Spokane metro ADU matching
Get matched with a licensed local Spokane ADU builder
Lilac City ADU connects homeowners across the City of Spokane, unincorporated Spokane County, and Spokane Valley with licensed local ADU builders. It is free to you. We are paid by the builder, not by you.
What is an ADU?
An accessory dwelling unit (ADU) is a smaller, self-contained second home on the same lot as a primary house. It can be a detached backyard unit, an attached addition, a garage conversion, a basement unit, or a junior ADU. Spokane-area homeowners build them for rental income, multigenerational living, guest or office space, and added property value.
What we do
We are a marketing and matching service, not a contractor. We connect you with a licensed local ADU builder who serves your jurisdiction, and we publish current, sourced guides on Spokane ADU rules, permits, and cost. The builder you are matched with handles design, permitting, and construction.

Where we help, and the ADU types we match for
ADU rules differ by jurisdiction, so the first step is identifying which one your lot falls under: the City of Spokane, unincorporated Spokane County, or Spokane Valley. We match homeowners for every ADU type, including new detached units, attached ADUs and additions, garage conversions, basement units, and junior ADUs. Use the menu above to open the rules for your jurisdiction or any ADU type.
