What Should I Know About Buying Waterfront Property?

Waterfront luxury properties offer an exceptional lifestyle and hold strong appeal at resale — but they come with a distinct set of legal, structural, and insurance considerations that inland luxury properties do not.

Water rights: The legal definition of where the owner's property ends and the public waterway begins varies by state and by waterfront type. In Florida, for example, the state owns the submerged lands beneath navigable waters. Dock and slip rights, seawall maintenance obligations, and water access rights are all governed by a combination of state law, local regulation, and the specific recorded plat. Buyers should have a real estate attorney review the specific water rights associated with any waterfront property before closing.

Flood zone designation: Waterfront properties are almost always in federally designated flood zones. The specific flood zone designation — and the associated flood insurance requirements — affects the annual cost of ownership materially. In South Florida, flood insurance premiums have increased significantly in recent years and represent a meaningful carrying cost for waterfront properties.

Hurricane and wind exposure: Oceanfront and bay-front properties in hurricane zones are exposed to significantly higher wind and storm surge risk than inland properties. Construction standards matter — buildings constructed after 2004 generally meet significantly higher hurricane resistance standards than older buildings. Buyers should evaluate the specific hurricane protection features of any property in a hurricane zone.

Erosion and seawall condition: Seawalls protect waterfront properties from erosion and storm damage but require regular maintenance and periodic replacement. Seawall replacement is expensive — often $500 to over $1,000 per linear foot — and the obligation to maintain and replace the seawall typically falls on the property owner. Buyers should have the seawall condition professionally inspected before closing.
