September: Commissioners Approve Accessory Dwelling Unit Code Amendment

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.

Water quality monitoring at 18 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2024. The Assessor’s Office publishes quarterly water quality reports on the Boulder County website.

A community information session will be held at the Niwot library on Friday, May 8 at 6:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

Frequently Asked Questions

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

The project includes improvements along Flagstaff Road between Niwot and the intersection with Arapahoe Road. Construction is scheduled to begin in July 2026 with completion expected within 12 months.

Eligibility

The program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 53% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
