Our previous house had 23, if you count the two garage doors and two outside sheds (2-panel sliding door in each shed counted as one), but of course not counting the three gates in the privacy fence. (4,800 sq ft inside.)

We downsized a bit, to our present 9** in the house plus two in sheds outside. (740 sq ft inside.) I suppose I could count the rear door (ramp) in the trailer out in the back, since that's where we store the mobility scooters and some of the camping stuff ... but we only open that one about 3 times a year.

** Three of the nine would technically be "doorways" since they could (should?) have, but don't have, an actual door in the opening.
