When a deed near San Bruno says lot and block, the Daly City plat map is where those numbers come from. This Daly City guide covers: where plats are filed, how a plat differs from a parcel map, and the details that matter to buyers.
Who keeps the Daly City plat map
For a subdivision near Colma, the deed or parcel record often names the subdivision and plat reference; bring that to the recorder's office or its online index.
The viewer San Mateo County publishes

On ground around San Bruno, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it.

Metes and bounds instead
Acreage around San Bruno outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.
Daly City and the county around it
Daly City is part of San Mateo County, California, and the county assessor maps its lots. For acreage around San Bruno, 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. Acreage past the town limits near Colma often answers to county rules, not municipal ones.
Limits of the parcel data
The acreage figure is an assessed number; just a licensed surveyor sets the real lines on land around Pacifica. In and around South San Francisco, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Legal descriptions in California
California uses the Public Land Survey System, so rural legal descriptions near San Bruno cite 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 Brisbane vary in size. Keep the legal description for land near San Bruno before you request a deed or survey.
Taking the map into the field
Most viewers work in a phone browser, useful out on a road near Pacifica, but coverage can be spotty out of town. A screenshot of the parcel near Millbrae with its ID keeps working without signal.
Getting your bearings
Redwood City is the county seat, home to the main records offices. You'll also find Colma, San Bruno, Brisbane, and South San Francisco, each with its own cluster of lots. Roughly 726,353 people live in San Mateo County (Census Bureau estimate, 2023) on some 449 square miles. Features like Don Edwards San Francisco Bay National Wildlife Refuge make handy reference points on the map near San Bruno.
Where the recorded documents are
When the details count, pull the recorded deed from the County Recorder; the parcel map near Colma only summarizes it. Around San Bruno, have ready the instrument number listed on the parcel record and the lookup takes minutes.
