Key Takeaways

•Local governments can't add extra rules for building a small extra home (like a backyard cottage) on a property with a single-family house.
•They can't force the owner to live on the property.
•The only extra rule they can add is that rentals must be for 30 days or longer—no short-term rentals like Airbnb.

Example

You want to build a small extra home in your backyard to rent out.

The city can't make you live there or add extra rules, but they can say you can't rent it out for less than 30 days at a time.
