Key West vs. Florida statewide
The Florida state median for a 2,500 sf custom home runs around $290/sf. Key West runs roughly 50% above that — making it a top-of-market luxury submarket.
High-wind code (HVHZ in South FL), impact glass, and concrete-block walls are non-negotiable cost drivers.
What drives cost in Key West
- →Local permit cadence. Typical Florida permit window is 3–7 months. Metro submarkets within Florida often run longer than rural counties.
- →Climate-driven assemblies. Hot-humid, 1A/2A climate zone. That dictates insulation, roof, and HVAC line items.
- →Trade availability. Key West pricing reflects local labor density. Booked-out trades in this market drive 5–15% premium during peak season.
- →Land excluded. Key West land prices vary 5–10x by neighborhood. Budget land separately and add to these construction totals.
