Medical office space · data as of September 2026
Medical office space for lease in Oceanside
10 buildings with 89,670 SF of medical space available across 17 listed spaces. Eight buildings publish an asking rent; no class has five or more on one lease structure, too few to call a figure typical.
Oceanside's published rents this September come on five different lease structures, and they aren't the same kind of number: NNN in three buildings, Gross + Utilities in two and Gross + Electric in one.
NNN puts taxes, insurance and common-area costs on top of the rate; a Gross + Utilities rate leaves part of the operating cost to the tenant; a Gross + Electric rate leaves part of the operating cost to the tenant. So a NNN rate and a Gross + Utilities rate can't be compared until both are converted to total occupancy cost (rent plus everything the lease adds on top). NNN runs $2.50 to $3.25/SF/month here, Gross + Utilities $2.95 to $3.00 and Gross + Electric $2.00.
One more fact changes the read. Tri-City Medical Center is 1.1 miles from the center of the trade area. The lease read: distance to a campus is the one thing about a suite you can't build, negotiate or fix later. Pay for the location you need, and make the buildings compete on everything else.
Short version: landlords in Oceanside quote five lease structures, and Tri-City Medical Center sits 1.1 miles out. The address is fixed the day you sign; almost everything else is negotiable. How often does your practice make the trip to Tri-City Medical Center now?
