California landscape renderings have to account for things that do not exist in most of the country. Water restrictions that limit how much turf you can install, defensible space requirements in fire zones, hillside grading and drainage, and a Mediterranean plant palette that looks nothing like what ships in a default rendering library. A render built on East Coast or Florida assumptions shows a client a yard they are not legally allowed to build.

Cold climate landscape renderings need cold climate knowledge. Most rendering studios are based in Florida or the Southwest, and it shows the moment they render a northeast property. Palms, tropical foliage, everything in peak bloom at once. A client in Connecticut or Westchester lives with that yard in February for four months of the year, and a render that only shows July is selling half the design.
