a year or two ago, there was a video circulating of police coming to a home, indicating that the neighbors had complained of the cooking/smoke coming from a BBQ. Some folks in BBQ/grilling groups I participate in were outraged, some thought it was just a local thing and that that unfortunate guy just lived in the wrong city.
I started looking into things myself for other reasons. Ok, well a guy few houses away was firing a gun off one day, and another neighbor was outraged and put up a big fuss about it. Supposedly she had a bullet lodged in her siding at her home, and called the police about it. Now, this particular person and story , I was skeptical about, because IMHO, if she really had a stray bullet lodged in the side of her house, I would fully expect the police to actually site the guy shooting his gun , for something like wreckless discharge of a gun. I started looking at local laws... first to see exactly what laws there were in our township about shooting a firearm and such. I didn't find anything about guns really, presumably the rural township doesn't really have their own laws about guns, and basically state laws are what matters for guns.
But anyway, the guns not the point. While I was looking up local ordinances, I realize that there's a ordinance in my township, that in theory could be used to stop a person from BBQing, if the 'wrong' set of people started complaining. Basically there's a nuisance law, that effectively says ( among other things ), that if you produces smells that are deemed to be a nuisance, you could be in violation of the ordinance. ( loud sounds can also be nuisance ). The way I read the law, and think about it, if you had a neighbor who was annoyed with the smell of your grilling/smoking, and complained, and the local officials sided with the neighbor, you could very likely be told you can't continue to grill/smoke. Now, maybe cooler heads would prevail and you wouldn't get cited , but it made me realize that many of us, are basically at the mercy of our neighbors with regard to what we can and can't do.
