The setting

Building in Key Biscayne.

Key Biscayne is a barrier island with its own Village government and Building, Zoning and Planning Department. Much of the island lies in FEMA flood zones, so substantial improvements to existing homes can trigger requirements to meet current flood elevation standards, often called the 50% rule. Oceanfront and bayfront work may involve coastal construction regulations, and condominium renovations require association approvals, insurance certificates, work-hour limits and elevator and loading-dock scheduling. Our completed oceanfront residence renovation at Continuum South Tower in Miami Beach reflects the same condominium coordination discipline.
