No animals inside any premises but outside is okay. Lots of great trails and the grounds have stunning views.
Dogs are not allowed inside the mansion but people have got the dogs chained and in the ground behind the mansion.
I didn’t see any pets inside the house - I think you’re only allowed service animals. On the grounds (free) you are probably okay. Update: Per their website FAQ no pets are allowed in the mansion, gate lodge, or garage. No emotional support animals. Pets are allowed on mansion grounds but must follow Portland city regulations. ADA service animals are allowed.
