What exactly are you selling when a Paradise Cay listing includes a private dock? Most sellers assume the answer is obvious: the dock comes with the house, the way a fireplace or a finished basement does. It shows up in the photos, it adds to the asking price, and it closes when the house closes.
It doesn't always work that way. In this pocket of the Tiburon peninsula, the dock can carry its own paper trail, its own tax history, and its own maintenance calendar, one that doesn't run on the same schedule as your escrow. A seller who treats the dock as a fixed feature of the property, rather than a second asset with its own due diligence track, is the one who gets a title question or a buyer financing condition in week five of a thirty-day close, right when there's no time left to fix it cleanly.
The House Closes On One Clock. The Dock Runs On Another.
Paradise Cay is a small waterfront enclave on the bay side of the peninsula, built in the 1960s on filled tidelands and developed by the Moseley family, whose descendants, including 1998 Olympic gold medalist Jonny Moseley, still live in the community many locals call "Moseleyville." That land-use history isn't trivia. Because the community sits on filled bay land with private docks tied into shared waterways, almost everything below the waterline answers to a different set of rules than the house above it.
The home inspection covers the house. The dock, the channel it sits on, and the shared waterway leading out to Richardson Bay answer to the Town of Tiburon, the U.S. Army Corps of Engineers, the San Francisco Bay Conservation and Development Commission, and a special county tax district. None of those bodies care about your escrow deadline. That mismatch is the actual thesis here: a Paradise Cay sale is really two transactions running in parallel, a house sale and a waterway-access sale, and most purchase agreements are written as if there's only one.
What "Deeded" Actually Means Here
The first question a buyer's agent or title company should ask, and the first one a seller should be ready to answer before it's asked, is whether the dock is deeded to the parcel or governed by a separate agreement. This isn't a formality. It determines what actually transfers at closing.
- A deeded dock is legally part of the property and shows up in the vesting deed and the preliminary title report.
- A dock under a separate agreement, whether a license, an easement, or a shared-use arrangement with a neighboring parcel, may require its own transfer paperwork, and in some cases isn't guaranteed to convey automatically with the sale.
Title companies won't always flag this clearly on their own. A preliminary title report lists exceptions, including easements, but it's up to the buyer, the seller, or their agents to actually pull the underlying recorded documents and read what they say about dock use, maintenance responsibility, and transferability. If that review happens for the first time during a thirty-day escrow, a seller with an unclear dock title has almost no room to negotiate a fix. Doing that homework before listing, not after an offer arrives, is what keeps a Paradise Cay sale on schedule.
The Tax Line Nobody Explains Until the Buyer's Lender Asks
Most of the Tiburon peninsula carries no Mello-Roos community facilities district tax, which is one reason Paradise Cay's line item catches buyers off guard. Paradise Cay sits inside County Service Area No. 29, a special district the Marin County Board of Supervisors created under Resolution 92-04 specifically to fund maintenance dredging of the community's canals and waterways. Property owners inside CSA 29 pay a special tax or assessment, collected on the annual county tax bill, that a buyer moving from elsewhere on the peninsula won't have seen before.
That distinction matters at two points in a transaction. First, it needs to be disclosed clearly, since it's easy for a buyer to mistake it for a standard HOA fee rather than a county-levied tax tied to a specific waterway maintenance program. Second, a buyer's lender may ask questions about it during underwriting that a standard property tax line doesn't usually trigger. Sellers who can hand over the county's own CSA 29 documentation, including budget history and past assessment notices, close that question quickly instead of leaving it to guesswork mid-escrow.
The Dredge Cycle Is a Clock, Not a Formality
Here's the detail that separates a generic waterfront listing from one backed by real local knowledge: the channels aren't naturally navigable forever. Silt and mud settle into Paradise Cay's canals over time, and CSA 29 performs maintenance dredging on a recurring cycle, roughly every four to five years, to keep the waterways usable for the boats the community was built around.
The most recent maintenance dredge was scheduled for 2024, covering the interior waterways and the entry channels leading out to the bay. County environmental filings describe the target depths in specific terms, calling for the project to "dredge to minus seven in the Paradise Cay waterways and to minus eight in the entry channels." That's not an abstract permitting detail. It's the actual depth a boat owner can expect at low tide until sediment builds back up and the cycle repeats.
If the last dredge ran in 2024 and the cycle holds at four to five years, the next window likely falls somewhere between 2028 and 2029. That has two practical implications depending on which side of the transaction you're on. A buyer evaluating a property today is buying into a channel that's a couple of years past its last full maintenance cycle, which is worth confirming against the seller's most recent channel depth information before assuming a large vessel will clear at low tide. A seller listing a home now should have that dredge history on hand, because "when was this channel last dredged" is a question serious boat-owning buyers will ask, and "I don't know" reads very differently than a documented answer.
The dredging itself also isn't a simple maintenance call. Because the work happens in San Francisco Bay, it requires review and permitting from both the Bay Conservation and Development Commission and the Army Corps of Engineers, typically issued as multi-year permits that CSA 29 operates under rather than applying for fresh each time. That's part of why the timing tends to hold to a predictable cycle rather than happening whenever a resident wants it.
The Permit You Don't Expect: Modifying the Dock Itself
Even routine dock work in Tiburon runs through a permitting process that surprises buyers used to less regulated markets. The Town of Tiburon requires design review and a building permit for guard railings at waterfront bulkheads, fixed piers, and fixed gangways, on top of whatever BCDC and Army Corps approvals apply to the work itself. A buyer planning to replace a gangway or add railing to an aging dock should budget for that municipal layer, not just the marine contractor's estimate. A seller who has already been through that process, and can hand over the permits, saves the next owner a step that otherwise adds weeks to any post-purchase dock work.
What This Means If You're Listing This Year
None of this is a reason to avoid Paradise Cay as a seller or a buyer. It's a reason to sequence the paperwork before the offer arrives instead of after. Before listing a dock-equipped home here, pull the recorded documents on the dock itself, gather the CSA 29 tax and assessment history, confirm the most recent dredge date and depth for your specific channel segment, and collect any existing BCDC, Army Corps, or Town of Tiburon permits tied to dock work that's already been done.
A staging consultation or a fresh coat of paint won't touch any of this. The prep that actually protects a Paradise Cay sale happens in a file folder of recorded documents and county correspondence, gathered weeks before the first showing. That's the kind of groundwork that keeps a waterfront closing on its original timeline instead of extending it by a title question nobody saw coming.
FAQ
Does every home in Paradise Cay have a private dock? Most do, since the community was built around direct water access, but dock size, depth, and legal status vary by parcel. Buyers should confirm dock specifics for each property rather than assuming a standard configuration.
Is the CSA 29 tax the same as an HOA fee? No. It's a special tax levied by the county through a service area created by the Board of Supervisors, collected on the annual property tax bill, and used specifically for canal and waterway maintenance dredging rather than general community upkeep.
Can a buyer confirm channel depth before making an offer? Yes, by requesting the most recent pre-dredge or post-dredge condition survey from Marin County Public Works, which maintains records for CSA 29 alongside the district's dredging permits and budget history.
