Owners and Contractors Protective (OCP) Liability
Also known as: OCP, OCP Liability, Owners and Contractors Protective Liability Coverage, CG 00 09
Owners and Contractors Protective (OCP) liability is a distinct, standalone commercial general liability policy — written on ISO form CG 00 09 — that is purchased for the benefit of a project owner or an upper-tier contractor but is arranged in connection with the work of one specifically designated contractor. The party being protected (the owner or GC) is the named insured, and coverage responds to bodily injury and property damage arising out of two things: the designated contractor's ongoing operations at the identified location, and the named insured's own liability arising from its general supervision of that contractor. It is essentially a compact premises-operations policy carved out for a single job and a single downstream contractor.
For a small-business buyer, OCP matters because it solves a control problem. When you require a subcontractor to name you as an additional insured, you are sharing their policy: their limits can be eroded by other claims, their carrier may be weak, the endorsement may be narrower than you think, and the policy can lapse without your knowledge. An OCP policy, by contrast, is your own contract with its own dedicated aggregate limit that no one else can spend, giving a property owner or general contractor certainty that supervisory-liability claims from a specific project are backstopped regardless of what the sub does. This is why OCP is frequently required in construction contracts alongside — not instead of — additional-insured and contractual liability requirements.
The critical nuance is scope. OCP coverage generally ends when the designated contractor's operations are completed: it does not cover the named insured's independent operations, work by other contractors, or products-completed-operations exposure after the job wraps — so it is not a substitute for the owner's own GL program or for a project-wide wrap-up (OCIP/CCIP) on larger builds. Buyers routinely confuse OCP with additional-insured status, but the two are legally different: additional-insured makes you an insured on someone else's policy, while OCP makes you the named insured on a separate policy you control. On multi-sub or long-duration projects a wrap-up or a robust additional-insured plus hold-harmless structure is usually more efficient; OCP shines for a single, discrete, higher-hazard operation where the owner wants dedicated, independent limits.
Real-world scenario
Meridian Property Group hired Callahan Steel Erectors to install structural framing for a new $4,200,000 medical office building in Columbus, Ohio. Rather than relying solely on being named an additional insured on Callahan's policy, Meridian's risk manager purchased an Owners and Contractors Protective (OCP) Liability policy naming Meridian as the insured for this specific job. The OCP policy carried a $1,000,000 per-occurrence limit and a $2,000,000 general aggregate, with an annual premium of $3,800 based on Callahan's estimated $950,000 subcontract cost.
Four months in, a steel beam being hoisted broke free and struck a visiting architect, causing a spinal injury. The injured party sued both Callahan and Meridian, alleging Meridian negligently failed to coordinate a safe site. Because the claim arose from Callahan's designated operations, Meridian's OCP policy responded directly. The insurer paid $610,000 in bodily-injury settlement, $95,000 in defense counsel fees, and $18,000 in expert-witness costs. Meridian's separate $10,000 deductible on its owner's practice program was never triggered, since the OCP has no deductible.
Had Meridian relied only on additional-insured status, Callahan's carrier could have rationed its shared $1,000,000 limit across multiple defendants, and a policy cancellation would have left Meridian exposed. The dedicated OCP gave Meridian its own limit and its own defense. Total premium of $3,800 protected against a claim that ultimately cost $723,000, and Meridian renewed OCP coverage on its next $2,750,000 project.
How it affects your premium
OCP premiums are relatively modest because coverage is narrow and job-specific, but several factors move the price:
- Subcontract cost of operations — The rating base is the total contract value of the designated contractor's work; a larger job means a higher premium.
- Type of work performed — Structural steel, excavation, and demolition rate far higher than interior finishing or landscaping because of severity potential.
- Limits selected — Moving from a $1,000,000 to a $2,000,000 per-occurrence limit increases premium, though not proportionally.
- Project duration — OCP policies are written for the length of the job; longer schedules extend the exposure period and the premium.
- Location and site hazards — Congested urban sites, proximity to occupied buildings, and public foot traffic raise the loss estimate.
- Occurrence vs. claims-made structure — OCP is typically written on an occurrence basis, which affects how the carrier prices the tail exposure.
- Whether a wrap-up already exists — On projects covered by a wrap-up (OCIP/CCIP), a separate OCP may be unnecessary, changing the buying decision entirely.
Common misconceptions
Myth: OCP coverage protects the contractor doing the work.
Reality: OCP protects the owner or general contractor who hires the designated contractor — not the contractor itself. The contractor still needs its own general liability policy for its operations.
Myth: If I'm named an additional insured on my subcontractor's policy, I don't need an OCP.
Reality: Additional-insured status shares the contractor's limits and can be diluted or eliminated by cancellation. An OCP gives you a dedicated limit and independent defense, which is why some owners buy both an additional insured endorsement and an OCP.
Myth: OCP covers the finished project after the contractor leaves.
Reality: OCP responds to liability arising from ongoing operations at the site; it generally does not cover completed operations once the designated work is done.
