What the numbers mean for a buyer
At +44.0% since 2010 this is one of the fastest-growing counties in Texas. Expect active subdivision platting, utility districts (MUDs) extending into formerly agricultural land, and road projects that can change access and frontage between the date a listing was written and the date you close. Zoning and ETJ (extraterritorial jurisdiction) boundaries are the constraints that move fastest in counties like this.
TerraIQs carries 22,033 scored parcels across Kendall County's 662 square miles — about 33 per square mile. That profile is large working tracts rather than subdivided lots, so soil, water and legal access carry most of the value.
Flood risk in Kendall County
Kendall County has 338 mapped Special Flood Hazard Area polygons. A parcel-level check matters because SFHA boundaries follow drainage, not property lines — adjacent parcels can carry completely different flood obligations, and a lender will require flood insurance on a structure in Zone A or AE.

What due diligence in Kendall County involves
The county-level numbers above tell you what to expect; they don't settle any individual parcel. The checks that decide a deal — legal access, title exceptions, mineral severance, septic suitability, agricultural valuation rollback — are parcel-specific and partly document-based. Our Texas land due diligence checklist walks the full sequence in the order we'd run it, including which steps are free and which are worth paying for.
In Kendall County specifically, note that pipeline crossings are common across Texas and are invisible from the road — pipeline easements restrict where you can build permanently.
