Owners and Contractors Protective (OCP) Liability Insurance
Owners and contractors protective (OCP) liability insurance is a standalone policy that protects a designated party, most often the project owner, in that party’s own name for one project. It covers liability arising from the named contractor’s operations and the owner’s general supervision of that work, giving direct coverage rather than additional-insured status on the contractor’s policy.
Owners and contractors protective liability, usually shortened to OCP, is a standalone general liability policy that protects a designated party, most often the project owner, in that party’s own name. It is written for one project and it gives you direct coverage, which is different from being listed as an additional insured on someone else’s policy.
What does OCP liability insurance cover?
- Liability arising from the operations of the named contractor performed for you on the project.
- Liability arising from your own general supervision of that contractor’s work.
- Direct protection, because you are the named insured (the protected party), not a party added to the contractor’s policy.
Who needs it? Project owners who want coverage in their own name rather than relying solely on additional-insured status. Owners engaging a single primary contractor on a defined project. Situations where a contract calls specifically for OCP coverage. And parties who want a clean, project-specific set of limits for their supervision exposure.
Because you are the named insured, an OCP policy can respond directly to a covered claim rather than depending on how a contractor’s carrier interprets additional-insured wording. In California, where construction-defect and completed-operations exposure runs long, owners often value having their own project record and their own limits. OCP is typically written per project, so it usually needs to be arranged before work begins.
How we help: We help you decide whether OCP, additional-insured status, or a combination fits your project, and we make sure the coverage lines up with what your contract requires.
OCP liability insurance in California, explained
Who buys an OCP policy, and who does it protect?
The contractor buys it and pays for it. The project owner is the named insured, and the contractor is not an insured at all. That is the arrangement the form is built for. The ISO Owners and Contractors Protective Liability Coverage Form (CG 00 09, current edition 04 13) names a designated contractor and a designated location in its declarations. It covers the owner’s liability for bodily injury and property damage arising out of that contractor’s operations at that location, plus the owner’s own acts or omissions in general supervision of the work. The contractor’s own liability stays on the contractor’s own general liability policy, which is why OCP is bought alongside it and not instead of it.
Why would an owner want OCP rather than additional insured status?
Four reasons, and they all come from being the named insured on a policy of your own. The limits are yours alone, not shared with every other claim against the contractor that year. The coverage is primary and does not seek contribution from your own liability policy. Notice of cancellation comes to you, because you are the first named insured, and only you can cancel it. And the insuring agreement covers liability that arises out of the contractor’s operations, without the “caused, in whole or in part, by” limitation that the current ISO additional insured endorsements carry. Additional insured status is cheaper and broader in one respect, since it can include completed operations; OCP is narrower and cleaner. Some California public entities and larger owners list it among the coverages they may require. Los Angeles County’s contract insurance standards, for example, include owners and contractors protective liability under coverages that may be required for specialized exposures. It is not a default on most public work, and Caltrans, for one, specifies additional insured status instead.
What does OCP not cover?
Completed operations. Coverage ends at the earlier of two events. The first is all the contractor’s work on the project (other than service, maintenance or repairs) being completed. The second is the part of the work the injury arises from being put to its intended use by anyone other than another contractor on the same project. A claim two years after the ribbon-cutting is not an OCP claim. It also excludes the owner’s own acts beyond general supervision, so an owner who directs the means and methods of the work, or performs part of it, is outside the form for that conduct. Nothing in it covers the building, the materials, or the contractor.
How is an OCP policy written and priced?
Per project, with a term that runs from the start of the work to its completion, and with its own each-occurrence and aggregate limits. A $1,000,000 per occurrence and $2,000,000 aggregate structure is typical, and higher limits are available where the contract demands them. The premium is a rate applied to the contract price for the designated contractor’s work, so a larger job costs more to protect. The contractor pays it and passes the cost through the bid, and the premium refund on early cancellation goes back to the contractor. What the owner supplies is the exact legal entity to be named, the location, and the contract value.
When does OCP make sense on a California project?
When the owner wants a policy that responds to its own exposure without depending on the contractor’s loss history, aggregate or carrier. When a lender or public agency writes it into the contract. And when the contractor’s additional insured endorsement, read carefully, does not give the owner what the contract promised. It is common on public and institutional work and on projects where the owner has no operations of its own beyond supervising the job. For a contractor, it is a line item to price into the bid rather than a coverage to resist; the alternative is usually a broader additional insured demand.
How do you get an OCP quote from us?
Start a business insurance quote and send us the contract’s insurance exhibit, the owner’s exact legal name, the project address, and the contract value. OCP is a specialty placement. Some carriers issue it quickly on a contractor they already insure; others need the underwriter’s review, or the project has to be placed in a wholesale market, and those take longer. Either way you know before you decide. The mechanics of additional insured endorsements, and why a certificate cannot create one, are in certificate of insurance in California; what a contractor’s own program should contain is in what insurance contractors need.
