How much does an office build-out cost and how long does it take?

In the Denver metro in 2026, office build-outs typically run about $40–$150+ per square foot — low-finish open plans at the bottom, high-end executive or tech offices at the top. Construction usually takes about 4–16 weeks+ after permitting, depending on size, finish level, and existing conditions.
