Medical office space for lease in El Cajon and East County
13 buildings with 30,556 SF of medical space available across 19 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.
El Cajon and East County lists 19 medical spaces this September. Only one is 4,200 SF or larger.
At 385 to 600 rentable SF per exam room (the room plus its share of waiting, work areas and halls), 4,200 SF holds about 7 to 10 rooms. Most of what's listed here is smaller: nine spaces suit one or two rooms and eight fit three to seven. The largest single space is 4,454 SF, about 7 to 11 rooms.
Here's the part that gets less attention. Landlords here quote two lease structures: NNN in five buildings, at $1.80 to $2.70/SF/month, and Modified Gross in three buildings. 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 Modified Gross number.
Put together: only 1 of 19 spaces is 4,200 SF or larger, and landlords there quote two lease structures. Comparing rates without converting structures compares labels. When you set a quote here next to your current rent, are you comparing the same structure?
