Accessory Dwelling Units (ADUs)


HEART’s latest initiative aiming to increase affordable housing is underway!

Building green accessory dwelling units (ADUs) will soon be easier thanks to GLADUR – HEART’s green and livable accessory dwelling unit resource program.

Interest in ADUs, sometimes known as granny flats or secondary units, has increased significantly. This is due to the severe Bay Area housing shortage and new state laws relaxing local restrictions on building ADUs. Some people see them as an opportunity to downsize, house someone they care about, or rent out for extra income.


Yet with custom designs costing upwards of $30,000 and taking months to develop, HEART sees an opportunity to increase the number of environmentally friendly ADUs built by providing free designs. Reducing design costs for homeowners means they can reinvest a portion of their savings into improved energy efficiency and renewable energy. This will reduce greenhouse gases as well as the energy bills of future ADU occupants.
