Where to Buy Waterfront and Water-View Homes in Marin County

Marin Has Many Waterfronts, Not Just One

When buyers tell me they want a waterfront home in Marin, my first question is always: what kind of waterfront? Because Marin doesn't have a single waterfront market — it has half a dozen distinct ones, each with its own character, price range, and set of considerations.

You can have open San Francisco Bay frontage with sweeping skyline views, a private dock on a calm man-made lagoon, a deep-water berth that fits a serious yacht, or a genuine floating home tucked into a tight-knit houseboat community. The lifestyle and the budget shift dramatically depending on which you choose.

This guide walks through the main waterfront communities — Belvedere and the Belvedere Lagoon, Paradise Cay in Tiburon, the Sausalito floating homes on Richardson Bay, Larkspur Marina, and Bel Marin Keys in Novato — so you can match the right kind of water to your goals and your price point.

Belvedere and the Belvedere Lagoon: Marin's Most Exclusive Address

Belvedere is the crown jewel of Marin waterfront and, frankly, the county's most expensive market. The community splits into two distinct experiences. Belvedere Island offers open Bay frontage with dramatic, unobstructed views of San Francisco, the Golden Gate, and the surrounding water — the kind of vistas that define the very top of the market.

Then there's the Belvedere Lagoon, a private, calm, man-made waterway where homes line the water with their own private docks. The lagoon is protected and serene, ideal for kayaks, paddleboards, and small boats right off your back patio. In 2025, the Lagoon saw 29 sales averaging roughly $6.3 million, or about $1,900 per square foot. Even undeveloped lots run $1.5 to $2 million and up.

Belvedere as a whole has ranged from about $3.9 million to $26.9 million, with an average near $6.3 million. This is a market where inventory is scarce and competition is real, so working with someone who knows the off-market landscape matters more here than almost anywhere else in the county.

Paradise Cay: Deep-Water Docks for Serious Boaters

If your idea of waterfront living centers on the boat, Paradise Cay in Tiburon may be the best fit in all of Marin. This community of roughly 225 homes was designed around the water — most homes sit directly on it, with private boat docks of 50 feet or more.

What sets Paradise Cay apart is depth and access. Many of the docks are deep-water with direct access to San Francisco Bay, and the community's yacht harbor offers berths accommodating boats up to 110 feet. For buyers who want to step off their back deck and onto a real cruising vessel, there's little else like it locally.

Pricing typically runs from about $1.9 million to $3 million and up, with a median over $3 million. You're paying for the combination of a single-family home, a private dock, and genuine deep-water access — a trio that's genuinely hard to replicate anywhere else in the North Bay.

Sausalito Floating Homes: A One-of-a-Kind Lifestyle (Read the Fine Print)

Sausalito's floating home community on Richardson Bay is one of the most distinctive places to live anywhere in the country. Roughly 400 to 425 floating homes are spread across docks with names locals know well — Liberty Dock, Issaquah Dock, South 40 Dock, Main Dock, and Yellow Ferry. The community is artistic, walkable, and deeply connected to the water.

Pricing spans a wide range. Entry-level floating homes start around $400,000 to $750,000; the middle of the market runs $750,000 to $1.2 million; and premium homes reach $1.2 to $2.8 million and beyond. For buyers priced out of conventional Marin waterfront, floating homes can be a genuine point of entry.

But here's the most important thing I tell every floating-home buyer: you typically own the floating structure, but not the water or the berth beneath it. You pay a monthly berth or slip lease — commonly around $1,000 to $1,500 per month — which usually covers water, garbage, sewage, parking, and common areas. Always confirm the exact fee with the specific marina, because it varies. Financing also works differently than for land-based homes, and the condition of the hull and the dock itself genuinely matter to value and lendability. This is a market where the right guidance pays for itself.

Larkspur Marina and Bel Marin Keys: Docks Without the Belvedere Price Tag

Not every waterfront home in Marin requires a multi-million-dollar budget, and two communities stand out for buyers who want a private dock at a more approachable price.

Larkspur Marina sits on Corte Madera Creek, right next to the beloved Larkspur Boardwalk. Many homes here come with their own private docks, and the location blends water access with easy proximity to downtown Larkspur's restaurants and the ferry. Prices generally run from about $2 million to $4 million — a meaningful step down from Belvedere while still offering true dock-front living.

Further north, Bel Marin Keys in Novato is a man-made keys and lagoon community with private docks that connect toward San Pablo Bay. With a median around $1.695 million as of late 2025, it's the most affordable waterfront-with-dock option in Marin. For boating families who want space, a dock, and value, Bel Marin Keys is often the smartest entry point into the lifestyle.

Matching the Right Waterfront to Your Goals and Budget

The best waterfront purchase isn't about chasing the highest-status address — it's about matching the water to how you actually want to live. If you want trophy views and the prestige of Marin's top market, Belvedere is the answer, with the Lagoon offering protected, dock-front calm and the Island delivering open-Bay drama.

If the boat is the point, Paradise Cay's deep-water docks and yacht-harbor access are hard to beat. If you love the idea of an artistic, water-immersed lifestyle and a lower entry price, Sausalito's floating homes are unlike anything else — just go in clear-eyed about berth leases and financing. And if you want a private dock without the top-tier price, Larkspur Marina and Bel Marin Keys deliver real value.

For context, conventional (non-floating) homes in Sausalito range widely — roughly $699,000 to $6 million — so even within a single town, the spread between water-view and true waterfront can be substantial. Note that all the figures here are approximate and point-in-time, reflecting roughly mid-2026; the waterfront market moves, and individual properties vary enormously based on dock, view, and condition.

How Taylor Lee Helps You Buy Waterfront in Marin

Buying on the water in Marin rewards local knowledge in a way few other purchases do. Dock permits, berth leases, deep-water access, hull condition, lagoon rules, and the realities of financing a floating home are all things that don't show up in a standard listing — and they can make or break a deal.

As an agent with Golden Gate Sotheby's International Realty, I help buyers navigate every one of Marin's waterfront markets, from Belvedere's off-market estates to Paradise Cay's deep-water docks to the floating homes of Sausalito. That means connecting you with the right inspectors and lenders for unconventional properties, surfacing listings before they hit the open market, and making sure you understand exactly what you own — and what you're leasing — before you commit.

If you're considering waterfront or water-view living anywhere in Marin County, let's talk about what you want from the water and which community fits. I'd be glad to be your guide.
