Commissioners Approve Accessory Dwelling Unit Code Amendment Near Nederland

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 Board of County Commissioners will review progress on this initiative at their May 29 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Residents in the Gunbarrel area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Public Works at (303) 441-5190 to verify eligibility and requirements.

Community Impact

The project includes improvements along Baseline Road between Gunbarrel and the intersection with Foothills Highway. Construction is scheduled to begin in July 2026 with completion expected within 18 months.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 54% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Resources

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.

Data from the 2025 Boulder County Community Survey shows that 54% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 7,026 responses from residents across the county.
