How to Build an In-Law Unit in California

This book provides essential information for homeowners in California who are interested in building an accessory dwelling unit (ADU) – better known as an in-law unit. In addition, the book is useful for real estate agents and contractors who have clients who desire an ADU.

The author walks the reader through his experience of building an ADU and explains how to navigate the State of California’s ADU laws. The book includes helpful information on selecting the type of ADU to build, complying with local ADU ordinances, choosing professionals to work on the project, designing an ADU, obtaining financing, and creating a budget.

This third edition contains insights and knowledge that the author gained from assisting homeowners with ADUs and from volunteering with the Casita Coalition, a nonprofit organization whose mission is to “unlock the power of small homes in California for everyone.”
