Lafayette, California, nestled in the scenic hills of Contra Costa County, is part of the prestigious Lamorinda area — a region known for its top-rated schools, upscale neighborhoods, and strong community identity. As housing demand continues to surge across the Bay Area, Lafayette homeowners are increasingly turning to ADU contractors in Lafayette, CA to add accessory dwelling units to their properties. With median home values well above $1 million, adding an ADU is a smart investment strategy that can generate rental income or provide multigenerational living solutions.
