The Buying Process in Corte Madera and Larkspur, California
Buying here runs through standard California residential real estate law and disclosure requirements, but two facts make this specific market genuinely different from a single-city waterfront town: Corte Madera and Larkspur are separate cities with separate building departments and permit processes, and any property near the Bay or Corte Madera Creek's tidal reach may also require review from the regional Bay Conservation and Development Commission (BCDC) on top of whichever city's own process applies. This page covers both the standard California mechanics and the local wrinkles a buyer should plan around.
Standard California Disclosure Requirements
California requires sellers of residential property to complete a Real Estate Transfer Disclosure Statement (TDS) covering known material facts about a property's condition, and a separate Natural Hazard Disclosure (NHD) statement identifying whether the property sits within specific state-mapped hazard zones -- flood, fire, seismic, and others. In this market, the NHD is a genuinely load-bearing document: it should reflect whether a specific Corte Madera or Larkspur parcel sits within FEMA's mapped Special Flood Hazard Area (zones AE or VE), within a mapped Fire Hazard Severity Zone, and within any state-identified Alquist-Priolo earthquake fault zone or seismic hazard zone. A buyer should read the NHD closely rather than treating it as routine paperwork, and should independently verify its findings against FEMA's Flood Map Service Center and Central Marin Fire Department's current Fire Hazard Severity Zone mapping rather than relying solely on the seller's disclosure.
Two Cities, Two Building Departments
Because Corte Madera and Larkspur are separately incorporated cities, any permit-dependent work on a property -- a remodel, an addition, a new fence near a flood-prone area, or work touching a hillside lot's defensible-space requirements -- runs through that specific city's own building and planning department, not a shared Twin Cities office. This differs from public safety, where both cities share the Central Marin Police Authority and Central Marin Fire Authority, and from K-8 schooling, where both feed the same Larkspur-Corte Madera School District. A buyer moving between a Corte Madera listing and a Larkspur listing during a search should expect genuinely separate permit timelines, fee schedules, and planning-department contacts, and should not assume familiarity with one city's process carries over to the other.
BCDC: A Real, Additional Layer for Water-Adjacent Property
Any new dock, fill, bulkhead, or substantial change in land, structure, or water use within 100 feet of San Francisco Bay or Corte Madera Creek's tidally influenced reach falls under the jurisdiction of the San Francisco Bay Conservation and Development Commission (BCDC), a regional state agency created by the McAteer-Petris Act in 1965 specifically to stop the unregulated bay fill that had shrunk San Francisco Bay's open water over prior decades. This is a real, legally required layer most inland California buyers never encounter, and it applies on top of whichever city's own building permit is separately required. A buyer planning any waterfront or creek-adjacent structural work -- not just a boat dock, but potentially a seawall, a deck extension, or significant landscaping fill near the shoreline band -- should confirm with BCDC directly whether a specific planned project requires its own permit, rather than assuming a standard city building permit alone is sufficient. See the Dock & Pier Guide and Waterway Living pages for the fuller permitting picture.
Financing and Flood Insurance Timing
For a property mapped in a FEMA Special Flood Hazard Area, a federally backed mortgage will generally require flood insurance as a closing condition -- a real, sometimes overlooked timeline item given how recently, and how seriously, this market's flood risk showed up in the January 2-3, 2026 Highway 101 event. A buyer under contract on a flood-zone property should start the flood-insurance quoting process early in escrow rather than waiting until just before closing, since obtaining a policy (particularly for a property with any history of flood claims) can take longer than a standard homeowners policy. Ask the lender directly, early in the process, whether flood insurance will be required for the specific property under contract.
Prop 13 Timing and the Assessor
Because California's Proposition 13 resets a property's assessed value to the purchase price at close of escrow, the exact closing date and recorded sale price directly determine a buyer's first property tax bill -- covered in full mechanical detail on the Property Tax page. A buyer should confirm with the Marin County Assessor's office, or a local title company, roughly when to expect the first supplemental tax bill reflecting the new assessed value, since it typically arrives separately from and later than a lender-collected escrow estimate.
