BALDWIN BUILDERS

Charleston County General Contractor

Built Strong

Charleston County is six different building departments, three flood-zone regimes, and one historic district overlay. Baldwin Builders runs the full county under one SC general contractor license — peninsula, Mount Pleasant, James Island, West Ashley, Johns Island, and the sea islands — coordinating permits, inspections, and trades through every jurisdiction without handing you off to a local sub.

Cities & Communities

Where We Build in Charleston County

Each municipality in the county has its own permitting authority and flood-zone profile. Pick yours for locality-specific notes — historic district considerations, FEMA elevation, and the trade base we use there.

Building & Renovating in Charleston County

Charleston County runs from the historic peninsula across the Cooper and Ashley rivers to the sea islands — a different permitting authority, flood profile, and architectural tradition in nearly every municipality. We build the full county under one SC general contractor license, and the detail that drives cost, foundation, permitting, and timeline is below.

How does permitting work across Charleston County?

Charleston County properties fall under many permitting authorities depending on address — the City of Charleston, Mount Pleasant, North Charleston, Folly Beach, Isle of Palms, Sullivan's Island, and unincorporated Charleston County each issue and inspect separately. Projects in designated review areas also require Board of Architectural Review (BAR) approval. We confirm the governing authority for your specific lot and manage the appropriate path from scope through final inspection. See our Charleston and Mount Pleasant pages for municipal detail.

How much does a custom home cost to build in Charleston County?

Costs range widely across the county. Mainland builds in Mount Pleasant and West Ashley typically run $250 to $375 per square foot, while sea-island builds with elevated piling foundations and premium finishes commonly run $400 to $650 per square foot, and historic-district builds with BAR coordination can exceed $700. See our area pages for locality detail, or our full custom home cost guide.

What foundation types do the county's flood zones require?

Foundation type depends on lot location and FEMA flood zone. Mainland sites in Mount Pleasant and West Ashley commonly use slab-on-grade or stem-wall foundations with structural fill. Sea-island and V/VE-zone lots on Sullivan's Island, Isle of Palms, James Island, and Folly Beach typically require deep timber, concrete, or composite pilings driven below scour depth and elevated above the Base Flood Elevation. See our FEMA flood zones guide.

Do historic-district rules apply to new builds and renovations?

If your lot falls within the City of Charleston's Historic District, Old and Historic District, or Old City Height District, designs must be reviewed and approved by the Board of Architectural Review (BAR) before permits issue — the BAR evaluates massing, materials, fenestration, and roof form for compatibility with the surrounding fabric. We coordinate the review path with your architect from concept stage forward.

What kinds of projects do you take on countywide?

From peninsula single-house renovations to new custom homes on the sea islands, we handle new construction, additions, whole-home remodels, and standalone kitchen and bathroom work across the county — all on a cost-plus fixed-fee model with a single project manager coordinating permits, trades, and inspections across jurisdictions.

Customer Reviews

Dan Renne

Myrtle Beach • Bathroom remodeling • 5.0

★★★★★

"We recently had our bathroom completely remodeled by Baldwin Builders, and they did an absolutely amazing job! From the initial consultation to the final walkthrough, the entire team was professional, communicative, and attentive to every detail. They stayed on schedule, kept the worksite clean every day, and minimized disruptions to our home. We couldn’t be happier with the results and highly recommend Baldwin Builders!!"

Tina Gibbins

Cherry Grove Beach • Condo Renovation • 5.0

★★★★★

"We were referred to Baldwin Builders by a friend and are so pleased. Our newly purchased vacation condo needed to be completely painted, bedroom flooring replaced to match existing, a new kitchen fixture and desk area built. The tricky part was coordinating this while living 3 states away. George walked the property, gave great suggestions and had a proposal to us in a few days. There was a lot of coordination needed to gather materials but he didn’t miss a beat and took it all in stride. His communication with calls and photos and his responsiveness was fantastic. They matched the existing flooring perfectly and made my workspace vision come to fruition. If you want quality work done, call Baldwin Builders. You won’t be disappointed."

Bill Baker

SC • HVAC Renovation • 5.0

★★★★★

"We recently purchased an older home in SC knowing some work would be required before leaving our home state. We turned to our many long-term acquaintances in the area for contractor recommendations. Repeatedly, Baldwin Builders came up on the top of every list. We engaged them to oversee our major HVAC renovation project after they provided the most competitive price of all bids. Baldwin Builders was sensitive to our absence during the project and contacted us almost daily with project status and solutions to any unforeseen challenges. Just before our return to SC, we were notified they completed the final inspection of the project and the subcontractor was returning that day to rectify one minor punch item. I would characterize Baldwin Builders as a company of uncompromising integrity and pro-active communicators who provide professional oversight of projects. We will use them for ALL our planned project here in SC!"

"Baldwin Builders recently remodeled our bathrooms, and we couldn’t be happier with the outcome. From the initial consultation to the final walkthrough, their team was professional, responsive, and detail-oriented. They helped us choose modern fixtures, updated the flooring, and improved the overall layout to make the space more functional. The crew was punctual, kept the work area tidy, and made sure to minimize any disruption to our daily routine. The transformation is incredible—our bathrooms now feel like a high-end spa. Highly recommend Baldwin Builders for any remodeling needs!"

Myrtle Beach • Bathroom Remodel • 5.0

★★★★★

"I have nothing but great things to say about Baldwin Builders. I had a guest bathroom remodel done by them and it turned out amazing. They paid attention to detail, cleanliness and finished the job within a short/appropriate amount of time. I would definitely recommend this young, professional, up-incoming business to anyone for home repair/updating needs."

Thomas Veith

North Myrtle Beach • Full Home Remodel • 5.0

★★★★★

"I hired Baldwin Builders to do a full renovation on my beach vacation rental and have nothing but great things to say about them. At first I was hesitant to hire a younger team, but their experience and dedication has been proven through the quality of their work. Their head sales guy, George, was with me through the entire project displaying perfect communication and was someone I could count on answering the phone anytime I had a question. He went above and beyond to hold everyone accountable and shared my vision as if it was his own. One last thing I thought was special was Larson, the owner, delivered my estimate and acted in my best interest throughout the entire project displaying honesty and transparency. Nice to see a young squad so eager and determined to leave an impact and I will definitely be calling them for my next build!"

Thomas Neat

North Myrtle Beach • Home Addition • 5.0

★★★★★

"I don’t know where to begin explaining how happy I am with my sunroom. It was a screened porch and I said I wanted a room to use all year round with a view of the pond behind me. Beyond my expectations. George, Larson, and crew worked fast, kept me up to date, treated my family and even my pets with respect. I will not hesitate to call them if I have another project."

Andrew Zaloom

North Myrtle Beach • Full Home Remodel • 5.0

★★★★★

"I could not be happier with the quality and service that both Larson and George provided. From the initial consultation to delivery, they were thorough, honest, and attentive. Within a few days, they were able to do an extensive door replacement and structural repair. I own several rental properties in the area and this was the first group I’ve worked with that did not over promise and under deliver. I could not recommend them enough. Thank you Larson, George, and Baldwin Builders. "

Little River • Bathroom Remodel • 5.0

★★★★★

"After building a new house and being left without shower doors for our walk in luxury tile shower it was a major burden . We researched and looked for a couple of weeks to find a builder to install shower doors and Baldwin Builders came in showed us our options for our price range and was prompt in delivering what we decided on . Larson is extremely efficient and knowledgeable. The installation was easy and perfection. We will be calling Baldwin Builders from now throughout the future for all of our projects no matter how big or small they are our "go to". If you are looking for a contractor who cares and is professional , Baldwin Builders is your company ."

"Hired Baldwin Builders last minute to build a staircase for my porch. We needed it done quickly. I gave them pictures on a Friday and it was DONE Monday!! AND it was absolutely perfect; exactly what we wanted and hundreds less than the other 2 companies we called. Ask for George or Larson: both were great!!"
