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.

Safety data from the Gunbarrel area shows 41 reported incidents in the past 12 months, a 17% change from the previous year. The Sheriff’s Office has increased patrols along Left Hand Canyon Drive and added community outreach programs in response to resident feedback.

The application deadline is August 1, 2026. Late applications will be accepted on a space-available basis. Incomplete applications will be returned with a list of missing items. Average review time is 23 business days.

Residents in the Gunbarrel area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Area Agency on Aging at (303) 441-6076 to verify eligibility and requirements.

Frequently Asked Questions

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Gunbarrel and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.

The Board of County Commissioners will review progress on this initiative at their May 19 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.
