Changes include reduced setback requirements, simplified design standards, and by-right approval for units under 800 square feet.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $454,000, making it one of the largest collaborative efforts in the county’s history.
