OH! San Diego

San Diego’s largest, free, architectural festival

Celebrating architecture, urban design, & the built environment.

Open House San Diego is a free, annual public showcase that promotes appreciation of San Diego’s urban environment through behind-the scenes access to and information about buildings and public spaces. It’s an exciting opportunity for you to learn about the importance of thoughtful and innovative architecture, urban planning and design. Through Open House you have the opportunity to dialogue with architects, design enthusiasts and neighbors about the future of our city and participate in building a more vibrant civic life. The buildings and spaces we build today – as well as those we protect and repurpose – will define the San Diego of tomorrow.

OH! San Diego 2025 is March 8 & 9!
