Master Policy or HO-6? Sorting Out Co-op and Condo Claims

In co-ops and condos, two or more policies often respond to the same loss. Here is how the master policy vs HO-6 split usually works and why it matters for valuation.

Two policies, one ceiling

When water pours through the ceiling of a Manhattan co-op or a Queens condo, the first question is not how much the damage costs but whose policy pays for which part. Understanding master policy vs HO-6 coverage is the key to getting a co-op or condo claim valued correctly, because the same wall may be split between the building’s insurer and yours.

The answer depends on three documents: the building’s master policy, your unit-owners (HO-6) policy, and the governing documents, which for a co-op is the proprietary lease and for a condo is the declaration and bylaws.

What the master policy usually covers

A co-op corporation or condo association buys a master policy for the building. Its reach varies:

  • Bare walls: the building covers structure and common elements, and the owner covers everything from the studs or plaster inward
  • Original specifications: the building covers the unit as originally built, and the owner covers upgrades and improvements
  • All-in: the building covers fixtures and finishes too, with owners covering personal property and their own improvements

Many New York co-op proprietary leases put responsibility for interior repairs on the shareholder, while the building handles structure, risers and common systems. Condo declarations draw their own lines. Ask the managing agent for the relevant sections and a copy of the master policy declarations.

What the HO-6 usually covers

A unit-owners policy typically covers the interior of your unit that the building does not, improvements you or prior owners made, personal property, loss of use and personal liability. Two often-overlooked parts matter in claims:

Loss assessment coverage

If the building’s master policy has a large deductible or a loss exceeds its limits, the board may levy an assessment on owners. Loss assessment coverage on an HO-6 may help pay your share, subject to its limit and terms.

Improvements and betterments

Renovated kitchens, custom millwork and upgraded flooring in pre-war apartments are often the most expensive items in a unit claim, and the most likely to fall to the owner’s policy.

Watch the master deductibleSome master policies carry deductibles large enough that the building passes small or mid-sized interior losses back to owners. How a deductible is allocated is set by the governing documents and board decisions, so read them before assuming who pays.

Where these claims stall

Co-op and condo claims tend to slow down for predictable reasons:

  • Neither insurer wants to pay the boundary items, such as plaster walls, ceilings or original flooring
  • The source of the leak is in another unit or a building riser, raising subrogation questions
  • The managing agent’s contractor and your contractor scope the job differently
  • Smoke or water migrated through several units in a multifamily building, making allocation complex

Our co-op and condo claim splitter can help you lay out which items belong to which policy before you talk to either adjuster.

How appraisal fits in

Appraisal works policy by policy. If your HO-6 carrier accepts its portion but undervalues it, you can generally pursue appraisal under your policy. If the dispute is with the building’s carrier, the board or association is usually the insured and controls that claim, so your role may be limited to pressing the board.

A panel can value items under one policy, but it generally cannot decide which policy is responsible. Questions about the proprietary lease, the declaration or allocation between insurers are legal questions; talk to a New York attorney if they are central to your dispute.

Valuing pre-war interiors

Many Manhattan and Brooklyn units still have plaster walls on wood or metal lath, original moldings, herringbone floors and older electrical and plumbing behind the walls. Estimates built around drywall and stock trim can understate the cost of restoring those finishes, and building alteration agreements may require licensed trades, insurance certificates and work-hour limits that add expense. A careful valuation accounts for those realities, and for whether your policy pays to match original materials. These are exactly the kinds of line-item differences an appraisal panel is suited to resolve.

Practical steps after a unit loss

  • Notify both the managing agent and your own carrier promptly, in writing
  • Request the master policy declarations and the relevant lease or declaration sections
  • Photograph everything before the building’s contractor opens walls
  • Keep a list of improvements, with dates and invoices if you have them
  • Get one estimate that separates building items from unit-owner items
