Do I have to live on the property in Centennial?
✓ Verified against code · August 20, 2026
No, there is no occupancy requirement at any point. But if you will not live in either unit, you must register the ADU — paying a fee and sending certified-mail notice to adjacent neighbours — and renew that registration annually with fresh notice each year. Whether an annually renewing obligation is the kind of ongoing requirement HB24-1152 bars is an open question no source we found resolves.

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.
