In the last chapter, we talked about what an ADU is and the different types of ADUs that can be

built on residential properties.

Now we’re going to talk about something that has dramatically changed the ADU landscape in

California over the past decade.

And that is state housing laws.

These laws are one of the main reasons ADUs have become so popular.

They have made it significantly easier for homeowners to build secondary housing on their

property.

But at the same time, many homeowners feel overwhelmed by the rules and regulations

surrounding ADUs.

So in this chapter, we’re going to simplify things.

We’ll walk through the key ideas behind California’s ADU laws so you can understand what they

mean for your property.
