What is an ADU?

An Accessory Dwelling Unit (ADU) is a self-contained living space found on the same property as a single-family home. ADUs vary in size, typically ranging from 150 sq ft to 1,000 sq ft or more, depending on local regulations. They include designated areas for living, sleeping, sanitation, and eating. While some ADUs are tiny homes, not all are considered tiny homes. ADUs are often compact, modular, and prefabricated off-site.

They serve as secondary dwellings, perfect for uses like guesthouses, home offices, or convenient housing for family members without compromising privacy. Depending on local zoning laws, ADUs can also generate rental income, making them a valuable addition to your property and potentially boosting its value.
