Contractor Insurance & Bonding Explained: Coverage, Bonds & Costs

Updated 2026-09-23 · Sources: Federal (SBA) + state regulators + insurance-industry ranges

Insurance and bonding are the two things a client, a general contractor, or a licensing board will almost always ask you to show — and they're constantly confused for each other.

Where this comes from. The SBA bond and insurance overviews are federal; required coverages and limits are set by each state; and the cost ranges are private insurance-industry figures, not government data — ballparks to sanity-check a quote.

Insurance protects you, a bond protects your client

Insurance you'll actually need

Confirm requirements with your state's department of insurance and licensing board.

Bonds you'll run into

The SBA Surety Bond Guarantee Program

The one most small contractors miss. If you can't get bonded commercially, the SBA guarantees a portion of your bid, performance, and payment bonds so a surety will bond you.

What it costs (ballpark)

Rough industry ranges, not quotes — your real number depends on trade, state, payroll, and credit.

WhatApproximate annual cost
Solo painter/handyman — total insurance~$2,000–$5,000
Roofer with employees — total insurance~$8,000–$25,000+
License / permit bond (good credit)~$100–$500

The biggest driver is workers' comp, which scales with payroll and trade risk.

The caveat: the numbers are set by others

Your required coverages and limits come from your state, each GC's contract (often higher than the state minimum), and the obligee on a bonded job. Two terms GCs use: a Certificate of Insurance (COI) (proof of coverage) and Additional Insured (adding the GC to your GL policy). Read every contract's insurance and bond terms before signing, and keep your COI current.
