La Gorce Island, Miami Beach Luxury Real Estate Guide (2026)

Last updated: July 2026

La Gorce Island real estate sits on a single guard-gated island in Biscayne Bay, on the bay side of Miami Beach near La Gorce Country Club. The island holds a fixed, small inventory of single-family homes reached through one guarded bridge entrance off North Bay Road, and that single point of entry is the feature that shapes both pricing and how a buyer should underwrite a purchase here. Turnover is low because the lot count is capped, so in most years only a handful of homes change hands.

For buyers, the island offers two distinct products. There are waterfront lots with private dockage and direct bay frontage, and there are interior lots that carry the same address and security but no water. Waterfront carries a premium over interior, and that gap has widened as Miami Beach land values have risen. This guide covers what defines the island, the housing stock, price context, and the specific items to underwrite before writing an offer, from seawall condition and flood elevation to island security dues and tidal access to the open ocean.

What defines La Gorce Island

La Gorce Island was built in 1924 as a dredged and filled island within Miami Beach, named for John Oliver La Gorce of the National Geographic Society [1]. It is a single residential island in Biscayne Bay, bounded by Indian Creek and the surrounding bay, with one bridge connecting it to the North Bay Road corridor. That bridge is staffed, and vehicle access runs through a guarded gate.

The island is a fixed community of roughly 59 single-family homes, of which about 33 are waterfront [2]. Because the plat is fully built out, there is no new lot supply. When a buyer talks about scarcity here, it is literal: the denominator does not grow, so the market is driven by how many of those homes list in a given year rather than by new construction adding to the pool.

A homeowners association, in place since the 1940s, oversees island security and shared upkeep [1]. For a buyer, that means underwriting recurring island dues as a line item, separate from city and county obligations, and confirming what those dues fund and whether any assessments are pending.

Waterfront versus interior lots

The practical divide on the island is water versus no water. Waterfront lots deliver bay frontage and, in most cases, a private dock, which is the core of the value proposition here [1]. Interior lots share the gate, the streets, and the address, but the buyer is paying for land and location rather than dockage and open views.

If boating and direct bay access are the reason for the purchase, the interior lots are a different asset, and they should be underwritten against interior comps rather than waterfront ones. Mixing the two in a valuation is one of the more common errors on islands like this.

The housing stock and teardown dynamics

The homes range from restored Mediterranean-era estates to newer modern construction, reflecting a century of building on the same lots [1]. That mix creates a teardown-and-rebuild dynamic that a buyer should price in directly.

On a scarce waterfront island, land often carries most of the value, and an older house on a prime lot can trade close to lot value less demolition. That has two consequences. First, when you underwrite an aging home, model both the as-is scenario and the rebuild scenario, because your exit may depend on the next buyer's willingness to rebuild. Second, factor in that new construction in a coastal high-hazard area triggers current building code, elevation, and flood requirements, which raise the cost and timeline of a ground-up project relative to a renovation.

Across Miami Beach, the same forces that price other bayfront enclaves apply here. For broader context on the barrier-island market that surrounds the island, see the Miami Beach neighborhood overview.

Price context and the waterfront premium

Because so few island homes trade in any given year, single-property sales can swing island-level averages, so it helps to read prices against the wider La Gorce area rather than from one or two closings. In the broader La Gorce neighborhood, the median sale price was about 3.9 million dollars in mid-2026, with median price per square foot near 957 dollars [3]. Those figures cover a larger area than the island itself, so treat them as directional context, not as island comps.

On the island specifically, list prices for waterfront estates generally run well above interior asking prices, and marquee compounds have been marketed at the very top of the Miami Beach range. Rather than anchor to a single headline number, underwrite each home against its own comparable set: waterfront to waterfront with similar frontage and dockage, interior to interior. Days on market in the surrounding La Gorce area have run long, above 200 days in recent Redfin data [3], which tells a buyer that this is a market where measured negotiation is normal and speed is rarely the deciding factor.

For buyers weighing the island against other guard-gated waterfront options, the tradeoffs differ by location. A community like Key Biscayne offers a separate barrier-island profile with its own access and insurance considerations, and comparing the two side by side is a useful exercise before committing.

What a buyer should underwrite

The island is desirable for the same reasons it demands careful diligence. The value drivers, water, dockage, and low-density seclusion, are also the sources of the risks a buyer should price.

Seawall condition

On a waterfront lot, the seawall is a capital asset with a finite life. Ask for the age, the last inspection, and any repair or replacement history. A failing or undersized seawall can be a six-figure item, and increasingly it is tied to permitting and elevation requirements that make replacement more involved than a like-for-like fix. Have a marine or structural professional assess it during the inspection period.

Flood zone, elevation, and insurance

The island sits in a coastal flood area, so confirm the FEMA flood zone and the home's finished-floor elevation, and request an elevation certificate. Those two inputs drive flood insurance pricing more than almost anything else. Given the size of these homes, wind and flood coverage is a material annual cost, and it should be quoted from an actual carrier before closing, not estimated. An older home at a low elevation and a newer home built to current code can carry very different insurance profiles on the same street.

Island dues and association

Budget the island security and association dues as a recurring line item, and request the association's current financials, dues history, and any pending or planned assessments [1]. On a small island, shared costs such as gate staffing, the bridge, and street upkeep are spread across a limited number of homes, so per-home obligations can move when a major repair comes due.

Tidal and bridge access to the ocean

For boat owners, confirm the route from the dock to open water, including tidal draft at the dock and any bridge clearances along the way to Government Cut and the ocean. "No-fixed-bridges" access, meaning a clear path to the ocean without a low fixed bridge limiting vertical clearance, is a specific value factor for larger vessels, and it should be verified against the actual boat rather than assumed. Confirm permitted dock length and any dock or lift restrictions as part of diligence.

Mapping these items before you make an offer is the core of a disciplined purchase here. If you want a structured walkthrough of the diligence and financing sequence, start with a buyer consultation.

Frequently asked questions

How many homes are on La Gorce Island?

The island is a fixed community of roughly 59 single-family homes, with about 33 of them on the water [2]. Because the island is fully built out, there is no new lot supply, so inventory in any given year depends on how many owners choose to list.

Is La Gorce Island gated and guarded?

Yes. Access runs through a single bridge with a staffed, guarded entrance, and a homeowners association oversees island security and shared maintenance [1]. Owners pay recurring island dues that fund that security and upkeep.

What is the difference between waterfront and interior lots?

Waterfront lots offer direct Biscayne Bay frontage and, in most cases, a private dock, which is the main driver of value [1]. Interior lots share the gate, streets, and address but have no water, so they trade at lower prices and should be valued against other interior sales rather than waterfront ones.

What should I underwrite before buying on the island?

Focus on seawall age and condition, FEMA flood zone and finished-floor elevation, wind and flood insurance quoted from a real carrier, island association dues and any pending assessments, and, for boaters, tidal draft and bridge clearances on the route to the ocean. Model both an as-is and a rebuild scenario for older homes.

Are island prices the same as the published La Gorce numbers?

No. Widely published figures such as the roughly 3.9 million dollar median for mid-2026 cover the broader La Gorce neighborhood, not the island alone [3]. Island homes, especially waterfront, generally price above that, so use the neighborhood data as context and rely on island-specific comps for an actual valuation.
