FAQ ABOUT ADUs
What is an ADU Home?
ADU stands for Additional Dwelling Unit. ADUs are smaller, self-contained living spaces located on or extended off existing property. ADUs are also known as mother-in-law suites, granny flats, casitas, backyard cottages, garage apartments, or basement apartments.
If extended family is coming to live with you, if your adult children are moving back home, or if you want an extra source of income, an Additional Dwelling Unit (ADU) that attaches to your home or is a separate structure on your property will offer privacy and convenience for you and its occupants.
Why should I hire a specialized ADU contractor in San Mateo County?
Navigating local zoning laws, setback requirements, and building permits can be complex. Working with an experienced ADU contractor in San Mateo County ensures that your custom build meets all city and county codes seamlessly while maximizing your property’s available space and overall value.
