Yes, in California you can absolutely rent out your ADU, and many homeowners do. One of the biggest benefits of building an ADU is the opportunity to generate rental income or provide affordable housing for family. State law allows ADUs to be rented long-term, typically on monthly leases or longer. Short-term rentals, such as Airbnb or VRBO, are generally not allowed unless your city specifically permits them. Most cities require leases of 30 days or more to encourage housing stability.
