HEART publishes free construction plans for building small backyard homes

San Mateo, CA – HEART of San Mateo County (HEART) is excited to provide free construction plans to help homeowners build accessory dwelling units (ADUs), also known as granny units, in their backyards.

In collaboration with OpenScope Studio Architects and the Bay Area Air Quality Management District, HEART produced four sets of ADU plans. Homeowners can choose between a studio unit, two unique one-bedroom options, and even a larger two-bedroom unit. Homeowners can also choose from a variety of architectural styles, including craftsman, modern, or post-war.

“We want to give homeowners an option to pick a style they like or to better match the ADU to their existing home,” said Boris Vatkin, HEART’s ADU Program Manager.
