Finding a lot on the McAllen GIS map
Some cities also run their own GIS portal for utilities or zoning; ask city hall in this city whether one exists for land near Edinburg.
Getting to the right map
Begin with the appraisal district map; it covers each tax parcel around Palmhurst and Pharr. If you're looking near San Juan, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For property near San Juan, a pop-up or side panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Before you lean on the lines
Parcel lines are drawn for taxes, not surveyed, so a fence near Alton can sit several feet off the line on screen. For land near San Juan, records update in batches, so a deed recorded last month can take weeks to appear.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Palmhurst, but coverage can be spotty out of town. A printout of the tract near San Juan is a good backup.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Mission are kept by the County Clerk. Long-held tracts near Palmhurst may sit on many deeds, and a title company earns its fee before a purchase.
Which office to call
For assessment questions about property around Palmhurst go to the appraisal district, which maintains the tax roll. Questions about what you can build around Palmhurst are for the local planning and health departments, and the answer depends on jurisdiction.
Where McAllen fits in
McAllen lies within Hidalgo County, Texas, and the county assessor maps its lots. For a tract near San Juan, 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 out by Pharr generally falls under county rules instead.
Reading the legal description
Older tracts around Palmhurst are often described by metes and bounds, which trace the boundary call by call. Platted lots around Granjeno refer to a recorded plat, making them easier to find. Copy the legal description from the record for the parcel near Pharr for any title or survey request.
Troubleshooting the viewer
If the viewer stalls on a phone near San Juan, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
Searching the map
Addresses are the easiest route inside the city; owner names are usually entered last name first, at least around Granjeno. If you're looking near Alton, searching by parcel number never misses, and it carries over to every office in the county.
Layers worth turning on
If you're looking near Mission, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
Printing and saving
Save a screenshot of the lot near Mission and its record panel, so you have it when calling an office.

Inside the parcel card

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.
