Is Your Property Storm-Ready? Tree Liability in Ireland
Storm Éowyn hit Ireland in January 2025 with winds exceeding 180 km/h in parts of the west. Trees came down on cars, buildings, roads, and power lines across Clare, Galway, Limerick, and beyond. Some of those trees were on private commercial property. Some of those owners had no idea they were liable.
Is your property storm-ready? In this guide, you’ll learn exactly what your legal obligations are as a business owner or commercial property manager when it comes to trees, what happens when something goes wrong, and what steps you can take right now to protect yourself.
Is Your Property Storm-Ready? Understanding Tree Liabi
lity in Ireland
Tree liability in Ireland is not a straightforward area of law, but the core principle is clear. If a tree on your property falls and causes damage or injury, and you knew or should have known the tree was a risk, you can be held liable.
The key phrase there is “knew or should have known.” You don’t have to have been warned specifically about a tree to be held responsible. A court can find that a reasonable property owner would have identified the risk through proper inspection. Ignorance is not a defence.
This matters most for business owners, commercial landlords, and anyone managing a property with significant tree coverage. A hotel in Clare with mature trees along its driveway, a retail park in Limerick with oaks along its perimeter, a business park in Galway with trees near the car park. All of these carry exposure.
What Irish Law Says About Tree Liability
There is no single piece of Irish legislation that covers tree liability specifically. It falls under general occupier’s liability law, primarily the Occupiers’ Liability Act 1995.
Under this Act, you owe a duty of care to visitors on your property. That duty extends to keeping the property reasonably safe, which includes managing trees that pose a foreseeable risk. If a visitor is injured by a falling branch or tree that you should have identified as dangerous, you are exposed to a civil claim.
The standard applied by Irish courts is that of a “reasonable person” in your position. A business owner with a large commercial property is expected to take reasonable steps to assess and manage tree risk. That typically means periodic professional inspection, documentation, and action on identified hazards.
When Is a Business Owner Liable for Tree Damage? 
Liability usually hinges on one of three situations.
The first is where you had prior notice of a problem. A tree surgeon, a council inspector, or an employee told you a tree was dangerous and you did nothing. That’s the clearest route to liability.
The second is where a professional inspection would have identified the risk. Even without a specific warning, if a qualified arborist would have spotted the hazard during a standard survey, a court may find you should have commissioned that survey.
The third is where the tree was obviously in poor condition. A tree that was visibly dead, heavily leaning, or decayed at the base presents an obvious risk. Property owners are expected to notice these things.
Storm Damage: What Happens After a Tree Falls?
If a tree on your property falls during a storm and damages a neighbouring property or vehicle, the storm itself does not automatically absolve you of responsibility. This surprises a lot of business owners.
Irish courts have found that where a property owner was aware of a tree’s poor condition, they remain liable for storm damage even when the weather was severe. The storm is considered a foreseeable event, not an unforeseeable act of nature that removes liability.
The situation is different if you had no notice of a defect and a structurally sound tree came down in an exceptionally severe storm. In that scenario, you have a much stronger defence. But you need evidence to support it, including inspection records.
The Role of Tree Surveys in Protecting Your Business 
A professional tree survey is your single most important protection against liability. It documents the condition of every tree on your property, identifies any that are hazardous, and recommends action.
If you commission a survey, act on the recommendations, and keep records, you demonstrate that you took reasonable steps. If a tree then fails in a storm, you have evidence that you met your duty of care. Without a survey, you have nothing.
Elm Landscaping and Tree Surgery carry out professional tree surveys and risk assessments for commercial clients across Clare, Limerick, Galway, and Tipperary. Their arborists hold RQF Level 5 qualifications or higher, which is the professional standard recognised by the arboriculture industry in Ireland.
How Often Should Commercial Properties Survey Their Trees?
There is no fixed legal requirement specifying a survey interval. Industry guidance from arborist bodies typically recommends the following.
| Property Type | Recommended Survey Frequency |
|---|---|
| Low-risk sites with young trees | Every 5 years |
| Standard commercial premises | Every 3 years |
| High-footfall sites (retail, hotels) | Every 2 years |
| Sites with mature or veteran trees | Annually |
| Post-storm inspection | After every significant storm event |
High-footfall sites like retail parks, hotels, and business campuses carry higher liability exposure simply because more people are on the property. A Dunnes Stores car park in Ennis or a hotel driveway in Kilaloe needs more regular attention than a low-footfall industrial unit.
Post-storm inspections are just as important as routine surveys. A storm can damage a tree structurally without knocking it down. A tree that looks fine after a storm may have root damage, basal cracking, or crown failure developing that makes it a serious hazard in the following months.
What to Do Before the Next Storm Season 
Storm season in Ireland runs broadly from October through March. That gives you a window now to get on top of any tree issues before the next serious weather event arrives.
Here’s a practical checklist for commercial property owners.
Walk your site and make notes on any trees that are visibly dead, leaning abnormally, have major dead branches, show signs of fungal growth at the base, or are in close proximity to buildings, car parks, or walkways. These are your priority risk areas.
Commission a professional tree survey if you haven’t had one in the last two to three years. Make sure you get a written report with recommendations, not just a verbal walkthrough.
Act on the recommendations. If a tree surgeon recommends crown reduction, removal, or cabling, arrange that work before storm season. Documented action is your defence.
Review your insurance policy. Check whether your public liability cover includes tree-related incidents and what documentation your insurer requires in the event of a claim.
Keep all records. Survey reports, correspondence with tree surgeons, invoices for completed work, and site inspection notes should all be stored and accessible.
What Does Tree Surgery Work Cost for Commercial Properties?
Getting the work done is the part that most business owners put off. Here’s a realistic picture of 2026 costs in the Munster and Connacht market.
| Service | Typical Cost Range |
|---|---|
| Professional tree survey (full site) | €300 to €1,000+ depending on site size |
| Crown reduction (per tree) | €250 to €600 |
| Tree removal (small to medium) | €300 to €800 |
| Tree removal (large or dangerous) | €800 to €3,000+ |
| Stump grinding (per stump) | €100 to €300 |
| Emergency storm callout | €500 to €2,000+ |
| Ongoing maintenance contract | €1,500 to €5,000 per year |
Emergency callout after storm damage is consistently the most expensive way to manage trees. A planned removal carried out before a storm costs a fraction of an emergency response, and it eliminates the liability exposure entirely.
Elm Landscaping work with major commercial clients including IDA Ireland, Regeneron, Aramark, and NUI Galway. They offer commercial maintenance contracts that cover regular inspection, reactive work, and documentation. For a business owner managing a large site, a contract arrangement is usually more cost-effective than ad hoc callouts.
Trees on Boundary Lines: A Common Source of Disputes
Boundary trees cause a specific set of problems for commercial property owners. If a tree sits on or near a boundary between your property and a neighbouring one, ownership and responsibility can be contested.
In Irish law, a tree belongs to whoever owns the land on which the trunk stands. If the trunk straddles the boundary, ownership is shared. That means liability is also potentially shared, and disputes between neighbours or adjacent commercial landowners over tree responsibility are not uncommon.
If you have boundary trees and you’re unsure of the ownership position, get it clarified before there’s a problem. A tree survey from a qualified arborist that documents the exact position of the trunk, the spread of the canopy, and any identified hazards creates a clear record that protects you in a dispute.
