Santa Clara County Clerk-Recorder - repository of early survey plats

The Santa Clara County Clerk-Recorder's Office holds recorded maps, survey plats, and land records for San Jose, including Spanish and Mexican-era land grant documents and 19th-century subdivision plats. These official records have been used to establish legal property boundaries and trace historical surveys across the city. Researchers and surveyors consult the Recorder's archives to access original plats and field notes for historical boundary determinations.
