Boulder combines a small market with a wide rate range: 64 units in 7 buildings, from Spruce Street downtown to Arapahoe Avenue and Baseline Road, at $336 to $678 per m² a year. Units span 5 m² to 220 m², median 54 m².
Spruce Street sits a block from the Pearl Street Mall, in the walkable downtown that Boulder's venture-backed companies compete for — the top of this range. Arapahoe Avenue and Baseline Road run east and south through the research and light-industrial belt near the federal laboratories and the university's east campus, where the rate falls and parking comes with the space.
Boulder's office demand is research-led — aerospace, climate science, software — and the 54 m² median reflects teams of seven to nine rather than corporate departments. Nothing above 220 m² is listed here; a larger requirement usually means a build-to-suit further out towards Gunbarrel. Each card shows floor area, floor and the asking rate per m² per year.
