A Charleston beach cottage used to mean a simple wood house on a barrier island, close to the sand, built like it might have to be rebuilt. After Hurricane Hugo in 1989, it more often means a house on stilts that had a conversation with FEMA.
Folly, Sullivan's, Isle of Palms, and to a different luxury pitch Kiawah and Seabrook, all started with seasonal and working island houses. Salt, wind, and flood were always the brief. Hugo made the brief into code: elevation, continuous load path, and insurance that can dwarf a mortgage.
Pre-Hugo and post-Hugo are different species
If the house is low and charming and original, I want a structural engineer and a flood quote before anyone writes a love letter. If the house is tall and modern under a cottage listing photo, I want the elevation certificate, the V-zone rules, and whether the ground level is breakaway walls or a garage someone converted. The word cottage is doing too much work in island MLS remarks.
STR, parking, and the myth of easy income
Island towns have their own short-term rental fights. Folly's cap went to court in 2026. Do not buy a beach cottage as an Airbnb thesis without reading the town's actual ordinance. This chapter is the house. Also: wind deductibles, named-storm deductibles, and roofs. A cedar shake fantasy on a barrier island is a maintenance religion.
Questions I get on this house type
Is a Sullivan's Island cottage the same as a Folly cottage?
Different towns, different prices, different STR and zoning politics. The raised-wood idea is shared. The paperwork is not.
Should I buy a pre-Hugo house?
Only with eyes open on elevation, insurance, and retrofit cost. Some are treasures. Some are uninsurable hobbies. The inspection and the flood quotes decide, not the porch swing.
