What Exactly is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary living space on your property. Our team specializes in attached ADUs, which connect to your main home and share at least one wall. These units are perfect for generating rental income, housing family members, or creating a private guest suite. For official state guidelines, visit the California HCD website on ADUs.
