Pull up Sausalito listings this month and you'll see something that doesn't make sense at first glance. A two-bedroom floating home sits at well under a million dollars. A few blocks and a couple hundred vertical feet away, a hillside home with a bay view lists for three times that. Both show up under the same city name, the same median price calculation, the same "Sausalito real estate" search filter.
The median doesn't explain the gap. It papers over it.
Sausalito isn't one housing market wearing a single number. It's three distinct products, each with its own pricing logic, stapled together by a zip code. And the segment that looks like the bargain, the floating home community on Richardson Bay, just had its underlying cost structure rewritten by a state law that took effect this year. If you're comparing a sale price on a portal without knowing that, you're not seeing the real number.
Three Products, One Zip Code
Local market guides put Sausalito's overall median somewhere between $1.5 million and $2.1 million across all property types, with single-family detached homes averaging closer to $2.5 million. That range only holds together because it's blending three fundamentally different things.
| Segment | What you're buying | Primary cost driver |
|---|---|---|
| Hillside view estates | Land plus structure, often tiered lots with engineered foundations | Skyline and bay view exposure, foundation engineering for steep terrain |
| Downtown waterfront homes and condos | Smaller lots, walkable to Bridgeway shops and the ferry terminal | Land scarcity in a tight, low-elevation footprint |
| Floating homes | The structure only, moored to a leased berth | Berth lease terms, separate from the purchase price |
Hillside properties with unobstructed views of the San Francisco skyline consistently command the highest premiums in town, and that premium tracks to the engineering required to build and maintain foundations on steep terrain, not just square footage. Downtown waterfront homes trade smaller lots for walkability, and inventory there stays tight enough that well-maintained parcels draw real competition when they surface. Floating homes are the outlier. They can list for a fraction of the hillside median, and the reason isn't just size. It's that the sale price on a floating home doesn't include the ground it sits on, because there is no ground. You're buying a structure and separately leasing the water space beneath it.
The Payment That Doesn't Show Up in the Sale Price
Sausalito's floating home community sits along Richardson Bay, concentrated at Waldo Point Harbor and a handful of neighboring docks. Waldo Point alone holds 282 berths, and every one of them has been occupied continuously since the 1970s. Sales happen through ordinary real estate transactions, structure passes to a new owner, but the berth is a separate lease with the marina, and that lease is where the real monthly cost lives.
Marina rate sheets make the math concrete. Richardson Bay Marina posts a rate of $15.50 per linear foot per month, with a minimum berth size of 26 feet, which works out to roughly $403 a month before metered utilities. Clipper Yacht Harbor's published rates run $15 to $33 per foot depending on size and basin. On a typical 30 to 40 foot berth, that's a recurring cost of several hundred to well over a thousand dollars a month, on top of the purchase price, and it's a number that doesn't show up in most portal searches or price-per-square-foot comparisons.
That gap is exactly why a floating home's headline price can look like an entry point into Marin waterfront living while carrying a second, ongoing housing payment that a land-based comparison never has to account for.
Why the Berth Bill Just Changed
For years, Marin's floating home community, roughly 425 homes according to the Floating Homes Association, operated under a rent cap law written for a different problem. AB 252, passed in 2022, applied a uniform formula across Alameda, Contra Costa, and Marin counties after a wave of berth rent hikes elsewhere in the Bay Area put homeowners in a bind. One legislative analysis from that period described a floating home that fell out of escrow because the berth rent had become unaffordable to a buyer.
The one-size-fits-all approach didn't fit Marin, which has the overwhelming majority of the Bay Area's floating homes compared to just 42 in Alameda County and 11 in Contra Costa County. Marin's docks had historically run on long-term, CPI-only leases that predated AB 252, and the new law's rules on resetting rent at a home's sale made it harder for marina owners to fund capital work like dock repairs and utility upgrades. Some marinas responded by shifting from 10 or 20 year leases down to one-year terms and adding new fees to recover lost revenue, which made costs less predictable for homeowners in the exact way the original law was meant to prevent.
The fix is AB 754, authored by Assemblymember Damon Connolly, signed by the Governor in October 2025 and effective January 1, 2026, following two years of negotiation between the Floating Homes Association, marina owners, and Marin County officials. It caps annual berth rent increases to a CPI-based formula with a floor of 3 percent and a ceiling of 7.5 percent, and it requires marinas to return to long-term leases of 10 years or more rather than the shorter terms that had crept in. It also sets specific rules for how rent can be reset when a home changes hands, an "in-place transfer," including a certification process where the buyer confirms the sale price under penalty of perjury.
The law wasn't controversial locally. The Floating Homes Association surveyed residents across all six marinas, and more than 400 residents responded, a 67 percent response rate, with 93 percent voting in favor of the proposal before it went to Sacramento. That level of buy-in matters for a buyer today, because it means the rules governing your future berth costs were negotiated by the people who actually live under them, not imposed from outside.
What This Means If You're Comparing Numbers on a Portal
If a floating home's list price is pulling you toward Sausalito because it looks like the affordable way into the market, the purchase price is only half the picture. Before treating it as a bargain, you'd want to know:
- What is the current monthly berth rate, and is it locked into a long-term lease under the new 10-year framework, or still on a shorter term left over from before AB 754?
- Does the berth rent reset at sale, and has the seller documented the certification process the law now requires?
- Are there pending capital assessments for dock, piling, or seawall work? Some docks in the floating home community are mid-renovation on exactly that kind of infrastructure right now.
- Will your lender finance this specific dock and lease structure? Floating home financing runs through specialized lenders, not a standard conventional mortgage.
For hillside and downtown buyers, the equivalent homework runs the other direction. You're not pricing a berth lease, you're pricing land and view exposure, and the premium at the top of the market tracks almost entirely to unobstructed bay and skyline sightlines and the foundation engineering steep lots require. Two homes with the same square footage can sit worlds apart in price once you account for what the lot itself is doing for the view.
None of this makes one segment better than another. It means the median price you see on a portal is an average of three different bets, and the only way to know which bet you're actually making is to ask what's underneath the number.
A Few Straight Answers
Does AB 754 apply to floating homes purchased before 2026? The law's protections apply to rent increases occurring on or after July 1, 2025, and marinas had until the end of that calendar year to update existing leases to the new terms. If you already own a floating home, it's worth confirming with your marina whether your lease has been updated to reflect the 10-year, CPI-indexed structure the law now requires.
Is a floating home actually cheaper to own than a hillside or downtown home? It depends on what you're comparing. The purchase price is typically lower, but the berth lease is a real, ongoing cost that a land-based home doesn't carry. Run the total monthly number, purchase financing plus berth rent plus utilities, before comparing it to a land-based mortgage payment.
Can I finance a floating home the way I would a regular house? Not through a standard conventional mortgage in most cases. Floating homes are typically financed through lenders who specifically underwrite this property type and understand the lease structure involved.
Sausalito rewards buyers who understand which of its three markets they're actually shopping in.
