If you're signing your first retail lease, the most common question I get is some version of: Okay, when can I actually open?'
Most first-time tenants underestimate timelines because they're imagining the construction phase only. In real life, the clock starts ticking the minute you sign the lease and the slow parts are usually design, permitting, and waiting on other people's calendars.
Here's the good news: if you plan this like a project manager (not like a dreamer), you can set a timeline you can actually hit and you'll know early whether you're on track or heading for a soft launch that turns into a three-month delay.
The quick answer: simple refresh' vs. real build-out'
As a rough benchmark, many tenant improvement (TI) projects land in a range of about 8 16 weeks from design completion to occupancy, with cosmetic work sometimes closer to 4 8 weeks of construction and complex shell build-outs running 4 6 months or longer (EB3 Construction).
That's directionally useful but it's not a lease-to-opening timeline, because you still have to (a) design the space, (b) get permits approved, (c) order long-lead items, and (d) pass inspections.
Step 1 (Week 0 1): Before you sign, get your time math straight
Before you sign a lease, you should know whether you're walking into a paint + signage + fixtures' job or a new HVAC, new electrical, new plumbing' job. That difference is the entire timeline.
- Ask the landlord what condition you're getting: second-generation (already built out for a prior tenant) is often faster than a cold/dark shell.
- Ask what drawings they already have: if there are base building plans, MEP as-builts, and an existing sprinkler plan, you're not starting from zero.
- Ask who controls the approvals: in many centers, you need landlord review before the city even sees your drawings. That landlord review can quietly take weeks.
Also: if your business model is seasonal (holiday retail, summer concepts), don't set your opening date based on optimism. Set it based on your slowest plausible path, then try to beat it.
Step 2 (Week 1 7): Design + engineering (the part people forget)
For most small retail tenants, the design phase is where timelines either get protected or get wrecked.
A typical sequence looks like:
- Schematic layout: you and the designer decide what goes where (sales floor, back of house, restroom, fitting rooms, storage).
- Permit-ready drawings: you need the level of detail a building department will accept, and that usually means some combination of architectural plus mechanical/electrical/plumbing (MEP) sheets if you're touching those systems.
One contractor's breakdown puts schematic planning around 1 2 weeks and permit-ready drawings/MEP engineering around 4 6 weeks for a typical TI set (EB3 Construction).
My practical advice: treat design like a deadline-driven phase, not an open-ended creative exercise. Every week you delay picking finishes, equipment, and layout decisions is a week you're paying rent later with no revenue.
Step 3 (Week 4 16+): Permits and plan review (the biggest wildcard)
Permitting is where retail timelines go to die because it's not just one permit, and it's not just one reviewer.
Most TI projects need multiple permits (building, plus trades like electrical/plumbing/mechanical, and often fire protection) (Permit Place).
Here's what makes this phase tricky: review times vary massively by city. One permitting guide summarizes typical first-round review times ranging from about 10 15 business days in Phoenix to 45 90 business days in New York City, with total time-to-permit often stretching further once you include back-and-forth corrections (Permit Place).
What I tell clients: assume you'll get corrections. Budget time to respond quickly, because every day you sit on corrections is a day added to your opening date.
Step 4 (parallel): Long-lead items (order early or you'll wait later)
Even if your permit is moving, long-lead items can quietly blow up your schedule. Think: custom millwork, certain lighting packages, specialty flooring, HVAC equipment, and anything imported or made-to-order.
It's common to see custom millwork quoted at 8 12 weeks from order to delivery (EB3 Construction).
And in 2026 specifically, the macro backdrop still matters: construction input costs have been running meaningfully above year-ago levels, and trade policy and energy prices have been cited as ongoing cost drivers which tends to translate into more procurement risk and fewer easy' substitutions late in the job (Associated General Contractors of America; JLL).
If you want one tactical rule: order anything that can hold up inspections as early as you responsibly can. If your electrical panel upgrade or HVAC unit is delayed, you can't finish around it.'
Step 5 (Week 8 24+): Construction (what you expected to be the whole project)
Construction duration depends on what you're doing:
- Cosmetic refresh: paint, flooring, basic fixtures often around 4 8 weeks of construction time (EB3 Construction).
- Real build-out: new walls + meaningful MEP work commonly multiple months, and a cold/dark shell can run 4 6 months or longer depending on complexity (EB3 Construction).
If you're in a multi-tenant retail center, add another layer: work-hour restrictions, deliveries through shared loading, noise rules, and coordination with property management can make a four-week job feel like eight.
Step 6 (the last mile): Inspections, punch list, and Certificate of Occupancy
The last mile is where a lot of teams get blindsided because they're basically done', but they're not legally allowed to open yet.
Most jurisdictions require inspections at milestones (rough-in, above-ceiling, fire, final) and then a final sign-off before you can occupy. One TI timeline breakdown notes that final inspections and closeout can sometimes happen in a matter of days once everything is actually ready (EB3 Construction).
In practice, I recommend building buffer here for scheduling (inspectors have calendars too) and for punch-list items that must be fixed before final approval.
A simple planning template I use with first-time retail tenants
If you want a realistic plan, I like to build the schedule backwards from your desired opening date:
- Pick your target opening week (and decide if you need a soft opening).
- Back up your construction duration (4 8 weeks for refresh; 12 24+ weeks for real build-out).
- Add permitting time based on your city's reality not a national average.
- Add design/engineering time with hard decision deadlines.
- Overlay long-lead procurement for anything that blocks rough-in or final inspections.
And before you commit to a budget, I always tell tenants to price the buildout early. A rough estimate from BuildoutIQ won't replace contractor bids, but it can quickly tell you whether your plan is in the right universe before you sign a lease that starts the rent clock.
Bottom line
The retail build-out timeline isn't one number. It's a chain: design permits procurement construction inspections. The best way to open on time is to treat the first three links as seriously as the fourth.
If you're early in the process, focus on two things this week: (1) get the right team (designer + GC) lined up, and (2) get a real permitting reality-check in your city before you promise an opening date on Instagram.
