Certificate of Insurance for Masons

Your COI Has to Satisfy Two Different Readers

A GC reading your certificate wants to know they're protected if your work causes a problem on their site. A municipal permitting office reading the same document is checking something different: whether you're authorized to do the structural work a building permit requires. Structural masonry is one of the few trades where both readers show up on the same job, which is exactly why your COI often has to do more work than it does for lighter trades.

Structural vs. Veneer Shows Up on the Page Itself

The description of operations on a mason's certificate frequently specifies structural versus veneer work, because some GC contracts and permitting offices scrutinize that distinction directly — a veneer-only certificate won't satisfy a structural permit requirement, and vice versa isn't automatically assumed either. See our GL page for how this distinction affects your underlying coverage. Getting this description right on the front end saves a rejected submission later.

What Actually Has to Be On the Certificate

• Named insured matching your business name exactly as licensed
• GL limits — per occurrence and aggregate, matched to what the specific contract requires
• Additional insured — the GC or property owner named specifically, or covered under a blanket endorsement
• Description of operations — structural, veneer, or both, worded to match what the certificate holder actually needs
• Certificate holder — the GC, property manager, or municipal office requesting it

The Permit Office Isn't Optional Paperwork

Some jurisdictions won't sign off on final inspection for structural masonry without a current certificate on file — a requirement that exists entirely separate from whatever your GC already has. Knowing this before you bid a permit-pulled job keeps the paperwork from stalling a project that's otherwise ready to close out.

Blanket Additional Insured Solves a Real Volume Problem

If you're bidding structural work across multiple GCs, adding each one individually gets tedious fast. A blanket additional insured endorsement automatically extends coverage to any GC or owner you work for, without a new endorsement request every time you win a bid.

What Commercial Contracts Typically Bundle Together

Beyond the baseline certificate, structural and commercial masonry contracts commonly require $2M/$4M limits (rather than the $1M/$2M that satisfies smaller jobs), a waiver of subrogation, and primary and non-contributory wording — three separate asks that are easier to build in from the start than to chase down endorsement by endorsement.

Your certificate is issued instantly the moment you bind coverage — ready to send to a GC, property owner, or permitting office the same day. See our cost breakdown for what coverage typically runs. If a job is starting tomorrow, same-day coverage is typically available so the paperwork doesn't hold up mobilization. If you're working as a sub rather than holding the prime contract, see our page on what coverage you need to carry as the 1099.
