Trailers. The Board of Appeals may, upon application and after a
duly authorized hearing under the General Laws, grant permits for
trailers, whether on wheels or not hereafter place on any land within the Town which shall be used or occupied
as a dwelling or residence, or for business, or office purposes, or
storage of material relating to the business, for a period not exceeding
30 days in the aggregate, for any one year. The Board of Appeals may
also grant permits for longer period of time by special exception
to the terms of this section in harmony with the zoning regulations
and statutes, or to do or act anything else in relation thereto. Except
in accordance with a permit granted under this paragraph, no use of
a trailer on the premises shall be regarded as an accessory use to
any business for more than 24 of any 48 consecutive hours; provided,
however, that trailers may be placed on a construction site with a
building project for the duration of said project with a building
permit issued by the Building Commissioner. The location of construction
trailers on a lot shall conform to the setback requirements of the
district unless authorized by the Board of Appeals.
