City of Lacey Accessory Dwelling Units

An Accessory Dwelling Unit, or ADU for short, is a second, small dwelling on the same property of a standard single-family home. ADU’s have been around for years, but maybe you’ve called them by other common names like Mother-in-Law or Backyard Cottage or Granny Flat or maybe even Above-Garage Apartment. Whatever you may refer to them as, ADU’s offer an opportunity to help diversify the housing needs of our communities.

The City of Lacey recognized ADU’s as one solution they are implementing to solve the complex housing issue in their city limits. They created two pre-approved ADU plans, one a studio plan of 480 sq. ft and the other a 600 sq. ft one-bedroom plan, to assist in streamlining the approval timeline to approximately two weeks. Pre-approved plans speed up the permitting process because the reviewer knows the plans meet the City’s building codes and design guidelines.

These pre-approved plans are free of charge to Lacey residents; just stop by City Hall or schedule an appointment with a City Planner. Individuals can select the ADU’s roof style, siding, color, windows and doors for compatibility with their existing house and any of their neighborhood’s design requirements. ADU’s work best on a lot that is 10,000 sq. ft or .25 acres and larger. Use of the pre-approved ADU plan is not a requirement from the City of Lacey, but use of your own developed plan is subject to the City’s standard review process.

An ADU can be used as a flexible space for your extended family, friends and out-of-town guests; a private studio in your backyard; or an affordable rental unit. Land conservation and preserving an existing neighborhood’s scale and form are just a few of the benefits of adding an Accessory Dwelling Unit to your property.
