View All FAQs? Is there a hospital in Brentwood?
No. Brentwood does not have its own hospital. The nearest acute-care hospitals are in Antioch: Sutter Delta Medical Center, with 141 licensed beds at 3901 Lone Tree Way, and Kaiser Permanente's 150-bed hospital at 4501 Sand Creek Road. Both have emergency departments, according to state HCAI facility records. Contra Costa Regional Medical Center in Martinez is the county-run hospital. Brentwood's largest medical sites are outpatient: John Muir Health on Balfour Road and Sutter Health on John Muir Parkway.
? Where are the main medical offices in Brentwood?
The two largest outpatient hubs belong to different health systems. John Muir Health's Brentwood Outpatient Center at 2400 Balfour Road offers primary and specialty care, imaging, lab and seven-day urgent care. Sutter Health's Brentwood Care Center at 350 John Muir Parkway, between Thomas Road and Ventura Drive, has family doctors, specialists and a lab. Contra Costa Health's Brentwood Health Center is at 171 Sand Creek Road. For an independent practice, the health system you refer to most is a practical way to choose between these areas.
? Which specialties are available at Brentwood's outpatient centers?
John Muir Health's Brentwood Outpatient Center lists cardiology, endocrinology, gastroenterology, general surgery follow-up, medical oncology, podiatry, psychiatry, pulmonology, rheumatology, urology, pediatrics, imaging and lab services, and its pediatric cardiology, gastroenterology, neurology, ENT, surgery and urology specialists come from Stanford Medicine Children's Health. Sutter's Brentwood Care Center lists primary care, children's health, pregnancy and women's health, orthopedics, gastroenterology, heart and vascular care and podiatry.
? What factors should medical practices consider when choosing a location?
Key site selection factors include: proximity to referral sources and hospitals; patient demographics and population density; visibility and accessibility (parking ratios, ADA compliance); competitor proximity; zoning and permitted uses; co-tenancy with complementary healthcare providers; and ease of access for patients including public transit options in urban markets.
? 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.
