Please don’t go there! Private property ownership is sacred! If they aren’t disturbing the peace (parking on street is annoying, but NOT illegal), any gathering on private property is no one else’s business!
It'll always be the fire chief's business. It would not surprise me if one day soon, somewhere in the US, the fire chief got on the case of some large family in a home without enough exits. Then the code guy will command them to make some or get out in x number of days.
Sometimes I think even politically aware folks are just not all that aware of how bad it is in this supposedly free country. If the authorities want to hassle, harass, fine, stifle, incarcerate or DESTROY you, they will find a legal way.
