May: 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.

According to Lisa Patel, director of Resource Conservation, this program served 47% more residents in 2024 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Lafayette and the surrounding area,” Lisa Patel said.

The Rabbit Mountain open space property encompasses 1,370 acres and features 10 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Wildfire risk mapping conducted by Wildfire Partners shows that 28% of properties in the Lafayette area are within the wildland-urban interface. Free home assessments are available through the Wildfire Partners program, with rebates of up to $2,500 for mitigation improvements.
