19. Private Nuisance
An owner or occupier of land has a duty to avoid substantial and unreasonable interference with the use and enjoyment of the land of others. Breach of this duty constitutes a private nuisance.
- Private nuisance is a tort (now usually embodied in a statutory right of action) brought by one landowner/occupier against another.
- A nuisance does not require trespass upon the land; it need only interfere with the plaintiff ’s use and enjoyment of their land.
- Typical nuisances include obnoxious smells, noise, or sights.
- Only a substantial and unreasonable interference will constitute a nuisance. When determining whether an interference is substantial and unreasonable, a court will balance the equities, including the nature of the plaintiff ’s harm, the interests of the defendant, and the nature of the surrounding area.
- The plaintiff ’s harm is judged by harm to the ordinary person, not by any special sensitivities of the plaintiff .
- One factor courts consider in striking this balance is whether the defendant’s activity predated the plaintiff ’s ownership or occupation of the land. “Coming to the nuisance,” however, is just one factor that courts consider as part of the unreasonableness determination.
- Most nuisances result from intentional acts, meaning that the defendant is aware of the interference and allows it to continue.
- Remedies for nuisance include damages and the possibility of an injunction.
- The Nevada FLE does not test claims for nuisance based on negligence, recklessness, or strict liability.
Private nuisance is a substantial and unreasonable interference with another's use and enjoyment of land. It needs no trespass, the harm is judged by the ordinary person, and an injunction is only a possibility, not a guarantee.
Private nuisance is a property concept, not a general personal-injury tort, and the whole claim turns on one phrase you have to keep intact: substantial and unreasonable interference with the use and enjoyment of another's land. Both words carry weight. An interference that is merely annoying but minor is not substantial; an interference that is substantial but justified, given everything around it, is not unreasonable. The plaintiff needs both, and an answer choice that asks for only one of them is wrong.
The first thing students misremember is that nuisance is about interference, not invasion. A nuisance does not require any trespass onto the plaintiff's land; nothing has to physically cross the boundary. Smells drifting over, noise carrying across, an unsightly junk pile in view next door, all of these interfere with use and enjoyment without anyone or anything entering the plaintiff's parcel. Trespass and nuisance are separate ideas: trespass protects possession against entry, nuisance protects use and enjoyment against interference.
The second thing to hold onto is how the court measures substantial-and-unreasonable: it balances the equities, weighing three factors.
- 1The nature of the plaintiff's harm, judged by harm to the ordinary person in the plaintiff's position, never by the plaintiff's own special sensitivities.
- 2The interests of the defendant.
- 3The nature of the surrounding area.
Most nuisances are intentional, which here has a specific meaning: the defendant is aware of the interference and allows it to continue. It does not require malice or a desire to harm, just awareness plus continuation. As for remedies, the plaintiff can recover damages, and an injunction is a possibility, not a guarantee; because the court balances the equities, it may award damages but decline to shut the activity down.
Several facts look decisive but are not. That the defendant never physically intruded on or entered the land is testing the trespass element by mistake; nuisance needs no trespass. That this plaintiff is unusually delicate or runs a hypersensitive business does not make an ordinary activity a nuisance, because harm is judged by the ordinary person. And 'coming to the nuisance,' the fact that the defendant's activity was already there when the plaintiff arrived, is just one factor in the balance, not a complete defense or automatic bar. Finally, an answer that treats an injunction as automatic once a nuisance is shown overstates the remedy.
The Nevada FLE does not test nuisance built on negligence, recklessness, or strict liability. Any option that grounds the claim in the defendant's failure to use reasonable care, in reckless conduct, or in an abnormally dangerous strict-liability theory is importing law that is out of scope.
"substantial and unreasonable, use and enjoyment, no trespass needed."
That single line is the whole claim: a substantial and unreasonable interference with use and enjoyment, with nothing required to physically cross the line.
"the defendant never entered or invaded the land", irrelevant, nuisance needs no trespass
"this particular plaintiff is unusually sensitive", irrelevant, harm is judged by the ordinary person
"the defendant was there first", just one factor, not a complete defense
"the defendant wasn't careful / was reckless / ran a dangerous operation", out of scope, nuisance here is not a negligence/recklessness/strict-liability claim
And two more: it must be both substantial and unreasonable, not one or the other; and an injunction is only a possibility, never automatic.
A homeowner buys a house in a mixed residential-and-light-industrial area. A small metal-finishing shop has operated two lots away for years, and after the homeowner moves in the shop continues running, emitting a faint chemical odor on most afternoons and a low mechanical hum during business hours. The shop's operator knows the odor and noise reach the neighborhood and keeps the shop running anyway. The homeowner, who has an unusually acute sense of smell, finds the odor far more distressing than her neighbors do, and sues the shop operator for private nuisance, seeking damages and an order shutting the shop down.
Judged by the ordinary person and the surrounding area, her odor-and-noise claim is weak, and her heightened sensitivity cannot rescue it. The strongest defense points are the ordinary-person standard and the area's character, not the bare fact that the shop arrived first and not any absence of a physical trespass.
A “No” answer that denies a nuisance because the defendant never physically entered, invaded, or intruded onto the plaintiff's land, treating nuisance as if it required a trespass.
A nuisance requires no trespass; it need only interfere with the plaintiff's use and enjoyment, so drifting smells, noise, or sights suffice without any physical entry.An answer that turns on the plaintiff's unusual sensitivity, letting a hypersensitive plaintiff win on harm that an ordinary occupant would shrug off.
The plaintiff's harm is judged by harm to the ordinary person, not by any special sensitivities of the plaintiff.An absolute answer treating “coming to the nuisance” (the defendant got there first) as a complete defense or automatic bar, or an answer that makes any audible/visible activity automatically a nuisance.
Coming to the nuisance is just one factor in the unreasonableness balance, not a complete defense; and whether something is a nuisance always runs through the substantial-and-unreasonable balance, never an absolute rule.An answer that frames the claim in negligence (failure to use reasonable care), recklessness, or strict liability / abnormally dangerous activity.
The Nevada FLE does not test nuisance based on negligence, recklessness, or strict liability; the claim rests on a substantial-and-unreasonable interference the defendant is aware of and allows to continue.An answer that says an injunction issues automatically or is guaranteed once a nuisance is shown, or that requires only one of substantial/unreasonable.
An injunction is only a possibility, decided by balancing the equities (damages may issue instead); and the interference must be BOTH substantial AND unreasonable.the stem hands you two neighboring landowners or occupiers and a drifting, carrying, or visible annoyance, odor, noise, light, smoke, an unsightly pile, that bothers one of them without anything physically crossing the boundary, then loads in a tempting off-ramp: "nothing ever entered the plaintiff's land," "this plaintiff is unusually sensitive," "the defendant was operating there first," "the defendant wasn't negligent," or "so the court must enjoin it."
The instant you see an interference with use and enjoyment dressed up with one of those, run the check: is the interference both substantial (to an ordinary person) and unreasonable (on a balance of the nature of the harm, the defendant's interests, and the surrounding area), and is the defendant aware of it and allowing it to continue?
If yes, it is a private nuisance, no trespass required, and every answer resting on no-physical-entry, special sensitivity, coming-to-the-nuisance-as-a-bar, a negligence/recklessness/strict-liability theory, or an automatic injunction is a distractor.
A homeowner lives next to a property where a neighbor operates a backyard smokehouse. For several hours most days, thick, greasy smoke and a strong smell drift across the property line and settle over the homeowner's yard and into the house, making it unpleasant to sit outside or keep the windows open. None of the smoke residue ever physically settles on or damages the homeowner's land, and the neighbor has never set foot on the homeowner's property. An ordinary person in the homeowner's position would find the daily smoke and odor a serious interference with using and enjoying the yard. The homeowner sues the neighbor for private nuisance.
Is the homeowner likely to establish a private nuisance?
A resident operates a recording studio in a quiet residential neighborhood and is extremely sensitive to low-frequency sound. A neighbor runs a small home workshop with a quiet ventilation fan that produces a faint hum during the day. An ordinary person living next door would not be bothered by the hum and would barely notice it, but because of the resident's unusual sensitivity the faint hum ruins his ability to make recordings. The resident sues the neighbor for private nuisance, pointing only to how severely the hum affects his particular work.
Is the resident likely to establish a private nuisance?
A farmer has operated a hog-raising operation at the edge of an agricultural district for many years, and it has always produced strong, persistent odors. A homeowner later buys a newly built house just inside the district, near the farm, and finds the odors a serious and constant interference with using and enjoying the property; an ordinary person in that location would be substantially bothered as well. The homeowner sues the farmer for private nuisance. The farmer's only response is that the operation was there long before the homeowner arrived.
How should the court treat the fact that the farm predated the homeowner's purchase?
A factory operator runs a plant in a residential area that emits a loud, grinding noise around the clock. The noise is plainly a substantial interference, and an ordinary person living nearby would be seriously disturbed by it. A resident next door sues for private nuisance. At trial, after the court balances the nature of the resident's harm, the operator's interests, and the character of the surrounding residential area, it concludes that the around-the-clock noise in this residential setting is also unreasonable. A second resident, two streets away, hears only a faint, occasional sound that an ordinary person would find trivial, and the court finds that interference neither substantial nor unreasonable.
Which resident has established a private nuisance?
A neighbor installs bright floodlights that shine directly into the adjacent homeowner's bedroom windows every night, substantially and unreasonably interfering with the homeowner's use and enjoyment of the home, as an ordinary person would agree. The homeowner tells the neighbor about the problem, but the neighbor, fully aware of how the lights affect the home, leaves them on as they are. The neighbor bears the homeowner no ill will and simply prefers the lights. The homeowner sues for private nuisance and asks the court both for damages and to order the lights turned off.
