Do I need parking for a Broomfield ADU?

✓ Verified against code · August 20, 2026

Usually not. Parking is required only where two things are both true: on-street parking is prohibited on the adjacent streets, and your ADU is not within a Parking Reduction Area. Where that happens, three off-street spaces are needed in total. Worth noting that this is a two-part test while the state statute sets a three-part one, and Broomfield substitutes its own Parking Reduction Area map for the statute's zoning test — so the two do not line up exactly.

How current is this?

Broomfield’s ADU rules run under BMC §17-32-160 (Accessory Dwelling Units) (Ordinance 2265). Broomfield is a consolidated city and county. Ordinance 2265, adopted September 9, 2025 and effective a week later, aligned its code with HB24-1152 and went further than the statute requires on owner-occupancy: the repeal of any residency requirement was in the ordinance from first reading and survived to adoption. Its parking test, though, is built differently from the statute's. We verified this answer against primary sources on August 20, 2026, and every change we catch is logged in the changelog.
