Who Owns the Walls in a Condo?
It depends on your condo association's governing documents, which split ownership at either the unfinished or finished wall surfaces.

Your HOA's declaration sets the line, and it falls one of two ways. Under a "bare walls" approach, the master policy covers only the building's structure, the studs and the concrete, and your HO-6 has to cover everything inward from there, including drywall, flooring, cabinets, and fixtures. Under "single entity" or "all-in" coverage, the master policy extends to fixtures and installations as originally built, so your HO-6 mainly covers upgrades and betterments beyond that. Check the declaration or ask the HOA which type applies, since it changes how much dwelling coverage your unit needs.
A unit insured for too little under a bare walls declaration leaves the owner paying out of pocket to replace drywall, cabinets, and flooring after a fire or burst pipe, since the master policy stops at the studs. Comparing HO-6 quotes now means checking that dwelling coverage actually matches what the declaration leaves on your side of the wall, not what last year's policy happened to carry.
What happens when water comes from the unit next door
Water damage is the most common way a condo owner ends up dealing with two policies at once. If a pipe bursts in the unit above and soaks the ceiling and flooring below, the question of who pays starts with whose plumbing failed and where the damage landed. The upstairs owner's HO-6 liability coverage may apply if negligence caused it, say a known leak that went unreported. In practice, each owner's own HO-6 often pays for the damage to their own unit first, under the coverage for walls, flooring, and personal property. Any dispute over fault usually gets worked out separately between insurers or owners.
Loss assessment coverage on an HO-6 matters as much as the dwelling limit. Damage can hit shared areas like a hallway, roof, or the building's main plumbing stack, and the master policy's deductible or limit doesn't always cover the full repair. When that happens, the HOA can issue a special assessment that bills every unit owner a share of the cost. Loss assessment coverage reimburses the owner for that bill, up to the policy's limit. It's typically a modest add-on, but after a major structural loss the assessment can run into thousands of dollars per unit, so it's worth checking what limit the policy actually carries rather than assuming it's enough.
Townhome insurance works differently depending on what the townhome owner actually owns. Some townhome communities are structured like condos, with an HOA master policy covering the exterior walls and roof and the owner holding an HO-6 for the interior. Others are set up so each townhome owner owns the entire structure, including the roof and exterior walls, down to the ground it sits on. In that case, the right policy is a standard HO-3 homeowners policy, not an HO-6, because there's no master policy covering the shell of the building. The HOA documents, or a quick call to the association, will say which situation applies.
The deciding document is the HOA's declaration and bylaws, not assumptions carried over from a previous home. A unit owner moving from a single-family house to a condo, or buying a townhome for the first time, should read that document before choosing coverage. It sets the boundary the policy has to fill in.
How much HO-6 coverage does a unit actually need
There's no flat number that works across condos, because the declaration sets a different starting point in every building. A unit in a bare walls building needs enough dwelling coverage to rebuild drywall, flooring, cabinets, countertops, and built-in fixtures from scratch, which can run tens of thousands of dollars depending on finishes. A unit in an all-in building needs less dwelling coverage, since the master policy already handles those items as originally installed, but still needs enough to cover upgrades the owner added, like refinished floors or a renovated kitchen.
A practical way to size the number is to add up what it would cost to replace everything inside the unit that the master policy doesn't reach. That includes the interior surfaces specific to the declaration type, plus any improvements made since the unit was built. Contractors and public adjusters use the term betterments and improvements for exactly this category, and some HO-6 policies sell it as a separate coverage line rather than folding it into the dwelling limit. Reading the declarations page for that line item, and comparing it against what was actually spent on renovations, catches the gap before a claim does.
Personal property coverage is a separate number from dwelling coverage and gets undersized just as often. It needs to reflect the furniture, electronics, and belongings actually in the unit, not a default the insurer picked. Liability coverage matters too, particularly in a condo, since a fire or water leak that starts in one unit and spreads to others can draw a liability claim from a neighbor whose unit was never insured the same way.
None of these numbers come from guessing. The declaration says what the master policy covers, a contractor or the HOA's own records can price out what a full interior rebuild costs, and receipts or a room-by-room inventory price out personal property. A new condo owner who carries over a coverage number from a past rental policy or a different unit's policy is usually carrying over the wrong number, since no two buildings split ownership exactly the same way.

Pull the HOA declaration and find the line that says bare walls or all-in. That single phrase decides how much dwelling coverage your unit needs and whether your loss assessment limit is enough.
