Redwood City, CA: the basics
Redwood City is part of San Mateo County, California, so its parcels are on the county's map. As the county seat, Redwood City hosts the courthouse, so deeds and plats are filed in town. For property near San Carlos, City or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits out by Atherton generally follows county rules, not municipal ones.
Places you'll see on the map
Redwood City holds the county offices, which is where the courthouse records live. You'll also find San Carlos, Foster City, Atherton, and Menlo Park, each with its own cluster of lots. Roughly 726,353 people call San Mateo County home (Census Bureau estimate, 2023) across some 449 square miles. Features like Don Edwards San Francisco Bay National Wildlife Refuge are easy to spot when you zoom out from Atherton.
A word on accuracy
Parcel lines are drawn for taxes, not measured on the ground, so a fence near Belmont may sit some distance off the line on screen. For land near Atherton, records update in batches, so a deed recorded last month might lag behind.
Looking around the parcel

What the owner name means
For an LLC on a parcel near Menlo Park, the state business entity search usually lists a registered agent. "Estate of" on a record near Atherton usually means title hasn't passed yet after a death, and the executor handles questions.
Neighboring parcel maps

Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements covering ground around Atherton are filed with the County Recorder. Inherited tracts around Menlo Park may go back through many deeds, and a title company is worth hiring before a purchase.
Proof of ownership
Bring the document number shown for the parcel near Atherton to find the deed quickly; a title search is wise before any purchase.
Sections, lots and bearings
California follows the Public Land Survey System, so rural legal descriptions near Belmont cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Belmont can be irregular. Keep the legal description for land near Menlo Park for any title or survey request.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Atherton, though signal can drop in rural spots. A screenshot of the parcel near Menlo Park with its ID keeps working without signal.

Getting answers from the right desk
Anything recorded against property around Foster City are with the County Recorder, sometimes only in person. Building or septic questions for a lot near Menlo Park are for the local planning and health departments, depending on whether the land is inside town limits.
