Build or buy in Denver County?
Building a median-size new home in Denver County costs about $109,327 more than buying the typical existing one. That gap is wider than the Colorado average of +11.5%, because existing homes here are cheaper than elsewhere in the state.
The two sides are not the same product: the build is brand new at the median new-home size for the West, the existing home is typically older and smaller. Lot cost uses Colorado's average land share, and local lot prices can be well above or below it. Full Colorado build-vs-buy comparison

What builders declared on Denver County permits (2025)
The average declared valuation was $323,810 per home, against our $464,000 estimate for a 2,000 sq ft mid-range build. The two measure different things: builders declare a valuation for permit-fee purposes, which routinely understates finished cost, and permits cover homes of every size and finish level. We show both because quoting only the flattering one would be dishonest.

What land adds on top
