We don't even HAVE a HOA. We deliberately avoided them when shopping for a house. Saw some nice possibilities - but then discussed it and decided to avoid them, so we told the realtor not to show them to us.

Turned out it was in the city CC&Rs for the property anyway. I can't legally have any livestock here, either, or any pets beyond 4 'typical' - which I believe they mean 'cats or dogs' - although I expect small indoor pets wouldn't ever get noticed.
