Open House - San Diego Architectural Foundation

San Diego’s largest, free, architectural festival

Open House San Diego is a free annual event that offers the public exclusive access to some of the region's most remarkable buildings and public spaces. More than just a series of tours, Open House provides a unique opportunity to engage with architects, designers, and fellow community members in meaningful conversations about the future of our city. By exploring new and historic spaces, participants gain insight into how the buildings we create, preserve, and repurpose today will shape the San Diego of tomorrow.
