How tall can a Redmond DADU be?
✓ Verified against code · August 19, 2026
Up to the zone maximum — 38 ft base in Neighborhood Residential — because structures containing ADUs are exempt from the 22-ft accessory-structure cap. That's the most generous DADU height in the region.

How current is this?
Redmond’s ADU rules run under RZC 21.04.1110 (Redmond Zoning Code, post-Redmond 2050 restructure) (Ordinance 3220 (recodification); Ord 3261 pending codification). The Redmond 2050 restructure (Ord 3220, effective June 28, 2025) moved ADU rules from RZC 21.08.220 to RZC 21.04.1110 — any source citing the old section number predates the current code. Ordinance 3261 (adopted June 2026) amends the ADU sections further and is pending codification; we re-check on every verification pass. We verified this answer against primary sources on August 19, 2026, and every change we catch is logged in the changelog.
