The Marana plat map: start here
For a subdivision near Apache Junction, look for the plat book reference on the parcel record; use it to request a copy.
The viewer Pinal County publishes
Begin with the Pinal County ArcGIS parcel map; it includes each tax parcel around Apache Junction and Casa Grande. Around Apache Junction, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. Around Eloy, write down the parcel ID before closing the panel; every office in the county asks for it first.
When there's no plat
Rural land near Coolidge that was never subdivided is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Marana, AZ: the basics
Marana sits in Pinal County, Arizona, which means parcel data comes from the county. For property near Apache Junction, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the town limits toward Maricopa often follows county rules rather than the town's.
When a plat changes
Lots near Apache Junction can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements for land near Florence are kept by the County Recorder. For a parcel near Apache Junction, use the document number from the tax record to skip a name search.
A word on accuracy
The acreage figure is an estimate; only a licensed surveyor establishes the real lines on land around Casa Grande. In and around Florence, records update in batches, so a deed recorded last month might lag behind.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Eloy, but coverage can be spotty out of town. A printout of the tract near Apache Junction helps when you meet an owner or agent.
Recorded plat or GIS layer
When the two disagree for a lot near Florence, the recorded plat and a survey control.
