How to use this profile

  1. Scan the hazard list. Anything rated Major or Extreme is the next page to open.
  2. Read the insurance note — flood and earthquake are usually separate policies.
  3. Look up your ZIP, then confirm the address on the official maps linked from each hazard page.

You've got a closing date next month, and the house you're looking at sits on a quiet street in Beaufort. The seller's disclosure mentions a dehumidifier and a French drain. That's your first clue. South Carolina's hazard profile isn't one problem — it's a stack of them. Flooding and hurricanes both rate 4 out of 5 on the state's risk scale. Those are the two that should drive your inspection list and your insurance budget.

Flooding here isn't just a coastal issue. FEMA's flood maps show inland counties along the Pee Dee and Edisto rivers with their own high-risk zones. Hurricanes bring storm surge to Charleston and Myrtle Beach, but they also drop feet of rain in Columbia and Greenville. The South Carolina Emergency Management Division publishes evacuation zones and storm surge maps. Check your address before you fall in love with the kitchen. If you're east of I-95, flood insurance is not optional in my book — even if your lender doesn't require it.

Extreme heat and severe storms also score 4 out of 5. That matters more than you think. A house with a 15-year-old AC unit and no shade trees will cost you every July. Severe storms mean straight-line winds, hail, and frequent tornado warnings. Tornadoes themselves rate a 3, and earthquakes a 3 — the Lowcountry has a real fault history. But you can't fix a fault line. You can fix a roof.

If I had one weekend and a thousand dollars, I'd spend it on a flood elevation certificate and an inspector who knows how to spot hurricane straps. Then I'd pull the seller's insurance claims history. South Carolina is a great place to own a home. It just asks you to respect the water and the wind. Start with SCEMD's site, then call your agent. That's the briefing.
