Ask Lori Lee: Grand Strand Edition — Do I Need Flood Insurance If My Home is Outside a Flood Zone?

I get some version of this question from almost every out-of-state buyer at some point during their search: "The listing says it's not in a flood zone, so I don't need flood insurance, right?" It's a reasonable assumption. It's also one of the more common misunderstandings I run into, especially with buyers relocating from states where flood insurance was never really part of the homebuying conversation.

The honest answer is: not being in a high-risk flood zone means you're probably not required to carry flood insurance. It doesn't mean you're not exposed to flood risk. Those are two different questions, and conflating them is where a lot of new Grand Strand homeowners get caught off guard. Let's separate them properly.

What "Flood Zone" Actually Means on a Grand Strand Property

Every property in the U.S. gets a flood zone designation on FEMA's Flood Insurance Rate Maps (FIRMs), and that designation is what everything else in this post hinges on. The zones fall into two broad categories:

Special Flood Hazard Areas (SFHAs) are the high-risk zones. Around here, that mostly means Zone AE (at least a 1% annual chance of flooding, with a base flood elevation FEMA has calculated) and Zone VE (coastal high-hazard areas exposed to storm-driven wave action — think oceanfront and near-oceanfront parcels).

Non-Special Flood Hazard Areas — most commonly labeled Zone X — cover everything FEMA considers lower probability. This is the "not in a flood zone" designation buyers usually mean when they ask this question. It's a real, meaningful distinction. It is not the same thing as zero risk.

Why Flood Insurance Outside a Flood Zone Still Matters Here

This is the part that surprises people. According to FEMA's own flood risk data, nearly a third — 29% — of National Flood Insurance Program claims filed between 2014 and 2024 came from properties outside designated high-risk flood areas. FEMA also reports that 99% of U.S. counties have experienced a flood event at some point over the past 20 years. Flood risk doesn't respect a line drawn on a map; it follows drainage, elevation, storm track, and how saturated the ground already is when the next system comes through. So I always advise my clients to explore flood insurance even though the property is outside a flood zone.

The Grand Strand's geography makes this especially relevant. Much of Horry County sits low and flat, with slow-draining soil and a dense network of canals, retention ponds, and the Intracoastal Waterway managing water that has nowhere fast to go. A property can sit comfortably in Zone X and still take on water during a slow-moving tropical system that dumps a foot of rain over 48 hours — that's a rainfall and drainage event, not necessarily a "the ocean came in" event, and Zone X doesn't protect against it.

Standard homeowners insurance policies exclude flood damage entirely, regardless of what zone you're in. That's a separate, standalone policy — either through the NFIP or a private flood insurer — and it's the one piece of coverage a lot of relocating buyers don't realize they need to shop for separately.

What Your Lender Can (and Can't) Require

Federal law is specific here, and it's worth knowing the actual rule rather than assuming. If a property sits in a Special Flood Hazard Area and you're using a federally regulated or federally backed mortgage, the lender is required by law to make you carry flood insurance for the life of the loan. There's no lender discretion involved — it's a mandatory purchase requirement tied directly to the flood zone.

Outside an SFHA — in Zone X, for example — that federal mandate doesn't apply. But individual lenders can still choose to require it as a condition of the loan, particularly if the property has a documented flood history or sits near a known drainage concern.

That's a lender-by-lender, sometimes loan-by-loan, decision rather than a blanket rule. If flood insurance requirements are a deciding factor for you on a specific property, that's a conversation for your mortgage lender to walk through with the actual loan file in front of them — I'm glad to connect any buyer I'm working with to a local lender who handles this daily.

What South Carolina Law Requires Sellers to Disclose

South Carolina updated its Residential Property Condition Disclosure Statement in 2023 specifically to close a gap around flood transparency, and the current form (administered by the SC Department of Labor, Licensing and Regulation Real Estate Commission) asks sellers to disclose several flood-specific items directly to buyers:

Whether the property has known flood hazards, wetlands, or flood zone designations affecting it; whether it currently carries public (NFIP) or private flood insurance; any flood insurance claims filed on the property during the seller's ownership, including dates and repair details; any flood-related repairs made that were not filed as insurance claims; whether the property previously received federal flood disaster assistance through FEMA, the SBA, or HUD; and whether the property has been assessed for a beach nourishment project.

That last point matters more here than it would almost anywhere else in the country — beach nourishment assessments are a real, recurring line item for a meaningful share of Grand Strand oceanfront and near-oceanfront properties, and it's worth understanding before you're the one paying it.

This disclosure form is a genuinely useful document. Read it in full, and don't treat the flood section as boilerplate.

What This Looks Like in Real Grand Strand Numbers

Cost is usually the next question, and it varies more than people expect because FEMA moved away from a one-size-fits-zone pricing model. There's a cost-saving option a lot of buyers don't realize exists: FEMA confirms that when a home sells, the existing NFIP flood insurance policy on the building can be transferred directly to the new buyer rather than requiring a brand-new policy from scratch. Assuming the seller's policy can genuinely work out cheaper than starting over. A new policy is typically rated using a fresh elevation certificate — or, absent one, a conservative default that assumes worse elevation than the home may actually have — while an assumed policy carries its own already-established rating forward. A good buyer's agent checks early in the process, before you're ever quoted on a new policy, whether the seller already carries a policy on the home, so assumption is on the table as an option from day one rather than something you discover after you've already paid for new coverage.

How to Check Before You Write an Offer

A good buyer's agent treats this as standard due diligence, not an afterthought. I check the FEMA flood zone designation on every property I show, the same way I check square footage or HOA status — it should already be part of the conversation by the time you're deciding whether to write an offer, not something you're researching for the first time after you're already under contract.

A few minutes of homework before you're under contract saves a lot of surprise later: look up the address on FEMA's Flood Map Service Center at msc.fema.gov to see the official current zone designation, then cross-check it on Horry County's GIS flood viewer, which sometimes reflects local drainage and supplemental flood data the national map doesn't show at the same resolution. Ask for the seller's completed Residential Property Condition Disclosure Statement and actually read the flood section rather than skimming it.

Then, on any property you're seriously considering, I connect you directly with a local insurance broker to weigh your actual options.

Where to Go From Here

None of this is a reason to avoid a property, and it's not a reason to assume every Zone X home is a hidden problem. It's simply information worth having before you're the one signing at closing instead of asking questions from the buyer's side of the table. I'm not a licensed insurance agent, and I won't tell you what coverage to carry or what you personally should do about it — that's a conversation for a local insurance broker who can look at flood zone, elevation, construction, and your specific risk tolerance together. If you'd like an introduction to one I trust, I'm happy to make that connection for any property you're seriously considering along the Grand Strand.
