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.

Data from the 2025 Boulder County Community Survey shows that 53% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 5,596 responses from residents across the county.

The Louisville Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 3,919 seniors participated in center programs last year.

Colorado state law requires all counties to provide these services to eligible residents. Boulder County exceeds minimum state requirements by offering expanded hours, multilingual support, and online access. In 2025, the county received a state award for excellence in service delivery.

Residents in the Louisville area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Public Health at (303) 441-1099 to verify eligibility and requirements.

Timeline

The project includes improvements along Niwot Road between Louisville and the intersection with CO-72 Peak-to-Peak Highway. Construction is scheduled to begin in August 2026 with completion expected within 17 months.
