How current is this?
Boulder’s ADU rules run under B.R.C. 9-6-3(n) (Boulder Revised Code) (Ordinance 8650 (building on Ord 8571)). Boulder spent two decades as one of the country's most ADU-restrictive cities and unwound it in stages: the per-block saturation caps died in September 2023 (Ord 8571), and owner-occupancy ended March 8, 2025 (Ord 8650). Older Boulder ADU lore — caps, waitlists, owner-occupancy — describes a code that no longer exists, but the size limits remain among the region's tightest. We verified this answer against primary sources on August 19, 2026, and every change we catch is logged in the changelog.
