Fisher Island's 'No More Land' Story Has A Ten-Acre Asterisk

Ask anyone selling on Fisher Island why prices keep climbing and you'll hear the same three words: no more land. The island is 216 acres, fully built, and once The Residences at Six Fisher Island delivers, there is nowhere left to put a shovel in the ground. That story is mostly true. It is also missing a very specific ten-acre exception that spent the first half of 2026 working through Miami-Dade County Commission meetings, two lawsuits, and a mayoral eminent domain filing.

If you're weighing Fisher Island against Manalapan, Palm Beach, or another ultra-luxury address, the fixed-supply argument does a lot of the persuading. It deserves a closer look before it does yours.

The Last New Address, Confirmed

The confirmed part of the story is straightforward. The Residences at Six Fisher Island, an 11-story, 50-unit tower on the island's last developable residential parcel, reached its final floors by spring 2026 and is targeting delivery in late 2026 or early 2027. Miami-Dade County issued the building permit on February 20, 2026, carrying a construction consideration of $154.3 million, following the project's September 2024 groundbreaking. The development team includes Related Group, BH Group, Teddy Sagi, and Wanxiang America RE Group, with architecture by Kobi Karp and interiors by Tara Bernerd & Partners.

Units span three to eight bedrooms, starting around 3,872 square feet, with pricing that begins near $15.5 million and reaches roughly $90 million for the penthouse. Owners get more than 55,000 square feet of private amenities, sunrise and sunset pools, a spa, a pickleball court, a private restaurant, and butler service, plus a membership in the Fisher Island Club that comes with the unit. Once this tower delivers, every residential parcel on the island's 216 acres will have been built. On that point, the marketing language and the permit records agree.

The Ten Acres That Complicate The 'Never Again' Claim

What Six Fisher Island's completion does not settle is a separate ten-acre marine fuel terminal on the island's north shore, in continuous operation for nearly a century, supplying fuel to PortMiami's cargo and cruise ships. Its zoning has nothing to do with condominiums. It remains zoned for heavy industrial use, and changing that requires the county's sign-off, not the island's.

The site's recent history reads like a case study in how quickly a "no more land" market can stop being one:

• January 2025: TransMontaigne Partners, the Denver-based operator, agreed to sell the terminal for $180 million to HRP Fisher Island LLC, a venture including HRP Group, Related Group, and Raycliff Capital.
• The plan: demolish the depot and build two 13-story condo towers under the name One Fisher Island, with penthouses priced near $100 million and total project costs near $2 billion.
• October 2025: Fisher Island's Community Association reached an agreement with HRP, securing rights to roughly four of the ten acres and design input in exchange for supporting the redevelopment. Around the same time, county commissioners authorized pursuing eminent domain if a purchase couldn't be negotiated.
• May 2026: Miami-Dade County and HRP reportedly reached agreement in principle on a $400 million buyout, with the county paying $200 million upfront and $200 million over time.
• Weeks later, the deal collapsed. On June 5, 2026, Mayor Daniella Levine Cava announced the county would proceed with eminent domain after negotiations "concluded without an acceptable agreement," according to NBC Miami.
• June 16, 2026: The County Commission voted to amend the property description and formally advance the eminent domain process, with Commissioner Raquel Regalado casting the lone no vote, per The Real Deal.
• Since then: Fisher Island's Community Association and Fisher Island Club have sued the county twice, arguing the seizure is unconstitutional and that a county purchase would breach the October 2025 agreement with HRP, according to Axios Miami.

"I cannot support this item, but I hope I'm wrong." — Miami-Dade Commissioner Raquel Regalado, the lone vote against advancing the eminent domain process

The appraisal fight alone could take years to resolve, a real estate attorney told The Real Deal, because fair market value on a parcel this contested will be the central dispute. Until it resolves, one of two things happens. Either the county wins and the depot stays exactly where it has sat for a century, or HRP prevails and two towers with $100 million penthouses land at an address international buyers were told would never see new construction again. Either outcome changes the supply story materially. Neither has happened yet.

Why A Single Deal Can Move Fisher Island's Median

Fisher Island's other 2025 headline was ZIP code 33109 dethroning Atherton, California, after eight straight years, to become the country's most expensive ZIP code, with a median sale price of $9.5 million, up 65% year over year, according to PropertyShark's ranking published in October 2025. That number is accurate. It also comes from a sample small enough that a handful of transactions can move it. A rebuttal published by Palo Alto Online after the ranking landed made the same point from Atherton's side: Fisher Island has roughly 600 housing units and typically 10 to 20 annual sales, compared with Atherton's more than 2,700 homes and 50 to 70 annual transactions. A market that thin does not need a trend to move its median. It needs one closing.

None of this means the market is soft. It means it moves in bursts. Three Mansions on Fisher Island homes changed hands in May 2026 at a combined asking price of $105.5 million, a deal negotiated by Madar Group USA and reported by The Real Deal. A sale of that size, on an island expecting only a handful of closings all year, can single-handedly define the story real estate coverage tells for months. So can a single legal ruling on ten acres zoned for fuel tanks.

What This Means If You're Comparing Fisher Island To Other Enclaves

Buyers weighing Fisher Island against Manalapan, Palm Beach, or another Palm Beach County address need the full cost picture, not just the entry price on a portal. Ownership here comes bundled with a separate Fisher Island Club membership, carrying roughly $350,000 in equity initiation plus $38,000 to $53,000 in annual dues, on top of building-level maintenance that runs roughly $1,500 to $8,000 a month depending on the building and unit size. At the $10 million ownership tier, all-in annual carrying costs including HOA fees, club dues, insurance, and property taxes have been estimated at $215,000 to close to $1 million a year, depending on the property. None of that is unusual for an ultra-luxury island market. What's unusual is how much of it sits outside the single number most listings lead with.

The fixed-supply pitch is not wrong about Six Fisher Island. It is incomplete about the island as a whole, and the incomplete part is currently sitting in front of a Miami-Dade County Commission that has already voted once and a court docket that has seen two lawsuits filed this year.

Fisher Island Supply Questions, Answered

Will Fisher Island ever see new residential construction again? On the island's existing residential parcels, no. The Residences at Six Fisher Island occupies the last developable residential site. The open question sits on a separate ten-acre industrial parcel, the fuel terminal site, where two condo towers were proposed, opposed by Miami-Dade County, and are now the subject of an eminent domain fight the county voted to advance in June 2026.

Why did Fisher Island's median sale price jump so much in 2025? PropertyShark attributed the 65% year-over-year jump to a run of high-end condo and single-family sales in a market with very few total transactions each year, which means a handful of large deals can swing the median substantially in either direction.

Why are average days on market so much longer in 2026 than a year ago? Redfin data for the three months ending May 2026 shows average days on market near 267, up from about 90 a year earlier. Paired with MLS data showing zero closed sales in June 2026 and none year-to-date, the pattern points to a market trading in occasional large transactions rather than a continuous flow of sales.

Fisher Island rewards buyers who read the fine print before they read the median.
