Even though we are "allowed" to have chickens in our subdivision (surprise!0, even that could be reniged if they were creating a "disturbance" being too loud or too smelly.
Before we got them, I went to the neighbors on either side of me and the two behind me to give them a heads up and gage their opinion. If anyone would hear them, it would be these neighbors. They all were totally OK with it, and one did express some concern that we were planning on putting the coop on the property line I share with him, but not because of the noise or smell, but because he has a bird crazy Jack Russell Terrier. I agreed that that would be a problem, to constantly having that dog be tempted and barking at the chickens just on the other side of the fence, so we put the coop instead on the other side of our property.
We have had no issues at all, and I attribute that to a wickedly cute coop, being really good about keeping their coop dry (and so smell-free) and giving out eggs when I can! Most people think chickens mean trashy coop/smell and that is what makes them freak out. If you do it differently, you can show them what chickens really can be!
Good luck!
