San Jose California Plat Maps
San Jose, California plat maps are the recorded subdivision sheets for that place. They are not a survey.

The search
People type "San Jose California Plat Maps" when they want the recorded plat, the lot-and-block sheet, or the parcel map for land in San Jose, California. Santa Clara County is the plat book for San Jose.
Where the sheet is kept
Start with Santa Clara County. A city street map, a zoning map, and a pin on an aerial photo are not the plat. The recorded plat is the subdivision drawing in the land records. The public GIS layer is the assessor parcel map.
Open the directory
Use the California page on Platbookmapper and find Santa Clara County. Match the parcel ID from the tax bill before you trust an address pin.
What the search will not do
It will not draw your lot line. Parcel lines on a public map are an assessment layer, not a boundary survey. When the corner itself is the question, you need the recorded plat and, if the line is in dispute, a licensed surveyor.
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.
