Requirements
Municipal permits are one thing. Contracts, property managers, and lenders are a different, often stricter, set of asks. Here's how they differ.
Plumbers run into insurance requirements from at least three separate directions, and they don't always agree with each other. There's the legal minimum set by your state or municipality to hold a license and pull permits โ covered in detail on our state-by-state requirements page. There's what a specific contract demands, which is frequently higher than the legal floor. And there's practical necessity โ coverage worth carrying even when nobody's formally asking for it.
General contractors writing you into a subcontract typically specify limits well above any state minimum โ often $1M per occurrence and $2M aggregate as a baseline, sometimes $2M/$4M on larger commercial jobs. They'll usually also require specific policy language: being named as additional insured, a waiver of subrogation, and on bigger projects, primary and non-contributory wording. None of that is a legal mandate anywhere โ it's a contractual one, and it's non-negotiable if you want the job.
Property management companies running a formal vendor program frequently exceed state minimums too, and often want the management company and the property ownership entity named separately as additional insureds โ two different legal names on one certificate. Our property manager vendor page goes deeper on what standing panel relationships specifically require versus a one-off job.
An angle that gets overlooked: homeowners financing a renovation through a home equity loan or a renovation-specific mortgage product sometimes can't get draw funds released to a contractor without that contractor first providing proof of insurance to the lender directly โ a requirement that has nothing to do with your state license and everything to do with how the homeowner's loan is structured. If you don't ask about this upfront, it can stall payment on an otherwise straightforward job.
Plenty of residential service calls never involve anyone asking for a certificate โ a homeowner calling about a clogged drain isn't running a vendor compliance program. But the underlying exposure doesn't disappear just because nobody asked for proof of it. See our cost page for what baseline coverage runs โ it's typically inexpensive enough that "nobody's making me" isn't a strong reason to skip it.
It's worth knowing that requirements aren't always locked in at signing. A GC can add a new insurance requirement partway through a multi-phase project if their own upstream client or lender changes terms, and a property manager can update panel-wide minimums when they bring on new ownership or a new compliance vendor. Building in a little coverage headroom above the bare minimum you were quoted at signing can save a scramble if the goalposts move mid-project.
Missing paperwork at the wrong moment costs more than the policy would have. A permit office can hold up your permit. A GC can pull the job and give it to the next bidder who had their COI ready. A property manager can drop you from the panel entirely. Our page on what's actually at stake covers what tends to happen when this paperwork isn't ready when it's asked for.

FAQ
No โ they're often different. State licensing sets a legal floor to hold your license; a GC's contract can and often does require higher limits and specific endorsements well beyond that floor.
Yes. Many permit offices check for active proof of insurance independently of your license status, and a lapsed policy can hold up a permit even for a fully licensed plumber.
Some do, particularly for loans with staged draw disbursements โ the lender can require proof of contractor insurance before releasing funds, separate from anything your state requires.
The contract wins for that job โ you'd need to carry whatever limit the contract specifies to take the work, regardless of what the legal minimum happens to be.
Not really, even absent a formal requirement โ the underlying water damage and completed-operations exposure exists on every job whether or not anyone asks to see proof of coverage.
