Thanks, I thought that might be it. I found this document months ago when I was doing some research, it was written by an attorney in CA, and it pertains to people who have/breed dogs, but there is some good information here.

Below is a passage which might useful information pertaining to searches.

"5. In some locations dog owners may have obtained special "breeder or rescue
permits" that stipulate that Animal Control has your permission to enter at any
time. If you have signed such a permit they still cannot enter against your
wishes, since you can revoke the permission at any time. However, if you
refuse permission it may allow them to cancel your permit, so you have to
weigh the consequences."
