This certainly isn't a constitutional dilemma. But to engage on the merits...
The issue isn't what goes on inside your home, but instead the "externalites" that your meeting imposes on your neighbors.
When you live in a city with finite parking space in your neighborhood, your neighbors have a right to care about the cars parked on the street in front of their house.
If you disagree, then are there any limits? What if I want to hold a "Phish" concert in my backyard?
