Cost of building a small guest house in CA?

[lekotuc2]

I’m thinking about adding a small cottage in my backyard for my parents to live in. Does anyone know the current legal requirements in California for these types of detached units? I’m worried about the permits and the overall process being too complicated to handle alone.

Dealing with California laws is a headache, but I’ve been through it. I’d suggest looking into a professional backyard adu specialist to save time. I followed the guide at https://www.aduscale.com/backyard-adu when I was starting out. They break down the legal process for detached units perfectly. It’s definitely easier than guessing the zoning rules yourself!
