Also, you can get a lot of information from perusing the minutes of the last 3 or so meetings of the board. Check to see if there are a lot of pet complaints and what was done about them.

Some associations allow all and any pets. Some will allow one pet, some more. Some condos allow a small dog under a certain weight; many allow one or two indoor cats. Most condo associations allow small caged pets like gerbils, hamsters, fish, and reptiles. But don't assume that any particular condo complex allows any pets at all.
