Getting proper insurance to cover off premises liability for business use and cover your equipment is part of the cost of doing business. Any contractor who has made it past small homeowner handshake deals has to have it as any general contractors they’re subbed to or more sophisticated customers are going to require certificates of insurance as a condition of the contract.
For a small operator with no or few employees and a one or two machines, the cost varies widely depending on where you’re at and what insurer you’re with. I wouldn’t let insurance cost dissuade you at least until you’ve researched it in your area, build it in to your price, and see if you can compete with local pricing for similar services.
I have off premises coverage for both the equipment, including implements, and liability (non-business use) for about $400/year. That allows me to go to my Dad’s place, my brother’s place, church, friends’ places, etc. with the only caveat being I do NOT accept payment other than work in kind when I could use a return favor. That covers my equipment at actual cash value (not replacement cost) for theft, collision, rollover, fire, and a long list of other stuff plus $2.3 million liability coverage. Comparable coverage for business use varies in cost based on gross receipts and payroll. For a one man side business doing the type work you can do with a CUT type TLB, it would be about triple what I’m paying for non-business. If you’re forever hitting stuff underground or tearing up your equipment, you’ll be cancelled but the price set by each carrier pretty much is what it is. The above is applicable for NC only. Commercial coverages and prices vary widely because that market is much less regulated than more ubiquitous consumer products such as personal auto and homeowners, which is why you need to research with a competent local agent.
All that is to say proper insurance isn’t the death knell of a startup. You just need to clearly communicate exactly what you’re doing to a local agent who has commercial experience, preferably an independent agent who can shop coverage for you.
And no, I’m not an insurance agent. However, when there is a question on insurance coverage in NC, I don’t call my agent; my agent calls me.
