What are Casitas - Accessory Dwelling Units (ADUs)?
Accessory Dwelling Units (ADUs), also known as Casitas, are small, standalone homes located on the same lot as a larger, primary house.
ADUs, or accessory dwelling units, can range in size up to 1,200 square feet. These compact units provide a flexible and affordable housing solution that can serve multiple purposes. They can be used as home offices, rental properties, or living spaces for aging family members, offering homeowners a wide range of opportunities.
Thanks to California’s new zoning changes, Casitas are now allowed in various residential zones, enabling residents to enhance their property’s functionality and value.
