I would immediately move all your hives back in yard ASAP. Two reasons. You will be grandfathered in if you have a preexisting use, and obviously there is no ordinance banning beekeeping at the moment. W/o a prexisting law, you are presntly legal.
I have 140ish colonies. So all of them will not be moved to my back yard right now. I do understand your philosophy on this matter. Actually due to the number of colonies I have, it truly doesnt matter to me if I have colonies in my back yard or not because I cant fit them all back there now anyway. However it sure is convienant to be able to do a cutout and place the cutout colony in my back yard until I know I have a queen in there or re-establish a queen in it. Needing to move my cutouts/swarms to my outyards and tending to them at the outyards is a pain in my keester!
You're definitely preaching to the choir now, my man!
