Moving In or Renting Out

What Happens After Your ADU Is Built

Moving In

Once you’ve passed the final inspection, your ADU is ready for occupancy. Whether it’s for you, a relative, or a tenant, the unit must meet Kirkland standards.

Renting Out Your ADU

Renting long-term or short-term? Here's what to know:

• You’ll Need a Business License

  Renting out any unit in Kirkland requires a business license.

• Planning to Use Airbnb or VRBO?

  Short-term rentals must: 

  • Be hosted on owner-occupied properties
  • Be registered with the City
  • Follow short-term rental rules

• Know Your Legal Obligations

  You must follow:

  • Fair housing laws (no discrimination)
  • State tenant laws
  • City codes for occupancy, safety, and use
