Did you know that Rancho Cucamonga homeowners can add a residential unit on their property? These units are called Accessory Dwelling Units or ADUs. There are different reasons why you would want to build an ADU, maybe your grown child needs a space of their own, or your elderly parents need to downsize, or maybe you want to rent it for additional income. There are different types of ADUs available such as attached to your existing home, detached from your existing home, or a conversion of a garage or existing unit. You can construct a new unit from the ground up, or you can purchase a pre-fabricated unit. Regardless of your preference, an ADU can be the perfect solution to your or your family’s living arrangements.
For some people the process may seem confusing or even a bit overwhelming, but not to worry, the City has you covered. Our Accessory Dwelling Unit Handbook easy to read guide explains what an ADU is, the different types of ADUs, general requirements, and steps needed to build an ADU. It also includes a helpful contacts page and several resources to get you started.
