So I've made a call to pretty much every department in Orange County, CA. This is the ONLY regulation: "In addition to the required setbacks in sections 7-9-127, 7-9-128, and 7-9-137, pens, cages, and other structures specifically for keeping animals, other than in the residence, shall be located at least twenty-five (25) feet from any residential window located on an adjoining building site. Exceptions to the above may be provided for by a use permit approved by the Zoning Administrator. (Informational note: The types, number and manner in which pets and animals are kept is to be regulated, if at all, via the Health, Sanitation, and Animal Code by the County Health Officer.)" The thing is, every department says to contact the Health Office, but the Health Office says, "We don't deal with that kind of thing unless you sell it." So, what? There's no laws? I can have as many chickens as I want? I've pored over every line of zoning code and this is all anyone can say: 25 ft from your neighbor's window.
