Quick answer: After any Presidential disaster declaration in South Carolina, FEMA’s Hazard Mitigation Grant Program (HMGP) — managed by the SC Emergency Management Division (SCEMD) — funds long-term risk-reduction projects at a 75% federal / 25% non-federal cost share, and elevating a flood-prone home is a core eligible project. Homeowners can’t apply directly: your county or municipality applies with your property included. The 25% share can be covered by an ICC insurance assignment, in-kind contributions, or state match funds — which is how Charleston elevations get funded at far more than 75%.
Where the Money Comes From
HMGP is authorized under Section 404 of the Stafford Act — the federal law that governs disaster response. When the President declares a major disaster in South Carolina, a percentage of what FEMA spends on that disaster is set aside for mitigation: projects that reduce the next disaster’s damage rather than repair the last one’s. SCEMD administers that money for the state.
The detail most Charleston homeowners never hear: eligibility is statewide. Per SCEMD, once a declaration exists, all counties in South Carolina may apply for HMGP funds — not just the counties named in the declaration. Hurricane Helene’s 2024 declaration, driven largely by devastation in the Upstate, still generated mitigation funding that Lowcountry jurisdictions could pursue for flood projects. If you’ve been waiting for “Charleston’s turn,” you may already be in it.
To qualify, a project must conform to the State Hazard Mitigation Plan, clear environmental and historic review (relevant for peninsula homes — see the historic elevation guide), provide a long-term solution, and — critically — demonstrate cost-effectiveness through FEMA’s benefit-cost analysis. That last requirement is why flood-prone, repeatedly-damaged homes in mapped hazard areas score well: the avoided future losses are easy to prove. It’s also why Charleston’s repetitive-loss clusters, like the Church Creek basin in West Ashley, are natural HMGP territory.
How a Homeowner Actually Gets In
You never apply to FEMA. The chain runs the other way:
- A disaster is declared anywhere in South Carolina.
- SCEMD opens the HMGP cycle and notifies local governments.
- Your county or municipality assembles an application — a batch of properties proposed for elevation, acquisition, or other mitigation.
- You get included by raising your hand early: contact your floodplain administrator or county emergency management office, state your interest in elevation, and get your property’s loss history documented. Jurisdictions build these lists from homeowners they know about.
- FEMA reviews, awards, and funds flow through SCEMD to the local government, which contracts the work.
Two practical implications. First, the relationships precede the disaster — homeowners already on their jurisdiction’s radar (documented losses, expressed interest, an elevation assessment in hand) are the ones who make the application when a window opens. Second, patience is part of the price: declaration to construction commonly runs a year or more. For a home that must be fixed now, the faster levers are ICC coverage and private financing — with HMGP as the plan for the elevation you know you’ll eventually need.
Solving the 25%: How the Match Actually Gets Covered
The 75/25 split scares homeowners off — 25% of an $80,000–$120,000 elevation is real money. But in South Carolina the match rarely has to be your cash:
- ICC assignment. FEMA permits your Increased Cost of Compliance payment — up to $30,000 from your own flood policy — to serve as the non-federal share of a mitigation grant on the same property.
- State match funds. The SC Office of Resilience (SCOR) has designated disaster-recovery (CDBG-DR) funds specifically to match federally funded mitigation grants — HMGP and FMA both — for activities including buyouts and structural home elevation. SCOR’s post-Helene mitigation programs ran application windows into early 2026, and its match designation is exactly the mechanism that can zero out a homeowner’s share. Cycles open and close; current status is worth confirming at scor.sc.gov.
- In-kind contributions. SCEMD explicitly allows the non-federal share to be met with in-kind services such as donated materials or labor.
Stacked — HMGP’s 75%, ICC’s $30,000, SCOR match funds — a well-positioned Charleston elevation can approach fully funded. The grants hub maps how the pieces fit, and the FMA program offers a parallel annual path with even higher federal shares for repetitive-loss homes.
Is HMGP Your Path?
Strong HMGP candidates in the Lowcountry look like this: a home in a mapped flood zone, a documented loss history (the more losses, the stronger the benefit-cost case), a jurisdiction that knows you’re interested, and an owner who can wait out a government timeline. If that’s your situation — or you’re not sure whether HMGP, FMA, or ICC fits your case — request a free assessment. We’ll confirm your zone and elevation target and give you the realistic project number that any grant application needs anyway.
