?Why is Greenbrae considered Marin's medical hub?
Greenbrae is home to MarinHealth Medical Center, Marin County's largest hospital with 327 beds. It is a Level III trauma center that, according to MarinHealth, receives about 70% of the county's ambulance traffic. Its 260,000-square-foot Oak Pavilion opened in fall 2020, and the hospital has a strategic alliance with UCSF Health. Specialists who want to be close to its surgery, imaging and emergency services tend to lease space on South Eliseo Drive and Bon Air Road.
?What other hospitals serve Marin County?
Besides MarinHealth Medical Center in Greenbrae, Marin has two other acute-care hospitals: Kaiser Permanente's San Rafael Medical Center and Sutter Health's Novato Community Hospital. MarinHealth is the county's largest hospital and its trauma center, which is why many independent specialty practices in Marin look first at the Greenbrae area.
?Should I lease space near a hospital?
Hospital proximity offers advantages including referral relationships, shared patient populations, and perceived prestige. However, hospital-adjacent properties often command premium rents. Consider whether your specialty benefits from hospital proximity (surgeons, specialists) or whether a community location might better serve your patient base (primary care, pediatrics, dentistry).
?What is a second-generation medical space?
Second-generation (2nd gen) medical space is a suite previously occupied by a medical tenant that retains clinical infrastructure like plumbing, electrical, and possibly exam room layouts. Leasing 2nd gen space can significantly reduce build-out costs and timelines compared to shell condition, though modifications may still be needed to suit your specific practice requirements.
?What factors influence medical office rents in California?
Medical office rents vary with location (proximity to hospitals and medical corridors), building quality and age, the condition of the space (second-generation medical space with existing exam rooms and plumbing typically leases for more than shell space), lease structure (NNN versus full-service gross), the tenant improvement allowance offered, parking availability, and local supply. Rents also tend to be higher in supply-constrained markets such as Palo Alto and San Francisco than in suburban markets.
