Catherine, it may be stress that has induced this, but the first step I'd take is a visit to the vet. It's possible that stress has made one of your cats more vulnerable to illness, and that one of them has a urinary tract infection, kidney stones, or some other physical problem that could be causing this. If you want to rule it down to one cat, a call to your vet's office can help you figure out how to narrow it down (likely using a special litter & brief (overnight) confinement of one cat at a time to get isolated urine reactions with the litter).
In the meantime, I'm assuming that in your new home, you're using the same litter boxes (pans, rims and/or lids) and litter brand that you've always been using, and that the boxes are located in places private enough that the cats don't feel vulnerable to attack while using them. I'm also assuming the boxes are scooped on a very regular basis, and that you're not using strong smelling cleaners to clean the boxes (such as bleach or ammonia). Dish soap and/or baking soda should be sufficient to clean the boxes. There's a special cat litter called Cat Attract that may help, if you mix it in with the regular litter.)
The best ratio of litter boxes is at least 1 box per cat (ideal is number of cats plus one), and spread throughout the house wherever the cats are permitted. So, for instance, you might have one in the basement laundry room, 1 on the first floor, and 1 on the second floor.
Good luck!
