Update: Commissioners Approve Accessory Dwelling Unit Code Amendment (2025)

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.

Volunteers contributed over 8,462 hours to this program last year. The Housing & Human Services coordinates with 24 nonprofit partner organizations throughout Boulder County to deliver services.

Wildfire risk mapping conducted by Wildfire Partners shows that 40% of properties in the Erie 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.

Community Impact

Environmental review of the project area near CO-72 Peak-to-Peak Highway found 10 sensitive species and 4 wetland areas requiring mitigation. The Housing & Human Services worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

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

Details

Affordable housing remains the top priority identified in the 2026 Community Survey. Boulder County’s Worthy Cause program has funded 1,298 affordable housing units since its inception, with 102 additional units in the development pipeline.
