ADU (Accessory Dwelling Unit) is a real estate term you will encounter when buying or selling a home in Ventura County. This page gives you a plain-English definition and explains why it matters.
What it means
California has streamlined ADU rules to encourage more housing, and ADUs can add living space for family, generate rental income, or increase a property's value. Local rules govern size, setbacks, parking, and permitting. A junior ADU (JADU) is a smaller unit created within the existing home. Adding an ADU is a permitted improvement, separate from a property's base assessment under Prop 13.
Why it matters to buyers and sellers in Ventura County
In Ventura County communities like Simi Valley, ADUs are an increasingly popular way to house multigenerational families or earn rental income. Buyers may seek lots with ADU potential, and sellers with a permitted ADU can highlight added value. Brian helps clients evaluate ADU opportunities and understand local rules.
