What happens if you skip the permit (and you needed one)
- Stop-work orders and citation fines: Greer code enforcement can issue a stop-work order and fine $250–$500 per day of unpermitted work; the city may also place a hold on future permits.
- Forced removal or expensive retrofit: If an inspector finds unpermitted roof-to-wall straps or secondary membrane during a later inspection (roof repair, selling the home), the city can require removal and re-do under permit — costing 30–50% more than the original job.
- Insurance denial: Homeowner's policies often exclude damage from unpermitted structural work; a catastrophic wind event could leave you uninsured if retrofits were not permitted and inspected.
- Resale disclosure and lien risk: South Carolina requires sellers to disclose unpermitted work; title issues and lender refusal can delay or kill a sale, and the city can place a construction lien.
Greer, SC hurricane retrofit permits — the key details
Greer adopted the South Carolina Building Code, which is the 2018 International Building Code with state-specific amendments. For hurricane/wind retrofit, the critical section is IBC R301.2, which requires roof-to-wall connections to resist uplift and lateral loads. Your design wind speed in Spartanburg County is approximately 90 mph (3-second gust), per ASCE 7 and USGS hazard maps — lower than coastal areas but still significant. Any work that upgrades those connections — roof-deck attachment, hurricane straps, secondary water barriers (peel-and-stick membrane nailed or adhered under shingles), impact-rated windows, or garage-door bracing — requires a permit and plan review. The South Carolina Residential Builders Commission (SCRBC) oversees contractor licensing; homeowners can do their own work under SC Code § 40-11-360, but must pull the permit themselves and pass city inspection. Unlike Florida's MyHome grant program (which offers up to $10,000 for retrofits), South Carolina does not have a statewide retrofit subsidy — but some home insurance companies (State Farm, SCPIE, Federated) offer 5–15% premium discounts post-retrofit if you provide proof of engineering and inspection. Those discounts typically recover your retrofit cost in 3–5 years. You do NOT need a Miami-Dade TAS 201 shutter label in Greer; instead, your engineer specifies fastener pull-out resistance in pounds-force, per the test reports from the shutter manufacturer. Greer's building department is in-person and online; you can download the permit application from the city website or submit via their portal if available (verify current URL with the department directly).
The permit process in Greer is straightforward but thorough. You submit a completed permit application (with photos and scope description), a one-page engineer's letter or a full set of construction drawings (scaled plans showing roof-to-wall strap locations, window model numbers, garage-door reinforcement details, and secondary water-barrier locations), proof of contractor license (if you're hiring out), and a check for permit fees. Over-the-counter review is possible if your scope is small (e.g., hurricane shutters only, or one window upgrade); larger retrofits (whole-roof strap system, multiple windows, secondary barrier, garage-door bracing combined) typically go to full plan review, which takes 5–10 business days. Once approved, you're issued a permit card. Work is done under that permit, inspected in progress (before drywall/siding closes up the fasteners) and at final. For roof-to-wall straps and secondary water barrier, the city wants to see nails or screws installed per the engineer's drawing — typically 6 to 8 feet on center along rafters/trusses. For impact windows, the inspector verifies the model numbers match the approved plans and checks installation details (sealant, fastener spacing). Garage-door bracing is inspected for proper bracing-kit installation per manufacturer and design specs. The final inspection sign-off is your proof of permitted and inspected work — essential if you later sell or file an insurance claim. Permit fees in Greer typically run $200–$600 depending on total scope valuation; a partial retrofit (shutters + some windows) might be $250–$350, while a whole-house package (all windows, roof straps, secondary barrier, garage-door bracing) could hit $500–$600. The fee is usually a flat amount per permit, not a percentage of project cost. Greer does not charge re-inspection fees if your work fails initial inspection and you correct it — re-inspection is included in the original permit. However, if you fail inspection and abandon the permit, then re-pull a new permit 6 months later, you pay the full permit fee again.
Gray areas and exemptions are minimal, because nearly all retrofit work alters structural wind resistance. Small cosmetic shutters (the kind that bolt on without any fasteners to the house) are arguably exempt from permitting in some jurisdictions, but in Greer, the city takes the conservative stance that ANY exterior shutter — even cosmetic panels — requires a permit and model-number documentation, because inspectors want proof the panels won't become projectiles in a hurricane. Secondary water barrier (peel-and-stick membrane applied under shingles during reroof) is often bundled with a roof replacement permit; if you're doing retrofit water barrier only (not replacing shingles), it still needs a permit to verify installation depth and nail spacing. Roof-to-wall straps installed during new construction or roof replacement are part of that permit; if you're retrofitting straps to an existing roof (common in older Greer homes built in the 1970s–1990s without modern uplift connections), you must pull a separate permit because you're improving an existing structure. Impact windows can sometimes be viewed as a like-for-like replacement if you're just swapping an old single-pane window for a new impact unit in the same frame — but Greer's building department requires a permit either way, to verify the new window is tested and installed correctly. Garage-door bracing is always permitted; you cannot do it as a maintenance item. The city does allow owner-builders, so if you own the home and live there, you can pull the permit and do the work yourself (or hire a contractor to do it) — but the permit must be in your name, and you're responsible for code compliance.
Greer's location in the Spartanburg County piedmont (not coastal lowcountry) shapes some local permitting nuances. Wind speeds are lower than Charleston or the Lowcountry (which see 100+ mph hurricanes), so the design wind speed is around 90 mph, not 115+ mph. However, Greer sits in the foothills with older residential stock — many homes built in the 1970s–1990s lack roof-to-wall straps entirely and have plywood roof decks fastened with just nails, not screws. Soil is piedmont clay, not the coastal pluff mud or sandy soils; this affects foundation and settling. The building department is familiar with retrofit requests and approves them quickly if plans are clear. Greer does not have a special-overlay district for wind or historic preservation that would slow down permits (unlike some historic downtowns). The city's inspection staff is reasonably knowledgeable on wind-retrofit details, but don't expect them to know every shutter manufacturer's test data — that's your engineer's job. One local quirk: Greer's online portal is not as mature as larger South Carolina cities (Charleston, Columbia); you may need to hand-deliver or mail your application rather than uploading it online. Call the building department to confirm current submission method before you spend time scanning documents.
Next steps: Call the City of Greer Building Department (verify the phone number on the city website, as it may change) and ask for a wind-retrofit permit application. Gather your scope (list every item you want to retrofit — e.g., 'replace 6 windows, install roof-to-wall straps on east and west roof, secondary water barrier under south roof section, garage-door bracing'). If the scope is simple (a few shutters, one window), you can often describe it on the application and skip a detailed drawing. If it's comprehensive (whole-house retrofit), hire a structural engineer or a retrofit specialist (many insurance agents have lists) to stamp a one-page design letter specifying strap locations, fastener sizes, window models, and secondary-barrier details. Submit the permit application, engineer's letter (or drawings), contractor license (if applicable), and fee. The city will issue a permit within 2–4 weeks. Schedule your first inspection when you're ready to install (give the inspector 2–3 days' notice). Do NOT close up the work (shingles, siding, drywall) until the city has inspected and signed off. Once final inspection is complete, request a copy of the inspection report — frame it or save it digitally. This document is proof your home has been retrofitted and inspected, which is what your insurance company needs to grant a discount.
Three Greer wind / hurricane retrofit scenarios
South Carolina Building Code wind design and why 90 mph matters for Greer
The South Carolina Building Code adopts the IBC and ASCE 7-16 (or later) for wind-load design. Greer, in Spartanburg County, is classified as a non-special wind zone by the USGS hazard maps — meaning the basic design wind speed (3-second gust) is approximately 90 mph, per ASCE 7. That's lower than coastal zones (which see 110+ mph), but it's still significant and exceeds typical maintenance wind speeds (70 mph). Your roof-to-wall straps and fasteners must be rated to resist the uplift and lateral forces generated by a 90 mph sustained gust.
Older Greer homes (pre-2000) were often built under older IBC editions that had looser uplift requirements or were built with no code at all. A 1980s ranch might have roof deck fastened with just nails (not screws), rafters toenailed to the top plate (not strapped), and no secondary water barrier — all of which fail under 90 mph wind. When you retrofit, the city requires your new work to meet current code (IBC R301), which means every rafter gets a hurricane strap with two bolts or eight 16-penny nails, and secondary barrier is nailed at 6 inches on center. This is a step-up from what was there, which is why permits and inspection are non-negotiable.
Why does it matter? Because a roof blow-off or structural failure in a hurricane can cost $100,000+ in damage, plus loss of shelter and life safety risk. The permit and inspection process ensures your retrofit actually works. A hired engineer signs off on the design; the city inspects installation; you have proof your home is stronger. When you file an insurance claim or sell the home, that proof is invaluable.
Insurance discounts and the retrofit ROI: why wind-retrofit costs often pay back in 3–7 years
Most homeowner insurance policies in South Carolina offer discounts for hurricane/wind retrofits. State Farm, Nationwide, SCPIE, and Federated typically offer 5–15% annual premiums savings if you provide proof of retrofit (engineer's design letter, building permit final-inspection report, and sometimes a post-retrofit home-inspection report from a licensed wind-mitigation inspector). The discount is immediate — you apply it when you renew your policy. On a $1,200/year homeowner policy, a 10% discount is $120/year, meaning a $3,000 retrofit pays for itself in 25 years. But if your retrofit qualifies for a 15% discount, that's $180/year, and the 3-year payback kicks in.
Some insurers (particularly those writing a lot of SC coastal property) are more generous with discounts if your retrofit is comprehensive (roof-to-wall straps + secondary barrier + impact windows + garage-door bracing). A full retrofit can earn a 20% discount on some policies, meaning a $15,000 retrofit paying for itself in 5–7 years through premium savings alone. Plus, if you never have a claim, you keep saving that discount year after year — the retrofit continues to pay dividends for the life of your ownership.
The building permit final-inspection report is your proof. Keep it in a safe place (scan it digitally too) and provide a copy to your insurance agent when you renew. Some agents will ask for an OIR-B1-1802 (Miami-Dade form) to verify fastening details, but in Greer, the city inspection report and engineer's letter are typically sufficient. If your agent asks for extra documentation, ask your engineer to provide a summary of fastener types and spacing — a half-page letter will satisfy most carriers.

Common questions
Do I need an engineer stamp for hurricane shutters in Greer?
No, not for simple bolt-on shutters. However, Greer's building department requires a permit for any exterior shutter — even cosmetic panels — and wants documentation of the shutter model and fastener details. If your shutters are self-designed or custom-built, an engineer stamp is recommended. For manufactured shutters (e.g., Protective Products, HurricaneShutter.com), the manufacturer's test report and installation guide are sufficient; your permit application just needs the model number and a photo showing where they'll be mounted.
Can I install impact windows myself as the homeowner, or do I need a contractor?
You can install them yourself under the owner-builder exemption (SC Code § 40-11-360), but you still need to pull a permit with the city. The permit application requires you to name the window models and locations; an inspector will visit to verify the installed windows match the approved models and are sealed per the manufacturer's detail. Many homeowners hire a contractor for the window install (it's finicky and requires proper sealant and fastener spacing), but the permit is under your name as the owner-builder.
What's the difference between a roof-to-wall strap retrofit and a secondary water barrier, and do I need both?
A roof-to-wall strap (hurricane strap) connects the rafter or truss to the top plate of the wall with metal brackets and bolts/nails, resisting upward wind forces that can lift the roof off. A secondary water barrier is a peel-and-stick membrane applied under shingles before re-shingling, which provides a second line of defense against wind-driven rain leaks. They address different failure modes. You can do either one alone, but a full retrofit includes both. If your home is older (pre-2000), the straps are the higher priority; if your roof is leaking or you're replacing shingles anyway, the secondary barrier is a no-brainer add-on.
How long does the Greer permit process take for a wind retrofit?
Permit approval typically takes 5–10 business days for simple scopes (windows only) and 10–14 days for structural work (roof straps, secondary barrier). Work itself takes 1–4 weeks depending on scope and contractor availability. Final inspection can take another 1 week if you call it in promptly. Total timeline from permit application to final sign-off is usually 3–7 weeks. Over-the-counter approval (same-day) is rare unless your application is extremely simple and complete.
What if the city inspector finds unpermitted retrofit work during a later inspection (e.g., roof repair)?
The city can issue a stop-work order and require removal of the unpermitted work, then re-installation under a new permit. This can cost 30–50% more than the original job because you're re-doing work, paying new permit fees, and incurring labor to remove and reinstall. The home's resale can be blocked if the unpermitted work is not addressed. Worst case, your homeowner insurance could deny a claim if the unpermitted retrofit is deemed the cause of damage (e.g., improperly fastened straps that failed in a wind event).
Do I get an insurance discount for hurricane retrofit work?
Yes. Most homeowner policies offer 5–15% annual discounts if you provide proof of retrofit (permit final-inspection report and engineer's design letter). A few insurers offer up to 20% if the retrofit is comprehensive (roof straps + secondary barrier + impact windows + garage-door bracing). Discounts are applied at policy renewal. On a $1,200/year policy, a 10% discount saves $120/year — so a $3,000 retrofit pays for itself in 25 years, and a $15,000 full retrofit pays back in 5–7 years through discount savings.
Is there a grant or subsidy for hurricane retrofits in South Carolina?
South Carolina does not have a statewide retrofit grant program like Florida's MyHome grant (which offers up to $10,000). However, some insurers and non-profits occasionally offer retrofit rebates or cost-sharing programs; ask your insurance agent or search the SC Department of Insurance website for any active programs. Tax credits are generally not available at the state level, though energy-efficient windows may qualify for federal tax credits (ITC) — consult your CPA.
What if I'm buying a home in Greer and the seller discloses unpermitted retrofit work?
South Carolina requires sellers to disclose unpermitted work on the Transfer Disclosure Statement. If retrofit work (e.g., old roof straps installed without permit) is disclosed, your lender may require it to be removed and re-installed under permit before they'll close. Your home inspector should flag any retrofit signs (straps, newer shingles, impact-window frames) and recommend verification with the city that it was permitted. If the work is not permitted and you want to keep it, you can sometimes negotiate with the seller to obtain the permit retroactively (often difficult and expensive) or to reduce the sale price to offset the cost of removal and proper retrofit.
Can I use a contractor from another state (like North Carolina) to do my Greer retrofit?
A contractor must be licensed in South Carolina to work in Greer. An out-of-state contractor can partner with a licensed SC contractor, but the SC contractor is the one pulling the permit and responsible for code compliance. If you hire an out-of-state roofer or window installer, verify they have an SC license or are working under a licensed SC general contractor. The city will ask for contractor license verification at permit time.
What happens at the permit inspection — what is the city actually checking?
For roof-to-wall straps: the inspector counts nails/bolts, measures spacing (should match your plan, typically 6 feet on center), and verifies fasteners are into the top plate. For secondary water barrier: they check nail spacing (typically 6 inches), overlap distance (usually 6 inches minimum), and that the barrier is sealed at edges. For impact windows: they verify the model numbers match the approved permit, check that the frames are sealed with sealant per the manufacturer detail, and confirm fastener spacing. For garage-door bracing: they inspect the bracing kit is fully installed and fastened per the manufacturer and your design. The inspector is looking for code compliance and workmanship — slippy installation (missing fasteners, improper spacing) will fail and require correction before final sign-off.
