The listing photos show a private dock, two slips, and a kayak launch. The agent calls it “deeded waterfront.” Two weeks after close, a neighbor mentions the dock was rebuilt without a permit in 2019. Now you own an enforcement problem.
This is not hypothetical. On the Tiburon peninsula, a meaningful share of waterfront structures predate current jurisdiction, and quite a few were altered in ways that never made it onto the county record.
Key Takeaways
- A dock shown in photos does not automatically transfer with the property or its permits.
- Riparian, littoral, and tideland rights are three different legal instruments and most listings conflate them.
- BCDC and the Army Corps of Engineers both touch Tiburon waterfront, with overlapping but distinct authority.
- A proper pre-offer document pull costs under $500 and saves six-figure remediation bills.
- Insurance carriers in 2026 are increasingly declining coverage on unpermitted overwater structures.
Why a Dock in the Photo Is Not a Dock on the Title
A physical dock is a structure. Dock rights are a bundle of legal claims: the right to moor, to occupy tidelands, to rebuild after storm damage, and to transfer those rights to a future owner. These claims do not always travel together, and they do not always travel with the fee title to the upland parcel.
Common failure modes in Tiburon escrows:
- Dock was rebuilt post-1970 without a BCDC permit and has no grandfather status.
- Dock sits on a State Lands tideland lease that requires re-approval on transfer.
- Dock is shared with a neighbor under an unrecorded handshake.
- Dock is legal but capped at one vessel under the original permit.
A working marin real estate broker familiar with Tiburon waterfront will insist each of these be disproven before contingencies remove.
Riparian, Littoral, and Tideland: What Actually Transfers
The language is old and the distinctions are sharp.
- Riparian rights attach to parcels abutting flowing water (creeks, rivers). In Tiburon, this applies to a small subset of parcels near seasonal drainages.
- Littoral rights attach to parcels abutting tidal water (San Francisco Bay, Richardson Bay, Raccoon Strait). Most Tiburon waterfront parcels are littoral, not riparian.
- Tideland rights are a separate interest, often held by the State Lands Commission or granted to municipalities. If your dock extends past mean high water, you are almost certainly on tideland, not on your own parcel.
The practical implication: even a seller with clean fee title to the upland parcel may have no legal right to extend a structure onto tideland. That extension requires a permit, a lease, or both.
BCDC and Army Corps Jurisdiction in Plain English
Two agencies matter most on the Tiburon waterfront.
- BCDC (San Francisco Bay Conservation and Development Commission): jurisdiction runs 100 feet inland from the high tide line. Any fill, pile driving, or structural modification needs a permit. Replacement-in-kind has narrow exceptions and is not automatic.
- U.S. Army Corps of Engineers: jurisdiction over navigable waters under Section 10. Most overwater structures need a Nationwide or Individual Permit.
The Town of Tiburon Building Division and Belvedere Building Department also issue separate permits for the upland connection, gangway, and electrical. A legal dock typically has four to six approvals. A problem dock has one or none.
The Pre-Offer Document Pull
Here is the paper trail a serious buyer should assemble before signing.
| Document | Source | What you are checking |
|---|---|---|
| BCDC permit history | BCDC public file | Original permit plus amendments |
| Army Corps authorization | Corps SF District | Nationwide or Individual Permit |
| Tideland lease | State Lands Commission | Term, transferability, status |
| Municipal permits | Tiburon / Belvedere | Upland, electrical, gangway |
| Title easement schedule | Preliminary title report | Shared-use or access easements |
| Mean-high-water survey | Licensed surveyor | Footprint inside permitted lines |
Your escrow officer cannot assemble this stack. Your agent should, and the cost is typically under $500. A marin realtor who handles waterfront regularly will already have preferred vendors for surveys and permit runners.
Red Flags That Should Slow the Deal Down
Walk slower if any of these surface.
- Listing says “deeded dock” but the preliminary title report has no recorded easement.
- BCDC file shows an original permit but no amendment for an obvious rebuild visible in historical aerials.
- Disclosures mention “dock repaired 2017” with no permit number attached.
- Neighbors reference a “shared slip agreement” nobody can produce.
- Insurance carrier declines to bind coverage on the overwater structure.
A sample escrow addendum clause worth considering:
Buyer’s obligations are contingent upon seller producing, within 10 days, copies of all BCDC permits, Army Corps authorizations, tideland leases, and municipal building permits for the existing dock, gangway, and any overwater structures, together with a licensed surveyor’s certification that the structures lie within permitted footprints.
Sellers with clean paperwork produce it in 48 hours. Sellers who take 10 days and still cannot produce it have just told you something important.
Frequently Asked Questions
Does the dock automatically convey with the sale?
The physical structure conveys as a fixture. The legal right to use it, maintain it, and rebuild it only conveys if the underlying permits, leases, and easements are transferable. Teams like Outpost Real Estate that source a meaningful share of Tiburon waterfront trades off-market tend to have the permit stacks pre-assembled, which is how transferability gets confirmed in writing before contingencies are removed.
What is BCDC and why does it matter in Tiburon?
BCDC is the Bay Conservation and Development Commission, a state agency with jurisdiction over Bay shoreline within 100 feet of high tide. Nearly every Tiburon waterfront parcel touches BCDC jurisdiction. Dock work since 1965 generally required a BCDC permit, and enforcement actions can require removal.
Can I rebuild an existing Tiburon dock if it is storm damaged?
Sometimes, under narrow replacement-in-kind allowances. If the rebuild changes size, pile count, or footprint, it is treated as new construction and requires fresh permits. Many buyers assume repair rights are automatic; they are not, and scope creep during repairs is the most common source of BCDC enforcement letters.
How long does a new dock permit typically take in Tiburon?
Plan for 12 to 24 months for a clean application, longer if neighbors object or eelgrass surveys are required. Because of that timeline, a parcel with existing permitted dock infrastructure commands a 15 to 25 percent premium over a dry-side parcel with dock potential at similar view quality.
The Quiet Cost of Skipping the Paper Trail
Enforcement on unpermitted Tiburon waterfront is slow but real. A neighbor complaint, an aerial review, a BCDC site visit, and suddenly the new owner is answering a notice of violation that should have surfaced before escrow closed. Remediation orders here have landed between $40,000 for a gangway rework and well over $300,000 for a full dock removal and rebuild. The buyers who avoid this are not lucky; they are methodical. They pull permits before they pull the trigger.
