By state and territory

Licensing is a state matter, so the requirement behind this cover changes at the border. These pages track the licence question in each jurisdiction.

What contracts commonly ask for

Principals and head contractors set their own insurance requirements, and those are frequently higher than a licence condition. The requirement that binds is the higher of the two, and both have to be read from the actual document.

What this cover costs

This site publishes no cost benchmark for this cover. A benchmark needs a real sample of documents, and none is published until the sample is large enough to compute a median honestly. A benchmark from a handful of policies is a guess with a decimal point.
