Liability Coverage

The City of Thornton doesn’t need to see proof of insurance for licensure as many cities do. This doesn’t mean you shouldn’t have insurance though. General liability cover will protect most aspects of your local building job. You can increase your coverage with an umbrella policy. Many contractors also use builder’s risk insurance to bridge coverage gaps.

If you employ other builders, workers compensation insurance is a vital investment. You may also like auto liability insurance to protect your work vehicle.

Best Equipment to Use

Thornton is known for its flat, easy-walking city and suburban streets. The flat plots of land it’s famous for make building a breeze. You can usually use standard manlifts and scissor lifts, rather than rough terrain ones. So long as the soil isn’t loose, boom lifts can operate well. Forklifts also don’t like soft Thornton soil.

Research the right licenses, permits, insurance, and equipment to make sure your next Thornton building job goes off without a hitch.
