When your coverage falls short
If your unit is underinsured, the gap shows up at the worst moment, after a fire, a burst pipe, or a special assessment from the HOA. Say your HO-6 dwelling coverage is set at $40,000 but it actually costs $70,000 to rebuild your walls, floors, and cabinets after a loss. The insurer pays up to your limit, and you cover the rest yourself. The same thing happens with personal property and with loss assessment coverage, which pays your share of an HOA bill when the master policy doesn't cover the whole claim. Being underinsured usually isn't a choice someone made on purpose. It happens because the limit was set years ago, or copied from a neighbor's policy, or never adjusted after renovations. Check your declarations page against what it would actually cost to rebuild today.

A limit set years ago or copied from someone else's policy may not match what your unit costs to rebuild now. Compare quotes and check what coverage actually fits your condo.
How much HO-6 coverage does a unit actually need
There's no single number, because it depends on what the master policy covers and what your bylaws say about it. Some HOAs insure units as they were built, leaving you to cover upgrades like a renovated kitchen or finished basement. Others insure only bare walls, meaning your HO-6 has to cover everything from drywall in. Your HOA's governing documents and the master policy's certificate of insurance tell you which one applies, and that's the starting point for setting your own dwelling limit.
Once you know where the master policy stops, price out what it would cost to rebuild your unit's interior at today's labor and material rates, not what you paid for it or what it would sell for. A condo that sold for $250,000 might cost $90,000 to rebuild inside, or it might cost more, depending on finishes and square footage. Contractors and public adjusters can give rough per-square-foot estimates, and some insurers offer calculators for this during the quote process.
Personal property coverage needs the same kind of check. It's meant to cover what it would cost to replace your furniture, clothes, electronics, and everything else you own, not a guess carried over from a previous policy. Walk through your unit room by room and add up replacement cost, then compare that total to the limit on your declarations page.
Loss assessment coverage is worth sizing separately. It pays your share of a special assessment when the master policy's limit doesn't fully cover a shared loss, like roof damage after a storm or a liability judgment against the HOA. Many HO-6 policies include a modest amount by default, often $1,000 to $5,000, but HOAs with high deductibles on their master policy or buildings with a history of large claims can generate assessments well beyond that. Checking your HOA's master deductible and claims history helps you decide whether the default amount is enough or whether raising it is worth the small added cost.
Who pays when water comes from a neighbor's unit
Water damage is the claim that usually exposes how a building's coverage actually works, because the source of the water decides who pays first. If a pipe inside the building's shared walls fails, that's typically the master policy's problem, since it covers the building's systems. If the leak starts inside a neighbor's unit, from their washing machine hose or a bathtub left running, their HO-6 liability coverage is usually what responds, not yours.
Your own HO-6 still matters here no matter whose fault the leak was. It covers your unit's interior, your belongings, and your additional living expenses if you can't stay there while repairs happen, regardless of where the water started. You can file under your own policy and let the insurers sort out responsibility between themselves, which is often faster than waiting to find out whose fault it was before anything gets fixed.
Loss assessment coverage can come in a second way here too. If the water damage is extensive enough that the master policy's claim exceeds its limit, or if the building's deductible is high, the HOA may assess all owners for the shortfall, even owners whose units weren't touched by the water. That's separate from your own unit's damage. It's why loss assessment coverage and dwelling coverage are both worth checking after a shared-building loss, not just one or the other.
Townhomes complicate this further because ownership structures vary. Some townhome owners own the walls, roof, and land under their unit outright, closer to a single-family home, with no master policy involved at all. Others sit inside an HOA that insures shared structures like a condo building does. Checking your HOA's declaration and the deed itself clarifies which situation applies. A townhome that looks similar to a condo on the outside can carry a very different insurance setup underneath.
Before you go
Pull your declarations page and your HOA's certificate of insurance side by side. See where the master policy's coverage ends and check that your dwelling limit, personal property, and loss assessment amounts actually match what's left for you to cover.
