Zero Tolerance or Inch Trigger? Pick the Right Snow Service Level

December 22, 2025 · JRW Services LLC

Most snow contracts hinge on one line almost nobody reads closely: the service level. It sets when a crew shows up, how far they take it, and what you pay. Get it wrong and you either overpay for a lot nobody uses or carry the liability on a lot full of customers. Here is the plain-English version of the choice.

What a trigger actually means

The trigger is the snow depth that starts service. A two-inch trigger means crews plow once accumulation reaches two inches, and again at each two-inch interval. It is the standard for most lots because it balances cost and cleanliness. A lower trigger, one inch, means more passes, a cleaner lot, and a higher bill. A higher trigger saves money but lets snow build between visits.

Zero tolerance is a different animal

Zero tolerance, sometimes called bare pavement, is not just a lower trigger. It is a commitment to keep the surface clear and treated throughout the storm, plowing and salting continuously so the pavement stays down to blacktop. It costs more because it takes more passes, more salt, and crews staged on site. But for the right property it is the only responsible choice.

Which one fits your property

The honest answer depends on who is on your pavement and when.

• **Medical, senior living, and 24-hour operations.** Zero tolerance. People with canes, walkers, and wheelchairs are on that surface at 6 a.m., and the cost of a fall dwarfs the cost of an extra pass.
• **Retail, restaurants, and banks.** Usually a low one-inch trigger with priority on entrances. Customers judge you by the walk from their car, and a slushy lot sends them to the plaza that plowed.
• **Offices and industrial parks.** A two-inch trigger is often right. Traffic is predictable, it clusters at shift changes, and a clean lot by the time people arrive is enough.
• **Overflow lots and back storage.** A higher trigger, or plow-on-request. No reason to pay bare-pavement rates for pavement nobody walks.

Most properties are not one answer. The smart setup zones the site: bare pavement at the entrances and the accessible route, a standard trigger on the main lot, and a lighter level out back.

The trap in a per-push contract

On a per-push contract, the trigger is also what you get billed on, so a vague trigger is a billing dispute waiting to happen. Two inches measured where? Averaged across the lot, or at the drift by the building? A real contract says where and how snow is measured and what counts as a billable event. If yours does not, that is the conversation to have before you sign, not in February.

What to ask for

When you review your options, ask the contractor to put the service level in writing per zone, tell you the trigger and how it is measured, and spell out what treatment is included with each push. If they can map it to your actual property instead of quoting one number for the whole site, you are talking to someone who has done this before.
