When land near Pleasant Hill catches your eye, the Lafayette GIS map lays out the outline, the owner of record and a parcel ID. This Lafayette guide covers: where that map lives, the fastest ways to search, and the limits worth knowing.
Finding a lot on the Lafayette GIS map
On ground around Moraga, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Getting to the right map
Go first to the Contra Costa County parcel viewer; it covers each tax parcel around Moraga and Orinda. For acreage around Martinez, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. Around Moraga, write down the parcel ID from that panel; each clerk in the county will want it.
Before you lean on the lines
Acreage on the record is an estimate; just a licensed surveyor establishes the real boundary on land around Moraga. For property near Moraga, records update in batches, so a deed recorded last month might lag behind.
Where Lafayette fits in
Lafayette sits in Contra Costa County, California, and the county assessor maps its lots. For a tract near Walnut Creek, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits near Moraga often falls under county rules rather than the town's.
When the map won't load
If the viewer stalls on a phone near Moraga, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
Legal descriptions in California
California uses the Public Land Survey System, so rural legal descriptions near Concord cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Orinda vary in size. Write down the legal description for the tract near Martinez for any title or survey request.
Finding the right lot
By address works best for lots in Lafayette; owner search often wants the surname first. For a parcel near Martinez, a parcel ID is the most reliable search, and it's printed on tax bills.

Land on the county line
