How Long a Commercial Buildout Takes — and What Actually Moves Your Date
How Long a Commercial Buildout Takes — and What Actually Moves Your Date
Most operators assume the construction is the risky part of a commercial buildout timeline. It usually isn't. Framing, drywall, paint, and trim run in a known sequence with a known crew count, and a contractor can push them. What moves your opening date is almost always what happens before and around the work: a plan reviewer at a permit desk and a factory building a piece of equipment. Here is how to think about the calendar so you don't sign a lease around the wrong date.
The short version
- A commercial buildout has six phases. Only one of them is actual construction.
- Site walk and estimate expect a site visit within a week, two weeks for the estimate to get back to you, on most interior projects.
- Contract and design move as fast as your decisions do. That part is on you.
- Permitting is the wild card. It's driven by the jurisdiction, not by you or your contractor. Hope for two weeks, expect 4 weeks.
- Long-lead items — rooftop HVAC units, electrical switchgear, walk-in coolers, custom millwork — speciality items can take weeks or even months. Most common items can be ordered in time for the schedule.
- Construction is the phase a contractor controls, and it runs in sequence.
- Punch list and closeout take days, plus final inspections and your certificate of occupancy.
- Protect your date two ways: start permitting early, and order long-lead items the day the scope is set.
The six phases of a commercial buildout timeline
Every interior project — a tenant improvement, a restaurant buildout, a warehouse conversion — moves through the same six phases. What changes is how long each one takes.
| Phase | Typical duration | Who controls it |
|---|---|---|
| Site walk and estimate | Days, not weeks | Your contractor |
| Contract and design finalization | As fast as decisions get made | You |
| Permitting and plan review | Weeks, sometimes more | The jurisdiction |
| Mobilization and long-lead procurement | Runs parallel; gated by factory lead times | Suppliers |
| Construction | 4-12 weeks | Your contractor |
| Punch, final inspections, CO | Days, plus inspector availability | Shared |
Notice that the contractor fully controls two rows. That is the honest picture. A good pre-construction process exists mostly to protect the four rows he doesn't control.
The two things that actually move your date
Permitting and long-lead equipment.
A contractor can add crews, run a second shift, or resequence trades to hold a construction schedule. Nobody can speed up a plan reviewer. Nobody can call a switchgear plant and move up the build slot. Those two items sit outside the job site, and they are the two most common reasons an opening date slips.
You can throw more people at construction. You cannot throw more people at a plan reviewer or a switchgear factory.
So the strategy is simple. Get the permit application in as early as the drawings allow, and place orders for long-lead items the day the scope is set — not the day the schedule needs them on site.
If you have a lease date and no schedule yet, that's the call to make now — a site walk turns the guesswork into a real calendar.
Permitting: driven by the jurisdiction, not by you
Two identical projects in two different counties can have very different review times. Same drawings, same scope, different queue. Some jurisdictions in Metro Atlanta run express or over-the-counter review for straightforward interior work; others do not. Two weeks if everything goes smoothly, four weeks is not surprising, if revisions or resubmissions are required, can take 6-8 weeks.
What you can control: submitting a complete package. Missing details, unstamped drawings, or a scope that doesn't match the drawings all send you back into the queue. A resubmittal often costs more calendar time than the original review.
Long-lead items: order the day the scope is set
Long-lead means anything built to order rather than pulled from a warehouse shelf. On the projects we see most, that list usually includes:
- Rooftop HVAC units and custom air handlers
- Electrical switchgear, panels, and transformers
- Walk-in coolers and freezers
- Commercial kitchen hoods and fire suppression
- Storefront glass and custom doors
- Custom millwork and specialty flooring
The damage from a late order is worse than it looks. If a rooftop unit lands four weeks after the ceiling was ready to close, the ceiling sits open, and every trade behind it — drywall finish, paint, flooring, final clean — slides too.
Where this goes wrong
Signing a lease with a rent-start date before anyone has looked at the space. Rent clock running, permit not filed. It happens constantly.
Treating design as a slow lane. Every week of undecided finishes is a week the permit isn't filed and equipment isn't ordered. Decisions are schedule.
Ordering equipment after permit approval. People wait so they don't buy the wrong thing. Meanwhile the factory queue grows. Order what the scope has already locked in.
Assuming the building is ready for your load. An existing space may not have the power, gas, or grease capacity your operation needs. Finding that out during construction means a new drawing, a new review, and a new lead time.
Forgetting the tail end. Final inspections and the certificate of occupancy are not the same day as "construction is done." Health department, fire marshal, and building final each have their own queue. Each trade and department has their own inspections, finals and the building and fire marsahl for final certificate of occupancy, the "C.O.".
Planning a grand opening off the construction end date. Plan it off the CO date, then add a buffer for training and stocking.
FAQ
How long does a commercial buildout take from lease signing to opening?
It depends far more on permitting and equipment lead times than on the construction itself. The construction phase for an interior project of this size is fairly predictable; the review queue and the factory queue are not. A site walk and a look at your scope is the only way to get a date you can plan around. I'd expect 8-16 weeks from handshake to handshake.
What is the difference between the construction schedule and the project schedule?
The construction schedule covers work on site — demo through punch list. The project schedule covers everything: estimate, contract, design, permitting, procurement, construction, and closeout. When a landlord or a franchisor asks how long the buildout takes, they mean the project schedule. Answer that one.
Can I start construction before the permit is issued?
No — not the permitted scope. Some jurisdictions allow limited early work under a separate demolition or early-start permit, but the rules vary and the penalties for building without a permit are real. Ask your contractor what your specific jurisdiction allows before anyone touches a wall.
What are long-lead items in a commercial buildout?
Anything made to order instead of stocked. HVAC units, switchgear, walk-in coolers, kitchen hoods, storefront glass, custom millwork. They get released for manufacture only after the scope is confirmed, so a two-week delay in choosing can turn into a much longer delay on site.
Who is responsible if the permit takes longer than expected?
Read your contract. On a lump-sum interior project, the contractor typically carries the construction duration, not the jurisdiction's review time — permit delay is usually an excusable extension of the schedule. That's normal, and it's why the schedule should show permitting as its own line rather than buried inside a total.
Does a smaller project get permitted faster?
Sometimes. Simple non-structural interior work with no change of use can qualify for a faster review track in some jurisdictions. Add a new kitchen, a new restroom, or a change of occupancy type, and you're in full review with more agencies involved. Scope drives the track, not square footage alone.
Get a real date, not a guess
If you have a space and a deadline, the next step is a site walk. We look at the space, ask what your operation actually needs, and build a schedule around the two things that matter — permitting and long-lead items — then price the work. Call (404) 724-8709. The call takes about 15 minutes: you describe the space and the date you're aiming at, we tell you what's realistic and what we'd need to see to confirm it, and we set the walk. Do it before you commit to an opening date, not after.
