Jamestown Community Briefing: 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.

The Board of County Commissioners will review progress on this initiative at their June 30 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Affordable housing remains the top priority identified in the 2025 Community Survey. Boulder County’s Worthy Cause program has funded 747 affordable housing units since its inception, with 189 additional units in the development pipeline.

Community Impact

Residents in the Niwot area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Community Planning & Permitting at (303) 441-5056 to verify eligibility and requirements.

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.
