What The Sea Ranch Association does

The Sea Ranch Association (TSRA) is a private homeowners association incorporated in 1964 to govern The Sea Ranch, a 3,600-acre planned community spanning approximately ten miles of the Sonoma County, Northern California coastline. The Association serves 2,200+ member homeowners across 2,284 lots (1,800 developed), enforcing covenants, conditions, and restrictions through a professional Design Committee that approves all construction and landscaping plans. Membership is automatic upon property purchase and funded through recurring homeowner assessments plus utility revenue from wholly-owned The Sea Ranch Water Company and the Sea Ranch Connect fiber optic internet service (partnered with GigabitNow since 2016).

The Association's operational portfolio includes three recreation centers (Del Mar, Ohlson, Moonraker) with pools, tennis, and pickleball courts; over 50 miles of hiking, biking, and equestrian trails; six public access beaches (managed in coordination with Sonoma County Regional Parks); an equestrian center with 16 stalls; a private airstrip (FAA ID CA51); the non-denominational Sea Ranch Chapel (1985, James Hubbell design); and an 18-hole golf links operated as a separate private business. Technology infrastructure supporting these operations includes the tsra.org member website, SimplyBook.me-based reservation system, Everbridge-powered TSRAlert emergency communications, and community-wide fiber connectivity. The Association employs 80+ staff across its main office, Environmental Planning + Design office, Onsite Wastewater Disposal Zone, and recreation facilities.

The Sea Ranch traces its origin to Oceanic Properties, Inc., whose 1962 site selection by architect Al Boeke and 1964 master plan by landscape architect Lawrence Halprin established the "living lightly on the land" design philosophy. Building designs by Moore Lyndon Turnbull Whitaker (Condominium One, 1965) and Joseph Esherick established the architectural vocabulary recognized by the SFMOMA and documented through publications and an audio walking tour narrated by original architect Donlyn Lyndon. Distribution occurs primarily through direct member access (ID-controlled facilities) and an indirect channel via vacation rental agencies (Beach Rentals, Grand Welcome, Sea Ranch Escape, Sea Ranch Living, Utopia, Vacasa) that expose non-owners to the community as prospective buyers.
