Montgomery County blends master-planned towns, a big reservoir and national forest. The MCAD map search puts all of it, from a Woodlands townhome to a Lake Conroe lot, on one appraisal map.
What the MCAD map search offers
MCAD’s map runs on the same appraisal software platform used by several Texas districts. After you accept the disclaimer, which calls the map a reference product compiled for assessment and not a survey, the search tab lets you look up an account by its street location, the owner, either of the two account numbers (property and Geo), a subdivision or abstract, a market area, or plain coordinates. The basemap is an ArcGIS topographic map, handy for seeing creeks and ridges in the forested north.
The district’s office is on Gladstell Street in Conroe. You will find the link on our Texas directory under Montgomery, and the county is selectable on our countrywide map.
Searching by neighborhood and village
The Woodlands is divided into villages, and many homes sit in large subdivisions with sections numbered in the plat name, such as “Section 12.” The subdivision search handles those better than a partial address. A few more notes:
- Unincorporated areas such as Spring, Porter and New Caney use Houston-area mailing names, so a mailing city does not tell you which taxing units apply.
- Market area search groups similar homes, which helps if you plan to protest a value.
- If a new home is missing, it may still be on the roll as a vacant lot until the next appraisal year.
How to find property lines in Montgomery County
Most homes here sit on recorded subdivision plats, so the process is usually straightforward.
- Copy the lot, block, section and subdivision from the MCAD account.
- Get the plat and your deed from the Montgomery County Clerk, which holds the official property records.
- Locate the corner rods; in wooded lots they may be buried under pine straw, so a metal detector helps.
- Hire a Texas registered professional land surveyor before building a fence, pool or bulkhead.
Lake Conroe lots and the San Jacinto River Authority
Lake Conroe was built by the San Jacinto River Authority, which has a say in docks, bulkheads and other work along the shore. Waterfront lots can look deep on the map, but the usable edge depends on the lake’s elevation and the authority’s rules. Low areas along the West Fork and Spring Creek also carry flood risk; check the flood layer and our primer on flood zones in parcel viewers before buying.
Sam Houston National Forest and rural tracts
The northern part of the county includes a piece of the Sam Houston National Forest, where federal land mixes with private inholdings. Rural descriptions follow Texas abstracts and original surveys rather than a section grid, and the abstract search pulls every parcel cut from one survey. That is useful when a deed describes land as acreage out of a named league or survey.
Utility districts and tax bills
Much of the county’s suburban housing sits in municipal utility districts, and The Woodlands has its own township government with a separate tax rate. Two houses with similar values can have very different bills depending on these units. The account record lists every entity that taxes a property.
Montgomery County, Texas plat book
No up-to-date printed atlas turned up in our research. Plats filed with the County Clerk are the legal record, and MCAD’s map is the practical free view of who owns what.
Timber, acreage and hunting land
East of Interstate 45 toward Cut and Shoot and Splendora, and west toward Magnolia and Pinehurst, larger tracts of pine and hardwood remain. Clicking a tract shows acreage and owner, which is how you find whom to ask about hunting access. Public hunting in the national forest follows Texas Parks and Wildlife and Forest Service rules.
No county zoning, plenty of covenants
Texas counties generally cannot zone, so unincorporated Montgomery County relies on subdivision rules and private deed restrictions. Those covenants can forbid mobile homes, livestock or a second driveway, so pull them from the county clerk before buying.
Is the Montgomery County GIS map accurate?
MCAD says it cannot guarantee the map, and it describes the product as reference only. Subdivision lines usually fit well, while old rural tracts in heavy timber can be further off. Use a survey when the exact boundary matters, and see why the tax map is not a survey.
MCAD map not responding?
Accept the disclaimer again after any reload, since the map will not draw until you do. Refresh if tiles stay blank, and try another browser if searches hang. For Houston itself, see our Harris County guide, or browse the Texas county GIS directory page.
Frequently asked questions
How do I find my parcel number by address in Montgomery County, TX?
Search the address in the MCAD map search or property search. The account shows both the property ID and the Geo ID.
Who controls docks on Lake Conroe?
The San Jacinto River Authority built the lake and regulates many shoreline structures. Check with the authority before planning a dock or bulkhead.
Why is my property line different on the GIS map?
The appraisal map is drawn for tax purposes and fitted to aerial photos. A survey based on your plat and deed shows the legal line.
Is there a free Montgomery County, TX plat book?
We did not find a current printed one. The MCAD map is free, and recorded plats are at the County Clerk.

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.
