Build a Backyard Cottage in Thurston County

With housing inventory 40% lower than this time last year, it’s time to get creative!

The City Of Lacey worked with Artisans Group to develop two pre-approved Backyard Cottage designs!  Backyard Cottages, also called Accessory Dwelling Units (ADUs), are gaining in popularity due to their versatility. They can provide space for your family, friends and out of town guests, an affordable rental unit, or just a private studio space in your own backyard. Some people even build one to live in and rent out their house. There are so many possibilities and we’re here to help you through the process, step by step. You can customize your roof style, siding, color, windows, and doors.

Benefits of ADU’s

-Density

-Providing Housing for the Middle Class

-Passive Income and Higher Property Values

-Flexible Family Living

Process for Using Pre-Approved Detached ADU Designs

If you would like to use a pre-approved design, here’s the process:

  • Determine Financing- please apply now with The Dorman Team
  • Talk with Planning and Building for general site feasibility
  • Review all restrictive covenants with your HOA, if you have one.
  • Pick up a pre-approved design 
  • Consult with a builder for a more detailed feasibility review and cost estimates

A Complete Permit Application includes:
