What happens if you skip the permit (and you needed one)
- Stop-work orders carry a $100–$500 fine in Simpsonville, and the city can order removal of unpermitted work at your cost — potentially $2,000–$10,000 if cabinets, electrical, or plumbing must be torn out.
- Your homeowner's insurance will deny claims on unpermitted work; if there's a kitchen fire or electrical fault, you're uninsured and liable for the full loss.
- When you sell, South Carolina's Property Owners' Association (SCPOA) disclosure law requires you to disclose unpermitted work — title companies flag it, lenders won't finance until it's permitted and inspected, and buyers demand credits.
- Electrical or plumbing unpermitted in a kitchen almost always surfaces during a home inspection; buyers walk or demand $5,000–$15,000 credits, killing your deal.
Simpsonville kitchen remodel permits — the key details
The City of Simpsonville Building Department requires a permit whenever you move, remove, or alter any of the following in a kitchen: load-bearing or non-load-bearing walls, plumbing fixtures (sink, dishwasher, water lines), electrical circuits, gas appliance connections, range-hood exhaust ducting through an exterior wall, or window/door openings. The rule is rooted in IRC R301.2 (structural integrity) and IRC E3702 (kitchen circuits), both adopted by the city. A cosmetic-only kitchen — new cabinets in the same spot, countertop replacement, appliance swap on existing circuits, paint, flooring — does NOT require a permit. But the moment you relocate a sink by more than a few feet, add a second dishwasher, or cut into a wall for a range-hood duct, you cross the threshold. The city's definition of 'relocation' is practical: if the rough-in (plumbing or electrical lines) must move, you need a permit. If only the finish cabinet moves, you don't. Simpsonville's Building Department is smaller and less automated than Greenville or Charleston, so expect a phone call or in-person visit to clarify what you're planning before you file.
Simpsonville requires three separate permits: building, electrical, and plumbing. This is critical and often missed. Many homeowners think one permit covers everything; it doesn't. The building permit covers framing, load-bearing wall removal (with engineer's letter), and the overall scope. The electrical permit covers all new circuits, GFCI outlets, range-hood wiring, and any gas-appliance ignition circuits. The plumbing permit covers sink relocation, drain-vent routing, dishwasher rough-in, and garbage-disposal lines. If you're adding a range hood with exterior ducting (very common), you'll also need a mechanical/ventilation review under your electrical or building permit — the city will tell you which during intake. Permit fees are typically 1.5–2% of the declared project valuation. For a $25,000 kitchen (typical mid-range remodel), expect $300–$500 total permit fees across all three. For a $50,000+ kitchen, $750–$1,500. The city requires detailed plans: electrical load calculation, plumbing trap-arm and vent routing, kitchen-counter receptacle spacing (max 48 inches apart per NEC 210.52(C)(1)), and GFCI protection on all counter outlets and the sink. If you're removing a load-bearing wall, you must submit a structural engineer's letter and beam-sizing detail — this triggers plan review and adds 1–2 weeks. Non-load-bearing walls are faster.
South Carolina's plumbing code (adopted by Simpsonville) requires kitchen sinks to have a minimum 3-inch drain with a 3-inch trap and a 1.5-inch vent arm within 2.5 feet of the trap weir per IRC P2704. If you're relocating the sink away from the existing stack, the city wants to see the vent routing on the plan — a common rejection is 'drain and vent detail not shown.' Dishwashers must have an air gap or backflow preventer; many kitchens in Simpsonville's piedmont zone sit on clay or mixed soils, so drainage is slow, and the city enforces this strictly. If you're adding multiple plumbing fixtures (sink + dishwasher + water-line relocation for a new fridge), the city may require a separate plumbing narrative explaining how the drain stack capacity is maintained. For electrical, Simpsonville enforces the 2020 National Electrical Code (NEC), adopted with SC amendments. This means GFCI on all kitchen counter outlets (not just within 6 feet of the sink anymore — the 2020 edition extends this), GFCI on all islands and peninsulas, and two dedicated small-appliance branch circuits (20-amp minimum) for counter outlets per NEC 210.52(C)(1). A very common rejection: the plan shows only ONE small-appliance circuit covering the whole counter. The city will email back: 'Two 20-amp circuits required for kitchen counters.' Know this before you file. If you're relocating a gas range or adding a gas cooktop, you need a licensed gas fitter's permit and inspection; Simpsonville requires this as a sub-permit under the building permit.
Simpsonville's piedmont location (near Greenville) has seasonal humidity and occasional freeze-thaw. This affects your kitchen's exhaust ventilation and sink-freezing risk on exterior walls. If your range hood or sink is on an exterior wall, the city's plan review will flag it: 'Duct termination detail required' and 'Insulation and drip-cap detail for exterior wall penetration.' Simpsonville requires an R-value specification for ducts running through unconditioned attic space (typically R-8 minimum) and a manual damper or gravity-damper cap at the exterior to prevent cold-air backflow. If you're moving the sink to an exterior wall, the city may require a sink-cabinet drain-heat-trace detail if the local inspector is thorough — this is not universal, but piedmont clay-soil Simpsonville homes sometimes have this in their local amendments. Call the Building Department before filing if your sink or range hood is near an exterior wall; they'll tell you what they want on the plan. Also, Simpsonville's online permit portal is minimal; you will likely submit plans on paper to City Hall or via email. There is no portal tracking like Charleston or Columbia offers. This means you must follow up in person or by phone to check on plan-review status. Budget an extra week for mailed-in turnaround if you're not submitting in person.
The inspection sequence for a Simpsonville kitchen remodel is: rough plumbing (before drywall), rough electrical (after framing, before drywall), framing (if walls are moved), drywall/insulation (after utilities are rough-in approved), and final inspection (fixtures installed, all trim and paint complete). If you have a load-bearing wall removal, the framing inspection is critical; the city inspector will verify beam sizing, bearing length, and load-path before sign-off. Budget 1–2 weeks between each inspection for contractor scheduling and city availability. The city's inspection team is shared with County services, so response times can stretch to 3–5 business days. If you're an owner-builder (allowed under SC Code § 40-11-360), you can pull the permits yourself, but you must be the one performing the work — not hiring a general contractor. If you hire licensed subs (electrician, plumber, framing crew), you must list them on the permit application. The city will cross-check their licenses; unlicensed work is a rejection and fine. Total timeline: 3–6 weeks for plan review (longer if rejections), plus 4–8 weeks for construction inspections and corrections. Do not start work until you have a signed permit in hand.
Three Simpsonville kitchen remodel (full) scenarios
Plumbing challenges in Simpsonville's piedmont kitchen remodels
Simpsonville's soil is piedmont clay overlaid with sand in some areas and red clay in others — this affects drainage and trench depth for kitchen remodels. If you're relocating a sink more than a few feet, the new drain line may need to tie into an existing stack that's 15–20 feet away. The city requires the plumbing rough-in plan to show the trap arm (the horizontal section of pipe before the vent) and the vent routing. IRC P2704 limits trap-arm length to 2.5 feet; longer runs require a calculation and often a larger-diameter vent line (2-inch instead of 1.5-inch). Simpsonville's plan reviewers are thorough on this because clay soils don't drain as fast as sandy soils, and improper venting leads to slow drains and sewer-gas backups.
If your kitchen sink is on an exterior wall, the city may require insulation and a drip-cap detail because piedmont freeze-thaw cycles can freeze exposed pipes in winter. Cabinets on exterior walls must be insulated behind the sink, and any water-supply lines must be wrapped or heat-traced. The plumbing inspector will look for this during rough-in. Also, if your house has a septic system (common in rural Simpsonville), the plumbing permit will flag this — septic systems have stricter drain-waste rules, and the city will cross-reference septic design documents. Garbage disposals, in particular, are often restricted or require special grease traps in septic systems. Call the Building Department before you file if you have septic; they'll tell you what the septic permit requires.
Dishwasher installations trigger a secondary rule: air-gap or backflow preventer. If you're adding a new dishwasher, the drain line must have an air gap (small cylinder that sits on the counter or under the sink) to prevent contaminated water from flowing back into the dishwasher. Many homeowners skip this to 'keep the counter clean,' but Simpsonville's city inspector will flag it as a code violation during final. Budget $50–$150 for an air gap and installation. If your house has high groundwater or is in a flood-prone area (check the FEMA flood map), the plumbing inspector may require a floor drain or sump pump near the kitchen to prevent backups — this is additional cost and scope.
Electrical circuits and GFCI in Simpsonville's 2020 NEC adoption
Simpsonville adopted the 2020 National Electrical Code with South Carolina amendments, which expanded GFCI protection. In older kitchens, GFCI outlets were only required within 6 feet of a sink. In 2020, the code expanded this to ALL kitchen countertop outlets, including islands and peninsulas. This means every outlet on every kitchen counter must be GFCI-protected or on a GFCI-protected circuit. If you're doing a full remodel and replacing outlets, plan for this. The city's electrical plan reviewer will count every outlet on your plan and verify GFCI protection. A common rejection: 'Outlet at east counter near refrigerator is not GFCI-protected.' The fix is simple (install a GFCI outlet or use a GFCI breaker), but it delays permitting.
The two small-appliance branch circuits rule is non-negotiable in Simpsonville. NEC 210.52(C)(1) requires at least two 20-amp circuits dedicated to kitchen counter outlets. These circuits must NOT be shared with appliances like the garbage disposal or dishwasher. Many homeowners' existing kitchens have only one circuit covering the whole counter; when you remodel and add outlets, you MUST split them across two circuits. If your electrical panel is at capacity, you may need to add a sub-panel — this is expensive (often $1,500–$3,000) but required if there's no room for two new 20-amp breakers. The city's plan will show your load calculation; the electrician must verify that your service panel (typically 100-amp or 200-amp residential) can support the load. If you're in an older Simpsonville home with a 60-amp service, you may need a service upgrade — the inspector will catch this at rough-in.
Gas range ignition and island outlets require careful planning. A new gas cooktop or range needs a 240V circuit for the ignitor and safety controls (even though it cooks with gas). This is a dedicated 20-amp circuit, separate from the two small-appliance circuits. Island outlets also need their own 20-amp circuit (not shared with counter outlets). If you're adding an island with four outlets, that's a dedicated 20-amp circuit just for the island. For a mid-size kitchen remodel with a gas range, an island, and two perimeter counter circuits, you're looking at FOUR new 20-amp circuits minimum. Verify your panel has room; if not, budget for a sub-panel or service upgrade. The electrical permit will show this load calculation upfront, so plan accordingly.

Common questions
Can I do a kitchen remodel myself without a contractor in Simpsonville?
Yes, under South Carolina Code § 40-11-360, owner-builders can pull permits and perform their own work. However, you must be the one physically doing the work — you cannot hire a general contractor. You CAN hire licensed sub-trades (electrician, plumber, gas fitter) for specialized work; they'll be listed on the permit. If any work is performed by someone you hire without a license, the city will reject the permit or order removal. Call the Simpsonville Building Department to confirm your scope is owner-builder eligible; structural work (wall removal) typically requires a contractor or engineer sign-off.
What if my house was built before 1978 and has lead paint?
Federal law requires lead-paint disclosure on any project involving a pre-1978 home. The Simpsonville Building Department will flag this when you pull the permit and provide you with an EPA disclosure form. You must acknowledge awareness of potential lead hazards. If your remodel disturbs paint (which it will if you're removing drywall or cabinets), you may be required to hire a lead-safe work practitioner — cost is typically $500–$1,500 for containment and cleanup. The city may not enforce this strictly for owner-occupied remodels, but it's required by federal law. Ask the Building Department when you file.
How long does plan review take in Simpsonville?
Plan review typically takes 3–4 weeks for a mid-size kitchen remodel (two permits) and 4–6 weeks for a full scope (four permits). This assumes no rejections. If the plan reviewer finds issues (missing vent details, GFCI not shown, load-bearing wall without engineer letter), you'll get an email or phone call listing corrections. You then resubmit, and review restarts — add 1–2 weeks per rejection cycle. Simpsonville's permit office is smaller than Greenville, so turnaround is slower. Submit plans early and call to check status weekly; don't wait passively.
Do I need a structural engineer's letter if I'm removing a kitchen wall?
If the wall is clearly non-load-bearing (e.g., a short wall between two rooms with no header above it, no joists bearing on it), the framing inspector may approve it without a letter. If there's ANY uncertainty, you MUST hire a structural engineer ($300–$800) to review the wall and provide a letter confirming it's non-load-bearing or sizing a replacement beam. Simpsonville's building code (IRC R602) requires this for walls within 8 feet of main support beams or if the wall runs perpendicular to joists. When in doubt, get the letter upfront; it's cheaper than delaying permit review by a month.
What happens during the electrical rough-in inspection?
The electrician installs all wire, boxes, and circuit pathways but not outlets or fixtures. The inspector checks that wire is correct gauge for the circuit amperage, boxes are properly secured, GFCI outlets are installed at the right locations, and all work complies with the NEC. For a kitchen, the inspector will count outlets, verify two small-appliance circuits, confirm island or peninsula outlets are GFCI-protected, and check the gas range 240V circuit and range-hood circuit. If anything is wrong, the inspector will mark it as 'conditional pass' or 'fail,' and the electrician must correct it before drywall closes it in. Budget 3–5 business days between rough-in request and inspection date; the city is shared with county services and can be slow.
Can I start work before the permit is officially approved?
No. In South Carolina, you cannot legally begin work until you have a signed, approved permit in hand. Starting before permit approval is a violation and can result in stop-work orders, fines ($100–$500), and orders to remove unpermitted work at your cost. Even if you have a receipt for a submitted permit, that is not approval. Wait for the city to issue the signed permit — it will have a permit number and the building official's signature. Only then do you call for inspections and start work.
What if the city inspector fails my work during rough-in?
The contractor must correct the issue and call for re-inspection. Re-inspections are typically scheduled within 3–5 business days. Minor issues (a couple of outlets not GFCI, one box not secured) usually pass on re-inspection. If the issue is major (e.g., wrong wire gauge, missing vent line, improper trap arm), the contractor may need to tear out work and redo it — budget extra cost and timeline. The permit remains open until all inspections pass and final approval is issued. Do not close walls or install fixtures until the city approves rough-in.
What is the typical cost of a full kitchen remodel permit in Simpsonville?
Permit fees are calculated as a percentage of the declared project valuation, typically 1.5–2%. For a $25,000 kitchen remodel, expect $300–$500 in permit fees across all three sub-permits. For a $50,000 remodel, $750–$1,500. The city will ask you to declare the project cost on the permit application; under-declaring can trigger an audit or correction. It's better to estimate high and adjust if the inspector questions it. Fees are nonrefundable once the permit is issued, even if you cancel the project.
Do I need separate permits for cabinet, countertop, flooring, and backsplash, or is it one permit?
One building permit covers the whole kitchen remodel scope, including cabinets, countertops, flooring, and backsplash. However, if you're also doing electrical, plumbing, or gas work, you pull separate electrical, plumbing, and (if applicable) mechanical permits under the same project. So typically: one building permit + one electrical permit + one plumbing permit = three permits for a typical kitchen remodel. The building permit covers the non-trade-specific work (flooring, cabinets, structure); the electrical and plumbing permits cover their respective systems.
What if I'm relocating the sink to an exterior wall in a Simpsonville piedmont home?
Exterior-wall sink relocations require special attention in Simpsonville's climate because of freeze-thaw cycles. The plumbing plan must show insulation behind the sink cabinet, and water-supply lines must be protected (wrapped insulation or heat trace) to prevent freezing in winter. The city's plan reviewer will ask for an insulation R-value spec and a detail showing the drain drip-cap. The plumbing inspector will verify this during rough-in. If you don't insulate properly, pipes can freeze and burst — a costly fix in spring. Budget for proper insulation and materials ($200–$400) as part of the project.
