How late is too late for a house party?

I did it. I called the police with a very kind noise complaint. A house party down the street was going at 0130. I typically wouldn't care, but this was so loud that I could ask siri what a song was and it told me. The house is three houses away, across the street, on the next block.

For fellow party-poopers, how late did you let it go before you did something?
