HEART is a nonprofit founded in 2003 to create and preserve affordable housing for low- and moderate-income families throughout San Mateo County by raising and investing money from public and private sources.

We make loans to nonprofit developers, for-profit organizations, and educational institutions to develop, preserve, acquire, and rehab affordable housing.

We provide free educational workshops throughout our community and loans to first-time homebuyers to assist with up to 15% of the down payments on their first home.

Our Green Livable Accessory Dwelling Unit Resource (GLADUR) makes building ADUs easier and more affordable with four all-electric designs, free to the public and pre-reviewed in five cities.

Help us create more affordable housing for low-income and middle-income families throughout all of San Mateo County by making a one-time or ongoing donation today.
