Medical office space for lease in Upland and Montclair
11 buildings with 37,640 SF of medical space available across 20 listed spaces. 10 buildings publish an asking rent; no class has five or more on one lease structure, too few to call a figure typical.
Of the 20 spaces listed in Upland and Montclair this September, only one is 4,200 SF or larger.
The math: eight exam rooms take roughly 3,080 to 4,800 rentable SF, at 385 to 600 SF a room. Here, five listed spaces suit one or two rooms, 14 fit three to seven, and the largest single space is 6,205 SF, about 10 to 16 rooms.
One more fact changes the read. San Antonio Regional Hospital is 1.4 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.
Put together: only 1 of 20 spaces is 4,200 SF or larger, and San Antonio Regional Hospital sits 1.4 miles out. Pay for the distance that matters and negotiate the rest. How far is your current office from the campus you use most?
