Do I need parking for a Bothell ADU?
✓ Verified against code · August 19, 2026
No — and not because of an ADU exception. Bothell repealed minimum off-street parking requirements citywide in 2025. Any source telling you an ADU needs a space is quoting the pre-2025 code.

How current is this?
Bothell’s ADU rules run under BMC 12.14.135 (Bothell Municipal Code) (Ordinance 2415 (amended by Ords 2445, 2461)). Bothell adopted its core ADU rewrite in March 2024, then kept going: a December 2024 amendment, and in July 2025 Ordinance 2461 repealed minimum off-street parking citywide and capped ADU impact fees at half the principal-unit rate. Its residential zones were also renamed in 2025 — older guides cite zone labels that no longer exist. We verified this answer against primary sources on August 19, 2026, and every change we catch is logged in the changelog.
