My upstairs neighbor's leak damaged my condo ceiling. Who pays?

Unless the neighbor was negligent, they knew about the leak and ignored it, they're generally not automatically liable for a sudden failure. Each policy typically covers its own layer: the HOA master policy for what the declarations assign to it, your HO-6 for your interior and belongings. File with your own carrier promptly; it can pursue the neighbor's insurer if negligence is in play.

The HOA says the damage inside my unit isn't their problem. Are they right?

Maybe, it depends entirely on the declarations and the master policy type. Under a bare-walls structure, interior drywall, flooring, and cabinets genuinely are the owner's responsibility. Ask for the master policy declarations and the CC&R sections on insurance and maintenance rather than accepting a phone answer; if the documents are ambiguous, that's a question for your insurer or an attorney.

What is loss assessment coverage and do I need it?

It's an HO-6 endorsement that pays your share when the association assesses owners for a covered loss, most often the master policy's deductible, which commonly runs into five figures in Arizona communities. If your CC&Rs allow assessing the deductible to owners (or to the originating unit), it's one of the cheapest meaningful protections a condo owner can carry.

Does any of this change if I rent out my condo?

The framework is the same, but your policy type changes, landlords typically carry a condo unit-owner policy adapted for rental (and lose coverage for a tenant's belongings, which is what the tenant's renters policy is for). Water damage responsibility between you, the tenant, the HOA, and other owners still runs through the same documents: CC&Rs, master policy, and your unit policy.

Water damage in an Arizona condo: who pays, you or the HOA?

In Arizona, who pays for condo water damage depends on three documents, not on whose unit the water came from: the association's CC&Rs, the HOA's master insurance policy, and your own HO-6 policy. Arizona law (A.R.S. § 33-1253) requires the association to insure the common elements, and often the units themselves, but whether the master policy stops at the bare walls or covers original interior finishes is set by your community's declarations, and that line determines which policy pays for your drywall, flooring, and cabinets.

Condo water losses are messier than single-family ones because water ignores property lines: a washing-machine hose fails upstairs and three units plus a common hallway get wet. Owners assume the person whose unit the water came from pays, or that "the HOA handles the building." Neither is reliably true. This guide walks through how responsibility actually gets sorted in Arizona, the statute, the documents, and the practical steps that protect you while it's sorted out. It's general information, not legal advice; your CC&Rs and policies control.

The Arizona baseline: A.R.S. § 33-1253

Arizona's Condominium Act requires condo associations to maintain property insurance on the common elements, and, to the extent reasonably available, on the units, for at least 80% of actual cash value, plus liability coverage. What the statute deliberately doesn't do is fix where the association's responsibility ends inside your unit. That boundary is set by your community's declarations (CC&Rs), which is why two Arizona condos across the street from each other can split the same loss completely differently.

In practice, master policies fall on a spectrum. "Bare walls" coverage stops at the structural shell, everything inside your unit, including drywall surfaces, flooring, cabinets, and fixtures, is on you. "All-in" (or "walls-in") coverage extends to original interior finishes and built-ins, leaving you responsible mainly for upgrades and personal property. Most communities sit somewhere between, and the only way to know is to read the declarations and the master policy's coverage type.

When the water comes from another unit

The most common condo scenario, an upstairs supply line or water heater fails and your ceiling comes down, is also the most misunderstood. The upstairs owner is not automatically liable for your damage just because the water originated there; in general, liability attaches when they were negligent (they knew about the leak and ignored it, for example), not when a part simply failed without warning. Absent negligence, each layer of the loss typically falls to whichever policy covers that layer: the master policy for what it covers, your HO-6 for your interior and belongings, theirs for theirs.

This surprises people, but it's why your own HO-6 matters so much: for a no-fault failure upstairs, your own policy is often what actually pays for your unit's interior, and your carrier may then pursue the other parties if there's a negligence case to make.

Your HO-6 layer, and the two coverages that matter most

An HO-6 condo policy covers what the master policy doesn't: the interior of your unit (its Coverage A / dwelling limit), your personal property, and liability. For water losses specifically, two features deserve attention. First, the Coverage A limit needs to reflect what you'd actually pay to rebuild your interior if the master policy is bare-walls, flooring, cabinets, and countertops add up fast. Second, loss assessment coverage: master policy deductibles in Arizona communities commonly run into five figures, and associations can, depending on the governing documents, assess that deductible to owners, sometimes specifically to the owner whose unit the loss originated in. Loss assessment coverage is the endorsement that responds when that happens.

Ask your HOA for the master policy type (bare-walls vs. all-in) and its deductible. If the deductible is five figures and your CC&Rs allow assessing it to the originating unit, a $40 supply line failing in your laundry closet could make you personally responsible for the full master deductible. Loss assessment coverage on your HO-6 exists for exactly this.

What to do when it actually happens

The insurance sorting takes weeks; the water damage compounds in days. Handle the loss first and the responsibility question second.

1
Stop the water
Shut the supply at the fixture or the unit's shutoff. If the source is another unit or a common line, notify the neighbor and the HOA's emergency contact immediately, associations can access common-element plumbing you can't.
2
Document before anything is moved or dried
Photograph and video every affected surface in your unit, including the apparent source and path of the water. In multi-unit losses, your documentation is your evidence when three insurers later negotiate who owed what.
3
Notify the HOA and your HO-6 carrier, both, in writing
Don't wait for the association to decide whose problem it is before telling your own insurer. Prompt notice is a policy condition, and your carrier can start on your interior while the master-policy question gets sorted.
4
Get the wet materials dried now
Mold starts within 24–48 hours and doesn't wait for coverage decisions. Mitigation is separately valuable regardless of who ultimately pays, and policies require you to prevent further damage. Keep every invoice.
5
Pull the documents
Request the CC&Rs, the master policy declarations page, and the certificate of insurance from the HOA. The answers to "who pays" are in those documents, not in what anyone at the association says on the phone.
