Where your HOA's coverage ends and yours begins
The short answer: Your HOA's master policy generally insures the building and shared spaces; your HO-6 insures your unit's interior, your belongings, and your liability. Assuming the master policy has you fully covered is one of the most common and costly misunderstandings in condo ownership.
Think of it as two policies meeting at your unit's walls. The association's master policy handles the roof, the framing, the hallways, the pool, the parking lot — the parts everyone shares. Your HO-6 picks up where that leaves off: the flooring, cabinets, and fixtures inside your unit, your furniture and belongings, your personal liability if someone is hurt in your unit, and your additional living expenses if a covered loss forces you out for a while.
The reason this trips people up is that the exact meeting point isn't the same in every building. "Where the walls begin" sounds simple, but whether your original cabinets, flooring, and built-ins are the HOA's responsibility or yours depends entirely on what kind of master policy your association carries. And because HOAs facing their own rising premiums sometimes shift more responsibility onto owners by adopting narrower master policies, that line can move over time — often without owners noticing until a claim.
The three master-policy types (and why yours matters)
California condo master policies generally fall into one of three types. This is the single most useful thing to know about your building, because it determines how much interior coverage your HO-6 needs to carry. It's also, unsurprisingly, the most common source of coverage disputes after a water-damage claim.
| Master policy type | What the HOA covers | What you insure with your HO-6 |
|---|---|---|
| Bare walls (least common) | Structural shell only | Everything from the drywall inward — flooring, cabinets, fixtures, plus personal property |
| Walls-in / original specs (most common) | Structure plus original fixtures | Your upgrades and improvements, plus personal property |
| All-in / all-inclusive | Everything inside, including improvements | Mainly personal property and loss assessment |
The practical stakes are real. If you're in a bare walls building, you're effectively responsible for insuring the entire interior finish — and in 2026, rebuilding a condo interior costs meaningfully more than it used to, with condo work often running higher per square foot than a comparable house because of elevators, HOA work-hour rules, and access constraints. Underinsuring your interior coverage (Coverage A) is the most common mistake condo owners make. Even in an all-in building, it's often wise to carry some interior coverage, because it can help bridge the master policy's deductible after a shared loss.
What an HO-6 policy actually covers
Beyond the interior "dwelling" coverage we just talked about, a well-built HO-6 has a few other moving parts. Here's what each one does.
- Dwelling (Coverage A) — your unit's interior, sized to your master-policy type. The piece owners most often set too low.
- Personal property — your furniture, electronics, clothing, and belongings, whether they're in your unit or with you elsewhere.
- Personal liability — legal defense and damages if someone is injured in your unit or you're held responsible for damage, including to a neighboring unit.
- Loss of use — extra living costs if a covered loss makes your unit temporarily unlivable.
- Loss assessment — your share of certain HOA assessments after a covered loss. More on this next, because it's the one people overlook.
One California-specific note on liability: water damage is the claim that most often crosses unit lines here, and responsibility can hinge on where the water came from and who owns the plumbing involved. That's part of why carrying solid personal liability and interior coverage matters — a leak from your unit into the one below can become your problem quickly.
Loss assessment: the coverage owners overlook
The short answer: Loss assessment coverage pays your share when the HOA charges unit owners for a covered loss that goes past the master policy's limit or deductible. With California HOA deductibles often running $25,000 to $100,000 or more, this is the coverage that protects you from a five-figure surprise bill.
Here's the scenario it's built for. A fire or major water event damages the building. The master policy responds, but its deductible is, say, $50,000 — and the association spreads that cost across unit owners as a special assessment. Suddenly you owe several thousand dollars you didn't budget for. Loss assessment coverage on your HO-6 is designed to step in and pay your share, up to your policy's limit.
The catch is that many policies come with only a small default loss assessment limit that hasn't kept pace with how large master-policy deductibles have grown. Recent California events have shown just how high these assessments can climb after a major disaster. It's worth checking your loss assessment limit against your HOA's actual master-policy deductible, and raising it if there's a gap — it's usually inexpensive relative to the protection it buys.
Earthquake and the other gaps to plan for
A couple of things sit outside a standard HO-6, and in California they're worth planning for rather than discovering after the fact.
Earthquake. A standard HO-6 doesn't include earthquake coverage, and the HOA's master policy may or may not cover the building for quake damage. Even where the association does carry it on the structure, your interior finishes, personal property, and living expenses generally aren't covered without your own earthquake policy. California condo owners can add this through the California Earthquake Authority, which offers condo-specific coverage, or a private insurer. In the Bay Area especially, it's a gap worth a deliberate decision rather than a default.
Flood. Like most property policies, an HO-6 generally excludes flood, which is covered separately. Depending on where your building sits, this may or may not be a live concern, but it's worth confirming.
The master-policy mismatch. The most avoidable gap of all is simply not knowing your master-policy type, and buying an HO-6 that either overlaps it (paying twice) or underlaps it (leaving a hole). Matching your HO-6 to your specific building is the whole game, and it's where an agent who'll actually read your documents earns their keep.
The bottom line
Condo insurance in California comes down to one idea: your HO-6 has to fit the specific building you live in. Find out which of the three master-policy types your HOA carries, size your interior coverage to match, carry enough loss assessment coverage to survive a big HOA deductible, and make a deliberate call on earthquake. Get those right and you've closed the gaps that catch most owners.
If you're not sure where your HOA's coverage stops, bring us your master-policy summary and your CC&Rs along with your current HO-6, and we'll read them together. We'll show you exactly where the line falls in your building, flag any overlap or gap, and size your policy to fit — and because we work with more than one carrier, if your building or situation is harder to place, we can go looking rather than shrug.
California condo insurance FAQ
Do I need condo insurance if my HOA has a master policy?
In most cases, yes. Your HOA's master policy generally covers the building structure and common areas, not the inside of your unit, your personal belongings, or your personal liability. An HO-6 condo policy is designed to cover those gaps. Many lenders also require an HO-6 as a condition of a condo mortgage, and relying on the master policy alone tends to leave owners exposed after a loss.
What is an HO-6 policy?
HO-6 is the standard condo or townhome insurance policy for an individual unit owner. It typically covers the interior of your unit from the walls in, your personal property, your personal liability, additional living expenses if you're displaced, and loss assessment coverage for your share of certain HOA charges. How much interior coverage you need depends on what your HOA's master policy already includes.
What is loss assessment coverage and why does it matter in California?
Loss assessment coverage pays your share when the HOA levies a special assessment on unit owners after a covered loss that exceeds the master policy's limits or deductible. Master-policy deductibles on California associations can run from roughly $25,000 to $100,000 or more, and that cost can be passed to owners. Loss assessment coverage is the main protection an individual owner has against that kind of surprise bill, which is why it's worth sizing carefully rather than leaving at a token amount.
What are the three types of HOA master policy?
Master policies generally fall into three types. Bare walls covers only the structural shell, so the owner insures everything from the drywall inward. Walls-in, sometimes called original specifications, is the most common and covers the structure plus original fixtures, leaving upgrades and personal property to the owner. All-in, or all-inclusive, covers everything inside the unit including improvements, so the owner mainly needs personal property and loss assessment coverage. Your association's governing documents define which type applies to you.
Does condo insurance cover earthquake damage in California?
No. A standard HO-6 policy doesn't include earthquake coverage, and neither does the HOA master policy in many cases. California condo owners can add earthquake coverage through the California Earthquake Authority, which offers condo-specific policies, or through a private insurer. Even when the HOA carries earthquake coverage on the building, your interior, personal property, and living expenses generally aren't covered without your own earthquake policy.
