“Our backyard ADU was permitted, built and rented within eleven months. Their team knew the Seattle ADU rules better than the consultant we had hired first.”

Seattle Backyard ADU
A detached 640 sq ft rental unit permitted and built in under a year.
Setbacks, lot coverage and tree protection all shaped the footprint before a single line was drawn.
Separate metering and a dedicated sewer connection keep the unit fully independent from the main house.
The unit rented within three weeks of the final inspection.
