.

Building permit

The building department reviews architecture, structure, energy, egress, accessibility and the MEP (mechanical, electrical and plumbing) sheets, usually as a tenant improvement (TI) permit in a second-generation space. It is the permit everyone tracks, which is why the others get forgotten.

Health department plan review

The health department is a separate agency with a separate queue. The FDA Food Code, a model code offered for adoption by state and local jurisdictions, says a permit applicant must submit "properly prepared plans and specifications for review and approval before" building a food establishment, converting a structure into one, or remodeling one when the regulator decides plans are needed (Section 8-201.11) ¹. Section 8-201.12 lists what goes in: the menu, expected food volumes, layout, mechanical schematics, finish schedules, and equipment types, manufacturers, model numbers, locations and installation specifications ¹. In other words, the health reviewer is checking your equipment schedule.

Hood, exhaust and fire suppression

Grease-producing cook lines need a hood, grease duct, makeup air and a fire suppression system. Mechanical reviews the exhaust and makeup air, and the fire department may permit the suppression system separately. Castle Rock Fire and Rescue in Colorado, for example, requires a fire permit for every new commercial cooking suppression system and reviews plans against the International Fire Code, NFPA 17A and NFPA 96, the National Fire Protection Association's commercial cooking standard ². Suppression drawings are usually laid out around a specific hood, so a late hood selection means a late fire submittal.

Grease interceptor and plumbing

Drains carrying fats, oils and grease (FOG) run to a grease interceptor, and the sewer utility often wants its own say. In Austin, the water utility's Industrial Waste group reviews building plans for pretreatment devices, and its page is blunt: "Industrial Waste review is separate from and in addition to plumbing review." ³ Sizing follows the fixtures that drain to it, so moving a three-compartment sink or adding a dish machine can reopen that approval.

Accessibility

Accessibility review covers restrooms, counters, seating and the route from parking to the door. On a remodel, the Americans with Disabilities Act (ADA) can also pull in the path of travel to the altered area, including restrooms. Department of Justice rules treat that path-of-travel spending as disproportionate once it exceeds 20% of the cost of the alteration to the primary function area ⁴. A second-generation site with old restrooms can carry scope nobody budgeted. This is not legal advice, and local codes may add requirements; have your architect check it in due diligence.

Signage and change of use

Exterior signs usually need their own permit plus landlord approval. They rarely hold up the building permit, but they can hold up opening if nobody submits them until the end.

Turning retail or office space into a restaurant is often a change of use or occupancy. More people per square foot means the reviewer rechecks exits, restroom fixture counts, fire separations and sometimes sprinklers. Settle early whether those upgrades are yours or the landlord's, and put the answer in the landlord work letter.

How long does restaurant plan review take?

Weeks per review cycle, per agency, and the clock usually starts when the application is accepted as complete, not when you upload it. Austin says commercial review takes 7 to 25 business days depending on application type ⁵. Seattle targets 2 to 4 weeks for most tenant improvements and 8 to 12 weeks for complex projects, including larger ones ⁶. Every comment round adds another cycle.

Austin lists 10 business days for a remodel of 25,000 square feet or less ⁵. In Seattle, routing to other departments automatically bumps a project out of the fastest review group ⁶.

The health department runs its own clock. Public Health - Seattle & King County says that, because of current volumes, an initial food plan review may take up to 8 to 10 weeks ⁷. Building and health reviews can run in parallel, but only if both packages are ready on the same day.

8-10 weeks

:::

Even the law written to speed this up starts the clock at "complete." California's AB 671, approved in October 2025, creates an optional path for restaurant TIs: a qualified licensed architect or engineer certifies the plans at the applicant's expense, and the building department then has 20 business days from a complete application to approve or deny, or the plan is deemed approved, and 10 business days per resubmittal ⁸. It excludes fast food restaurants as the state Labor Code defines them, and other limits apply, so many quick-service chains may not qualify ⁸. Ask your reviewer and counsel.

Published times are targets, not promises. Check current numbers when you build the schedule and plan for at least one comment round. The restaurant opening timeline shows where permitting sits against lease, design, equipment and construction.

Why do restaurant plans get rejected or sent back?

Usually because the package is missing something or contradicts itself, not because the design is wrong. Missing sheets, missing agency forms and drawings that disagree with each other all generate comments. Each comment means a revision, a resubmittal and another turn in the queue.

Typical contradictions look like this:

• An equipment schedule that calls for a three-phase fryer while the panel schedule shows a single-phase circuit.
• A dish machine or three-compartment sink with no matching drain, indirect waste or grease routing on the plumbing sheets.
• A hood length on the foodservice plan that doesn't match the mechanical exhaust and makeup air design.
• A health set built from an older equipment list than the building set.
• Existing conditions copied from the landlord's old drawings instead of verified in the field.
• A dining room seat count that grew after restroom fixture counts were set.

None of these are design failures. They are coordination failures, and reviewers are paid to find them.

What does each resubmittal cycle cost you?

Time first, then money. Every round goes back into a queue, and some cities charge for it: Austin charges a fee for each update submission beginning with the second update ⁵. Meanwhile the lease clock keeps running, the general contractor (GC) holds a crew and equipment deliveries get pushed.

Comments compound across agencies: a health comment that moves a sink changes a plumbing sheet the building reviewer already approved. One coordinated revision that answers every open comment beats three partial ones.

How do you submit a complete package the first time?

Coordinate before you submit, not after the first comment letter. Confirm every agency, form and fee with the reviewers, freeze the menu and equipment list, check the foodservice plan against the MEP sheets line by line, and issue the building and health packages from the same revision.

In the software, that review is foodservice drawing coordination: the kitchen plan sits beside the architectural, utility and field files.

What should multi-unit teams standardize across sites?

Standardize the package, not the assumption that every city reads it the same way. Keep the prototype's equipment schedule, hood and utility loads in one coordinated set, then adapt it to each site's verified conditions and local amendments. Track every agency review as its own item with an owner and a date, so a missing grease or fire approval shows up before it holds the opening.

Keep a sheet per jurisdiction with agencies, forms, fees and reviewer contacts, and log comments by type. If the same comment shows up in three cities, fix the prototype and stop paying for the same restaurant permit delays site after site.

What does the On-Time Permit Submission Guarantee cover?

Our part, and only our part. At kickoff we agree the permit submission date and the delivery dates for every design deliverable that feeds it, and the guarantee is that our drawings are ready on that date. It does not cover how long the city or health department takes to review them, and it is not an opening date. No one can honestly promise either.

The guarantee comes with the On-Time Rollout Partnership, along with the scan, as-built model, 3D test fit and foodservice + MEP coordination for every restaurant. For everything else, rules vary by jurisdiction; confirm with your plan reviewer.
