If you're choosing between converting your garage or adding a backyard unit to your property, you should know that you might be able to do both. The State of California has passed new laws (AB-68 and SB-13) which expand local zoning codes for Accessory Dwelling Units (ADUs) statewide. As of January 2020, many single family and multi-family properties properties are allowed to add one ADU and one JADU.
