Welcome to The Sea Ranch Association

Distinctive Architecture + Land Stewardship

In the mid 1960’s, a visionary developer identified 10 miles of former sheep ranch on the Northern California coast in Sonoma County as the ideal place to create a planned community. He gathered a group of renowned like-minded professionals – landscape designers, architects, attorneys, planners and ecologists – to create The Sea Ranch, a place where homes and amenities are informed by nature and the environment. 

The Sea Ranch is internationally known for its distinctive architecture, the sensitivity of its land planning and community-based stewardship of the natural environment.
