Medical office space for lease in Garden Grove
9 buildings with 47,895 SF of medical space available across 20 listed spaces. Five buildings publish an asking rent; no class has five or more on one lease structure, too few to call a figure typical.
Garden Grove's published rents this September come on two different lease structures, and they aren't the same kind of number: NNN in three buildings and Full Service in two.
NNN puts taxes, insurance and common-area costs on top of the rate; Full Service rolls operating costs and utilities into the rate. So a NNN rate and a Full Service 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 $3.88/SF/month here and Full Service $2.30 to $2.35.
One more fact changes the read. Sublease space is listed in two of nine buildings. From the real estate side, sublease space trades a shorter runway for a head start on build-out. That works when the term matches your plans and the landlord's consent is a formality, not a negotiation.
So: landlords in Garden Grove quote two lease structures, and two of nine buildings carry sublease space. The term left on a sublease matters as much as the suite. How many years does your practice need in the next space: three, five or ten?
