Medical office space for lease in Irvine Business Complex

12 buildings with 140,338 SF of medical space available across 34 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.

Of the 12 buildings with medical space listed in Irvine Business Complex this September, seven post no asking rent at all.

Only five publish a direct asking rent, mostly Full Service, at $2.10 to $5.25/SF/month. The rest quote once a practice asks, which is standard and not a warning sign. It does mean a comparison built from listings is a comparison of five buildings out of 12.

One more fact changes the read. Landlords here quote three lease structures: Full Service in two buildings, at $2.10 to $5.25/SF/month; Modified Gross in two buildings and NNN in one building. From the real estate side, the structure is part of the price. On an NNN quote, taxes, insurance and common-area costs come on top, so ask for the operating expense history (what those costs actually ran) before setting it next to a Full Service number. Every lease structure should be approached differently during Operating Expense reconciliations.

Short version: 7 of 12 buildings in Irvine Business Complex post no rent, and landlords there quote three lease structures. Convert every quote to the same basis before any number looks cheap. Is your current lease Full Service, NNN or Modified Gross, and do you know what it costs all in?
