    Building in Federal Way: What You Need to Know

    Federal Way projects are permitted through the City of Federal Way Community Development Department. The city has updated its ADU ordinance to align with state mandates, making detached ADUs more feasible on a wider range of lots. The upcoming Federal Way Link Extension light rail stations are driving transit-oriented development interest in the city center corridor.
