I'm going to try to answer your question to the best of my ability. If there are any errors in my answer, I'm sure our AZEO will let us know.

Are you asking about a camping trailer? If so, is it parked on the property of 450 Benham Street? If so, here is some information from our town's zoning regulations.

450 Benham Street is a residential address located in residential zone R4. The following zoning regulation applies to that address:

650.3.1 (a) Not more than two such vehicles shall be stored or parked on a lot used for residential purposes for a period exceeding 24 hours per month.

Just a heads up, there is a plethora of other information in our zoning regulations that pertain to your question. If you would like to read our town's zoning regulations in their entirety, you can find them here:

Personally, I wouldn't complain about my neighbors parking their camper on their privately owned property. Complaining about one's neighbors causes a domino effect of everyone looking for reasons to complain about each other, and EVERYONE unwittingly does something that's illegal.

I hope this information helps.
