Closed $/SF figures use the 19 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 07 closed highest per square foot: a median $1,805/SF over 5 sales in 24 months. The largest typical unit is line 03, a median 2,158 sf over 17 units seen, recorded with 3 bedrooms.

5 units in the record sit outside this grid (901-902, 1503-04, 3405/06, 3405/6, PH1): penthouse, townhouse or ground-level numbers, or lines seen only once or twice.
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.

Icon South Beach rises 42 floors at 450 Alton Rd in South Beach and was completed in 2005. The Miami-Dade Property Appraiser lists 274 residential units, averaging 1,787 SF of living area. It was developed by Related Group and designed by Sieger Suarez Architects. Interiors are by YOO Studio. The condo archive records it as waterfront (bay). MLS and county records use the legal name Icon Condo.
On November 2, 2026, five units were listed for sale, asking $1.1M to $3.2M (median ask $1,526/SF across 5 listings). Two more were under contract. 10 sales closed between November 2, 2025 and November 2, 2026, from $950K to $24M, a median $1,465/SF, after a median 109 days on the market. In the 12 months before that, 11 sales closed at a median $1,274/SF, so the median rose 15%. The MLS holds 111 closed sales here going back to 2019; among years with three or more sales, 2025 set the high at a median $1,722/SF. That 12-month median ranks 14th of the 83 South Beach buildings with at least three sales in the same window. Two-bedrooms made up 13 of the 21 sales in the last 24 months, at a median $2,200,000.
Three units were offered for rent at $6,000 to $17,000 a month. 28 leases were signed over the same 12 months, at a median $10,500 a month (range $5,700 to $24,000). Leases outnumbered sales 3 to 1 over that year, so renters are a large share of who lives here.
About 49% of the residences are owner-occupied according to county records. Association rules on file: pets yes (owners & tenants); no short-term rentals; minimum lease 6 months; up to two leases a year. The association is managed by alsoto@effectivepropertyservices.com. I have four of its association documents on file, including the Declaration of Condominium and the Lease Application.
