The permits a Santa Clara County restaurant needs
- County health (DEH) food-facility plan check + health permit — the food-safety approval, handled by the county, not the city.
- City building permit — the construction itself, including mechanical, plumbing, and electrical sub-permits.
- Type I hood + UL-300 fire suppression — ventilation and fire approvals for grease-producing cooking.
- Grease interceptor / sanitary-sewer sign-off — sizing and connection approved by the local sanitation district.
- Fire department review — occupancy, exits, suppression, and extinguishers.
- Business license — from the city you operate in (San Jose, Sunnyvale, Santa Clara, and so on).
- ABC license — state Alcoholic Beverage Control, if you serve beer, wine, or spirits.
- Sign permit, and sometimes a conditional use permit (zoning), depending on the space and city.
The sequence that protects your opening date
The order matters more than any single permit. Before you sign the lease, verify zoning allows a restaurant and that the space's hood, interceptor, and utilities are usable — the cheapest risk you'll ever buy down. At design freeze, submit county health plan check and the city building permit in parallel, and order long-lead equipment (hoods, walk-ins) immediately.
Run fire review alongside building, start the ABC application early (it's the long pole for alcohol — allow a couple of months), and schedule the DEH pre-opening inspection only once finishes and equipment are in. Sequential operators lose months; parallel filing is how you open inside a free-rent window.
County health (DEH) plan check, in detail
- Three-compartment sink, plus separate prep, hand, and mop sinks per plan.
- Smooth, cleanable, non-absorbent finishes: floors with integral coving, washable walls and ceilings.
- Refrigeration and hot/cold holding sized to the menu.
- Handwashing stations placed per code throughout the kitchen and prep areas.
- Grease management and an approved dishwashing and sanitizing setup.
- A pre-opening inspection by DEH before you can operate.
Building, fire, and the hood
The city building permit covers the construction and its mechanical, plumbing, and electrical scope. Any grease-producing cookline needs a Type I hood with make-up air and a UL-300 wet-chemical fire-suppression system, inspected and tagged. The fire department reviews occupancy load, exits and exit signage, suppression, and extinguishers.
The grease interceptor is approved by the local sanitation district and sized to your fixture and fryer load — confirm it during due diligence, because an undersized or missing interceptor is the classic mid-project surprise that costs $20K–$70K and weeks.
Business license and ABC
You'll need a business license from the city you operate in and a seller's permit from the state for sales tax. If you serve alcohol, the state ABC license is the longest-lead approval on the list — start it early, because it runs on its own timeline independent of construction and can gate your opening even when the buildout is done.

Frequently Asked Questions
Who issues a restaurant health permit in Santa Clara County?+
The county Department of Environmental Health (DEH) handles food-facility plan check and the health permit countywide. The city you're in handles the building permit and business license. They're separate approvals — file the health and building ones in parallel.
What's the longest-lead permit for opening a restaurant?+
For alcohol service, the state ABC license — it commonly takes a couple of months and runs independently of construction, so start it early. On the construction side, anything requiring a new grease interceptor or Type I hood adds the most schedule, which is why second-generation spaces open faster.
Do I need a permit for a second-generation restaurant space?+
Almost always, yes. Even reusing a former restaurant, any change to the kitchen layout, hood, plumbing, or electrical triggers building and health plan check. The advantage of second-gen is reused infrastructure and a faster path — not skipping permits.
Can I open before the ABC license comes through?+
You can open the food side once health and building sign off, but you cannot serve alcohol until ABC issues. Many operators open food-first and add alcohol service when the license lands — but plan the timeline so it doesn't undercut your launch.
