Myrtle Beach, SC?

Myrtle Beach full kitchen remodel permits — the key details

Myrtle Beach is a coastal municipality in Horry County, and the city building department enforces the 2018 IBC with South Carolina modifications. A full kitchen remodel — one that involves moving walls, relocating plumbing, adding circuits, or venting equipment to the exterior — triggers a 'Renovation' permit classification, which requires full architectural or engineer-stamped drawings. The IRC R302 requires a one-hour fire rating on kitchen walls that separate the kitchen from bedrooms or living areas; if you're removing or relocating a wall, the plan reviewer will verify that the remaining wall assembly meets this standard. The city's plan-review timeline is 3–6 weeks for a renovation-class kitchen permit, though expedited review (7–10 business days) is available for an additional $150–$300 fee if you submit a complete, code-compliant package on the first try. Expect to file a single Building Permit that pulls in three sub-permits automatically: Electrical, Plumbing, and Mechanical (if applicable). Many homeowners are surprised to learn that Myrtle Beach's online portal requires you to pre-select which trades you're touching before submission; if you understate your scope (e.g., you check 'no plumbing changes' but then move the sink), the permit is flagged for amendment and your timeline resets.

The 2018 IBC kitchen-specific rules are strict. IRC E3702 mandates two separate 20-amp small-appliance branch circuits in the kitchen, and they cannot serve any outlets outside the kitchen — a common rejection reason in Myrtle Beach plan review. IRC E3801 requires GFCI protection on every receptacle within 6 feet of a sink, including islands. Counter receptacles must be spaced no more than 48 inches apart (measured horizontally along the countertop), and the building department's checklists often catch submissions that space them 50 or 52 inches apart — a trivial fix but a plan-review delay. If you're adding a gas range or cooktop, IRC G2406 requires a dedicated gas shutoff valve within 6 feet of the appliance and labeled; if the gas line is being relocated (which triggers a Plumbing permit), the city will require a licensed plumber to sign off, and Myrtle Beach building inspectors will conduct a gas-tightness test (a $200–$400 third-party cost you inherit if the plumber doesn't pass it). Range-hood ventilation is where coastal Myrtle Beach differs sharply from inland South Carolina jurisdictions: because of salt spray and humidity, the city requires that any range hood ducting to the exterior terminate with a wall-mounted cap (not a roof-mounted termination, which is allowed inland); the duct must be rigid (not flexible) where it runs through exterior walls, and it must slope slightly downward to the exterior to prevent condensation backup. Missing the range-hood detail on your electrical plan is a near-guaranteed plan-review comment in Myrtle Beach.

Load-bearing wall removal requires an engineer's letter or a stamped beam-sizing design. The IRC R602.3 defines a load-bearing wall as any wall that carries roof or floor loads; in a single-story home, the wall running perpendicular to the roof trusses or the wall that the kitchen ceiling joists sit on is likely load-bearing. If you're removing a load-bearing wall in a kitchen open-to-living-room conversion, Myrtle Beach requires a Professional Engineer (PE) stamp on a design that shows the beam size, support points, and calculations. Many homeowners and even contractors try to submit a generic 'use a 2x12 LVL' note, which Myrtle Beach plan review rejects outright — the city wants the math. A proper engineering letter costs $400–$1,200, and it often extends your permit timeline by 2–3 weeks because the city's structural reviewer scrutinizes coastal wind-load and flood-zone implications (Myrtle Beach is a flood-zone A or AE area in many neighborhoods). If your home is in a flood zone, IRC R322 may require the kitchen-remodel design to account for flood elevation; if you're below the base flood elevation, FEMA rules prohibit certain finishes and mechanical systems in the kitchen area, and your permit will be flagged for flood-plain certification. This is a Myrtle Beach-specific gotcha that surprises inland homeowners.

Plumbing relocation is the second-most common rejection reason in Myrtle Beach kitchen permits. IRC P2722 governs kitchen-sink drain sizing and trap-arm geometry: the sink drain must be no smaller than 1.5 inches, the trap arm (the run from the trap to the stack) must be no smaller than the trap, and the arm cannot exceed 42 inches in length without a vent. If you're relocating the sink 8 feet or more from its current location, the plumber must reroute the supply lines (hot and cold) and the drain/vent, and the city will require a plumbing layout drawing showing the new routing, the vent-stack connection point, and the slope of the drain line (1/4 inch per foot, minimum). Coastal Myrtle Beach has additional plumbing quirks: water pressure in some neighborhoods (especially near the beach) is salt-heavy, and the city building department doesn't explicitly require soft-water systems, but the inspector may note if your chosen fixtures aren't rated for salt-water exposure — a comment that doesn't block the permit but can cost you $2,000–$5,000 in fixture upgrades down the line. The plumbing sub-permit alone costs $150–$400 depending on the scope, and plan review is 2–3 weeks.

The final practical step: file the Building Permit through the City of Myrtle Beach's online portal (or in person at City Hall, 3100 Mr. Joseph H. Harrelson Blvd), and the fee is typically $300–$1,500 depending on the estimated project cost — the city uses a formula of roughly 1.5–2% of the declared valuation. Once approved, you'll receive three separate permit cards (Building, Electrical, Plumbing) and a pre-inspection checklist. Schedule inspections with the building department's inspection line; each trade (framing, plumbing, electrical) has its own rough inspection, then drywall/insulation, then final. In Myrtle Beach, the final inspection includes a fire-barrier verification (the inspector will check that the wall between the kitchen and bedrooms has the required one-hour rating), an electrical final (all circuits tested and labeled), a plumbing final (water test under pressure, no leaks), and a mechanical final if applicable (range hood vent termination, gas shutoff valve, CO detector if gas is present). If your home was built before 1978, you must file a Lead-Based Paint Disclosure Affidavit with the permit; failure to do so will hold the permit in 'pending' status until you comply. Total timeline from filing to final sign-off: 6–10 weeks if the plan passes on the first review, 10–14 weeks if there are comments.

Three Myrtle Beach kitchen remodel (full) scenarios

Coastal Myrtle Beach: why kitchen-vent termination rules are stricter here than inland South Carolina

Myrtle Beach sits on the Atlantic coast, 3 miles from salt water. Homes in Myrtle Beach experience sustained salt-spray exposure, which corrodes metal faster than inland areas — aluminum ducts, steel caps, and copper gutters degrade 3–5 times faster here than in Columbia or Greenville. The city's building department has observed decades of failed kitchen vents: roof-mounted terminations where salt spray rusts the cap from the outside, flex ducts that collapse under salt-corroded weight, and flexible ductwork that harbors salt deposits and backs up into the kitchen. This experience drove Myrtle Beach's local amendment to the IBC: all range-hood ducts venting to the exterior MUST be rigid (no flex), MUST terminate in a wall-mounted cap (no roof), and the cap MUST face downward or sideways with a rain hood (no upward openings). This is NOT required inland; it's a Myrtle Beach-specific rule.

The rule also reflects humidity and condensation problems. Myrtle Beach's average relative humidity is 65–75% year-round. A poorly designed range hood duct — one that flexes, sags, or has upward-facing termination — collects condensation inside. Salt in the air deposits on duct interior walls, salt water condenses and pools in the duct sag, and within 2–3 years, the duct is clogged and breeding mold. The city's inspectors will not sign off a final permit unless the range-hood detail shows the rigid duct, the slope, the wall-mounted cap, and the inspector will physically climb a ladder to verify the cap is installed correctly. Plan-review comments flagging missing or incorrect range-hood termination details are the single most common kitchen-permit hold-up in Myrtle Beach.

Practical impact: if you're hiring a contractor who has only worked inland, they may not be familiar with this coastal rule. Insist that your electrician or HVAC technician confirms with the city building department that the range hood duct design meets Myrtle Beach's code — not state code, Myrtle Beach code. A mismatch adds 1–2 weeks to plan review and $300–$800 in ductwork rework.

Flood-zone kitchen remodels in Myrtle Beach: FEMA rules that override standard kitchen design

Myrtle Beach is split between flood-zone AE (high-risk) and flood-zone X (low-risk). If your home is in Zone AE, your kitchen must comply with FEMA flood-elevation rules, not just the IBC. FEMA's guidance (FEMA P-259, 'Hazard Mitigation Handbook') prohibits permanent kitchen cabinets, electrical panels, and HVAC equipment below the Base Flood Elevation (BFE) — the elevation that a 100-year storm surge is expected to reach. If your kitchen is below the BFE (many 1970s–1990s Myrtle Beach homes have first-floor kitchens in flood zones), you cannot install permanent cabinetry, built-in appliances, or electrical outlets below the BFE. You CAN install elevated or wet-floodproofed kitchens (elevated on posts, or kitchens with water-resistant finishes and mechanical systems relocated above the BFE), but this is expensive and unusual.

The city building department will require a Flood-Zone Certification (an affidavit signed by the homeowner or contractor stating that the kitchen design complies with FEMA rules) as part of the permit. If you're below the BFE and you ignore this, the permit will stall for weeks while the city's floodplain administrator reviews your submission. If you pull the permit without FEMA compliance and the inspector discovers the violation at framing inspection, the permit is revoked, the work is ordered stopped, and you may face fines. This is a Myrtle Beach-specific gotcha that affects roughly 30–40% of kitchens in flood-zone neighborhoods (especially older neighborhoods near the Intracoastal Waterway, like the areas around Barefoot Landing, Market Commons, or downtown Myrtle Beach).

To check your flood-zone status, visit the FEMA Flood Map Service Center (msc.fema.gov) and search your address; if you're in Zone AE, ask the city building department for the current BFE for your property. If your kitchen is below the BFE and you want to remodel, consult a licensed engineer or architect who specializes in coastal design — the cost of elevated or flood-proofed kitchen design adds $5,000–$15,000 to the project, but it makes the permit approvable and insurable.
