Who writes manufactured-home insurance in South Carolina
South Carolina Wind and Hail Underwriting Association covers wind/hail on coastal manufactured homes when private carriers exclude named storms. A separate non-wind HO policy from Foremost or SC Farm Bureau is required. Inland Piedmont placements run 50-60% under coastal.
Carrier appetite is materially different from stick-built homeowners insurance. The big-name national writers most South Carolina homeowners default to — State Farm, Allstate, Liberty Mutual — either don't quote manufactured homes at all or quote them through limited regional subsidiaries at non-competitive rates. The specialist carriers (Foremost and American Modern) almost always quote 25-40% cheaper than what a generalist agent will offer you first.

What a South Carolina mobile-home policy actually covers
An HO-7 policy in South Carolina covers six standard categories: the dwelling (the unit itself, plus permanently attached additions like decks, skirting, and awnings), other structures (detached sheds, carports), personal property, loss of use, personal liability, and medical payments to others.
Critical wrinkle: the dwelling is typically valued at "stated value" or "actual cash value" — meaning depreciation is deducted at claim time — unless you specifically buy "replacement cost on dwelling" as an endorsement. Replacement cost endorsements raise premium 10-20% but materially change what you receive after a total loss. For South Carolina units that face frequent hurricanes, the endorsement is almost always worth it.
Liability coverage usually starts at $100,000 per occurrence; bumping to $300,000 typically adds $40-80/yr and is worth it for any household with a pool, trampoline, or dog.
What drives South Carolina premium up or down
South Carolina's dominant peril (hurricanes) sets the baseline. Beyond that, six factors swing the quote 30-60%:
Wind mitigation is the single biggest lever in South Carolina. Carriers offer codified credits — typically 25-45% off — when the home has properly engineered tie-downs, anchoring straps, roof-to-wall attachments, and verified compliance documentation. The inspection costs $75-200 and pays back in year one.
- Year of manufacture — post-1994 (Wind Zone II/III HUD update) units quote materially cheaper
- Foundation type — permanent masonry/concrete foundation cuts premium 10-20% vs. pier-and-beam
- Roof age and condition — most carriers now write ACV not RCV on roofs >10 yrs
- Heat source — wood stove, pellet stove, and space heaters add 15-25% surcharge
- Park vs. owned land — owned-land placements quote 5-15% cheaper than park-lot units
- Distance to coast / WUI zone — varies enormously by ZIP within the same county
Common exclusions and gotchas in South Carolina
Flood is not covered by any standard manufactured-home policy in South Carolina — you need a separate NFIP policy if your unit sits in a flood-prone zone. The NFIP residential rate map (FEMA Risk Rating 2.0) prices each unit individually now; quotes vary from $400 to $4,000+ depending on elevation and base flood depth.
Earth movement (earthquake, landslide, sinkhole) is excluded statewide and requires a separate endorsement or standalone policy. In South Carolina the relevant peril is hurricanes — confirm whether earthquake or land-movement coverage is meaningful for your specific location before paying for the endorsement.
Cosmetic-only roof damage is increasingly excluded by South Carolina carriers writing in hail-prone counties. Read the cosmetic damage exclusion (CDE) endorsement carefully — it means a hailstorm that dents but doesn't penetrate the roof won't trigger replacement.
Vacant homes (unoccupied >60 days) lose coverage under most South Carolina policies. If you snowbird, travel for work, or own the unit as a rental, you need either a vacancy permit endorsement or a landlord/dwelling fire (DP-1 or DP-3) policy.
How to quote South Carolina mobile-home insurance the right way
Don't start with a generalist agent who runs you through their primary carrier first. Go direct to a specialist or to a captive agent who actively writes manufactured-home risks in South Carolina. Foremost and American Modern are usually the fastest paths to a competitive quote.
Before you call, have: VIN/serial number of the unit, year of manufacture, length and width (singlewide / doublewide / triplewide footprint), foundation type, anchoring documentation if available, roof age and material, heating source, and exact South Carolina address with ZIP. Quotes given without these details are placeholder numbers — the bind-time premium will be higher.
Get at least three quotes. South Carolina manufactured-home rates vary materially carrier to carrier — we routinely see 30-45% spreads between the cheapest and most expensive quote for the same unit, same address, same coverage limits.
