The trickiest liability questions I deal with as a property manager are almost never inside a unit. They are in the in-between places: the shared stairwell, the parking lot, the walkway between buildings, the retaining wall at the edge of the common grounds. When someone is hurt in one of those spaces, the first question is who was responsible for maintaining it, and in a building with a landlord, or a community with an HOA, the answer is rarely as obvious as people assume.
The general principle
Responsibility for a hazard tends to follow control. Whoever controls and is obligated to maintain a given area generally carries the duty to keep it reasonably safe, and the liability if they knew or should have known about a hazard and failed to address it. In a rental, common areas, halls, stairs, shared walkways, exterior grounds, are typically the landlord’s responsibility, while the interior of a leased unit is more shared and depends on the lease. In a condo or HOA community, the governing documents draw the line between what the association maintains, usually the common elements, and what each owner maintains.
This is general information, not legal advice, and the specifics turn on your lease, your CC&Rs, and your state’s law. But the framework, control plus knowledge, is remarkably consistent, and a licensed professional in your state can apply it to a specific situation.
Knowledge is what turns a hazard into liability
The recurring theme across every common-area case is knowledge. An owner or association that had actual notice of a hazard, a reported broken step, a documented leaning retaining wall, a work order about a loose handrail, and did not fix it within a reasonable time is in a far worse position than one facing a genuinely sudden, unforeseeable failure. “Should have known” matters too: a hazard that a reasonable inspection would have caught can count as constructive knowledge even without a report. That is why documented inspections and prompt repairs are not just good practice, they are the core of the defense.
The flip side is the trap: a hazard you were told about, logged, and then let sit is close to the worst possible fact pattern, because your own records prove you knew.
Where the HOA line gets blurry
HOA cases get complicated because the boundary between common element and owner responsibility is not always where people think. A balcony might be a limited common element the owner maintains but the association is responsible for structurally; a retaining wall might sit on common ground but protect specific lots. When a hazard falls on a contested boundary, both the association and an owner can end up with a share of responsibility, and the governing documents are the first place anyone looks to sort it out. Structural common elements, a failing retaining wall on association land, a deck or balcony, deserve particular attention, because their failures are both expensive and dangerous, and knowing when one needs an engineer and a permit is part of managing that risk responsibly.
Managing the risk in practice
The practical playbook is the same whether you are a landlord or an HOA board: inspect common areas on a schedule, document what you find with dates and photos, act on hazards promptly, and keep the records. Holding common areas to the maintenance and safety standards in the model codes published by the International Code Council is a defensible baseline for what “reasonably safe” looks like. A routine, followed and documented, does two things at once, it actually keeps people safer, and it gives you the evidence that you met your duty if something happens anyway. Deferring a known common-area repair to save money is the decision that comes back most expensively, because it converts a maintenance cost into a liability exposure.
Frequently asked questions
Is the landlord always responsible for common-area injuries? Usually the landlord is responsible for maintaining common areas like halls, stairs, and shared walkways, and can be liable if a known hazard was not addressed. But it depends on the lease, the circumstances, and whether the hazard was known or reasonably discoverable.
Who is responsible in an HOA, the association or the owner? It depends on whether the hazard is in a common element (usually the association) or an owner-maintained area, as defined by the governing documents. Contested boundaries, like balconies or walls serving specific lots, can involve both. The CC&Rs are where it starts.
What is the best protection against these claims? Scheduled inspections, dated documentation, and prompt repair of known hazards. A followed, documented routine both prevents injuries and demonstrates you met your duty, which is the opposite of the worst case: knowing about a hazard and leaving it unfixed.
