Quick Answer
What’s the difference between HO-6 condo insurance and a building’s master policy?
The building’s master or AOAO policy generally covers the structure itself and the common areas — the roof, the lobby, the pool, the exterior walls. Your individual HO-6 policy covers what’s inside your unit: interior finishes, your personal belongings, loss assessment, and personal liability. Many new Oahu condo buyers assume the master policy handles everything and skip HO-6 coverage entirely, which can leave a real gap if something happens inside their own four walls.

This is one of the most common questions Aksana walks first-time Oahu condo buyers through, usually right after closing, when it’s already too late to ask “wait, do I need my own policy too?” The short answer is almost always yes. Here’s the plain-language version of why, and what each policy is actually built to do. This is general education, not insurance advice — always confirm your specific coverage with a licensed insurance agent and your building’s AOAO board.
What the Master Policy Actually Covers
Every condo building on Oahu carries a master insurance policy, purchased and maintained by the Association of Apartment Owners (AOAO) and paid for out of association fees. This policy is built around the shared parts of the property: the building’s structure, the roof, the exterior walls, elevators, hallways, lobbies, and amenities like a pool or fitness room. If a hurricane damages the roof, or a fire starts in a shared stairwell, the master policy is generally what responds first.
How much of the interior of an individual unit the master policy reaches varies by building and by policy type. Some master policies are written on an “all-in” or “single entity” basis that includes original fixtures inside each unit — the builder-grade cabinets, countertops, and flooring as they existed when the building was constructed. Others are written on a “bare walls” basis that stops at the unfinished interior surface of the unit’s walls. This distinction matters enormously and is exactly the kind of detail a buyer should ask about directly, in writing, from the AOAO board or property manager, before assuming anything.
What Your HO-6 Policy Is Built to Cover
An HO-6 policy, sometimes called a condo owner’s policy or a walls-in policy, is the individual coverage you purchase yourself, separate from the building’s master policy. It’s generally built around four things:
- Interior improvements and betterments — upgrades you’ve made beyond the unit’s original builder-grade condition, like new flooring, custom cabinetry, or a renovated bathroom.
- Personal property — furniture, electronics, clothing, and everything else you own inside the unit.
- Loss assessment coverage — if the AOAO issues a special assessment to cover a shared loss that exceeds the master policy’s limits, this piece of your HO-6 can help cover your share.
- Personal liability — protection if someone is injured inside your unit, or if damage from your unit affects a neighboring one, like a water leak that damages the unit below.
Without an HO-6 policy, all four of those categories are generally sitting entirely exposed, regardless of how comprehensive the building’s master policy is. The master policy was never designed to reach that far.
The Gap Most New Buyers Don’t See Coming
The scenario that catches people off guard almost always involves water. A pipe bursts inside a unit two floors up, and water works its way down through several units below it. The master policy may address damage to the building’s shared plumbing and structure, but the interior finishes, flooring, and personal belongings inside each affected unit are a different question entirely — and if any of those owners skipped their HO-6 policy, they’re paying for those repairs and replacements out of pocket.
The other common gap is loss assessment. If an AOAO’s master policy doesn’t fully cover a major shared loss — storm damage to the roof and exterior that exceeds the policy’s limits, for example — the association can issue a special assessment, billing every owner a share of the shortfall. A loss assessment provision inside an HO-6 policy is specifically built to help absorb that bill. Owners without it are exposed to a special assessment with no insurance backstop at all.
There’s a version of this gap that catches buyers even when the master policy itself is solid: many Oahu AOAO master policies now carry a deductible of $10,000, $25,000, or more before the policy pays anything on a claim, and that deductible does not disappear once a claim is filed. Depending on the building’s governing documents, it typically gets billed to the unit where the loss originated, or spread across all owners as a special assessment. The catch is that a standard HO-6 policy usually ships with only about $2,000 of loss assessment coverage by default, which is nowhere near enough to absorb a $10,000-plus master policy deductible. Ask the AOAO what the master policy’s deductible actually is, then raise your own HO-6 loss assessment limit to match it — that increase is typically inexpensive relative to the exposure it closes.
What to Actually Ask Before You Close
Before closing on any Oahu condo, ask the AOAO or property manager for a copy of the master policy’s declarations page and its specific coverage basis — “all-in,” “single entity,” or “bare walls.” That one document tells you exactly where the building’s coverage stops and where your own HO-6 policy needs to begin. Your lender will typically require an HO-6 policy as a condition of the loan regardless, but even a buyer paying cash should treat it as effectively mandatory, not optional. If you’re evaluating a CPR or multi-unit property specifically, see What Is a CPR Property on Oahu, and Why Do Some Sell Better Than Others? for how that structure adds its own layer to this question.
Master Policy vs. HO-6: Who Covers What
| What’s at Risk | Master / AOAO Policy | Individual HO-6 Policy |
|---|---|---|
| Building structure, roof, exterior walls | Generally yes | No |
| Common areas (lobby, pool, elevators) | Generally yes | No |
| Interior finishes/upgrades inside your unit | Depends on policy basis — confirm with AOAO | Generally yes (improvements & betterments) |
| Personal belongings (furniture, electronics) | No | Generally yes |
| Special assessment for a shared shortfall | No (this IS the shortfall) | Generally yes (loss assessment coverage) |
| Personal liability inside your unit | No | Generally yes |
What this tells me as the numbers agent for Oahu buyers: the master policy and your HO-6 are built to meet in the middle, not overlap — the real risk isn’t which one is “better,” it’s the buyer who assumes the master policy reaches further than it actually does.

Frequently Asked Questions
Does my condo’s master policy cover the inside of my unit?
It depends on the building. Some master policies cover original builder-grade interior finishes (“all-in” or “single entity” coverage); others stop at the unfinished interior wall surface (“bare walls”). Ask your AOAO or property manager which basis your building uses before assuming either way.
Is HO-6 insurance required, or optional?
Most lenders require it as a condition of financing a condo purchase. Even buyers paying cash should treat it as effectively mandatory, since personal property, upgrades, liability, and loss assessment exposure are generally not covered by the master policy at all.
What is loss assessment coverage, and why does it matter?
If the AOAO’s master policy doesn’t fully cover a shared loss, the association can bill every owner a share of the shortfall through a special assessment. Loss assessment coverage inside an HO-6 policy is designed to help absorb that bill.
What if the building’s master policy has a high deductible?
Many Oahu condo master policies carry deductibles of $10,000 or more, and some run much higher, especially for hurricane and water-damage claims. That deductible is real money that gets passed to owners, either billed to the unit where the loss started or spread across the association as a special assessment. A standard HO-6 policy typically includes only about $2,000 of loss assessment coverage by default, so ask the AOAO what the master policy’s deductible is and raise your own loss assessment limit to match it.
What happens if a leak in my unit damages my neighbor’s unit below?
This is exactly the kind of scenario personal liability coverage inside an HO-6 policy is built to address. Without it, you could be personally responsible for the cost of your neighbor’s repairs.
Is this article insurance advice?
No. This is general education on how condo insurance is typically structured in Hawaii. For your specific building and policy, talk to a licensed insurance agent and your AOAO board.
Where This Leaves You
Before you close on a condo, or if you already own one and have never checked, get a copy of your building’s master policy declarations and confirm its coverage basis, then make sure your own HO-6 policy is built to cover the gap. It’s a short conversation that closes a real exposure.
