Restaurant Buildouts · San Jose
Restaurant Contractor in San Jose
From downtown and Santana Row to The Alameda and East San Jose — health-department-ready kitchens and dining rooms, opened on the date you put on the invitation.
San Jose is the Bay Area's biggest restaurant market and its most varied: fast-casual on San Carlos and Santana Row, full-service downtown and on The Alameda, ghost kitchens in North San Jose, and dense, diverse concepts across Berryessa and East Side corridors. Every one of them lives or dies on the same construction realities — grease capacity, hood routing, gas and power, and a county health inspector who reads every surface.
We build restaurants the way San Jose operators need them built: the space evaluated before the lease is signed (where most six-figure surprises hide), City of San Jose building permits filed through SJePermits while County Environmental Health plan check runs concurrently, equipment coordinated with trades, and inspections scheduled like the revenue milestones they are.
Whether you're taking over a second-generation restaurant on East Santa Clara Street or converting raw retail in a new mixed-use podium, the goal is one number: your open date — and a kitchen that passes health, fire, and building the first time.
Permits & health in San Jose
Two agencies, run in parallel: City of San Jose Building Division (SJePermits portal; 200 E. Santa Clara St.) for building, mechanical, electrical, plumbing, and fire, and the County of Santa Clara Department of Environmental Health for the food-facility plan check (finishes, sinks, refrigeration, grease). Second-generation restaurant spaces with existing hood and grease infrastructure clear far faster — which is exactly why a pre-lease site review pays for itself many times over.

San Jose Restaurant Construction FAQs
How much does a restaurant buildout cost in San Jose?+
In 2026, $150–$300/sq ft for second-generation restaurant spaces and $300–$500+/sq ft to convert non-restaurant space. A typical 2,500 sq ft buildout runs $600K–$1.1M including kitchen equipment. The single biggest cost driver is the lease you choose — specifically whether it already has grease and hood infrastructure sized for your menu.
Do you handle the Santa Clara County health department?+
Completely. We submit the food-facility plan check to the County of Santa Clara Department of Environmental Health, build finishes and coving to their standards, answer corrections, and walk the pre-opening inspection with you — concurrent with City of San Jose building permits.
What is a grease interceptor and why does it matter so much in San Jose?+
It's a 750–1,500 gallon tank that captures grease before the sewer, required for nearly all cooking concepts. If your San Jose space lacks one sized for your menu, installation means cutting the floor slab or trenching the parking lot — $25K–$80K. It's the first thing we check in a pre-lease site review.
Can you look at a San Jose space before I sign the lease?+
Always — it's the highest-leverage hour in the whole project. Ten minutes with the hood path, grease capacity, gas/power, and ADA tells us whether your buildout is $200/sq ft or $400/sq ft, and that number belongs in your lease negotiation.
How long does restaurant construction take in San Jose?+
From lease signing: roughly 6–10 weeks for design and health plan check, permits concurrent where possible, and 8–16 weeks of construction — 6–10 months total for most full conversions. Second-generation spaces with sound infrastructure run faster.
