Can You Sue Your Neighbour Over a Smell? Sometimes, and the Test Is Reasonableness
By the BrainSnail editorial team. How these articles are written and checked, and how to tell us when one is wrong.
The law protects the use and enjoyment of land against substantial unreasonable interference, which covers noise, smell, smoke and vibration but not the loss of a nice view.
What the claim protects
The wrong consists of an unreasonable interference with somebody's use or enjoyment of their land. It is a claim about land rather than about people, so the claimant must have an interest in the affected property, and the complaint is about the effect on that property rather than about personal annoyance. The interference need not involve entering the land, which distinguishes it from trespass. Physical damage to the property counts, and so does interference with comfort, which is where most of the difficulty lies since comfort is a matter of degree.
What courts weigh
Reasonableness is assessed against several factors together:
- •How severe the interference is, and how long it lasts
- •The character of the neighbourhood, which sets expectations
- •Whether the activity has any social utility
- •Whether the defendant acted out of malice
- •Whether the claimant is unusually sensitive
- •Whether the interference is continuous or occasional
The famous limits
Several settled principles define the edges and each rests on a memorable case. Coming to the problem is no defence, so a person who buys a house next to an existing factory may still complain, which was established in a nineteenth century case about a doctor building a consulting room beside a confectioner's machinery. Malice matters, since deliberately making noise to annoy a neighbour was held unreasonable where the same noise made innocently would not have been. Unusual sensitivity fails, so a claimant whose particular trade is disrupted by something harmless to ordinary use generally cannot recover. And there is no right to a view.
How it relates to planning rules
Public regulation and private claims cover much of the same ground and their relationship confuses people regularly. Obtaining planning permission for an activity does not license a private wrong, so a lawfully built development can still be the subject of a claim, though permission may change the character of the neighbourhood in a way that affects what counts as reasonable. Statutory regimes governing noise, smoke and waste operate alongside the private claim rather than replacing it, and a local authority can act where no individual will. Some statutes expressly authorise an activity and provide a defence, which is why major infrastructure is usually built under specific legislation.
What a successful claim achieves
The remedies available shape what the claim is actually used for. A court may award damages for the harm suffered, and more importantly may grant an injunction ordering the activity to stop or to be limited, which is what most claimants want. Courts have discretion to award damages instead of an injunction where the harm is small and an injunction would be oppressive, and how freely that discretion should be used is a live argument, since awarding damages effectively lets a defendant buy the right to continue. A separate public version of the wrong exists where a whole community is affected, and is usually pursued by authorities.
The takeaway
The claim protects use and enjoyment of land against substantial unreasonable interference, judged against severity, duration, neighbourhood character, utility, malice and the claimant's own sensitivity. Moving in next to an existing problem is no defence, malice counts against a defendant, and there is no right to a view. An injunction rather than damages is what most claimants are after.
