FEMA flood zone

AE

Inside FEMA's Special Flood Hazard Area. A federally backed mortgage requires flood insurance here.

What the zone means
  • The 1% annual chance ("100-year") flood area, with a base flood elevation set.
  • Base flood elevation 8 ft (NGVD29).
  • The zone is a map line, not a premium. Ask the association for its master flood policy, and get a flood quote for the specific unit before you commit.

Milestone structural inspection

Turned 30 in 1951

The statute's first deadline for a building this age was December 31, 2024, then every 10 years.

What the deadline means
  • Based on year built 1921 (county record). The statute counts from the certificate of occupancy date, which can differ.
  • The association must give every owner the inspector's summary. Ask for it, and for the structural integrity reserve study, before you commit.

Fla. Stat. § 553.899(3) ↗ and Miami-Dade recertification ↗, read Oct 9, 2026. What the deadline means for buyers
