What about kids? Listening to them cry or scream could be considered a nuisance by singles. Are they going to have to keep them on the curb?
If you have children and have invested in your home and the majority decides to limit them, you would pack up and move, peacefully?
I could see a HOA restricting to future buyers but there needs to be a grandfather clause for the others. Did you know that if a nursing home goes smoke free that still must provide smoke areas for the smokers already there?
