Where We Build
Dream Dadu designs, permits, and builds detached accessory dwelling units (DADUs) across Seattle and the Eastside. Every city sets its own ADU rules — pick yours for the current code, verified against each city’s ordinances.
DADU Builder in Seattle
Two ADUs per lot, heights matching the main house, zero parking required — some of the friendliest big-city DADU rules in the country.
ADU Builder in Bellevue
Our hometown. Backyard cottages became legal citywide July 2025 — most homeowners don't know yet.
DADU Builder in Redmond
Up to 1,000 sq ft at the zone's 38-ft height max, zero added parking, no owner-occupancy.
DADU Builder in Sammamish
Big lots, 24-ft cottages, 5-ft setbacks — with septic and tree planning handled from day one.
