Closed $/SF figures use the 4 recorded sales of these units in the 24 months to Nov 2, 2026; a median needs three. Floor, line and size are the record's. Views and orientation are not in it and are not shown.

Line 17 closed highest per square foot: a median $1,880/SF over 3 sales in 24 months. The largest typical unit is line 17, a median 532 sf over 5 units seen, recorded as studios.

How this is drawn: a unit's floor and line come from its MLS unit number alone (5614 is floor 56, line 14). A cell exists only where the MLS has recorded a listing, a closing or a lease; a blank means no record was seen, not that no unit exists. Column widths follow each line's median recorded living area. Pre-construction towers and buildings with a thin record have no drawing.

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 9 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

Due 2031

Due by statute by December 31, 2031, 30 years after 2001, then every 10 years.

What the deadline means
  • Miami-Dade sets 25 years for condo buildings within three miles of the coastline, which would be December 31, 2026.
  • Based on year built 2001 (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
