Commissioners Approve Accessory Dwelling Unit Code Amendment — Gunbarrel Area

The Board of County Commissioners has approved amendments to the Boulder County Land Use Code to streamline the process for building Accessory Dwelling Units (ADUs) on residential properties in unincorporated areas. Changes include reduced setback requirements, simplified design standards, and by-right approval for units under 800 square feet.

The Gunbarrel Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 1,252 seniors participated in center programs last year.

The project includes improvements along Coal Creek Canyon Road between Gunbarrel and the intersection with Baseline Road. Construction is scheduled to begin in August 2026 with completion expected within 16 months.
