When land near San Juan catches your eye, a look at the Alamo GIS map gives you lines, owner names and parcel numbers. What this Alamo guide covers: which viewer to open, how to search it, and what to double-check with records.
Opening the Alamo GIS map: start here
In most places the county maintains the parcel layer, so for Alamo the go-to is the appraisal district map.
Opening the official parcel viewer
Property in and around Donna are published on the appraisal district map, free to use and open without a login. If you only know roughly where the land is, zoom in from San Juan and select the outline. Around San Juan, the parcel card usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Reading the legal description
Older tracts around Donna commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Town lots near Weslaco usually use lot and block from a recorded plat instead, making them easier to find. Copy the legal description from the record for the parcel near Weslaco when you talk to a surveyor.
Alamo and the county around it
Alamo lies within Hidalgo County, Texas, and the county assessor maps its lots. In and around Hidalgo, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Land beyond the town limits out by Weslaco often falls under county rules rather than the town's.
Searching the map
By address works best for lots in Alamo; owner search often wants the surname first. For a tract near McAllen, searching by parcel number never misses, and it carries over to every office in the county.
Getting answers from the right desk
