Inside Williams Island
An entire 84-acre gated island in the Intracoastal makes up Williams Island, the Aventura community long marketed as the Florida Riviera. Nine residential towers plus the Mediterranean Village villas surround a shared Island Club whose 27,000-square-foot spa, sixteen tennis courts, marina, and restaurants function like a standing resort, with a shuttle looping the grounds. Pricing spans approachable older towers to grand penthouses, so the island serves everyone from first-time buyers to longtime residents trading up without leaving.
On Island Blvd in Williams Island, Williams Island is a residential condominium, holding nine towers + villas. We follow this building unit by unit: each line, floor and exposure trades at its own level, so the listings below are sorted by status — available, under contract and recently closed — rather than blended into a single average.
The layouts seen in recent MLS activity run from studios up to 7-bedroom residences. Shared facilities on record for the building include child play area, guard at site, lobby secured, pickleball, tennis court(s) and bike/jog path — worth confirming with the association which are covered by the monthly dues and which carry their own fees.

Questions Buyers Ask About Williams Island
Which association documents should I review before buying at Williams Island?
Request the current budget, the reserve study, at least a year of board minutes, the rules and regulations, and a written statement of any special assessment that is approved or under discussion. Florida's condo-safety laws now require milestone structural inspections and structural integrity reserve studies for buildings of three or more stories, so ask where Williams Island stands on both.
Does Williams Island allow pets?
Pet policy is set by the Williams Island association and can limit the number, size or type of animals — and a board vote can change it. Get the current rule in writing before you make an offer; we request it as a standard step on every condo purchase we handle.
What leasing rules apply to owners at Williams Island?
Minimum lease length, how many times a year a unit may be leased, tenant approval and any waiting period for new owners are association decisions. If you plan to rent the unit out, verify the current policy first; the rental and leased tabs on this page show the lease activity recorded here.
How do view lines and floor height affect value at Williams Island?
Inside one tower, price follows the stack: exposure, view corridor, floor height and whether the line is a corner unit all matter. Compare closed prices by bedroom count in the market report, then ask us which lines in Williams Island face which direction before you build a shortlist.
Does a unit at Williams Island come with parking?
Parking arrangements differ by building and sometimes by unit — assigned spaces, valet, or spaces conveyed as limited common elements. Confirm how many spaces transfer with the specific residence and whether guest parking or storage costs extra.
How does Gromadzki Real Estate price a unit in Williams Island?
Building first: closings in the same line and bedroom count, then nearby floors, then comparable towers in Williams Island. The association's health — reserves, assessments and insurance — gets equal weight, because it shapes the monthly cost of ownership as much as the purchase price does.
What is the street address of Williams Island?
The building's address is Island Blvd, Aventura, FL 33160 — part of Williams Island. The map lower on this page pins its exact location.
