The Miami-Dade Property Appraiser lists 181 residential folios under the subdivision 3000 ISLAND BOULEVARD WILLIAMS ISLAND, built 1988–1989.
Nineteen deeded studios under 400 square feet
Nineteen folios at 3000 Island Boulevard measure between 237 and 400 square feet. Each carries one bathroom and no recorded bedroom, an undivided interest in the common elements, and an ordinary unit number in two contiguous runs — 121 to 127 and 321 to 332. Their 2026 assessments sit between roughly $63,000 and $116,000.
These are real, separately deeded homes, not storage lockers and not parking. The distinction matters: Miami-Dade classifies deeded parking spaces with the same residential code as a residence, and a filter that goes by size alone deletes these studios while admitting parking. The test that separates them is the bathroom — every one of these nineteen has one; every parking folio in this community has none.
For a buyer this is a deeded foothold in a gated Williams Island building at studio scale. For an owner comparing “price per square foot at 3000”, it is a warning: nineteen of 181 homes sit far below the median size of 2,154 square feet and will distort any building-wide average.
One of the community’s two oldest towers
Completed 1988–1989, 3000 is among the earliest buildings on the island. It trades at $397 per square foot pooled — effectively identical to 4000 Island Boulevard at $397, which is three years older still. Age alone is not pricing this market.
Where this tower sits on the island
Seven Island Boulevard towers, all inside the same gated community, priced on the same basis — pooled qualified sales since 2023, per square foot. The spread is 2.3×.
| Tower | Homes | Median sale | Per sq ft |
|---|---|---|---|
| 1000 | 319 | $450,000 | $316 |
| 2000 | 274 | $642,500 | $374 |
| 3000 | 181 | $860,000 | $397 |
| 4000 | 180 | $820,000 | $397 |
| 2800 | 159 | $1,250,000 | $488 |
| 7000 | 298 | $1,217,500 | $506 |
| 2600 | 172 | $2,075,000 | $740 |
Across all seven, the county roll records 1,583 homes once deeded parking, storage and cabanas are removed.
Recent qualified sales
Qualified arm’s-length sales only. Transfers the county flags as disqualified are excluded, and 2026 is a part year.
| Year | Qualified sales | Median price | Median $/sq ft |
|---|---|---|---|
| 2023 | 8 | $855,000 | $395 |
| 2024 | 12 | $1,447,500 | $520 |
| 2025 | 11 | $840,000 | $324 |
| 2026 | 2 | $297,000 | $552 |
Read these with the sample size in view. 33 qualified sales in four years is a thin record, and a single large transaction moves a yearly median. The four-year pooled figure of $397 per foot is the more stable number. The 2026 row is two sales of very different homes: a 288 square foot studio at $254,000 and a 1,520 square foot home at $340,000, so its median describes neither.
What to check before you sign
- Confirm the folio, not the unit number. Ask for the folio and read its own sale history and assessment. Building averages hide a 20.2× range in home size here.
- Ask whether parking and storage are deeded separately. In this community they frequently are — 183 folios across the seven towers — which means they carry their own assessment and may or may not convey.
- Ask the association for the milestone inspection status and the reserve study. These are 1988–1989 buildings in Miami-Dade and fall inside the county’s recertification programme.
- Check whether any comparable you are shown was a multi-parcel deed. A single sale covering two combined residences will look like a record per-foot price if it is divided against one folio.

Why do some Williams Island unit counts differ from the county’s?
Because Miami-Dade classifies deeded parking spaces, storage units and cabanas under the same residential code as a home. Across these seven towers the roll carries 183 such folios. Counting them as residences overstates the community by that amount; this page counts only folios with a bedroom or a bathroom.
How many homes are at 3000 Island Boulevard?
The county roll records 181 residential folios, built 1988–1989. There are no non-dwelling folios in this declaration.
What have homes at 3000 Island Boulevard sold for recently?
Pooled across qualified sales since 2023 the median is $860,000, or $397 per square foot. By year the median per foot runs $395 in 2023, $520 in 2024, $324 in 2025, $552 in 2026. There were 33 qualified sales in four years, so treat single-year figures cautiously.
How do prices at 3000 Island Boulevard compare with the rest of Williams Island?
On price per square foot it ranks 3 of the seven Island Boulevard towers (level with 4000), at $397 against a community range of $316 to $740. That is a measurement, not a recommendation: the towers differ in age, home size and floorplan mix, and the right comparison is always the specific floorplan you are being shown.
