For a parcel in or near Novato, the Novato GIS map shows lines, owner names and parcel numbers. This Novato guide covers: where that map lives, how to search it, and what to double-check with records.
Where the Novato GIS map lives
In and around San Rafael, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Where the parcel data lives
Go first to the Marin County parcel viewer; it includes each assessed parcel around Larkspur and San Rafael. If the land is near Corte Madera, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a tract near Mill Valley, a pop-up or side panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Where Novato fits in
Novato lies within Marin County, California, and the county assessor maps its lots. If the land is near Ross, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Lots just outside the city limits toward Corte Madera generally answers to county rules rather than the town's.
Offices that can help
For assessment questions about property around Corte Madera belong with the County Assessor, the office behind the parcel record. Questions about what you can build around San Rafael go to planning, building or health offices, and the answer depends on jurisdiction.
Sections, lots and bearings
California uses the Public Land Survey System, which means a tract near Mill Valley is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Ross vary in size. Copy the legal description from the record for the parcel near Ross when you talk to a surveyor.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Ross, so load it before you lose signal. A screenshot of the parcel near San Anselmo with its ID is a good backup.

Before you lean on the lines
The acreage figure is an estimate; only a licensed surveyor establishes the real corners for a parcel near Corte Madera. For a parcel near Larkspur, records update in batches, so a deed recorded last month might lag behind.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, plats and easements for land near Mill Valley sit with the County Recorder. Inherited tracts near Larkspur may trace back through several deeds, and a title company can sort it out before a purchase.
Searching the map
For a house in Novato, search the street address; for owner searches, try last name first. On ground around Mill Valley, searching by parcel number never misses, and you'll find it on tax statements.
