Apartment & Condo Burst Pipe Guide — Who Pays for What
Multi-unit water losses involve multiple policies, multiple parties, and often unclear responsibility. Here's how it usually breaks down in Minnesota.

Not legal advice. This is a general framework; your HOA documents and specific policies govern.
The parties in a multi-unit water loss
- HOA or condo association (and its master insurance policy)
- Unit owner where the leak originated
- Unit owner(s) affected by water migration from the source unit
- Tenants (if the units are rented)
- Property management company (if the HOA uses one)
- Commercial tenants in mixed-use buildings
The policies in play
- HOA master policy covers structural components (the building itself), common areas, and typically either "bare walls" or "all-in" unit interiors per the association documents.
- HO-6 unit owner policy covers interior improvements, personal property, loss assessments levied by the HOA, and personal liability.
- HO-4 renter policy covers tenant personal property and liability.
- Commercial tenant policy covers commercial tenant improvements and business property.
Who pays — common patterns
Supply-line failure inside a wall between units: Often the HOA's responsibility because the pipe is a common element. Damage to unit interiors beyond the standard finish is typically the unit owners' HO-6s.
Fixture failure within a specific unit (toilet supply, sink angle stop, washer hose): Usually the unit owner's HO-6, with the HO-6 covering liability to downstream units.
Common-element failure in shared mechanical space: HOA master policy.
Fire sprinkler event: Usually HOA master policy for the system; unit damage per the breakdown above.
The loss assessment
If the HOA's deductible is higher than individual claim amounts, or if the HOA is underinsured, it may issue a loss assessment to each unit owner to cover its share of the loss. HO-6 policies include limited loss-assessment coverage (often $1,000–$2,000 default, with higher endorsement options).
Practical steps if you're affected
- Notify your property manager/HOA immediately.
- File a claim under your HO-6 for your unit's damage.
- Document everything — photos, affected items, timeline.
- Don't let the HOA tell you to use only their contractor — in Minnesota you can choose your own restoration contractor for your unit.
- Keep receipts for anything you spend.
