How Long Does a Commercial Buildout Take?

Most owners I meet already have a date in their head. It is usually the date their current lease ends, or the date the landlord's free rent runs out. The building does not know that date. So the job is to work backward from it honestly.

How long does a commercial buildout take?

A commercial buildout, sometimes called a tenant improvement, typically moves through four phases: design and pricing, permitting, construction, and inspections with turnover. For a straightforward office of a few thousand square feet, construction itself often runs about eight to twelve weeks, but the full timeline from signed lease to move in is commonly four to eight months once design and permits are included. Restaurants, medical suites, and projects needing utility upgrades usually take longer.

The short version

  • Construction is usually the shortest phase, not the longest.

  • Design and permitting eat more calendar than most owners expect.

  • Long lead equipment can set your opening date before anyone swings a hammer.

  • Utility upgrades run on the utility company's schedule.

  • Bringing a contractor in early is the best way to protect a date.

Phase one: design and pricing

This is where the architect draws the space, the engineers design the systems, and the contractor prices it. For a simple office, this can move in a few weeks. For a restaurant or medical suite, it can take a few months, because the equipment has to be chosen before the systems can be designed.


This is also where the most time can be saved. Our post on what preconstruction is explains why.

Phase two: permits

Every township handles permits differently. In Philadelphia, applications go through the eCLIPSE portal at the Department of Licenses and Inspections. In the suburbs, each municipality has its own review process and its own calendar.


Complete drawings move faster. Incomplete drawings get comments back, and each round of comments adds time. Food businesses also need a health department plan review before construction starts, which we cover in What Permits Do I Need for a Restaurant Buildout?

Phase three: construction

Demolition, framing, rough mechanical, electrical, and plumbing, inspections, insulation, drywall, finishes, and final connections. Each step depends on the one before it. If you want to follow along, read How to Read a Construction Schedule Without a Hard Hat.

Phase four: inspections and turnover

Final inspections from the building department, fire marshal, and sometimes the health department. Then punch list, cleaning, and turnover. Plan a couple of weeks here, not a couple of days.

What quietly steals weeks

  • Long lead items. Electrical switchgear, rooftop HVAC units, storefront systems, and specialty equipment can take months to arrive. They need to be ordered early, sometimes before permits are issued.

  • Utility work. A new electrical service or gas meter is scheduled by the utility, not by your contractor.

  • Decisions. Every week spent choosing finishes or equipment is a week the schedule cannot use.

  • Landlord approvals. Most leases require the landlord to approve your drawings. Build that review time in.

  • Hidden conditions. Older buildings come with surprises behind the walls.

Frequently asked questions

How long does an office fit out take? For a few thousand square feet of standard office space, construction commonly takes eight to twelve weeks after permits are issued. Design and permitting add to that.


How long does it take to build out a restaurant? Longer than an office. Health department review, hood and fire suppression work, gas and electrical capacity, and equipment lead times all add time. Many restaurant projects take several months of construction alone.


Can construction start before permits are issued? Generally no. Some jurisdictions allow limited early work such as demolition under a separate permit. Always confirm with your contractor and the local building department.


What is the biggest cause of buildout delays? In our experience, late decisions and long lead equipment. Both are preventable with early planning.


How can I speed up my buildout? Bring your contractor in during design, finalize equipment early, order long lead items as soon as possible, and make decisions quickly.

Level Check

The fastest projects are not the ones where everybody works harder at the end. They are the ones where the hard decisions happen at the beginning. If you have a date that matters, tell your contractor on day one and build the plan backward from it.
