Interested in a Second Unit?

We want to hear from you about our free green ADU preliminary designs. 

With custom second unit, or Accessory Dwelling Unit (ADU), designs costing thousands of dollars and taking months to develop, we want to help homeowners build environmentally friendly ADUs by providing free designs! HEART will also be working with cities in San Mateo County to pre-review the plans to further speed up the cities’ approval process.

Through our GLADUR program, the designs are estimated to be completed by early summer and we want to provide the public with a preview of the floor plans and elevation designs as well as a variety of environmentally sustainable features for you to include in your ADU.

Go to our website to view the designs, green features, and accessibility options, and tell us what you think here.

•   Check out a variety of layouts: including a studio, 1-bedroom, and 2-bedroom plans
•   Learn about different architectural styles and green amenity options
•   Provide your feedback and ideas that will help guide us!
