? Where are the medical office buildings in Hayward?
The largest cluster is on Calaroga Avenue next to St. Rose Hospital. The building at 27206 Calaroga houses cardiology, orthopedic and internal medicine practices and Stanford Medicine Partners Primary Care Hayward, with more offices at 27171 and 27212 Calaroga. Kaiser's Hayward-Sleepy Hollow Medical Offices are at 27303 Sleepy Hollow Avenue. Other clusters are around Southland Drive and Southland Mall, where Alameda Health System has a clinic, and downtown along B Street and Foothill Boulevard.
? Does Kaiser Permanente still have a presence in Hayward?
Yes, but not a hospital. Kaiser closed its Hayward hospital in 2014 and moved inpatient care to San Leandro Medical Center at 2500 Merced Street. In Hayward, Kaiser operates the Hayward-Sleepy Hollow Medical Offices at 27303 Sleepy Hollow Avenue, which offer pediatrics, adolescent health, allergy, nephrology, urology, lab, pharmacy and a minor injury clinic. For independent practices that want to be near a hospital in Hayward itself, the St. Rose area on Calaroga Avenue is the place to start.
? 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 parking ratio do medical offices need?
Medical offices typically require higher parking ratios than general office space due to patient turnover throughout the day. A common standard is 5-6 spaces per 1,000 square feet, compared to 3-4 for general office. High-volume practices like urgent care or imaging centers may need even more. Verify the property's parking allocation before signing a lease.
? 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.
