Homestead has both Special Flood Hazard Areas and Zone X, and the city’s Building Safety Division keeps the flood zone maps. For property inside the city it issues a Flood Zone Determination Letter at no charge, and Development Services may already have an Elevation Certificate on file for your house. Both are worth having before you talk to buyers, because flood insurance is part of every buyer’s math.
Florida also requires a seller of residential property to give the buyer a flood disclosure at or before signing the contract. It asks whether the seller knows of flood damage during their ownership, has filed a flood insurance claim, or has received assistance for flood damage, such as from FEMA (section 689.302, Florida Statutes). This is general information, not legal advice.
