Tiny Homes

A tiny home is a dwelling that may be built on wheels and is no larger than 400 square feet, including a kitchen, bathroom, and sleeping/living area, and must be built to the Washington State Building Code. The approval process for a tiny home depends on where it's built.

On this page, you can determine whether you need approval of construction plans and inspections from L&I or the local building department where the home is being built.

  • IF you're purchasing a manufactured home of any size, including a tiny manufactured home, then you will need to contact your local building department to find out where it can be located.
  • IF you're building a tiny home somewhere OTHER than where it will be occupied and used, then move on to "building a tiny home" below.
