Your building carries a master insurance policy — but it wasn’t written to protect your renovated kitchen, your belongings, or your share of the deductible when disaster strikes. That’s your policy’s job.
Condo and co-op insurance (the HO-6 policy) fills the gap between your building’s master policy and everything you’re personally responsible for: your unit’s interior, your belongings, your liability, and — critically — your share of building deductibles and assessments. The single most important step is reading the master policy first, because it dictates exactly where your coverage needs to begin.
When you own a condo or co-op, you don’t insure a whole building — the association or corporation does that through a master policy covering the structure, roof, hallways, elevators, and common areas. Your policy, the HO-6 unit-owners form, covers everything the master policy doesn’t: the interior of your unit, your personal property, your liability, and your living expenses if the unit becomes uninhabitable.
The condo/co-op distinction matters more than most owners realize:
Condo owners hold a deed to their unit. The condo association’s bylaws define which parts of the unit are yours to insure — often everything from the drywall inward.
Co-op owners don’t technically own real estate at all — they own shares in a corporation plus a proprietary lease granting the right to occupy the unit. The corporation’s policy covers the building, but the proprietary lease typically makes shareholders responsible for their unit’s interior, alterations, and improvements — and most New York co-op boards now require proof of an HO-6 policy as a condition of the lease or before approving a purchase or renovation.
Master policies come in three flavors, and your HO-6 dwelling limit should be built around which one your building carries:
| Master policy type | What the building covers | What you must cover |
|---|---|---|
| Bare walls | Structure and common elements only — nothing inside your unit's walls | Everything inside: flooring, cabinets, fixtures, countertops, even drywall |
| Single entity ("walls-in") | The unit's original fixtures and finishes as first built | Any upgrades and improvements — the renovated kitchen, new floors, custom built-ins |
| All-in | Structure plus unit interiors, including improvements | Personal property, liability, loss of use, and deductible/assessment exposure |
Found in the association’s bylaws or the co-op’s proprietary lease and master policy declarations — documents worth reviewing with your broker before setting limits.
Walls-in property you’re responsible for — flooring, cabinetry, fixtures, built-ins — plus betterments and improvements: every dollar of renovation you’ve put into the unit.
Furniture, clothing, electronics, and household goods — at home or away from it — against perils like fire, theft, vandalism, and sudden water damage.
Steps into the shoes of an at-fault driver who has no insurance, too little insurance, or flees the scene — covering your injuries when the responsible party can’t.
Hotel, temporary rent, and added living costs if a covered loss forces you out of the unit during repairs.
Your share when the association assesses unit owners after a covered loss — because the master policy limit fell short, or to recover its deductible.
No-fault medical coverage for guests injured in your unit, paid without lawsuits or blame.
Owners often assume “the building has insurance” means they’re protected. But in a bare-walls building, a fire can leave you rebuilding an entire interior out of pocket; even in a walls-in building, your renovations aren’t covered. In a market where a modest kitchen and bath renovation runs well into six figures, an HO-6 with the wrong dwelling limit is barely better than none.
Building master policies increasingly carry deductibles of $25,000, $50,000, or more, especially for water damage. When a loss originates in or affects your unit, the association can pass that deductible to you — and after a building-wide loss, boards routinely assess all owners for the shortfall. Loss assessment coverage is the inexpensive line item that absorbs these hits, and it’s the most commonly underbought coverage on unit-owner policies.
In a house, your burst pipe damages your house. In a condo or co-op, your washing machine hose can damage three units below you — making the liability portion of an HO-6 far more likely to be used than most owners expect. It works in reverse, too: your policy repairs your unit when the damage comes from above, then your carrier pursues the responsible party.
Mortgage lenders on condos require an HO-6. Co-op boards increasingly mandate coverage — with specific liability minimums — through the proprietary lease or house rules, and require certificates before approving renovations. Coverage isn’t just protection; it’s a condition of ownership.
Loss assessment only follows covered perils. If the board assesses owners for a new roof, an elevator upgrade, or flood damage the master policy excluded, your loss assessment coverage doesn’t respond — it only pays when the underlying cause is a peril your policy covers. Assessments for maintenance and capital improvements are simply a cost of ownership.
Gradual water damage is a maintenance problem, not a claim. The slow leak behind the shower wall that finally shows itself is typically excluded on every policy in the building — one more reason unit-to-unit water disputes get complicated, and why documentation and prompt reporting matter.
Renting your unit changes everything. Long-term tenants call for a landlord (dwelling-fire) policy rather than a standard HO-6, and short-term rental activity is commonly excluded outright — in addition to whatever your board or lease has to say about it.
High-value unit? Luxury condos and co-ops with significant renovations, art, or wine collections outgrow standard HO-6 sublimits. High-value unit-owner programs offer cash-settlement options, generous improvement limits, and broader valuables coverage — part of GCI’s personal lines practice alongside umbrella and collectibles coverage.
Group Coverage, Inc. reviews your association’s master policy or proprietary lease alongside your unit coverage — setting dwelling, improvement, and loss assessment limits where the building’s coverage actually ends, then shopping the market for the best fit.
This article is for general educational purposes. Coverage terms, limits, and exclusions vary by policy form, carrier, state, and your association’s governing documents.
