Let a crisis become an opportunity! New rules intended to grow more density offer designers a chance to rethink the San Francisco home. Send us your visions for 21st century duplexes and quadriplexes that offer up innovative approaches to lifestyle and architectural style, and show that the single family house is not the only dream home in California. As society grapples with challenges including homelessness, a changing climate and social fragmentation, consider forms of housing that are light on the earth, obtainable in cost and social in nature. —Frances Anderton, Author & Former Host | DnA on KCRW (Los Angeles)

The Housing+ San Francisco 2050 Design Competition seeks design ideas and typologies that address an ongoing housing crisis. How to increase available housing while embracing the character and scale of this city? A large percentage of the city’s land zoned for residential use is designated for single-family homes only. While California Senate Bill 9 (SB9), The California H.O.M.E Act, and proposed San Francisco-focused legislation aim to redress the inequity inherent in current land use patterns, many areas are still affected by being down-zoned from multi-unit to single-family-only in the late ‘70s. This competition seeks solutions for innovative new housing typologies for the city of San Francisco that look to the future, creating more equitable and resilient urban communities.
