How Long Does a Commercial Buildout Take? Timeline by Space Type
A retail buildout can be done in 8–14 weeks. A restaurant takes 4–10 months of construction plus 2–4 months of design. Here's a realistic timeline breakdown by space type so you can plan your opening date.
One of the most common mistakes entrepreneurs make when planning a commercial buildout is underestimating the timeline. It's easy to see a 2,000 square foot empty shell and think 'six weeks and we're open.' The reality: construction is typically the fastest phase. Permits, inspections, equipment lead times, and health department review are what actually control your opening date.
Here's an honest, phase-by-phase timeline for the most common commercial buildout types.
Phases of a Commercial Buildout
- Phase 1: Site selection and lease negotiation (2–8 weeks)
- Phase 2: Design and architectural drawings (4–12 weeks)
- Phase 3: Permit review and approval (2–16 weeks depending on jurisdiction and project complexity)
- Phase 4: Construction (4–20 weeks)
- Phase 5: Inspections, equipment installation, and final health department sign-off (2–6 weeks)
- Phase 6: Soft open / staff training (2–4 weeks)
Timeline by Space Type
| Space Type | Design + Permits | Construction | Total Realistic Timeline |
|---|---|---|---|
| Simple retail (cosmetic only) | 4–6 weeks | 4–8 weeks | 2–3 months |
| Mid-range retail (new MEP) | 8–14 weeks | 8–12 weeks | 4–6 months |
| Coffee shop / café | 8–16 weeks | 10–16 weeks | 5–8 months |
| Fast casual restaurant | 10–18 weeks | 12–20 weeks | 6–9 months |
| Full-service restaurant | 12–24 weeks | 16–24 weeks | 8–12 months |
| Medical / dental office | 10–20 weeks | 12–18 weeks | 6–10 months |
The Permit Phase: The Most Underestimated Delay
In most markets, the permit phase is the biggest source of timeline surprises. Cities like Los Angeles, New York, San Francisco, and Chicago have notoriously slow permit offices — 12–20 week wait times for restaurant plan checks are not uncommon. Even in faster markets, a single incomplete submittal can add 4–8 weeks to the review process.
- Health department plan review: 4–12 weeks (separate from building permits)
- Building permit review: 2–10 weeks
- Fire department review (for hood suppression): 2–6 weeks
- Structural engineering review (if applicable): 2–4 weeks additional
- Expedited review options: available in some cities for 2–3× fee
Construction Phase: What Actually Takes Time
Critical path items to track:
Once permits are in hand, construction timelines are driven primarily by MEP rough-in complexity and specialty trades. Framing and drywall are fast. It's the plumbers, electricians, and HVAC crews who set the pace — they're in highest demand, and scheduling them in sequence takes coordination.
- Hood system installation and rough-in (often on a 6–10 week lead time from order to install)
- Walk-in cooler delivery and installation (4–8 week lead time)
- Custom millwork and cabinetry (6–12 week fabrication lead time)
- Gas line work (requires gas company approval and inspection)
- Floor slab work for floor drains (must be done before flooring)
Equipment Lead Times: The Hidden Timeline Risk
Commercial kitchen equipment lead times have normalized somewhat since the supply chain disruptions of 2022–2024, but specialty items still take 6–16 weeks. Ordering equipment before your permit is approved is common practice — you're betting on permit approval, but the alternative (waiting until permits are in hand) adds 2–4 months to your timeline.
Walk-in coolers and custom equipment have the longest lead times. Standard commercial refrigerators and cooking equipment from major manufacturers (Hobart, True, Manitowoc) are typically available in 2–4 weeks from distributors with stock.
How to Plan Your Opening Date Realistically
Take your most optimistic construction timeline estimate. Add 30% for delays. Add the full permit phase estimate (use your jurisdiction's average, not the best case). Then back-calculate from there to determine when you need to have your architect engaged, your drawings submitted, and your equipment ordered.
A useful rule of thumb: if you want to open a full-service restaurant, you should be signing your lease 10–14 months before your target opening date. For a coffee shop, 6–9 months. For simple retail, 4–6 months. Plan backwards, not forwards.
Start the Planning Before You Need It
The single best thing you can do to compress your timeline is to do your preliminary planning before you've signed a lease. That means knowing your layout, equipment needs, and rough cost estimate before you're on the clock. Landlords grant lease commencement dates, and every week you spend getting organized after signing is a week of rent paid without income.
Red Flags That Will Blow Your Timeline
Even with careful planning, certain situations reliably cause major delays. Know these patterns before you're in the middle of them.
- Incomplete permit submittals: A single missing sheet — fire sprinkler layout, structural calculations, equipment spec sheet — triggers a 'correction notice' that restarts your review clock. Submit complete documents, every time.
- Contractor scheduling gaps: If you sign the lease and immediately need to start construction, but your GC can't mobilize for 6 weeks, you're paying rent on an empty shell. Engage your contractor before lease signing, not after.
- Equipment back-orders: Ordering a popular walk-in cooler or commercial range the week you pull permits is a gamble. Some items are on 10-14 week lead times. Order critical equipment as soon as your permit is submitted, not when it's approved.
- Change orders mid-construction: Every significant change order resets the GC's scheduling and adds 2–4 weeks minimum. Lock in your design before breaking ground.
- Landlord-caused delays: Landlord approval delays for contractors, materials, or scope changes can be significant — especially with institutional landlords who have internal review committees. Negotiate specific approval timelines in the lease.
A realistic commercial buildout timeline isn't pessimistic — it's what gets you to opening day without running out of money. Add your projected rent-commencement date, back out the full timeline, and that's the date by which you need to have your architect engaged and your lease terms locked. If that date is already past, you're behind. Start now.
