If you own a condo or townhouse in California, you probably know your HOA has a master insurance policy. You may even know you need your own condo policy on top of it.
What most condo owners don't fully understand is the gap between those two policies, and how a routine claim can suddenly become tens of thousands of dollars out of pocket if you're not covered for it.
How condo insurance works (the basics)
The HOA master policy
Your homeowners association carries a master policy that covers the building structure and common areas. The exact coverage depends on the type of master policy your association has. There are three common types:
- Bare walls coverage: covers the structure to the unfinished interior wall surfaces. Drywall, flooring, fixtures, and improvements inside your unit are NOT covered by the master.
- Single entity coverage: covers original interior fixtures and finishes (the developer-installed stuff) but not improvements you've made.
- All-in coverage: covers everything inside the unit at the time of purchase, including upgrades. This is the broadest type, but it's also the least common.
Your condo (HO-6) policy
This is the policy you buy individually. It covers what the master policy doesn't, plus your personal belongings and liability.
Standard HO-6 policies include:
- Interior walls, flooring, cabinetry, fixtures (depending on what the master covers)
- Improvements and upgrades (granite countertops, hardwood floors, custom built-ins)
- Personal property
- Personal liability for things that happen inside your unit
- Loss of use if your unit becomes uninhabitable
The gap that catches condo owners off guard
Here's what most condo owners don't understand: the master policy almost always has a deductible. And often a big one.
How HOA deductibles work
If something covered by the master policy is damaged (the building structure, common areas, etc.), the HOA files a claim. The master policy pays after its deductible is met.
In California, master policy deductibles are commonly $5,000 to $25,000. Some are higher, especially for water damage or earthquake events. Some are as high as $50,000 or $100,000.
Who pays the deductible?
This is where it gets dangerous. Many California HOAs allocate the deductible to the unit owner whose unit caused the damage.
If a pipe in your unit bursts and damages three units below yours, your HOA may file a claim for the building damage. Their master deductible is $25,000. The HOA's bylaws say the unit owner whose pipe failed is responsible for the deductible.
Now you owe $25,000 to the HOA, and your condo policy may or may not pay it.
Loss assessment coverage: the gap-filler most owners don't have
Loss assessment is the part of your condo policy that pays HOA assessments levied against you for covered losses.
Standard HO-6 policies often include $1,000 to $5,000 of loss assessment coverage by default. That's nowhere near enough for modern HOA deductibles.
How much loss assessment coverage you should have
Match it to your HOA's master deductible. If the master has a $25,000 deductible, you should carry at least $25,000 in loss assessment coverage. $50,000 is often safer.
Cost: typically $25 to $75 per year per $50,000 of loss assessment coverage. It's the cheapest way to fill the gap.
Other gaps you should know about
Water damage limits and exclusions
Master policies often have stricter water damage limits than other coverages. A leaking dishwasher, washing machine, or water heater can cause significant damage to your unit and units below.
Make sure your condo policy includes water damage from common sources, and check for sub-limits on flooded units.
Sewer backup
Standard condo policies often exclude sewer backup unless you specifically add it. Worth $50 to $100 a year for the endorsement, especially in older buildings.
Mold remediation
If a covered water loss causes mold, remediation can be expensive. Many policies have mold sub-limits as low as $5,000. Higher mold limits are usually available as endorsements.
Building improvements
If you've upgraded the kitchen, redone the floors, added custom built-ins, or made any improvements since you bought, you need to make sure your condo policy reflects the cost to replace those upgrades. The master policy will not.
Common mistake: owner buys the unit at $400,000 with builder-grade finishes, then spends $80,000 on upgrades over a few years, but never increases the dwelling coverage on their condo policy. After a fire, they get $X for the original finishes but nothing for the $80,000 of upgrades.
The questions to ask your HOA
Most condo owners have never read their HOA's master policy. Here are the four questions that tell you what kind of master coverage you have:
- What type of master policy do we have? (Bare walls, single entity, or all-in)
- What is the master deductible for water damage, fire, and earthquake?
- Does the HOA pass deductibles through to unit owners? Under what conditions?
- Are there any special assessments planned, and what's the financial reserve status?
If your HOA can't answer those clearly, that's worth knowing too.
California-specific concerns
Earthquake coverage
Most master policies exclude earthquake damage entirely. Some HOAs carry separate earthquake coverage; many don't. If your HOA doesn't, your condo policy probably doesn't either, and your unit is exposed.
Adding earthquake coverage to your condo policy is a separate conversation. The California Earthquake Authority has condo-specific products.
Wildfire and master policy non-renewals
Some California condo associations in high-fire-risk areas have had master policies non-renewed or moved to FAIR Plan coverage. If your HOA is in that situation, your condo policy may need adjusting too.
Bottom line
Condo insurance is the most common type of policy where the gap between what people think is covered and what actually is covered ends up costing them. The fix is usually simple: add adequate loss assessment coverage, increase your dwelling coverage to reflect any improvements, and confirm the relationship between your policy and the HOA's master.
If you've owned your condo for more than three years and haven't had your policy reviewed in light of your HOA's master, it's worth a 15-minute conversation. We do this for California condo owners regularly and almost always find a gap to close.
