Do I need a permit in Conway, South Carolina?
Conway's building permit system is handled by the City of Conway Building Department, which enforces the South Carolina Building Code (based on the 2015 International Building Code with state amendments). The department reviews residential projects ranging from small accessory structures to major renovations. Conway's coastal location and sandy soil create specific challenges — the 12-inch frost depth is shallow by national standards, and the mix of sandy soils near the Atlantic and clay-based soils inland means footing and drainage rules vary block by block. Owner-builders can pull permits for their own properties under South Carolina Code § 40-11-360, but most projects still require plan review and inspection. The city's permit process is straightforward for routine work: deck, fence, shed, addition, electrical, plumbing, HVAC. Plan review typically takes 2–3 weeks; simpler projects can sometimes be approved over-the-counter. Fees are calculated on project valuation, typically 1.5–2% of the estimated construction cost, with a $50–$150 minimum depending on project type.
What's specific to Conway permits
Conway sits in a 12-inch frost zone, which is shallow compared to inland South Carolina areas. This matters for any project involving footings or foundations. Deck posts, shed posts, fence posts, and utility structures must be set below the 12-inch frost line to avoid heave during winter moisture cycles. Most contractors bury posts 18–24 inches to be safe, but local soil conditions matter — sandy soils near the coast drain quickly and heave less; clay-based soils hold moisture longer and heave more. The Building Department will ask about soil type and sometimes require a soils report for additions or large accessory structures.
Coastal proximity brings additional rules. If your property is in a flood zone (most of Conway proper is), elevation certificates, flood-resistant materials, and wet/dry floodproofing strategies may be required for additions or substantial renovations. The city uses FEMA flood maps; confirm your flood zone before you file. Even outside mapped flood zones, drainage and stormwater management are scrutinized because the water table is high and sandy soils don't retain water. Decks and patios must not block natural drainage; sheds and additions must include grading plans showing water flow away from the house.
South Carolina adopted the 2015 International Building Code with state amendments. The state adds specific requirements for hurricane ties, roof fastening, and wind resistance — even though Conway is not in a high-wind zone like coastal Horry County. State amendments also address electrical work, plumbing, and HVAC in ways that differ from the base IBC. Expect inspectors to cite both the 2015 IBC and the SC Building Code amendments; they're sometimes stricter than the national model.
Owner-builders can pull residential permits for owner-occupied properties, but the city requires the owner to be the primary applicant and the property must be for personal use (not rental or flip). If you hire a contractor, they must hold a state license; if you're doing the work yourself, you can act as the owner-builder. Plan check and inspection requirements are the same regardless. The city does not waive any inspections for owner-built work.
Conway's permit portal status varies — the city may use an online portal or paper/in-person filing. Before you file, confirm the current method by calling the Building Department or checking the city's website. Most recent filings in Conway are processed in person at City Hall, though online portals have been introduced in some SC municipalities. Don't assume a digital process; plan for a phone call or visit.
Most common Conway permit projects
These are the projects that bring homeowners to Conway's Building Department most often. Each has specific thresholds, code sections, and local quirks. Click through to see what you'll need to file, what it costs, and what to expect.
Decks
Any deck over 30 inches above grade requires a permit in Conway. Posts must be set below the 12-inch frost line; coastal sand soils mean good drainage but shallow bearing capacity — footings may need wider pads. Deck stairs, railings, and flashing are inspected for rot and water damage risk.
Fence permits
Most residential fences under 6 feet in rear yards don't require a permit, but corner-lot and front-yard fences do. Pool barriers always require a permit, regardless of height. Setback rules are strict — fences can't cross easements or sight triangles. Sandy soils mean post holes must go deep to avoid leaning; inspectors often check concrete footings.
Shed and accessory structure permits
Sheds over 120–200 square feet typically require a permit (threshold varies by zoning). Posts and footings must be set below the 12-inch frost line. Drainage and grading plans are often required to keep stormwater away from neighboring properties. High water table in Conway means inspectors pay close attention to site conditions.
Addition and renovation permits
Any addition, room expansion, or major renovation requires permits for building, electrical, plumbing, and HVAC. Additions must meet setback and lot coverage rules. Flood-zone properties need elevation certificates. Energy code compliance (SC Code § 40-11-350) is required for alterations over 25% of wall area.
Electrical permits
Homeowners can do some electrical work (branch circuits, outlets, switches) without a license under SC owner-builder rules, but a permit is still required. Panel upgrades, service changes, and hardwired appliances may require a licensed electrician. Subpanel work typically requires a licensed electrician in Conway.
Roof replacement
Re-roofing (replacing shingles or materials on an existing roof structure) requires a permit in Conway. State and IBC rules on roof fastening, wind resistance, and tie-downs are checked. Inspections confirm proper flashing, underlayment, and ventilation — critical in a humid, moisture-rich coastal environment.

South Carolina context for Conway permits
South Carolina delegates building code administration to municipalities, but all jurisdictions must enforce the South Carolina Building Code, which is the 2015 International Building Code (IBC) with state amendments. The state code includes requirements for residential construction that supersede or supplement the IBC in areas like electrical work, plumbing, HVAC, and wind resistance. South Carolina Code § 40-11-360 allows owner-builders to pull residential permits for owner-occupied properties without a contractor's license, provided the owner is the primary applicant and the work is for personal use. However, certain trades (electrical service changes, plumbing vent systems, HVAC systems) may still require a licensed professional in Conway — check with the Building Department. South Carolina does not have a state-level permit portal; each municipality manages its own process. Conway follows the 2015 IBC with state amendments, which means code citations in permit documents will reference both the IBC section (e.g., IBC 2015 R301) and the SC Building Code section if there is a state difference. Flood insurance and FEMA compliance are critical in South Carolina's coastal municipalities; properties in mapped flood zones must meet elevation and floodproofing standards. Energy code compliance is enforced under SC Code § 40-11-350 for alterations over 25% of wall area, window area, or roof area.
Common questions
Do I need a permit for a small shed in Conway?
It depends on size and zoning. Most residential sheds under 120–200 square feet don't require a permit if they're in a rear yard and meet setback rules, but the threshold varies by zoning district. Anything over that, or any shed in a front yard or corner lot, requires a permit. Call the Building Department with your property address and proposed shed size to confirm. Even unpermitted sheds must have footings below the 12-inch frost line — sandy soils in Conway can heave in winter, and a sunken shed is expensive to fix.
What's the frost depth in Conway, and why does it matter?
Conway is in a 12-inch frost zone. Posts, footings, and pilings for decks, sheds, fences, and other structures must be set below 12 inches to avoid frost heave — the upward pressure that occurs when soil freezes and thaws. In sandy soils (common near the coast), heave is less severe but still occurs; in clay-rich areas inland, it's worse. Most contractors go 18–24 inches to be safe. Inspectors will ask about footing depth; don't estimate.
Can I pull a permit myself in Conway as an owner-builder?
Yes. South Carolina Code § 40-11-360 allows owner-builders to pull residential permits for owner-occupied properties. You don't need a contractor's license, but you must be the primary applicant and the property must be your primary residence (not a rental or investment). Plan review and inspections are the same as for contractor-built work. Some trades — like electrical service upgrades or plumbing vent work — may still require a licensed professional in Conway; confirm with the Building Department. You're responsible for code compliance and passing all inspections.
How long does a permit take in Conway?
Plan review typically takes 2–3 weeks for routine residential projects like decks, fences, and small additions. Over-the-counter permits (simple fence or shed applications) can sometimes be approved the same day. Once issued, the permit is usually valid for 6–12 months; check the permit itself. Inspection scheduling depends on the trade and season — electrical and plumbing inspections often happen within 1–2 weeks of notification. If the inspector finds issues, you'll get a correction notice and 10–30 days to fix and request re-inspection.
Do I need flood insurance or an elevation certificate in Conway?
If your property is in a FEMA-mapped flood zone (most of Conway proper is), yes. Check your flood zone on FEMA's Flood Map Service Center or ask the Building Department. If you're in a flood zone and adding to or substantially renovating your home, you'll need an elevation certificate (prepared by a surveyor) showing the finished floor elevation relative to the base flood elevation. Some additions and renovations in flood zones must be floodproofed — wet floodproofing (allowing water in utility areas) or dry floodproofing (sealing and elevating critical systems). This is required by the 2015 IBC and SC Building Code, and it's not optional in mapped zones.
What's the permit fee for a deck in Conway?
Permit fees in Conway are typically 1.5–2% of project valuation, with a minimum of $50–$150 depending on project type. A deck permit might run $75–$200 depending on the deck's estimated cost. When you file, you'll provide a project valuation (estimate of materials and labor); the city calculates the fee from that. Get a contractor estimate or materials list before filing so you can estimate accurately. Underestimating valuation can trigger a fee adjustment during plan review.
Who can do electrical work in Conway?
Under SC owner-builder rules, you can do branch-circuit work (adding outlets, switches, light fixtures) on your own home without a license, but you need a permit. Service upgrades, panel changes, hardwired appliance installation, and subpanel work typically require a licensed electrician. The Building Department will clarify which work qualifies as owner-builder work and which requires a licensed electrician. Always get the answer in writing or on a recorded call — electrical codes are strict, and non-compliant work can cause fires.
Do I need a site plan or survey for my permit?
For most residential projects, no — a simple sketch showing property lines, setbacks, and the structure location is enough. Larger additions, accessory structures in tricky locations, or properties in flood zones may require a more formal site plan. Surveys (prepared by a surveyor) are needed for elevation certificates in flood zones and sometimes for boundary questions. When you file, ask the Building Department what documentation they need for your specific project. Don't waste money on a full survey unless the department asks.
Ready to file your Conway permit?
Start by confirming your project type and property details with the City of Conway Building Department. Call or visit in person — a quick conversation will clarify whether you need a permit, what documentation to prepare, and what the fee will be. Have your property address, project description, and a rough budget ready. If you're still research-mode, pick your project type from the list above and read the detailed guide for that project. Most Conway permits are straightforward if you know the local rules upfront.
