Boston Snow shovelling

[William Nohmor]

I own a property in Boston and wanted to know how landlords hire contractors for snow shovelling to comply with city ordinances.   Boston  requires the following:

DO:

• Remove snow, slush, and ice from sidewalks and curb ramps abutting your property within 3 hours of snowfall ending (or 3 hours from sunrise if snow falls overnight) as required by law. Violators will be fined (see fines below).
• Remove snow, slush, and ice from the full paved width of the sidewalk and curb ramp or a minimum path of 42 inches wide. Narrow paths encumber carriages and wheelchairs, and properly cleared pathways ensure flow and safety of pedestrian traffic.
• Remove ice to bare pavement or make as level as possible and treat with sand, sawdust or similar material.
• Please clear any snow that may be blocking a handicapped ramp, fire hydrant or catch basin.

DON'T:

• Shovel or plow snow into the street: Violators caught shoveling snow from private property into the street will be fined.
• Overexert while shoveling: Excessive strain from the cold and hard labor may cause heart attacks. Please help out elderly or vulnerable neighbors.
• Leave snow or ice on stairways or fire escapes. All common means of egress must be clear.

Im not sure how to price out the services so I can find a contractor.  I dont think it can be done per storm because some storms last a long time.  How much do you pay per service and how do you control how many service visits the contractor makes.
