Planning a hunt near Corte Madera? The Marin County hunting map is really two maps: where public access exists, and who owns everything else. Covered here for Marin County: where public hunting land is mapped, using the parcel viewer for boundaries, and getting landowner permission the right way.
Building your Marin County hunting map
For a parcel near Novato, start with California Department of Fish and Wildlife for public areas, along with seasons and regulations.
The viewer Marin County publishes
Property in and around Corte Madera can be looked up on the Marin County parcel viewer, which opens without registering. When a rural tract has no street number, follow US Route 101 on the aerial and click the parcel itself, which applies near San Pablo Bay as much as anywhere. If you're looking near San Rafael, write down the parcel ID while you have it open; every clerk in the county will want it.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Corte Madera, but coverage can be spotty out of town. A screenshot of the parcel near Novato with its ID helps when you meet an owner or agent.
Getting answers from the right desk
Questions about value or the owner field for land near Richardson Bay belong with the County Assessor, the office behind the parcel record. Questions about what you can build around Corte Madera go to planning, building or health offices, town or county, depending on location.
Reading the legal description
California uses the Public Land Survey System, which means a tract near Novato is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Mill Valley can be irregular. Write down the legal description for the tract near Corte Madera for any title or survey request.
Parcel lines for hunters
Parcel lines are approximate, so don't treat them as survey-grade near San Pablo Bay; paint or posted signs on the ground matter too.
Recorded documents worth pulling
Out toward San Rafael, the map is an index, not the title: recorded deeds, plats and easements for parcels in the county are kept by the County Recorder. Long-held tracts near Corte Madera may sit on several deeds, so a title company earns its fee if money is changing hands.
Good habits afield
Respect livestock and crops around Novato, and carry the owner's contact info; it keeps permission coming back.
Contacting owners
On ground around San Rafael, offer details: who you are, when you'd hunt and how to reach you, and respect a no.
Before you go
Seasons, licenses and trespass laws are set by the state, and trespass rules differ by state wherever you hunt near San Francisco Bay.
Limits of the parcel data
With a lot near Belvedere, the acreage figure is a tax-roll number; only a licensed surveyor can set the real corners on the ground. If you're looking near Corte Madera, records update in batches, so a deed recorded last month can take weeks to appear.
Scouting from the aerial
Switch to aerial imagery near San Rafael, look for field edges, creek bottoms and timber lines; match each spot to its parcel.
Marin County in a few facts
San Rafael is the county seat, home to the main records offices. Other places on the map include Belvedere, Corte Madera, Fairfax, and Larkspur, where town lots give way to larger tracts. Around 254,407 people live in Marin County (Census Bureau estimate, 2023) spread over about 520 square miles.

Neighboring parcel maps
Marin County borders Contra Costa County, San Francisco County, Solano County, and Sonoma County, and each of those keeps its own parcel map. A tract near the line by Larkspur can show up in two county records, so open the neighboring map before you assume the acreage. For a tract near Belvedere, the Platbookmapper state page links each bordering county map for California.
