What building in Key West actually involves, and how SeaTop delivers plans ready for local review.
Wind & flood code
The Keys (Monroe County) combine strict flood-elevation rules (often V / coastal high-hazard zones) with island logistics. SeaTop homes ship complete and install fast, even on constrained sites.
Permitting
Permitting runs through the City of Key West Building Department (Monroe County). Our factory-built, sealed systems are documented for their elevation and wind requirements.
