Can You Build an ADU on Your Property?

Building an ADU in California is now easier than ever.

If you’re just starting to explore whether you can add an ADU on your property, you probably have a long list of questions. Cost, design process, interior decoration-- maybe you’re already even thinking about whether you’ll put the TV to the left or the right side of the kitchen.

Your dreams can become a reality! But before we get there, we need to answer some questions. In fact - the most basic question:

Are you legally allowed to build an ADU on your specific property?

This used to be a very difficult question to answer. Every municipality in California had different rules about what you could or couldn’t build in your backyards; many towns or cities forbid ADU construction outright.

But that changed in 2020, when a series of new California ADU laws - AB68, SB13, AB881, AB670- came into effect. These laws vastly increased the number of eligible properties for ADU development.

This created an enormous amount of new possibilities for the properties of California homeowners. Every municipality in the State is now required to allow ADU development on single family residential properties.

In order to get a definitive answer on your property’s ADU eligibility, you’ll need to order Housable’s property report. But in the meantime, you can get important information about your property’s eligibility for free!

Housable’s free property check tool gives you the ability to run a preliminary search on your exact property. This tool can help you start to answer your questions about your property. Try it now!
