There are rescues that will gladly accept 'on call/per diem fosters. I do know of some that will allow an interested family to foster before adopting to make sure everything fits. If you're truly interested, do call around and be truthful with your desires and situation. I'm sure you'll find a rescue that you get what you need as well as give something that is helpful to them. Years ago Frederick was painting their shelter. We were there just looking and much to our surprise ended up bringing a dog home until the paint job was complete. So there are places out there :)
I Have not seen them foster animals in temp housing. Check another place that may be overcrowd
