How to vet a home contractor in South Carolina: field notes from the dispatch desk

Your roof starts shedding shingles after a coastal thunderstorm, the crawlspace smells like a Lowcountry marsh, and you need someone who can actually show up, pull the right permit, and leave the job clean. I spend a lot of my day talking to crews and homeowners around the state, from Horry County to the Upstate, and there’s a pattern to the jobs that go smooth. It starts with knowing exactly which license your contractor should hold here, what the permit will cost in your county, and how you protect yourself on payments and paperwork.

South Carolina runs on a couple of very specific systems: state licensing through Labor, Licensing and Regulation (LLR), local permitting through your city or county, and inspections tied to the 2021 South Carolina Building and Residential Codes implemented statewide on January 1, 2023. If you’ve been told “we don’t need a permit” for structural work or heavy mechanicals, assume the opposite and verify. The fees are usually smaller than the risk of a failed inspection when you’re already neck-deep in demo.

What license should my contractor hold for this job?

For typical houses, additions, decks, roofing, and interior remodels

For one- to two-family homes and townhomes not over three stories, most work falls under the Residential Builders Commission. A Residential Builder (RBB) can manage the whole job and all the trades. The current RBB license fee is $220 per cycle and the application processing fee runs $135. Residential Builders keep a $15,000 license bond on file at all times. That bond isn’t a substitute for insurance, but it is one more layer of accountability you can check.

Smaller, trade-specific work can be done by a Residential Specialty Contractor (RBS) registered in that trade. Registration for RBS is a straightforward process with a current $100 registration fee. If the job is $5,000 or more, a specialty registrant must post a $5,000 surety bond for that job class. If you’re hiring a painter for $3,500, that job-bond doesn’t apply; if you’re hiring a roofing crew for $12,000, it does.

For commercial spaces or very large projects

If your project is commercial or mixed-use, or you’ve got a cost number that clearly puts you in the commercial world, you’re looking at the Contractor’s Licensing Board. A General Contractor’s license is required for commercial construction of $10,000 or more. Licenses are issued in group limits. For perspective, Group 2 allows projects up to $400,000 and requires $60,000 net worth or a surety bond in the same amount; Group 3 goes up to $1,000,000 with $150,000 net worth or bond; Group 4 up to $3,000,000 with $250,000 net worth or bond; and Group 5 is unlimited with $350,000 net worth or bond. If your café build-out is $650,000, a Group 2 license is too small; Group 3 is the fit.

Want a quick license reality check? The Residential Builders Commission lists its phone as 803-896-4696 and shows its office at 110 Centerview Dr, Columbia. You can confirm an active license in minutes and ask whether the person you’re considering is a Builder or a Specialty registrant. It’s also normal for a contractor to show you their PSI exam pass letter and license card. For would-be licensees reading this, the PSI testing fee to sit for both Residential Builder exam portions is currently $90.

Who pulls the permit, and what will it cost where I live?

In South Carolina, your city or county sets permit fees. A homeowner can often pull their own single-family permit, but it changes what inspectors expect and who is responsible. In the City of Charleston, a homeowner can use the Non-Licensed Owner Intent to Build form for single-family residential work, with an exception that fuel-gas permits require a licensed contractor. Some jurisdictions also double the fee if you start without a permit, so the “let’s just get going” approach can get expensive fast.

Here’s how the numbers look in three places you might actually be pricing right now.

Greenville County uses a valuation-based schedule. As of the current sheet, there is a $36 minimum building permit for tiny scopes, and the county publishes standard valuations like $251.10 per square foot for heated residential space and $99.72 per square foot for unheated space. The fee table then steps by job value. Electrical permits have a $72 minimum, and there’s an $70 encroachment fee if your driveway or work ties into a county-maintained road. Greenville also announced a 20% increase to building permit fees effective July 1, 2025, so run your math with that in mind if your job is new or you’re re-submitting plans.

Horry County (Grand Strand and surrounds) prices new one- and two-family residential permits at $0.50 per square foot with a $50 minimum, plus a $25 zoning fee. Plan review is an upfront $0.20 per square foot. For commercial or multifamily, the rate structure is different, and R-2 occupancies run at a different per-square-foot number.

Charleston County separates zoning and building. A Residential Zoning Permit is $25, and the Building Inspection Services division follows the 2021 code with a local ordinance that allows the county to charge a double fee for work started without a permit. Charleston County has also consolidated several sub-trade permits under a single Main Building Permit, which can simplify tracking inspections and reduce repeated counter trips for separate electrical or mechanical sheets.

Real-world comparison for a new 2,000-square-foot single-family build:

• In Greenville County, the published valuation would be 2,000 x $251.10 = $502,200. Using the county’s permit-fee tiers, that yields about $2,500 in permit fees before the July 2025 20% increase. With the increase, budget roughly $3,000, plus trade permits and any encroachment fee.
• In Horry County, at $0.50 per square foot, the permit fee would be $1,000, plus $25 zoning and the $0.20 per square foot plan review ($400 for 2,000 square feet), for a total around $1,425 before any impact fees or utility-related charges.

None of this is meant to steer you to one county or another. The point is to show why a contractor who regularly works your jurisdiction will quote permitting accurately. Ask them to break out permit, plan review, and trade-permit lines on the estimate. If they get cagey when you ask for the building department’s fee reference, keep shopping.

How do I verify insurance and compliance without playing detective?

Licenses are half the story. Insurance is the other half. In South Carolina, most businesses that regularly employ four or more employees must carry workers’ compensation. Smaller one- and two-person outfits sometimes assume they can skip it; that’s how homeowners wind up on the hook for injuries. Ask for a Certificate of Insurance showing General Liability and Workers’ Compensation, issued to you as a certificate holder so you get notified if it cancels. If a contractor says they use only subcontractors, ask for sub COIs too. A license bond doesn’t cover injuries or damaged property.

On the licensing side, Residential Builders maintain a $15,000 bond on file with the Commission. Specialty registrants must provide a $5,000 bond for any $5,000+ job in their trade. On the commercial side, General Contractors either meet the group net-worth requirement or file a surety bond in the same amount. You can ask for the bond number and carrier and verify it’s in force. This isn’t nitpicking. It takes one odd gust on a windy roof day to turn a tidy job into a claim.

Finally, look at renewal timing. Residential Builder licenses run on a two-year cycle. The current renewal fee is $220, and the posted deadline for Builders, Home Inspectors, and COA licenses in the 2026 cycle was June 30, 2026. If a builder misses, the Commission’s reinstatement math stacks a $260 reinstatement fee on top of the renewal, bringing it to $480. If your project spans into summer, pick a contractor whose renewal isn’t hanging by a thread mid-job.

Payments, contracts, liens, and warranties that actually work here

Contract type matters more than the logo on the truck. For interior remodels, I like fixed-scope, fixed-price contracts with allowances clearly spelled out. For additions and structural changes, a cost-plus agreement can work if it includes written markup and a not-to-exceed number tied to permitted plans. Tie your draw schedule to inspections and visible milestones, and collect a signed lien waiver from the GC and major subs at each draw.

Make the permit and inspection plan part of the contract. In Lexington County, for instance, if your plans change and need re-review, the county lists a $115 residential plan or permit revision fee. If you burn inspections because the site wasn’t ready, some municipalities publish reinspection fees near $75 and step them up for repeated misses. Your contract should state who pays when schedule slippage forces extra trips.

On warranty, pin the basics to a date and a person. “We’ll take care of you” is not a plan. Ask for a one-year workmanship warranty in writing. For roofs and HVAC equipment, require the installer to register the manufacturer warranty to your address. If it’s a Builder doing the whole job, that’s fine. A Specialty registrant must not work outside their trade; a roofer can’t quietly take over an electrical sub’s scope just to keep the schedule moving.

Permit offices, hours, and practicalities: where the details trip people up

County processes aren’t identical, so two tips save grief all summer.

First, zoning is its own step even when it feels routine. Charleston County’s zoning side shows a $25 Residential Zoning Permit before you ever reach the building counter. In Horry County, zoning adds $25 to residential building permits as a standard line item. If your contractor has never submitted a site plan for setbacks, that’s your red flag.

Second, know when a homeowner permit makes sense. In Charleston, the Non-Licensed Owner Intent to Build pathway is real, but the city excludes fuel-gas from homeowner permits and expects you to act as the responsible party for code compliance. In practice, that means you coordinate trades and inspections and take the calls if something fails. On a full kitchen gut, let the Builder pull the main building permit and the electrical, mechanical, and plumbing trades pull theirs under that umbrella.

Inspections run on the 2021 codes. In wet coastal soils, inspectors pay extra attention to footings, uplift connections, flood elevations, and fastener specs. In the Upstate, everybody has a story about a July afternoon storm that swamps an open trench. Ask your contractor who tarps, who pumps, and when they call in the trench inspection. A crew that has those answers also tends to show up with the right nails for the coastal wind zone and the right termite shield at the sill.

Quick takeaways you can act on today

• Match license to scope. For whole-house and structural work, hire an RBB; for trade-only scopes under $5,000, an RBS in that trade is fine. Commercial work over $10,000 needs a General Contractor with the right group limit.
• Verify the money lines. Residential Builder fee is $220 to renew, application processing $135, and the Builder’s $15,000 bond must be on file. Specialty registrants pay $100 to register and must carry a $5,000 job bond on $5,000+ scopes.
• Price permits where you live. Greenville County uses valuation with a $36 minimum and a published 20% increase starting July 1, 2025; Horry County is $0.50 per square foot plus $25 zoning and $0.20 per square foot plan review. Charleston County’s zoning starts at $25 and doubles building fees for unpermitted starts.
• Ask for COIs. If there are four or more employees, workers’ comp is required. Get General Liability and Workers’ Comp certificates naming you as certificate holder.
• Make the permit plan part of the contract. Tie draws to inspections and require lien waivers. Budget reinspection or revision fees where your county publishes them, such as $115 for Lexington County residential plan revisions.
• Don’t ignore timing. Residential Builder renewals hit on June 30, 2026 this cycle. A lapse costs $480 to reinstate, so hire someone current if your job spans the summer.

Reader Q&A

How can I tell if my roofer’s “license” is enough for a $12,000 job?

Ask whether they’re a Residential Builder (RBB) or a Residential Specialty Contractor (RBS) registered for roofing. Either works at that size, but if they’re an RBS doing a roof over $5,000, they must have a $5,000 bond for that scope on file. A Builder maintains a $15,000 license bond at all times. Verify through LLR and ask for a current Certificate of Insurance.

My contractor says I should pull the permit to save time. Is that smart?

Not usually for anything beyond very small projects. In Charleston, a homeowner permit is allowed for single-family work except fuel-gas, but you become responsible for coordinating inspections and compliance. In Greenville and Horry, permit fees are predictable ($36 minimum in Greenville for small scopes, $0.50 per square foot plus $25 zoning in Horry), and a contractor who knows the counter saves you rejected submittals. Make the contractor pull it and own it in the contract.

What should a typical payment schedule look like in South Carolina?

Keep it simple: a modest deposit, then draws tied to inspections and milestones, with lien waivers each time. If your county charges for plan revisions or reinspections (Lexington lists $115 for a residential plan or permit revision), spell out who pays if scope changes or missed inspections cause extra trips. Always confirm the contractor’s license and bond status before the first check.

Do permit fees really vary that much by county?

Yes. A 2,000-square-foot new home in Greenville, using the county’s valuation of $251.10 per square foot, will see a building permit around $2,500 before the 20% increase, plus trades. The same home in Horry is $0.50 per square foot plus plan review and a $25 zoning fee, totaling roughly $1,425. That’s why local experience matters when a contractor quotes permits.

At this point, narrow your list to two contractors whose license actually fits the job and who can explain your county’s permit math without a shrug. Call the one who sent a clean estimate with line items for permits, inspections, and a lien-waiver schedule, then book the second as your backup if timing slips.
