Do I need parking for an Auburn ADU?
✓ Verified against code · August 20, 2026
Only if you are more than a half-mile walk from a major transit stop — within that distance no parking is required at all. Beyond it, one on-site space per ADU applies.

How current is this?
Auburn’s ADU rules run under ACC 18.32 (Accessory Dwelling Unit Development Standards) (Ordinance 6959 §1 (Exh. A)). Auburn's ADU chapter dates to Ordinance 6959 in 2024 and has not been amended since — unusual among the cities in this ledger, most of which have amended twice. Auburn spans King and Pierce counties, but applies Title 18 uniformly across both portions; county code does not govern inside city limits. Auburn is also one of the few cities here that sets a minimum ADU size as well as a maximum. We verified this answer against primary sources on August 20, 2026, and every change we catch is logged in the changelog.
