Build Small, Live Large


If you’re like many Northern California homeowners in Alameda & San Francisco County, you are considering accessory dwelling units (ADUs) as a flexible, long-term investment for your property. Perhaps you need to keep family close, create passive income, accommodate guests, or even help your community solve the affordable housing shortage.New laws make it easier than ever to build a secondary unit on your property.

Whatever the reasons you have for wanting an ADU, building one isn’t easy.


These versatile, single family units, either detached or attached, or garage conversion can be added to a single family home, provided that they meet zoning, lot size, and design regulations specific to your city, county and even neighborhood. While ADU regulations and requirements can be tricky to navigate, it’s relatively easy when you can be walked through the process with an ADU expert who handles every detail for you.
