Where the parcel data lives

For a parcel near Burlingame, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. If you're looking near Foster City, the parcel card typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
City limits and county records
Hillsborough is part of San Mateo County, California, so its parcels are on the county's map. In and around Burlingame, 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 San Bruno generally falls under county rules, not municipal ones.
Who the record really names
With a lot near San Mateo, the record lists the owner of record, sometimes a trust or LLC. "Estate of" on a record near Burlingame usually means title hasn't passed yet after a death, so the personal representative is the contact.
Who handles what
Recorded documents for a parcel near San Mateo sit in the index kept by the County Recorder, sometimes only in person. Zoning, permits and septic questions near Foster City are for the local planning and health departments, town or county, depending on location.
Limits of the parcel data
The acreage figure is a tax-roll number; only a licensed surveyor sets the real corners on land around Burlingame. For a home near San Bruno, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Proof of ownership
If the land is near Belmont, a viewer entry isn't legal proof; the recorded deed at the County Recorder is.
