Admiralty House

If you've been searching for a beachfront condo on Marco Island, chances are Admiralty House has already popped up in your research. And for good reason. Sitting dead center on Marco's famous Crescent Beach at 140 Seaview Court, this 18-story building has been one of the island's most recognizable addresses since it was built in 1974 — and it continues to attract buyers looking for a legitimate Gulf-front lifestyle, not just a postcard version of one.

This guide breaks down everything a serious buyer or investor needs to know: the building, the floor plans, the pricing, the HOA, the rental rules, and how it stacks up against the alternatives.

What Is Admiralty House?

Admiralty House is a 200-unit, pet-free beachfront condominium tower on Marco Island, Florida. Built in 1974 and rising 18 stories above Crescent Beach, it offers direct Gulf of Mexico access and some of the most sought-after views on the island's coastline.

The building is divided into north and south sections, with six units per floor — which keeps the hallways quiet and gives the whole place a more private, boutique feel than many comparable high-rises. There's an on-site manager, 24/7 security, and a well-funded HOA that keeps the building in consistently good shape.

Every unit comes with a private balcony, one covered parking space, an exterior storage locker, and an additional under-air storage space on each floor.

Floor Plans and Unit Sizes

There are five floor plans at Admiralty House, split between one-bedroom and two-bedroom configurations:

One-Bedroom Units

  • 1BR / 1.5BA — approximately 604–610 sq ft under air
  • Available with either island/canal views or Gulf-facing views depending on the unit's position in the building

Two-Bedroom Units

  • Four separate two-bedroom floor plans, all 2BR / 2BA
  • Sizes range from approximately 837 to 896 sq ft under air
  • Two of the four plans are end-unit layouts with wraparound balconies — these are the most coveted in the building
  • The other two-bedroom plans split between island-view bedrooms and all-Gulf-facing bedrooms

Half the units in the building have direct Gulf views; the other half overlook Marco Island's canals, tropical landscaping, and the broader island landscape. Both orientations have their fans. Gulf-view units command higher prices, but canal-view owners often point out that they get sunrises and a quieter, less wind-exposed balcony.

Location: Why Crescent Beach Matters

Marco Island is a small, four-by-six-mile barrier island near the southern tip of Florida's Gulf Coast, about an hour south of Naples. It's home to more than 30,000 winter residents — mostly "snowbirds" who migrate from the Midwest and Northeast between November and April to escape the cold.

What separates Marco from other Gulf Coast destinations is its pace. There are no major theme parks, no convention centers, and no strip-mall tourist zones. The vibe is low-key, outdoorsy, and genuinely relaxed. People come to fish, paddle, eat seafood, and sit on the beach without the noise and crowds you'd find at larger resort destinations.

Crescent Beach, where Admiralty House sits, is widely regarded as one of Florida's finest stretches of coastline — white sand, calm Gulf waters, and a wide, well-maintained beach. Admiralty House's position in the middle of that beach (rather than at either end) means you're within walking distance of restaurants, coffee shops, and casual island retail. Empire Bagel Factory, Doreen's Cup of Joe, and several well-reviewed seafood restaurants are all an easy walk away.

Amenities

This is where Admiralty House tends to win over buyers who compare it to other buildings in the same price range.

The pool is the standout feature — at 60 by 30 feet, it's the largest beachfront pool on Marco Island, and it's heated so you can use it year-round. It sits right at the edge of the beach, which means you're looking straight out at the Gulf while you swim. On a winter afternoon when the temperature is 78 degrees and the sun is setting over the water, it's hard to beat.

Beyond the pool, the property includes:

  • Tennis courts (with pickleball also noted in some listings)
  • BBQ/tiki area near the pool
  • Social room and library
  • Car wash area
  • Laundry rooms on every floor
  • 24/7 security and on-site management
  • Cable TV and WiFi included in the monthly condo fee
  • Beach chair lockers for owners — no hauling chairs to the beach every day
  • Bike and walking trail access nearby

The building's Social Committee organizes regular events — movie nights, book club, bridge — which matters more than it sounds if you're spending six months a year there and want to actually know your neighbors.

Recent building-wide improvements include a renovated lobby, refreshed hallways, and an updated social lounge. These aren't cosmetic touches — they signal an HOA that's actively maintaining and reinvesting in the property.

Pricing: What to Expect in 2025

Based on recent MLS activity, Admiralty House condos for sale are currently priced between approximately $525,000 and $899,000, depending on floor, view, and unit size.

Here's a general breakdown:

  • One-bedroom units (604–610 sq ft): Roughly $525,000–$599,000. Canal/island-view units tend to come in at the lower end; Gulf-facing units push higher.
  • Two-bedroom units (837–896 sq ft): Generally $650,000–$899,000. End units with wraparound balconies and high-floor Gulf views command the top of that range.
  • Price per square foot: Recent sales data reflects approximately $857/sq ft on average.
  • Days on market: Units have averaged around 200+ days to sell, which gives buyers room to negotiate — this is a patient market, not a frenzy.

Many listings are offered turnkey furnished, which is a practical advantage if you want to rent or move in immediately after closing without furnishing a beach condo from scratch.

HOA Fees and What They Cover

Monthly condo fees at Admiralty House range from approximately $833 to $1,267 per month, scaled to unit size. That's a meaningful line item, but here's the important context: the fees cover nearly everything except electricity.

What's included: water, sewer, trash, cable TV, WiFi, building insurance, exterior maintenance, landscaping, pool, amenities, management, and reserves.

What's not included: electricity, and your own homeowner's contents insurance.

The reserve fund is the number that separates Admiralty House from a lot of comparable buildings. The HOA holds at least $2 million in reserves, which means buyers can reasonably expect not to be hit with large special assessments down the road. For anyone who has owned in a building with underfunded reserves — and then received a $15,000–$30,000 surprise assessment letter — that distinction is significant. After Florida's new condo reserve laws took effect following the Surfside collapse, a well-funded reserve isn't just nice to have; it's a legal and financial necessity.

Investment Potential: The Rental Market

If you're planning to offset ownership costs with rental income when you're not using the unit, Admiralty House is well-positioned for it.

Minimum rental period: 30 days. This fits the snowbird model that drives Marco Island's rental demand from roughly November through April. Monthly winter rentals in a beachfront building at the center of Crescent Beach are consistently in demand. Many owners report the same tenants returning year after year — people who find a unit they love and lock in the same weeks each season.

The 30-day minimum means you're targeting monthly renters rather than weekend vacationers. For most owners, that's actually a better model: fewer turnovers, less wear on the unit, lower management overhead, and more predictable seasonal income.

Platforms like Airbnb and VRBO are permitted, within the 30-day minimum rule.

How Does Admiralty House Compare to Other Marco Island Condos?

The most common comparison is Gulfview, which sits nearby on Crescent Beach. The two buildings are often mentioned together, and for good reason — they're similar in age, location, and price range. The key difference most buyers notice: Gulfview allows one pet up to 20 lbs, while Admiralty House is strictly pet-free. If you travel with a dog, that's a dealbreaker for Admiralty and a reason to look at Gulfview instead.

Other buildings worth exploring in the same category include South Seas Club, Crescent Beach Club, and Surf Club — each with its own tradeoffs on price, amenities, rental rules, and views.

Things to Know Before You Buy

The units are compact. Even the two-bedrooms top out under 900 square feet. If you're downsizing from a large house and expect spacious rooms, the footprint is an adjustment. That said, when daily life revolves around a beach, a heated Gulf-front pool, and a balcony with those views, the square footage inside stops being the thing you think about.

No pets allowed. Full stop. This is the most common dealbreaker for buyers who are otherwise sold on the building.

Verify reserve fund status before closing. The reserves have historically been strong here, but always confirm with current HOA documents — specifically the most recent reserve study and financial statements.

Check for any pending special assessments. Florida's updated condo laws require buildings to be fully funded on specific structural components. Ask your real estate agent to pull the HOA's latest disclosures before you make an offer.

Get a unit inspection. Even in a well-maintained building, individual units vary widely. Some have been recently renovated with granite, stainless appliances, and updated baths. Others are original 1970s interiors. Price accordingly.

The Bottom Line

Admiralty House isn't trying to be the flashiest building on Marco Island. What it offers instead is something more durable: a genuine beachfront location at the heart of Crescent Beach, a well-run HOA with real reserves, amenities that hold up against newer competition, and a rental market that makes the numbers work for investors and part-time owners alike.

If Marco Island is on your radar as a second home or income-producing property, this building belongs on your shortlist — and probably near the top of it.
