A container standing on private property, in a driveway or on a job-site lot, does not need a permit in Salem. The requirement starts the moment any part of it sits in a street, sidewalk, walkway or alley.
Salem handles that through a general obstruction rule rather than a dedicated container permit, and the issuing officer is unusual: the written permit comes from the City Manager, not from an engineering or public works counter. The city code makes it unlawful to obstruct or block a street, sidewalk, walkway or alley without one.
Two things follow from that, and both matter commercially. First, because Salem publishes no container specific terms, there is no stated fee, no stated day limit and no published list of placement conditions, so the answer for your particular spot has to come from the City directly. Second, the remedy for skipping the permit is sharp: if an obstruction is not removed at once after notice, the City Manager can have it removed and recover the cost from whoever caused it, enforceable as a claim.
In practice, nearly every Salem job we handle sits on private ground, and your account manager will look at the approach and the drop point with you when you book. Where the street really is the only option, we will tell you to get the City Manager's written permit in hand before we schedule the delivery rather than after.
