When a listing near Calipatria mentions a lot number, the Imperial plat map is where those numbers come from. This Imperial guide covers: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
Who keeps the Imperial plat map
For a lot in Imperial, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Where the parcel data lives
Go first to the Imperial County ArcGIS parcel map; it covers each assessed parcel from Westmorland to Holtville. For acreage around El Centro, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Calipatria, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
When a plat changes
Lots near Westmorland can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near Holtville show up in the records too.
A word on accuracy
The acreage figure is an estimate; only a licensed surveyor sets the real boundary for a parcel near Calexico. For property near Brawley, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Offices that can help
Deeds, mortgages and recorded plats for land near Calipatria come from the County Recorder, usually searchable by name or document number. Questions about what you can build around Brawley need the planning or permitting office, depending on whether the land is inside town limits.
A quick look at the area
El Centro holds the county offices, where most land records are kept. You'll also find Brawley, Holtville, and Calexico. Around 179,057 people live in Imperial County (Census estimate, 2023) on some 4,176 square miles. Landmarks such as Colorado River and Cibola National Wildlife Refuge are easy to spot when you zoom out from Brawley.
Metes and bounds instead
Acreage around Brawley outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Calexico.
Sections, lots and bearings
California is laid out under the Public Land Survey System, so rural legal descriptions near Holtville cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Calexico can be irregular. Keep the legal description for land near El Centro before you request a deed or survey.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Brawley, but coverage can be spotty out of town. A printout of the tract near Westmorland helps when you meet an owner or agent.
Imperial, CA: the basics
Imperial is part of Imperial County, California, which means parcel data comes from the county. Out toward El Centro, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the city limits near Westmorland generally answers to county rules rather than the town's.
Recorded plat or GIS layer
The Imperial County ArcGIS parcel map draws parcels for taxes, while the recorded plat is the legal document.
Where the recorded documents are
The map is an index, not the title: deeds, subdivision plats and easements for land near El Centro sit with the County Recorder. Older tracts near Calexico may trace back through several deeds, so a title company can sort it out on a real sale.
Land on the county line
Imperial County borders La Paz County, AZ, Yuma County, AZ, Riverside County, and San Diego County, and each of those keeps its own parcel map. Ground near Calexico that runs to the line can show up in two county records, so look at the neighboring map too. For a home near Calipatria, the Platbookmapper state page lists every neighboring county map for California.

Recorded easements around Holtville limit where you can build or fence; read the notes on the sheet.
Ordering the Imperial plat map
On ground around El Centro, some counties put plat images online, while others require a visit or a request; copy fees are usually small.

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, especially for fences, setbacks, or boundary disputes.
