Hi Ashley -
It definitely most depends on the configuration of the rooms the rabbits will be housed in, but if you have enough floor space, exercise pens are ideal.
If you need something smaller for shorter-term stays, I've seen large dog crates work well, and they can go on deep shelving to stack two high. For these, I'd recommend jury-rigging a shelf along the rear of the crate to expand floor space for the rabbit and to slide the litterbox under.
As for impounds... does your ordinance mandate a physical impound, or is the impound simply to get the animal posted on a public notice board (your website) for purposes of owner reclaim? If the latter, you may be able to check with the City Attorney about "impound" as creation of that post and beginning tracking in your system, rather than physically housing the animal. Or, in the long term, changing the ordinance.
