A tree that falls on a car, a roof, or a person turns a landscaping question into a legal one very quickly. Boards often assume that if a tree fell in a storm, it was an "act of God" and nobody is on the hook. Sometimes that is true. Often it is not. The difference usually comes down to one thing: what the association knew, or should have known, about that tree before it came down.
This is a general overview, not legal advice — tree law varies by state and your association's attorney is the right person for a specific situation. But every board should understand the basic framework.
The legal standard usually turns on "notice"
In most states, liability for a fallen tree hinges on whether the owner had notice that the tree was hazardous. A perfectly healthy tree that comes down in an extreme storm is generally treated as an act of nature, and the association is unlikely to be liable. A visibly dead, diseased, or leaning tree that the association ignored for two years is a different story — that starts to look like negligence.
The practical question a court or insurer asks is: Was there a reasonable warning sign, and did the association act on it? Notice can be:
- Actual notice — someone reported the dead tree, or the board saw it and did nothing.
- Constructive notice — the hazard was obvious enough that a reasonable inspection would have caught it, whether or not anyone actually did.
This is why "we didn't know" is a weak defense when the tree had been dead and bark-bare for a year in plain view.
Who owns the tree matters
Responsibility starts with who owns the ground the trunk stands on.
- Trees on common area are the association's responsibility. This is the bulk of the board's exposure.
- Trees on a homeowner's lot are generally the homeowner's responsibility, though the governing documents can shift maintenance duties either way — read them.
- Boundary and encroaching trees — where a tree straddles a property line or its limbs cross onto a neighbor's lot — are a common source of disputes and depend heavily on state law.
When a homeowner's tree threatens common area, or a common-area tree threatens a home, the board should document the hazard in writing and communicate about it rather than letting it sit.
The board's real job: a defensible inspection routine
You cannot control the weather. You can control whether your association looks like it managed its trees responsibly. The single most protective thing a board can do is maintain a routine, documented tree inspection.
- Inventory the common-area trees. You cannot monitor what you have not counted.
- Schedule regular visual assessments, at least annually and after major storms.
- Bring in a certified arborist for anything questionable. An ISA Certified Arborist can perform a formal tree risk assessment and give you a written record that carries real weight.
- Document everything — what was inspected, what was found, and what was done about it. This record is your best defense.
The goal is to be able to show that the association had a reasonable system for catching hazards, and acted when it found one.
Warning signs worth acting on
Between formal inspections, these are the signs that a tree needs professional attention:
- Large dead branches or a dead top ("stag-heading")
- A sudden lean, or soil heaving and cracking at the base
- Deep cracks in the trunk or major limbs
- Mushrooms or conks growing at the base, which can signal root or trunk decay
- Cavities, hollows, or extensive bark loss
- Branches overhanging roofs, walkways, playgrounds, or parking
A hazard over a playground or a parking area deserves faster action than one over an empty lawn. Prioritize by what is underneath.
A canopy this size is read at both ends — dead branches and a dead top overhead, cracks, conks and heaved soil down at the base.
Act on hazards before they become claims
Reactive tree work — removing a limb after it has already fallen — is legally the worst position to be in, because by then the notice question answers itself. Once you have notice of a hazard, delay is the thing that creates liability. Get a professional assessment, and if removal or pruning is recommended, budget for it and do it. A hazardous-tree removal is the kind of line that arrives all at once and does not fit neatly into a monthly grounds budget, which is exactly why boards defer it and exactly why deferring it after notice is the mistake.
Where HOAcrew fits
Know your trees, act on what you find, and keep the proof. The inspection routine and the written record are the substance here, and a certified arborist and your association's attorney are the two people who make them stand up. What tree liability comes down to on the day it is tested is whether the association can produce a dated record of the hazard being found and the hazard being dealt with.
HOAcrew is where a board holds that record. Vetted independent local landscaping and tree-care companies submit proposals against the scope you publish — the annual visual assessment, the post-storm walk, the removals the arborist called for. Your board compares them side by side, selects one, and the contract is between your community and the company it chose. HOAcrew verifies the three documents that decide a bid — general liability, workers' compensation and the credential that company's trade requires, and an admin reads each certificate of insurance and files what the document says, with every expiry date held against the limits your community sets — worth reading closely in tree work, where the thing that can go wrong is large and falling. The arborist assesses and the crew climbs; the report, the photos, the date the limb came down and the company's own invoice arrive in one view, which is exactly what you want to hand your attorney rather than a search of somebody's old email.
