YES! There are a lot of rules about building ADUs. The rules are meant to make buildings safe, to keep cities working properly, and to encourage pleasant living conditions in neighborhoods.
California has a state level policy on Accessory Dwelling Units, but there are also hundreds of independent jurisdictions each with their own unique rules and restrictions. While basic building codes are the same throughout California, local jurisdictions can adopt additional requirements along with their own local interpretations.
As the owner, you will have many decisions to make when building an ADU, and each may involve a rule (or two!) that could affect your choices. While the rules are all publicly available, they can be challenging to find and interpret for a specific property. Working with a local design professional will give you a head start in understanding your community’s rules and requirements from the beginning of your project.
