When a listing near San Bruno mentions a lot number, you'll need the Brisbane plat map to make sense of it. Covered here for Brisbane: where to request a copy, plat versus tax map, and the details that matter to buyers.
The Brisbane plat map: start here
For a subdivision near Millbrae, look for the plat book reference on the parcel record; use it to request a copy.
The viewer San Mateo County publishes
Your first stop is the San Mateo County parcel viewer; it includes each assessed parcel in the county, Daly City included. For land near San Bruno, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. Near South San Francisco, the record panel normally shows the owner of record, assessed acreage, the parcel number and often a sale date.
Metes and bounds instead
Rural land near Colma that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
Brisbane and the county around it
Brisbane sits in San Mateo County, California, so its parcels are on the county's map. Local government in Brisbane handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the city limits toward San Bruno usually answers to county rules rather than the town's.
Offices that can help
If the acreage or value on a parcel near Daly City looks off go to the County Assessor, since that office keeps the assessment data. Questions about what you can build around Daly City are for the local planning and health departments, town or county, depending on location.
The paper trail behind a parcel
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Burlingame sit with the County Recorder. Older tracts around San Bruno can go back through several deeds, and a title company can sort it out if money is changing hands.
How land is described here
California is laid out under the Public Land Survey System, so rural legal descriptions near Daly City cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near South San Francisco odd-sized. Keep the legal description for land near Daly City for any title or survey request.
Amended plats
Lots near Daly City can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near San Bruno show up in the records too.
Plat map vs. parcel map
If the tax map and plat differ near Colma, trust the recorded documents over the GIS layer.
Land on the county line
For property near Millbrae, San Mateo County borders Alameda County, San Francisco County, Santa Clara County, and Santa Cruz County, and each of those keeps its own parcel map. Ground near Burlingame that runs to the line can be split across two assessors' files, so look at the neighboring map as well. On ground around San Bruno, our state page lists every bordering county map across California.
What the map can't tell you
Tax maps are drawn for assessment, not measured on the ground, so a fence near Colma often sits a few yards off the line on screen. For property near Burlingame, records update in batches, so a deed recorded last month can take weeks to appear.
What a plat shows
Recorded easements around San Bruno limit where you can build or fence; read the notes on the sheet.
Requesting the plat
For a parcel near Colma, many recorder offices offer an online index, while others require a visit or a request; small fees are common.
Places you'll see on the map
For a tract near Colma, redwood City holds the county offices, where most land records are kept. Smaller places on the map include South San Francisco, Colma, San Bruno, and Daly City, where town lots give way to larger tracts. If the land is near Daly City, about 726,353 people call San Mateo County home (Census estimate, 2023) across about 449 square miles. Features like Don Edwards San Francisco Bay National Wildlife Refuge make handy reference points on the map near Colma.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
