BSB is proud to announce the completion of Sunflower Gardens in partnership with developer Interim, Inc. The 2nd LEED Platinum Affordable Project in USA and the 1st in California!



Sunflower Gardens is a green construction, multifamily, affordable housing
project in Salinas, CA.
Sunflower Gardens provides affordable supportive housing for low-income and
very low-income single adults with psychiatric disabilities.
These adults were previously homeless or are currently at risk of homelessness.
Sunflower Gardens’ Leadership in Energy and Environmental Design for Homes
(LEED) Platinum Certification is pending.


Interim’s Sunflower Gardens has been built to the highest standards for energy efficiency. The US Green Building Council sets those standards under the Leadership in Energy and Environmental Design for Homes (LEED for Homes) rating system. LEED ratings evaluate buildings for energy efficiency, water conservation, waste reduction, and indoor air
quality using a ranking system that sets Platinum certification at the highest level. Sunflower Gardens expects to be the first affordable, supportive housing project in
Monterey County to achieve Platinum LEED for Homes certification (application pending).

Sunflower Gardens expects to tie for first affordable, supportive housing project in
California to achieve Platinum LEED for Homes certification (application pending).
