You can make a complaint about blocked streets and sidewalks.
Property owners and businesses must keep sidewalks clear of objects that block pedestrian traffic. Objects can include:
Trash containers, including garbage dumpsters, may only be placed on the sidewalk at specific times.
Stores are allowed to have outside displays of merchandise, but they may extend no more than 3 feet into the sidewalk from the building and no higher than 5 feet. ATMs must be placed behind the building's property line or inside the building. Certain streets are designated "zero sidewalk display" streets and generally may not have any items on the sidewalk.
It is illegal to block streets from car traffic unless you have a permit.
