?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.
?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 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.
