Flood zones in St. Johns Lake
Homes sold in the past 12 months, by FEMA flood zone
None of the 20 homes sold here in the past 12 months sit in a high risk flood zone on FEMA’s current map, so most lenders do not require flood insurance. All 20 sit in the minimal risk zone. A zone describes the land, not the house, and flood insurance is still available and worth pricing.
Have a home in St. Johns Lake in mind. Text me the address at 843-718-6338 and I will pull its flood zone and the elevation certificate if one exists, and connect you with a licensed insurance agent for a flood quote.

What to know before you buy in St. Johns Lake
Dues
Many Johns Island neighborhoods have an association with dues. I confirm the dues and rules for every home before you make an offer.
City or county
Parts of Johns Island are in the City of Charleston and much of it is unincorporated Charleston County. Which one a home sits in affects taxes, trash and what you can build, so I confirm it for every home before you make an offer.
Flood and insurance
Marsh and creek front streets on Johns Island can sit in flood zones while homes nearby do not, and insurance costs follow.
Living in St. Johns Lake
Day to day
The Angel Oak, farm stands, marsh and creeks are all on Johns Island, with Kiawah, Seabrook and Folly Beach close by.
Getting around
Maybank Highway and River Road are the main routes toward James Island and downtown Charleston, and rush hour traffic on them is the biggest complaint I hear. I have buyers drive the commute before they commit.
