If they wanted to they could say fuck you then party as loud as they want all night. As long as they're not playing amplified music theres absolutely nothing the Bellevue police will do or can do aside from tell them to relax and they might not even do that. So the policy is warn, warn again, then have the ppl complaining call the police, but in reality theres no real enforcement aside from petty HOA punishments
Of course youll get a fine and maybe evicted if they keep doing it but i don't know why ppl think their neighbors should be burned at the stake any time they have ppl over its ridiculous
