When a deed near Granjeno says lot and block, look up the Alton plat map it refers to. Covered here for Alton: where to request a copy, plat versus tax map, and the details that matter to buyers.
Getting started with the Alton plat map
For a lot in Alton, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
The free map to start with
Begin with the appraisal district map; it covers each assessed parcel from Palmhurst to Mission. For a parcel near Mission, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a tract near Palmhurst, write down the parcel ID before closing the panel; every office in the county asks for it first.
Land outside a subdivision
Acreage around Palmview outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.
Legal descriptions in Texas
Older tracts around Palmview commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Subdivision lots in Granjeno refer to a recorded plat, which is simpler to follow. Keep the legal description for land near Palmhurst when you talk to a surveyor.
Where Alton fits in
Alton sits in Hidalgo County, Texas, which means parcel data comes from the county. On ground around Edinburg, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the city limits near Palmhurst generally falls under county rules rather than the town's.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near McAllen, though signal can drop in rural spots. A printout of the tract near Mission helps when you meet an owner or agent.
Where the recorded documents are
For anything that matters, get the recorded deed through the County Clerk; the viewer just points to it, and that holds around Edinburg too. Long-held tracts around Edinburg can go back through many deeds, so a title company is worth hiring before a purchase.
How a plat differs from the tax map
If the tax map and plat differ near Palmhurst, trust the recorded documents over the GIS layer.
Before you lean on the lines
The acreage figure is an assessed number; only a licensed surveyor sets the real boundary on land around Granjeno. For land near Granjeno, records update in batches, so a deed recorded last month might lag behind.
