Do I need parking for a Centennial ADU?
✓ Verified against code · August 20, 2026
Yes — one off-street space in addition to your principal dwelling's spaces, with no conditions attached. This is one of the provisions that puts Centennial at odds with state law, which allows a city to require a new space only when there is no existing usable off-street space, the zone required parking as of January 2024, and on-street parking is barred on the block. Centennial's requirement applies regardless.

How current is this?
Centennial’s ADU rules run under Land Development Code §12-3-603(H) (Ordinance 2024-O-03). Centennial adopted its ADU ordinance in May 2024, a year before Colorado's June 30, 2025 deadline — and then did not revisit it. In October 2025 the state identified Centennial among roughly a dozen jurisdictions not complying with HB24-1152. Two provisions stand out: an unconditional parking requirement that matches none of the statute's three conditions, and a size formula tied to the principal dwelling's footprint with no floor at the 750 sq ft the statute protects. We checked Ordinance 2026-O-07, adopted June 2, 2026, directly: it amends sixteen provisions and none of them touch the ADU or parking sections. We verified this answer against primary sources on August 20, 2026, and every change we catch is logged in the changelog.
