Tacoma is Pierce County's largest city, and its more affordable land compared with Seattle has made detached DADUs and backyard cottages an increasingly popular way to build equity. Washington's HB 1337 streamlined ADU permitting across the state, so Tacoma homeowners can add a unit without the old owner-occupancy restrictions. The builders below specialize in Tacoma-area ADU and DADU projects.

ADU FAQs for Tacoma

Do Tacoma homeowners still face owner-occupancy rules for ADUs?

No. HB 1337 removed owner-occupancy requirements across Washington, so Tacoma homeowners can build and rent an ADU or DADU without living on-site. Pierce County's more affordable land often leaves room for a detached backyard cottage.

Who issues ADU permits in Tacoma?

ADU and DADU permits in Tacoma are issued by the City of Tacoma's Planning & Development Services department. Detached units typically require building review, and sometimes site and utility review.
