Whether you're opening a restaurant, building out a retail space, or converting an office into a clinic, the first question is almost always the same: how long is this going to take? The honest answer is that it depends — but not in a vague way. Bay Area build-out timelines follow patterns that are predictable once you understand the moving parts.
After completing 50+ tenant improvement projects across San Francisco, Oakland, San Jose, and the wider Bay Area, we've mapped out what a realistic timeline looks like at each phase — and where the delays actually come from.
The Four Phases of Every Commercial Build-Out
Every project moves through four sequential phases: pre-design and feasibility, design and construction documents, permitting and approvals, and construction. Skipping or compressing the early phases almost always inflates the later ones.
Phase 1: Pre-Design and Feasibility (1-2 Weeks)
Before any design work begins, your architect should walk the space, review the lease, and assess code feasibility. This is where deal-breakers surface — no path for kitchen exhaust, insufficient electrical service, a change-of-use that triggers seismic upgrades, or an ADA path-of-travel issue that could consume 20% of your construction budget.
A 2-hour pre-lease feasibility review costs under $1,000. Discovering a deal-breaker after signing can cost $50,000 or more. We've seen it happen dozens of times.
This phase also includes zoning verification, occupancy classification review, and a preliminary conversation with the building department if the project involves a change of use. In San Francisco, a Change of Use triggers Planning Department review on top of the Building Department — adding weeks or months that many owners don't anticipate.
Phase 2: Design and Construction Documents (3-6 Weeks)
This is where your architect translates the concept into permit-ready drawings. For a straightforward retail or office build-out, this can take as little as 3 weeks. A full-service restaurant with kitchen engineering, MEP coordination, and Title 24 energy compliance typically requires 5-6 weeks.
- Light retail/office fit-out: 2-3 weeks for permit-ready drawings
- Fast-casual restaurant or cafe: 3-4 weeks including health department plans
- Full-service restaurant: 5-6 weeks with kitchen engineering, Type I hood coordination, and MEP
- Change of use or adaptive reuse: 4-8 weeks depending on structural and seismic scope
During this phase, your architect should be coordinating with mechanical, electrical, and plumbing engineers simultaneously — not sequentially. Parallel coordination is one of the biggest time-savers in the entire process. We also prepare Title 24 energy compliance documentation, NRCC forms, and health department submittals during design so they're ready to submit alongside building permits.
Phase 3: Permitting and Approvals (4-16 Weeks)
This is where most projects stall — and where Bay Area timelines diverge dramatically by city. Permitting is not a single review. It often involves Building Department plan check, fire marshal review, health department approval (for food service), Planning Department review (for changes of use or signage), and accessibility compliance review.
Here's what we see across the cities we work in most frequently:
Permitting Timelines by City
San Francisco is the most complex jurisdiction. A restaurant TI typically takes 8-16 weeks through plan check, with DBI processing times varying by season and staffing. Over-the-counter permits are available for minor work (cosmetic, low-voltage electrical) and can be issued same-day. For larger projects, expect 2-3 rounds of plan check comments. Health department review runs concurrently if you submit simultaneously — saving 4-6 weeks compared to sequential submission.
Oakland has been proactively streamlining small business permitting. Restaurant and retail TI permits typically take 6-12 weeks, with the city offering grants and early coordination programs that can accelerate the process. Oakland's building department is generally responsive, but projects in historic districts or requiring design review can add 4-8 weeks.
San Jose and the South Bay offer express permit options for straightforward projects, often processing in 3-4 weeks. Tech campus build-outs and life science conversions benefit from the region's high-volume review infrastructure. Palo Alto requires design review for projects in the downtown zone, which can add 6-12 weeks depending on the planning commission calendar.
Berkeley requires a use permit for most commercial changes, with design review adding potential months for visible exterior modifications. Walnut Creek and the Tri-Valley cities typically process in 4-6 weeks, with design review required in downtown core areas.
Phase 4: Construction (4-20 Weeks)
Construction duration depends on scope, contractor availability, and how well the design documents were prepared. Incomplete drawings generate RFIs (Requests for Information) that stall work, create change orders, and push timelines. This is why investing in thorough design documents pays for itself during construction.
- Light retail refresh (paint, flooring, fixtures): 2-4 weeks
- Standard office build-out (walls, electrical, HVAC): 6-10 weeks
- Fast-casual restaurant or cafe: 8-12 weeks
- Full-service restaurant with kitchen: 12-20 weeks
- Full gut renovation or change of use: 16-24 weeks
The most common construction delays we see are contractor scheduling conflicts (Bay Area contractors are consistently booked 4-8 weeks out), inspection scheduling backlogs (San Francisco inspections can take 1-2 weeks to schedule), equipment lead times (commercial kitchen equipment can take 8-12 weeks to arrive), and change orders from incomplete design documents.
Total Timeline: What to Actually Expect
Combining all four phases, here are realistic total timelines from lease signing to opening day:
- Light retail or office fit-out: 3-5 months
- Fast-casual restaurant or cafe: 4-7 months
- Full-service restaurant: 6-12 months
- Medical or dental clinic: 5-9 months
- Change of use or adaptive reuse: 8-18 months
Every week of delay after lease signing costs you rent without revenue. A 2,500 SF space at $4/SF/month means $10,000 per month in dead rent during build-out. That's $30,000-$60,000 in carrying costs for a typical restaurant project.
Three Ways to Shorten Your Timeline
First, get your architect involved before you sign the lease. A pre-lease feasibility check identifies problems before they become expensive. We offer this as a standalone service — it typically pays for itself many times over.
Second, submit permits in parallel. Building permits, health department plans, and fire marshal reviews can often run simultaneously instead of sequentially. This requires an architect who understands multi-agency coordination and prepares all submittals during the design phase — not after.
Third, negotiate a rent abatement period in your lease that covers the realistic build-out timeline — not the optimistic one. Landlords in the Bay Area are accustomed to this, and it protects you from paying rent on a construction zone.
The Bottom Line
Bay Area commercial build-outs take longer than most business owners expect — but they don't have to take longer than necessary. The projects that finish on time are the ones that invested in thorough pre-design, prepared complete permit documents, and coordinated agencies in parallel from the start.
If you're planning a build-out in San Francisco, Oakland, or anywhere in the Bay Area, we can give you a realistic timeline specific to your project, your space, and your city — before you commit to a lease or a contractor.
