I might not have this correct, but wasn't it more of it taking place on property owned by the builder? Wouldn't that right be his/hers/theirs, to forbid any event on their property?

In theory, I guess if one could get a permit to hold an event on their property, I don't think it could be stopped just because. Getting the permit is the fly in the ointment...too many criteria to be met when you're talking about the number of people who might attend.
Coming from a development that was owned for a number of years by the builder, even with residents living in certain areas, this doesn't seem much different.
At build out, things changed in our development, though we only had about 5 acres of common land, but here, there will still be lots of property that is builder owned.

If I'm all off on this TH, just tell me, I'm still not fully awake!
