CityvettedLiens, insurance, and bonds in plain English
Mechanic's liens, lien waivers, and what a contractor's bond actually does for you, stripped of the jargon.
Three words get thrown around in every contractor pitch, and most homeowners nod along without really knowing what any of them mean. Licensed. Bonded. Insured. They are not interchangeable, and only one of them is mostly there to protect you. Sort out what each actually does and you will read a quote very differently.
- A mechanic's lien lets unpaid workers and suppliers put a claim on your house, even if you paid the contractor.
- Insurance protects against accidents and injuries. It is the one that shields you most directly.
- A bond is a small financial backstop, useful but often capped low.
- Always verify coverage with the issuing company, not the contractor's word.
Liens: the risk hiding behind your own payment
Here is the part that surprises people. If you pay your general contractor in full, but the contractor never pays the drywall supplier or a subcontractor, that unpaid party can file a mechanic's lien against your property. The debt was not yours, but the lien attaches to your house. You can end up paying twice, or fighting a cloud on your title when you try to sell or refinance.
The defense is paperwork. On any job with subs and suppliers, collect lien waivers as you go. A waiver is a signed statement that the person has been paid for work through a certain date and gives up the right to lien. Conditional waivers take effect once a payment clears. Unconditional waivers apply right away, so save those for after the check is cashed. Tie waivers to your draw schedule and the risk mostly disappears.
"You can pay your contractor every dollar you owe and still get hit with a lien for someone they stiffed. Waivers are how you close that door."
to Priya Anand, Deputy EditorInsurance: the coverage that actually protects you
If you remember one thing, remember this. Insurance is the protection that matters most when something goes wrong on your property. There are two kinds you care about, and they cover very different events. General liability handles property damage and injuries to others. Workers' compensation handles injuries to the contractor's own crew.
Why does the crew's injury become your concern? Because if a worker falls off your roof and the contractor carries no comp, the injured worker can come after the homeowner. Verifying both policies is not paranoia. It is the difference between a bad day on the job and a lawsuit with your name on it.

Bonds: a backstop, not a guarantee
A surety bond is a three-party arrangement. The contractor buys it, a surety company stands behind it, and you can make a claim against it if the contractor breaks the rules of their license. Many states require a license bond to operate. It is genuinely useful, but read the number. A 15,000 dollar bond does not go far on a 90,000 dollar remodel gone wrong, and claims can be slow.
Think of bonding as a floor, not a ceiling. It tells you the contractor cleared a basic financial bar to get licensed, and it gives you one more avenue if things fall apart. It does not replace insurance, and it does not protect you from liens. Treat all three as separate layers.
- Get the certificate of insurance.
Ask for a COI naming both general liability and workers' comp, with policy numbers and dates.
- Call the insurer, not the contractor.
Confirm the policy is active and the coverage limits match what you were told.
- Check the license and bond.
Most states have an online license lookup that shows bond status and any complaints.
- Build waivers into the schedule.
No draw goes out without a signed lien waiver covering the prior phase.
Putting it together
Licensed means the contractor met the state's bar to legally do the work. Bonded means there is a modest financial backstop tied to that license. Insured means accidents and injuries are covered by a policy, not by your bank account. The first proves eligibility, the second offers a small cushion, and the third does the real protecting.
A contractor who gets quietly annoyed when you ask to verify any of this is telling you something. The good ones expect the question and have the documents ready. It is your home and, when the paperwork goes sideways, your money. Spend the twenty minutes.
Cityvetted will not list a home-service business that cannot show active general liability and, where the crew is employed, workers' comp. We also flag whether a state license and bond check out, because the verifiable basics are the baseline every homeowner deserves.
