Ahead of any building plan near Novato, check the Fairfax zoning map before anything else: a district label decides setbacks, lot size and uses. In this town guide: who controls zoning for a given parcel, matching a lot to its zoning district, and what to ask the planning staff, at least around Belvedere.
The Fairfax zoning map: start here
Within municipal limits, the local government adopts its own zoning map, so property inside Fairfax is governed there. Past the city line, around Belvedere, county rules apply where they exist; the county planning or zoning office can confirm. The quickest way to tell which applies: ask whether the parcel near Larkspur is inside the boundary.
Getting to the right map
Your first stop is the Marin County parcel viewer; it includes every tax parcel in the county, Belvedere included. On ground around Corte Madera, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near San Rafael, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Reading the legal description
California follows the Public Land Survey System, so rural legal descriptions near Novato cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Corte Madera odd-sized. Copy the legal description from the record for the parcel near Novato before you request a deed or survey.
What to ask before you buy
When you call about land near Mill Valley, give the parcel number and your intended use; ask what's allowed by right and what needs a permit. Ask whether a parcel near Mill Valley meets current minimum size, since some older splits don't.
City limits and county records
Fairfax sits in Marin County, California, so its parcels are on the county's map. For a tract near Corte Madera, 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 town limits toward Belvedere generally follows county rules, not municipal ones.
Before you lean on the lines
The acreage figure is an estimate; only a licensed surveyor establishes the real corners for a parcel near Belvedere. Out toward San Rafael, records update in batches, so a deed recorded last month might lag behind.
When a parcel crosses a boundary
Marin County borders Contra Costa County, San Francisco County, Solano County, and Sonoma County, and each of those keeps its own parcel map. Acreage along the edge near Novato can be split in two county records, so look at the neighboring map too. Around Corte Madera, the Platbookmapper state page links every neighboring county map for California.
Finding a parcel's zoning district
Some planning offices post the Fairfax zoning map as a PDF; staff can confirm the district if you send the parcel ID. For a tract near Belvedere, district codes like R-1, C-2 or A-1 point to a table of rules in the ordinance; don't assume a code means the same thing everywhere.

Features like San Pablo Bay, San Francisco Bay, and Golden Gate National Recreation Area are easy to spot when you zoom out from Novato.
