Are Florida Keys homes elevated above flood level

Some are, some are not. Many Florida Keys homes are elevated above flood level, particularly newer construction, while others were built before current flood standards and may sit below base flood elevation. Elevation varies by property age, location, and construction type.

This page is informational and reference-only. It is not a listings page and does not include property search results.

Key factors that affect home elevation

  • Year built and building code requirements at the time of construction
  • Base flood elevation assigned to the property
  • Construction type, including stilted, raised, or slab-on-grade homes
  • Flood zone designation and regulatory updates
  • Substantial improvement or post-storm reconstruction history

Geographic variation within the Florida Keys

  • Upper Keys neighborhoods with a mix of older slab homes and elevated construction
  • Islamorada areas with elevated homes along with legacy ground-level properties
  • Marathon communities with varied elevations based on development era
  • Lower Keys locations influenced by shallow elevation and tidal conditions
  • Key West homes affected by historic districts and zoning constraints

Actual elevation should be verified at the individual property level using surveys or elevation certificates.
