5 units in the record sit outside this grid (212, 220, 221, 318, 324): 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.

Built in 1939, Artecity Governor is a three-story low-rise at 435 21st St in South Beach. The Miami-Dade Property Appraiser lists 62 residential units plus three commercial units, averaging 652 SF of living area.

On November 2, 2026, two units were listed for sale, asking $249K to $330K ($448 to $570/SF). Three sales closed between November 2, 2025 and November 2, 2026, from $243K to $328K, a median $419/SF, after a median 108 days on the market. The year before saw one closed sale. The MLS holds 27 closed sales here going back to 2019; among years with three or more sales, 2023 set the high at a median $592/SF. That 12-month median ranks 73rd of the 83 South Beach buildings with at least three sales in the same window.

One unit was offered for rent at $2,550 a month. 14 leases were signed over the same 12 months, at a median $2,500 a month (range $1,950 to $4,000). Leases outnumbered sales 5 to 1 over that year, so renters are a large share of who lives here.

About 6% of the residences are owner-occupied according to county records, which points to an investor-heavy ownership base. The association is managed by KW Property Management & Consulting.

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 1969

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 1939 (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
