Bay Isles Harbor, Longboat Key | Danielle Gladding & Co.

Behind the Bay Isles gate, there is a second gate.

That is not a figure of speech. At the south end of Bay Isles sits Bay Isles Harbor — and to reach it you pass through the community's main guarded entry gate, then a second private gate into Harbor itself. A gate within the gate. Most people who know Longboat Key would call it the most exclusive section inside Bay Isles, and the rest of the picture explains why: 67 architect-designed homes on four quiet streets of wide canals, an active boating community with bridge-free access out to the Gulf, where every home enjoys bay views and lush landscaping. A park runs the length of Harbor Sound Drive, popular with residents for biking, walking their dogs, and birding. Real privacy, and still genuinely neighborly. Double-gated, small, designed, on the water. That is the character of the place in a sentence.

We are Danielle Gladding & Alison Kanter, a Sarasota mother-daughter team. Danielle has been in this market 50 years — a Realtor since 1981, a Broker since 1987 — and she and her husband Nick live inside Bay Isles, in Queens Harbour on the north side. Bay Isles Harbor sits at the south end. Opposite sides of the same community, behind the same gate. Neighbors. What follows is the focused version of what we tell buyers about this one rare address, written from the inside.

A Gate Within the Gate

Start with the security, because it is the first thing that sets Bay Isles Harbor apart. Bay Isles itself is a manned, guarded, gated community. Bay Isles Harbor adds a second private gate of its own at the south end, so residents pass through two layers of access control to reach home. For a buyer who puts privacy and security ahead of nearly everything else, that arrangement is rare even among Florida's most exclusive barrier-island addresses.

The result is a quiet that is hard to describe until you stand in it. No through traffic. No one driving past who does not live there. Sixty-seven homes on four streets, at the south end of the island, and nothing passing through.

Sixty-Seven Homes, Four Quiet Streets

Bay Isles Harbor is exclusive because it is small by design. Sixty-seven architect-designed homes along four quiet streets makes this one of the most tightly held enclaves on Longboat Key. These are not production builds. They are individually designed, with lush landscaping and bay views.

Scarcity is what makes the address difficult to buy into. Sixty-seven homes, owners who tend to hold for the long term, and properties that often move quietly when they do become available. A small, designed, waterfront community behind two gates does not come up often — and when it does, it rarely feels like a public listing for long.

Wide Canals and Bridge-Free Gulf Access

Bay Isles Harbor is a boating community in the truest sense. The four streets are built around wide canals — generous water that makes maneuvering and dockage easier than the narrow cuts in many waterfront neighborhoods — with bridge-free access out to Sarasota Bay and on to the Gulf of Mexico.

Bridge-free matters more than most buyers expect. In a great many Florida waterfront neighborhoods, a fixed bridge between your dock and open water quietly caps the vessel you can keep at home. That constraint does not exist here. What you can run out of Bay Isles Harbor is governed by your dock and your draft, not by a bridge clearance.

This is where we spend the most time with buyers. Canal width, dock configuration, water depth at your particular slip, and how each lot sits on its run to the Bay all change both the value and the daily experience. Two homes on the same street can be very different purchases. A listing photo will not tell you which is which. Fifty years of walking this water will.

The Park, the Privacy, and the Neighborly Feel

One of the quiet pleasures of Bay Isles Harbor is the park running the length of Harbor Sound Drive. Residents use it constantly — biking, walking their dogs, birding along the water. It is the kind of shared green space that turns a collection of houses into an actual community.

That is the balance buyers tell us they love here. Real privacy paired with a genuinely neighborly feel. The enclave is small enough that people know each other, and the streets, the canals, and the park stay exactly as residents expect them to.

The Privileges That Come With the Address

Buying in Bay Isles Harbor means buying into the broader Bay Isles privileges, on top of the boating, bay-view, architect-designed life that belongs to this enclave specifically.

• Private deeded access to the Bay Isles Beach Club at 2111 Gulf of Mexico Drive — a gated Gulf-front beach reserved for Bay Isles owners, with tiki huts, a large covered pavilion, barbecue stands, volleyball nets on the sand, and an ice machine. Functionally, a private beach.

• Privileged access, at this time, to the adjacent Longboat Key Club & Resort — golf, a nationally regarded tennis program, pickleball, a spa, a fitness center, the marina at The Moorings, and multiple dining venues.

• Two layers of gated security — the main guarded Bay Isles entry gate and Bay Isles Harbor's own private gate.

• A walkable, year-round setting — the Harbor Sound Drive park, continuous sidewalks, and the Longboat Key Bike Trail running nearly the full length of the island just outside the gate.

None of it is far from the rest of life. St. Armands Circle is a short drive south and Downtown Sarasota is just beyond it across the John Ringling Causeway. Bay Isles Harbor is exclusive, not isolated.

Who Bay Isles Harbor Is Really For

Danielle Gladding has been a Realtor since 1981 and a broker since 1987. Working alongside Alison Kanter, she helps buyers weigh what a waterfront purchase actually costs to own — dock depth at low tide, seawall age, insurance exposure, and what the association covers versus what lands on the owner. Bay Isles Harbor is not the right fit for every buyer, and that is worth saying plainly. It is the right fit if several of these ring true:

• You want an architect-designed single-family home with bay views — not a production build, not a condominium.

• Privacy and security come first, and a private second gate inside the community gate is exactly the kind of thing you have been looking for.

• An active boating life on wide canals with bridge-free Gulf access is central to how you want to spend your days.

• You value real privacy paired with a small, neighborly community of only 67 homes.

• The Harbor Sound Drive park and a walkable, dog-friendly enclave matter to your daily routine.

• You are buying for the long term — a primary residence, a legacy home for grandchildren, or both.

• You appreciate that a 67-home enclave behind two gates, on a barrier island where land does not expand, tends to protect long-term value.

If that is you, the hard part is not deciding you want Bay Isles Harbor. The hard part is being ready when one of the 67 becomes available.

Why It Helps to Have a Broker on the Inside

This is the part that cannot be matched from the outside. Danielle is not studying Bay Isles Harbor from across town. She lives inside Bay Isles, behind the same gate, and has spent 45 years in this market. She knows which lots sit best on the wide canals, which homes have been thoughtfully updated, how the enclave is run, and which neighbor is quietly thinking about selling before any of it reaches the MLS. In a community of 67 homes, that early knowledge is often the difference between buying the right home and watching it sell to someone else.

Alison brings the other half. Analytical precision, lot-by-lot and association-by-association due-diligence discipline, and the tech-forward rigor that keeps a high-stakes purchase grounded. Instinct and evidence, balancing each other.

A Private Conversation Costs Nothing

If Bay Isles Harbor is the address you have your eye on — or you want a clear read on whether it truly fits you better than another part of Bay Isles — the most useful next step is a confidential, no-pressure conversation.

Tell us what you are trying to accomplish and what your timeline looks like. We will tell you which of the 67 homes are worth your time, where the tradeoffs actually sit, and when something is likely to become available before it reaches the market. Twenty minutes on the phone, no pitch.

A private conversation costs nothing.

The Due Diligence We Walk Every Bay Isles Harbor Buyer Through

Buying an architect-designed home inside a double-gated enclave carries layered governance: the master Bay Isles Association, the Beach Club association and its dues, and the Bay Isles Harbor Association — a five-member Board of Directors overseeing day-to-day management of the enclave. Each layer affects your monthly carry and your resale.

Beyond the associations, the things that matter most on a waterfront lot are dock permitting, water depth at your specific slip, flood elevation, insurance, and how the particular home sits on its canal and its run to the Bay. We walk every buyer through all of it — association and reserve health, deeded Beach Club access, pending capital projects, and the water itself — before anyone signs anything.

With only 67 homes, the worst outcome is overpaying for the wrong lot when the right one was a street away.

Frequently Asked Questions

What is Bay Isles Harbor on Longboat Key?

Bay Isles Harbor is a small, double-gated enclave of 67 architect-designed homes at the south end of Bay Isles, a guarded gated community on Longboat Key, Florida. Set along four quiet streets of wide canals with bridge-free access to Sarasota Bay and the Gulf of Mexico, it is an active boating community where every home enjoys bay views and lush landscaping, with deeded access to the Bay Isles Beach Club and privileged access to the adjacent Longboat Key Club & Resort.

How many homes are in Bay Isles Harbor?

Bay Isles Harbor contains 67 architect-designed homes arranged along four quiet streets, making it one of the smallest and most exclusive enclaves on Longboat Key. Because the community is small and owners tend to hold their homes for the long term, properties here rarely reach the open market and often sell quietly when they do.

Is Bay Isles Harbor gated?

Yes — Bay Isles Harbor is double-gated. Residents pass through the main guarded Bay Isles entry gate and then a second private gate into Harbor itself, creating two layers of access control. That arrangement gives the enclave a level of privacy and security that is rare even among Florida's most exclusive barrier-island communities.

Why is Bay Isles Harbor considered the most exclusive part of Bay Isles?

Bay Isles Harbor is widely considered the most exclusive part of Bay Isles because it is a small, designed enclave of just 67 architect-designed homes on wide-canal waterfront lots, set behind a second private gate inside the larger guarded Bay Isles gate. The double-gated security, the limited number of homes, the architect-designed character, the bay views, and the active boating setting with bridge-free Gulf access combine to make it one of the most coveted addresses on the island.

Does Bay Isles Harbor have bridge-free access to the Gulf?

Yes — Bay Isles Harbor offers bridge-free access from its canals to Sarasota Bay and on to the Gulf of Mexico. Bridge-free access matters because a fixed bridge between a dock and open water limits the height of vessel an owner can keep at home, a constraint that does not apply here. Buyers should still confirm water depth at the specific slip for their particular vessel, which we review with every client.

Is Bay Isles Harbor a boating community?

Yes — Bay Isles Harbor is an active boating community built around four streets of wide canals with access to Sarasota Bay and the Gulf of Mexico. The wide canals make dockage and maneuvering easier than the narrow cuts found in many waterfront neighborhoods, which is a meaningful advantage for residents who keep a boat at home.

Does Bay Isles Harbor have a park or shared amenities?

Yes — a park runs the length of Harbor Sound Drive in Bay Isles Harbor and is popular with residents for biking, walking their dogs, and birding. Residents also have private deeded access to the Bay Isles Beach Club on the Gulf at 2111 Gulf of Mexico Drive and, at this time, privileged access to the adjacent Longboat Key Club & Resort, with golf, tennis, a marina, a spa, and dining.

How is Bay Isles Harbor managed?

Bay Isles Harbor is managed by a five-member Board of Directors that oversees day-to-day management of the enclave, in addition to the broader master Bay Isles Association and the Bay Isles Beach Club association. Buyers should review all applicable association rules, fees, and reserves as part of their due diligence, which we walk through with every client.

How much does a home in Bay Isles Harbor cost?

Pricing in Bay Isles Harbor varies significantly by lot position, canal frontage, home size and design, and whether a residence has been updated. Because this is an enclave of only 67 architect-designed homes with limited inventory, we do not publish firm numbers in evergreen content. For an accurate, confidential, current reading on Bay Isles Harbor pricing and availability, contact Danielle Gladding and Alison Kanter directly.

Is Bay Isles Harbor a good place to buy a second home or legacy property?

Bay Isles Harbor is one of Longboat Key's most desirable options for an architect-designed single-family second home or legacy property. A 67-home double-gated enclave, an active boating setting on wide canals with bridge-free Gulf access, bay views, deeded beach access, Florida's tax-favorable residency, and limited barrier-island inventory make it especially attractive for long-term and multi-generational ownership.
