Charleston Build-Out Guide: What a Commercial Space Needs

Oct 21

Opening a gym, a therapy clinic, a restaurant, bar or bakery, a retail store or an office around Charleston? Once you and your commercial realtor have found a space where the rent and the location work, the next question is what it will take to make that space work for your business. The answers shape the budget, the permit path and the build-out plan, and they're easier to plan around when everyone on your team sees them early.

We're 3 Rivers Commercial Construction, a commercial general contractor based in North Charleston. Here's some of what our team and trade partners have built out and worked on around Charleston:

West Ashley: a physical therapy center on Sam Rittenberg Blvd, a children's developmental therapy center on Savage Rd, a 1920s house off Ashley River Rd converted into offices, and an MMA and jiu-jitsu training center off Savannah Hwy.
North Charleston: an MMA and jiu-jitsu training center off Rivers Ave.
James Island: a gym upfit and an entertainment facility we've worked on, both off Folly Rd.
Ladson: distribution center work off Ladson Rd, and a bakery build-out in progress (interior and exterior work).

We take on commercial work from the peninsula and Mount Pleasant to Summerville and Moncks Corner. These are the seven questions we'd ask about any space a business is considering.

1. Is the space approved for how you want to use it?

A retail suite becoming a restaurant, or a warehouse bay becoming a gym, is often a change of use. That may bring a different review by the building department and the fire marshal, and sometimes zoning. Ask your commercial realtor and your design professional early whether your use fits the space as it's permitted today.

2. Which permit office reviews this address?

Around Charleston, the parcel decides. A suite may sit in the City of Charleston, North Charleston, Mount Pleasant, Summerville, Moncks Corner, the Town of James Island or unincorporated county, and each office has its own process. Requirements vary by city and county, so knowing which one applies helps you plan the permit path. Our local pages for West Ashley, North Charleston, James Island and Ladson include notes on the local permit path.

3. What does the landlord deliver?

"Vanilla shell", "white box" and "as is" can mean different things in different leases. The work letter (or lease exhibit) usually spells out who pays for the HVAC, the restrooms, the storefront and the electrical service. Your commercial realtor and your attorney can help get anything vague put in writing. On the build-out side, bring the work letter, or the landlord's draft, to the walk-through, so the early planning range reflects the work your team expects you to cover.

4. How does the tenant improvement allowance fit the build-out?

An allowance can help, but how and when it's paid may matter as much as the amount. Some landlords reimburse after the work is done and lien waivers are in, so ask your commercial realtor how the payout works. On our side, a walk-through and a written early planning range show what the build-out could cost and how that compares with the allowance on offer. It's not a bid or quote.

5. What's above the ceiling and behind the walls?

In second-generation space, the biggest cost drivers are often the ones you can't see on a tour: the age and size of the rooftop unit, the electrical panel, where the plumbing lines run, and whether the fire sprinklers will need to move. What matters most depends on the business:

Gyms and training centers: restrooms and showers, flooring for mats, turf and weights, and HVAC for a big, busy open room.
Therapy and clinic suites: plumbing for treatment rooms and hand sinks, accessibility updates, and sound privacy between rooms.
Restaurants, bars and bakeries: the hood and exhaust, the grease interceptor, and the electrical and gas service for the equipment. A food business also needs a state food permit, and which agency issues it depends on the type of business.
Retail and offices: the storefront, restrooms, lighting and how the HVAC is zoned.

An early walk-through with your contractor is the time to look.

6. What's a realistic budget range for this space, and what's still unknown?

Before there are drawings, nobody can give you a firm price. What you can get is an early planning range: Low, Mid and High, with what's in, what's out and what's an allowance written down. It's not a bid or quote. It can help you and your commercial realtor judge whether the space fits your plans. The bid comes later, once there are drawings and the trade pricing is leveled.

7. Which parts of the build-out need the most lead time?

Permits, design and some equipment and materials can take longer than owners expect, and the order of the work depends on them. Your contractor can tell you which items usually need the most lead time on your type of space; nobody can promise a permit date. Your commercial realtor and attorney handle how the lease terms line up with that plan.

Your team for a build-out

Your commercial realtor, for the space search and the deal terms.
Your attorney, for the lease and the work letter.
Your design professional (architect or engineer), for what the space needs and what the building department and the fire marshal will require. If you don't have a design team yet, you'll hire and contract with your own architect and engineer directly.
Your commercial general contractor, for what the build-out could take and what's still unknown.
