about our company

In 2000, partner Stuart Gruendl, co-founded BayRock Residential, the predecessor company to BayRock Multifamily, LLC, to build and develop landmark, multifamily communities.

Today, BayRock Multifamily continues to own and develop outstanding, in-fill apartment and condominium properties.  BayRock’s clear strengths include its customer-centric focus and in-depth, local market knowledge.  We create multiple communities and investments in a local submarket, with a goal of extensive community outreach.  This Investment Builder approach establishes BayRock as a true stakeholder and community member in each of its markets.

Our long term, performance driven perspective today includes a responsible owner mentality, including developing the latest green and environmentally-friendly features in each of our communities. 

BayRock’s success is truly a function of its strong organization and great integrity.  We believe the San Francisco Bay Area is experiencing a dramatic, paradigm shift with extraordinary customer demand for state-of-the-art, 24 hour urban living.  The confluence of consistent, strong job growth, a dearth of suitable multifamily development land, and the emergence of Millenials’ and Baby Boomers’ urban living requirements will continue to be the fundamental demand drivers for our product.
