Commissioners Approve Accessory Dwelling Unit Code Amendment — April 2026

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.

Residents in the Longmont area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Transportation at (303) 441-5993 to verify eligibility and requirements.

The Betasso Preserve open space property encompasses 233 acres and features 9 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Contact Information

Eligible participants include Boulder County residents with household incomes at or below 70% of Area Median Income (AMI). For a family of four, this is approximately $50,000 per year. Applications are processed on a first-come, first-served basis.
