What Is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary housing structure located on the same lot as your main residence. ADUs can be attached or detached and may include garage conversions, basement suites, backyard bungalows, or over-the-garage apartments.
In a dynamic and family-friendly city like Mission Viejo, ADUs have become especially valuable. Whether you’re looking for additional income, a private space for aging parents, or a studio for remote work, an ADU can provide both flexibility and financial return.
