A San Benito County plat book is the township-by-township atlas farmers, hunters and land buyers around Aromas have kept in the truck for generations. This guide covers finding a printed edition for San Benito County, California, and using the free parcel map in the meantime.
How to use the San Benito County plat book
Think of the San Benito County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Hollister. Don't confuse it with a subdivision plat on file for lots in Hollister; that recorded plat is a legal document, while the atlas is a reference.
Step one: the free San Benito County viewer
San Benito County publishes its parcels on the San Benito County ArcGIS parcel map, which runs on an Esri ArcGIS web map, free to use for a lot in San Juan Bautista or a tract close to Aromas. Most people find their San Benito County tract fastest by searching an address in Aromas, then clicking the outline. If the official address for the San Benito County, CA map ever changes, our directory page carries the current link for San Juan Bautista and the rest of the county.
Current and older editions
Try the library in Aromas or a local historical society for older San Benito County editions; libraries sometimes keep past atlases for reference. An old atlas can help trace when a tract close to Hollister split off from a larger farm.
Reading a San Benito County atlas page
A typical atlas page for a township near San Juan Bautista shows sections, roads and streams, with each ownership block labeled. Small parcels and town lots in San Juan Bautista are often too small to label on an atlas page, which is another reason the online map is better for them. For a land purchase near Hollister, rely on the county parcel record and a title search, not an atlas.
Making your own atlas of San Benito County
Names in an older San Benito County atlas can lead you to the right deed in the grantor-grantee index for land near Aromas. Some buyers print the county parcel map at township scale to carry on back roads near Hollister.
