The house at 125 Belvedere had a private pier, a boat dock, and a 51-foot motor yacht parked at Pier 39 in San Francisco. All of it went up for auction together this summer, staged as one waterfront package with a bargain starting price meant to pull buyers off the sidelines. Then, days before bidding was set to open, a buyer stepped in and closed at close to $17 million, according to a September 2026 SF Standard report. He kept the house. He walked away from the yacht.
The Standard reported that the buyer wasn't a boater. He wanted the views, the exclusivity, the waterfront address, not the vessel that came bundled with it. It's a small detail, but it says something true about how Belvedere waterfront deals actually work. What's included with a bay-front or lagoon-front property here is never assumed. It's itemized, negotiated, and in some cases governed by paperwork that has nothing to do with the sale price.
The Dock Is a Separate Question From the House
Along Beach Road, West Shore Road, and around Belvedere Lagoon, water access comes in different legal shapes depending on the parcel.
None of that shows up in a walkthrough. It shows up in the parcel paperwork. A buyer who assumes a dock transfers because it's sitting right there in the yard is skipping the paperwork that actually answers the question.
The Lagoon Adds a Membership You Don't Choose
Buy on Belvedere Lagoon specifically, and there's another layer on top of the deed. The lagoon is private and artificial, managed by the Belvedere Lagoon Property Owners Association.
Current dues run $570 per quarter with no increase set for 2026, but members also approved a one-time $600 special assessment in 2025 to repair bulkhead sections and maintenance equipment. That assessment is a useful reminder on its own: lagoon infrastructure, the bulkheads and shoreline retaining elements that keep the water where it belongs, needs periodic capital work, and owners fund it collectively.
There's also a use restriction worth knowing before anyone pictures lagoon life as identical to open-bay living.
Some Docks Answer to the City, Not Just the Buyer
Deed rights and HOA membership cover most of the picture, but a portion of Belvedere's waterfront sits under a third kind of arrangement: a lease from the city itself, with an actual expiration date attached.
That structure played out in a Belvedere Planning Commission case at 310 and 312 Beach Road in July 2026. The owners, including applicant Mark Conroe, asked to add a 270-square-foot dock expansion, two boat lifts, and kayak racks. A Citizen Portal report said the commission approved the dock enlargement and the lifts. It denied a proposed equipment shed.
Staff noted the existing dock lease for that property expires June 30, 2039. That's not a hypothetical decades out. It's a fixed date already on file with the city, and it's the kind of detail a buyer only finds by asking, since it won't appear on a comparable sales sheet. The Belvedere Municipal Code spells out what counts as a dock under city rules, and it's worth reading directly rather than assuming a private easement covers ground the city actually leases.
The Seawall Project Planned Along the Same Corridor
There's a second, larger process moving through the same corridor right now, and it has nothing to do with any single dock. The City of Belvedere is working through the Beach Road Stabilization Project, a levee and seawall reinforcement meant to protect San Rafael Avenue and Beach Road, the two roads that also happen to be the only connectors between Belvedere and the rest of the Tiburon Peninsula.
In April 2026, the city council awarded the construction contract to Gordon N. Ball Inc. for $3.51 million, after closing a $310,000 funding gap with reallocated capital funds. But the award didn't clear the project to start. A March 2026 Citizen Portal report said construction depends on permits from the Bay Conservation and Development Commission and the Army Corps of Engineers, on PG&E completing utility relocation work along Beach Road, and on securing temporary construction easements from three private property owners whose land the work has to cross.
"So first of all, permitting. We're waiting for a BCDC permit," public works director Tony Boyd said at the project subcommittee, according to Citizen Portal. A later subcommittee briefing in May added that the Army Corps and NOAA were requesting a benthic and shoreline eelgrass survey before signing off, adding another dependency to an already tight schedule. The in-water portion of the work only has a June-to-October window each year. If permitting or the easements slip much further, staff have said the project could push into 2027.
None of this touches ownership of any individual home. It does mean that anyone buying along Beach Road, San Rafael Avenue, or West Shore Road right now is buying next to an active infrastructure project with a permitting timeline still in motion. That's worth a phone call to the city before assuming quiet enjoyment of the waterfront strip is guaranteed on any particular summer.
What to Confirm Before You Write an Offer
A few questions answer most of what a purchase contract won't:
- Does the title report or deed show a recorded dock or water easement, and does it match what's physically there.
- If the property fronts the lagoon, are BLPOA dues current, and is there a pending or recent special assessment.
- Is the dock covered by a private easement or a lease from the city, and if it's a city lease, when does it expire.
- Has the property, or a close neighbor, gone through Planning Commission review for shoreline work recently, and what conditions came attached.
- If the parcel sits along Beach Road, San Rafael Avenue, or West Shore Road, what's the current status of the city's seawall permitting and construction schedule.
A Couple of Questions Worth Settling Early
What should a buyer check about a Belvedere Lagoon dock? Check the parcel paperwork for information about dock or water access.
Will the Beach Road seawall project affect a purchase happening now? It could affect timing rather than the transaction itself. The project is still working through BCDC and Army Corps permitting as of 2026, with a construction window tied to easements from three private owners. Anyone buying along that stretch should ask the city directly for the current permit status before assuming a fixed construction calendar.
Waterfront paperwork in Belvedere rewards patience more than speed. If you're evaluating a specific dock, lagoon membership, or a parcel along the seawall corridor, Daniel Nebenzahl can help you pull the right documents before you write the offer, not after.
