A San Mateo property search: start here
For rural ground near Hillsborough with no address, pan to it and select the outline.
Opening the official parcel viewer
Go first to the San Mateo County parcel viewer; it maps every assessed parcel in the county, Hillsborough included. For acreage around Foster City, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near San Carlos, a pop-up or side panel typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
San Mateo, CA: the basics
San Mateo sits in San Mateo County, California, and the county assessor maps its lots. For land near Burlingame, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the town limits out by Foster City usually answers to county rules, not municipal ones.
What the owner name means
If a company owns land near Foster City, the state business entity search usually lists a registered agent. "Estate of" on a record near Belmont often points to an open probate, so the personal representative is the contact.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so a fence near Millbrae often sits several feet off the line on screen. Closer to Burlingame, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Values and taxes
The record for a parcel near Burlingame often lists value and tax amounts; questions about value go to the County Assessor.
Confirming with the deed
Use the book and page or instrument number from the record near Burlingame so the lookup is fast; hire a title company before money changes hands.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Millbrae, though signal can drop in rural spots. A saved image of the lot near Burlingame and its lines is a good backup.
Who handles what
If the acreage or value on a parcel near San Carlos looks off are handled by the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Foster City go to planning, building or health offices, and the answer depends on jurisdiction.
Reaching an owner
A polite note sent to the tax-bill address works better than knocking unannounced about a tract near Foster City.
Getting your bearings
Redwood City holds the county offices, where most land records are kept.

Roughly 726,353 people call San Mateo County home (Census Bureau estimate, 2023) across about 449 square miles. Features like Don Edwards San Francisco Bay National Wildlife Refuge are easy to spot when you zoom out from Millbrae.
