Kendall County, Texas GIS Parcel Map Guide
The Kendall Central Appraisal District web map is the free parcel viewer for Boerne, Comfort, Kendalia, Sisterdale, Waring and the ranch country along the Guadalupe River.

Kendall County sits where San Antonio’s commuter belt meets the limestone hills, so one road can pass a new subdivision and a century-old ranch within a mile. The Kendall CAD web map shows both on the same screen.
The Kendall CAD web map
The appraisal district’s map is built and hosted by BIS Consultants, a Texas firm that runs maps for several districts. A disclaimer opens first and makes three points: the map is informational, it is not an on-the-ground survey, and boundaries shown are only approximate relative locations. It also admits the ownership data is always being corrected and updated. Click OK to reach the map, where a single Search Here box takes an address, owner or property number.
The district recommends turning off pop-up blockers and clearing your browser cache for the best results, and the help link offers email contacts for both the mapping vendor and the appraisal district. Our Texas directory entry for Kendall links the map, and you can also land on the county from our clickable U.S. map.
Finding an account in the Hill Country
Many rural addresses here are long county road numbers, and some tracts have no address at all. When an address search fails, try the owner’s last name, or pan to the tract and click it. The popup gives the property ID, which you can carry to the district’s property search for values, exemptions and improvement details.
- Agricultural or wildlife-management valuation shows up on the account record, not the map, and it can change the tax picture sharply after a sale.
- Boerne city limits and its extraterritorial area matter for building permits; check which side of the line a tract falls on.
How to find property lines in Kendall County
Hill Country tracts are often described by metes and bounds running from one old fence corner to the next, which makes the map a rough guide at best.
- Read the legal description on the account; it will name a survey and abstract, or a lot in a platted subdivision.
- Order the deed and any plat from the County Clerk in Boerne.
- Walk the fence lines with the deed calls in hand, but remember that ranch fences were often built for convenience, not on the true line.
- For a sale, a split or a new fence, hire a Texas registered professional land surveyor.
Creeks, the Guadalupe and floodplain
The Guadalupe River crosses the north side near Comfort and Waring, and Cibolo Creek runs through Boerne. Frontage is a selling point, but these streams rise fast in heavy rain, and floodplain covers more ground than the dry-season channel suggests. Check the flood map before you fall for a creekside lot; see how flood layers work in a county viewer. Texas generally treats the beds of navigable streams as state property, so ask a title company where a river tract’s boundary actually runs.
Wells, septic and rural services
Outside Boerne and a few water supply corporations, homes rely on private wells drawing from the Trinity Aquifer and on septic systems. Groundwater conservation district rules can affect new wells, and septic permits depend on lot size and soil. A small lot on the map may not support both, so ask before you buy.
Kendall County plat book
We did not find a current printed landowner atlas for the county. Recorded plats at the County Clerk are official, and the appraisal district map shows today’s owners without charge.
Ranches, deer leases and the acreage map
Whitetail hunting leases are part of the local land economy. The web map shows acreage and owner for each tract, which is the first step when you want to contact a landowner about a lease. Many large ranches are held in family partnerships, so the owner of record may be a company name rather than a person.
Protesting a Kendall CAD value
Rising Hill Country prices have pushed appraisals up quickly. Owners who disagree can file a protest with the appraisal review board, usually by May 15 or within 30 days of the notice, whichever is later. Bring sales of similar nearby homes or photos of problems the appraiser missed.
Is the Kendall County GIS map accurate?
By its own description, no, not to survey standards. Parcels are drawn from deeds that often trace old fences and live oaks, then placed over aerial photos. Expect shifts, especially on steep, wooded ground. A boundary survey is the only thing that settles a line; see assessment maps compared with surveys.
Web map will not open?
Follow the district’s own tip: disable pop-up blocking for the site and clear the cache, then reload. If the search box stays gray, try another browser. Next door, our Comal County guide covers New Braunfels and Canyon Lake, and the Texas GIS county page lists the rest.
Frequently asked questions
Can I find my property lines without a survey in Kendall County?
You can get a rough idea from the deed, the web map and old fence corners. Ranch fences are often off the true line, so only a surveyor can confirm it.
Does the Kendall CAD map show agricultural valuation?
The map shows parcels and ownership. Agricultural or wildlife valuation is listed on the account record in the district’s property search.
Who records deeds in Kendall County?
The Kendall County Clerk in Boerne records deeds and subdivision plats.
When can I protest my Kendall County appraisal?
Usually by May 15 or 30 days after your notice arrives, whichever is later, through the appraisal review board.

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.
