If you're looking at a floating home on Richardson Bay right now, there's a question worth asking before you ask about square footage: is this sale going to count as an "in-place transfer"?
Most buyers never hear that phrase until it shows up in a marina's paperwork, usually after an offer is already in. It matters more than it used to, because as of this fall, the answer determines exactly how much your berth rent can jump the day you close. That's new. For decades, marina owners in Marin could reset rent on a change of ownership with almost no limit, and lenders priced that uncertainty into everything about the floating home market, from loan caps to interest rates to how many banks would even touch the collateral. A California law that took effect in stages between July 2025 and January 2026 rewrote that math. And in the same weeks this piece is being written, the last of the anchor-out boats that gave Richardson Bay its reputation for regulatory chaos are being cleared from the water under a deadline that lands October 15, 2026.
Two separate stories, same calendar, and neither one has fully worked its way into how the $550,000-to-$2.8-million spread across Sausalito's docks gets talked about. Here's what actually changed, and what it means if you're weighing a floating home against a hillside lot or a waterfront condo somewhere else in Marin.
The Rent Reset Everyone Warned You About
Floating home owners buy the structure but lease the berth, and until recently that lease was the single biggest source of financing risk in the whole category. A 2022 law, AB 252, put some limits on annual rent increases across the Bay Area's floating home marinas, but it left the reset-on-sale question loosely handled, and the results showed up in real transactions. Legislative analysis of that period cites a Bay Area marina where berth rents were being doubled, causing one home to fall out of escrow and two others to sit with no offers at all because the new rent made the numbers stop working.
That's the scenario lenders were underwriting against for every floating home loan they wrote, not just the ones that actually blew up. It's a large part of why financing in this category still runs through a narrow lane of specialty lenders, why most floating home loans in Sausalito cap out around $1 million regardless of the buyer's qualifications, and why down payments in the 20 to 25 percent range are standard rather than exceptional. The collateral was a home sitting on a lease that could reprice without warning.
What Changed on Marin's Docks, Specifically
Marin has 425 of the floating homes in the state, compared with 42 in Alameda County and 11 in Contra Costa, according to the legislative record supporting the county's own bill. A one-size-fits-all statewide rule was never going to fit a market this concentrated in one place, so Marin sponsored its own fix. Assembly Bill 754, authored by Assemblymember Damon Connolly and backed by the Marin County Board of Supervisors, passed the Assembly and Senate without a single "No" vote and was signed into law on October 10, 2025.
Here's what it actually does, effective retroactively to July 1, 2025 and running until it sunsets on January 1, 2038:
| Before AB 754 | Under AB 754 (Marin only) | |
|---|---|---|
| Annual berth rent increase | Fixed cap near 5%, regardless of inflation | CPI-indexed, floor of 3%, ceiling of 7.5%; any CPI reading above 5% is halved |
| Rent reset when a home sells ("in-place transfer") | No dedicated formula, exposure to steep jumps | Capped at the lower of 25% above the prior rent or 0.15% of the home's sale price |
| Reset if resold again within 5 years | Not addressed | Capped lower still, at 15% |
| Lease term | Many owners on 1-year terms | Marinas required to convert to 10-year-plus terms by the end of 2025 |
| Law expires | 2030 (statewide version) | 2038 (Marin-specific) |
There's a wrinkle worth flagging if you're doing diligence on a home that changed hands or saw a rent letter between July 2025 and January 2026. The bill includes a retroactive catch-up clause: if a marina raised rent above the new limit during that window, the rent on January 1, 2026 rolls back to the July 2025 rate plus whatever the maximum permissible increase would have been, but the marina owes nothing back for what was already collected. If you're buying a home where that six-month window is part of the rent history, it's worth asking your title or escrow contact to confirm which side of that line the current rate landed on.
The Anchor-Outs Leaving This Month Are Not Your Comp
Here's where a lot of buyer confusion starts. Search "Sausalito houseboat" and you'll eventually run into news about anchor-outs, the population that lived on boats anchored in open water off Richardson Bay, outside any marina lease, for decades. That's a different market entirely from the floating homes on Issaquah, Main, South Forty, East Pier, or the docks at Waldo Point Harbor, all of which sit on paid berths inside regulated marinas. But the two stories share a regulator, and the ending of one is worth understanding if you're buying into the other.
In 2021, the Richardson Bay Regional Agency settled with the San Francisco Bay Conservation and Development Commission after years of dispute over eelgrass damage from anchor chains scraping the bay floor. The agreement set a hard deadline: every illegally anchored vessel gone by October 15, 2026. The number of anchor-out boats has fallen from a 2016 peak of 240 to just two remaining in the authorized anchorage as of RBRA's April 2026 update, both individually cleared to stay through October 26 while their occupants finish transitioning into housing. Back in March 2024, RBRA had already towed the last illegally anchored floating home, a structure built strictly for living rather than moving under power, off the water. As harbormaster Jim Malcolm put it at the time, "we have no more floating homes" in that specific illegal category. The distinction mattered then and it matters now: the marina-berthed floating homes that make up the actual real estate market were never part of that removal.
What does close out this month is an eight-year regulatory dispute that hung over the entire bay's reputation, not just the anchorage. For lenders, insurers, and out-of-area buyers who couldn't easily tell an anchor-out from a marina-berthed home on paper, that ambiguity was one more reason to treat the whole category cautiously. It's disappearing on the same calendar as the rent-reset fix.
Comparing Your Options With the New Numbers in Hand
If you're weighing a floating home against a hillside property or a waterfront condo elsewhere in Marin, the traditional framing still holds in most respects. A hillside home gives you land ownership and no marina rules, but you're managing drainage, retaining walls, and permit history on your own. A condo trades exterior maintenance for shared governance and HOA dues. A floating home gives you the water itself, at a price point that can start well under $1 million, but comes with a structural financing ceiling near that same number, a marine survey requirement, and a hull that needs the kind of documentation a land appraiser never asks for.
What's different now is the risk that used to sit on top of all of that. The unpredictable rent reset and the reputational fog around the bay's regulatory status were two separate discounts buyers and lenders were pricing in, often without naming them specifically. Both are being closed out on paper this fall. That doesn't change what a marine survey costs or what a chattel loan looks like next to a conventional mortgage, but it does change the multi-year carrying-cost conversation in a way the sale price alone won't show you.
Before you write an offer, ask for three things: the berth rent as of July 1, 2025, confirmation of whether the lease has been converted to a 10-year-plus term, and whether your purchase will be treated as an in-place transfer, along with the marina's math on what the new initial rate will be under the 25 percent or 0.15 percent cap. Every one of those answers is now governed by statute instead of marina discretion, which is the actual news here.
A Few Questions Worth Asking Directly
Does AB 754 cap the sale price of the floating home itself? No. It caps what the marina can charge for the berth lease. The structure's sale price is still set by the private market, same as any home.
Does this apply anywhere else in Marin, or just Richardson Bay? The law applies to any floating home marina located in Marin County, so it isn't limited to Sausalito's docks specifically, though that's where the overwhelming majority of the county's floating homes are.
Does the anchor-out removal affect parking, access, or insurance for the marina docks? Not directly. The anchor-out population was never berthed in the marinas, so the physical removal doesn't change dock access. What it does close out is the years-long enforcement dispute between RBRA and BCDC that shaped how outside parties, including some lenders, viewed the bay as a whole.
Floating homes have always required a different kind of diligence than a house on a lot, and that hasn't changed. What has changed is which questions actually have firm answers now.
