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.

Read the full record 4 paragraphs and 15 facts, every figure from the MLS and county record

Yacht Club at Portofino is a 34-story tower at 90 Alton Rd in South Beach, completed in 1999. The Miami-Dade Property Appraiser lists 359 residential units, averaging 1,040 SF of living area. It was developed by Related Group and designed by CFE Architects. The condo archive records it as waterfront (bay).

On November 2, 2026, 12 units were listed for sale, asking $625K to $1.8M (median ask $1,122/SF across 12 listings). One more was under contract. 21 sales closed between November 2, 2025 and November 2, 2026, from $625K to $1.8M, a median $1,047/SF, after a median 96 days on the market. In the 12 months before that, 10 sales closed at a median $1,048/SF, essentially the same level. The MLS holds 122 closed sales here going back to 2019; among years with three or more sales, 2024 set the high at a median $1,141/SF. That 12-month median ranks 23rd of the 83 South Beach buildings with at least three sales in the same window. Two-bedrooms made up 22 of the 31 sales in the last 24 months, at a median $1,225,000.

Four units were offered for rent at $7,500 to $15,000 a month. 57 leases were signed over the same 12 months, at a median $5,800 a month (range $3,200 to $16,800). Leases outnumbered sales 3 to 1 over that year, so renters are a large share of who lives here.

About 38% of the residences are owner-occupied according to county records.

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

Due 2029

Due by statute by December 31, 2029, 30 years after 1999, 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, 2024.
  • Based on year built 1999 (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
