What governs this parcel
One of the artificial islands of the Venetian chain. On the Venetian Causeway, City of Miami Beach.
- Seawall — City of Miami Beach. The owner is responsible. New seawalls must meet a minimum of 5.7 feet NAVD, or 4.0 feet NAVD if designed to support future elevation to 5.7, and a repair at or above $300 per linear foot is substantial enough to trigger that standard. After a citation the clock is 60 days to show progress and 730 to finish. The full sequence.
- Flood elevation. Elevation certificates have been required since 1995 for new construction and substantial improvement, and the county publishes a searchable database for homes built after that. A house older than that with no substantial improvement usually has none. The 50% rule turns a large renovation into an elevation project by threshold rather than negotiation.
- Getting a boat to open water. The Venetian Causeway bridges are federally regulated: 12 feet closed on the west bridge, 5 feet on the east, both opening only on the hour and half hour from 7am to 7pm daily.The clearances and the citation.
- Any association or transfer requirement. Several communities in this market run a mandatory owners association with an approval step and a fee at purchase — the single-family equivalent of condominium board approval. We have not verified one for this island and are not going to assume it either way.What those requirements look like where they are documented, and what to ask before you offer.
Where this sits
- All nine island groups side by side — the same county record, the same exclusions
- What to check before offering — the seven authorities and the order they bite
