Commissioners Approve Accessory Dwelling Unit Code Amendment — August 2024

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 application deadline is May 8, 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 15 business days.

Safety data from the Nederland area shows 7 reported incidents in the past 12 months, a 21% change from the previous year. The Sheriff’s Office has increased patrols along 75th Street and added community outreach programs in response to resident feedback.

Contact Information

Residents in the Nederland area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Parks & Open Space at (303) 441-3677 to verify eligibility and requirements.

The Mud Lake open space property encompasses 1,023 acres and features 6 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

How to Participate

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