Medical Office Space in Greenbrae.

Greenbrae Healthcare Real Estate Market

Greenbrae, a central Marin community along the Corte Madera Creek between Larkspur and Kentfield, punches far above its size as the healthcare capital of Marin County. The market is anchored by MarinHealth Medical Center on Bon Air Road — the county's only full-service acute care hospital, a UCSF Health affiliate whose modern Oak Pavilion opened in 2020 — and the surrounding Bon Air Road corridor holds the densest concentration of medical office buildings in the county, serving specialists, surgical groups, imaging, and physician practices affiliated with the hospital campus. Demand comes from one of the most favorable patient bases in California: Marin County combines high household incomes with one of the oldest median ages in the Bay Area, driving sustained need for orthopedics, cardiology, oncology, ophthalmology, and other senior-weighted specialties. Supply is tightly constrained — Marin's strict development environment means little new medical construction, so well-located suites near the hospital are prized and second-generation medical space rarely sits vacant. Access via Highway 101 and Sir Francis Drake Boulevard puts the corridor within a 15-minute drive of most of central and southern Marin, making Greenbrae the default location for specialists serving the county.
