Waterfront Land and Building Due Diligence

A waterfront lot can look ready to build on and still come with setbacks, wetlands, flood elevation requirements, septic limits, or shoreline restrictions that change what fits on it. Existing homes have their own version of this: an addition or major renovation may trigger current flood and building rules. These guides walk through the questions to answer before you buy land or plan a project near the water.

Buildability is decided locally and by state and federal agencies, not by a listing description. Plan to involve a surveyor, the county or city planning and building office, the local floodplain administrator, the health or environmental agency that handles septic permits, and a real estate attorney when the answer affects whether you buy.
