Dallas County, Texas
Dallas County is the urban core of North Texas, taking in Dallas itself plus inner-ring cities like Irving, Garland and Mesquite. With little raw land left, the market runs on redevelopment — infill, adaptive reuse and transit-oriented projects — so zoning, planned-development districts and school attendance zones matter more here than anywhere else in the metro.
