If you have a specific use in mind for land near Sherman, check the Van Alstyne zoning map first: a district label decides setbacks, lot size and uses. Covered here for Van Alstyne: who controls zoning for a given parcel, how to match a parcel to its district, and when a variance or rezoning comes up.
Which office controls the Van Alstyne zoning map
Inside town or city limits, zoning usually comes from the municipality, so property inside Van Alstyne follows that code. For rural land toward Sherman, the county's ordinance, if any, takes over; confirm with the county office. The quickest way to tell which applies: look for a city limits layer in the Grayson CAD interactive map.
Getting to the right map
Begin with the Grayson CAD interactive map; it covers every assessed parcel in the county, Howe included. For property near Sherman, type 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 Tom Bean, the record panel normally shows the owner of record, assessed acreage, the parcel number and often a sale date.
Zoning is only step one
Even when zoning allows a use near Howe, you still need building permits and inspections; septic or sewer and driveway access are often reviewed too.
Van Alstyne, TX: the basics
Van Alstyne is part of Grayson County, Texas, which means parcel data comes from the county. Out toward Sherman, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the city limits toward Sherman often follows county rules rather than the town's.
Places you'll see on the map
Sherman is the county seat, where most land records are kept. Smaller places on the map include Howe, Tom Bean, Dorchester, and Gunter, where town lots give way to larger tracts. About 146,907 people live in Grayson County (Census estimate, 2023) spread over some 933 square miles. Grayson County was organized in 1846, and some chains of title near Dorchester are long. Features like Hagerman National Wildlife Refuge make handy reference points on the map near Tom Bean.
Finding a parcel's zoning district
Pull the parcel up on the Grayson CAD interactive map, note the parcel number, then compare it to the zoning map from the office covering Van Alstyne. For a home near Gunter, short codes on the map aren't self-explanatory, so read the ordinance chapter for each; the letters vary from place to place.
Neighboring parcel maps
Grayson County borders Bryan County, OK, Love County, OK, Marshall County, OK, Collin County, and Cooke County, and each of those keeps its own parcel map.

For a tract near Tom Bean, the ordinance spells out uses allowed by right, uses needing a permit, and uses not allowed. For a parcel near Tom Bean, overlay districts, whether historic, floodplain or corridor, can add rules on top of the base district.
A word on accuracy
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Tom Bean can sit several feet off the line on screen. Owner names and values update on a schedule, so a recent sale near Tom Bean might lag behind.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Tom Bean, though signal can drop in rural spots. A screenshot of the parcel near Gunter with its ID is a good backup.
Sections, lots and bearings
Rural deeds near Howe commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Platted lots around Tom Bean usually use lot and block from a recorded plat instead, which is simpler to follow. Keep the legal description for land near Southmayd when you talk to a surveyor.
When a plan doesn't fit
For a home near Gunter, expect an application, a fee, notice to neighbors and a public hearing.
Questions for the planning office
Have the parcel ID ready and describe the plan for the lot near Gunter; staff can point to the right section of the ordinance. Also ask whether the lot near Tom Bean is a legal lot of record, because nonconforming lots can carry limits.
