What Is the Difference Between Public and Private Nuisance?
This post is part of the Brieflex Torts Deep Dive series — where we break down the torts most tested in law school and on the bar. After exploring Conversion and Trespass to Chattels — dominion vs. interference and Battery and Assault — contact vs. apprehension, we turn to Nuisance — the tort that protects the use and enjoyment of land. The key distinction? Private nuisance affects individuals; public nuisance affects the community.
The Core Difference: Who’s Harmed
Both public and private nuisance involve unreasonable interference with someone’s right to use and enjoy property — but they differ in scope and standing.
- Private Nuisance protects an individual landowner’s interest in using or enjoying their land.
- Public Nuisance protects the public’s collective interest in health, safety, or comfort.
The harm defines the claim: if it affects a person, it’s private; if it affects a community, it’s public.
Private Nuisance
Rule:
Private nuisance is a substantial and unreasonable interference with the use and enjoyment of land by another.
Elements:
- Interference – Conduct by D that affects P’s use or enjoyment of land.
- Substantial Harm – More than slight annoyance or inconvenience.
- Unreasonableness – Balancing test: gravity of harm vs. utility of D’s conduct.
- Standing – P must have a possessory interest (owner or lawful occupant).
Examples:
- D’s factory emits constant noise and smoke that disrupt P’s home life.
- Neighbor’s backyard party lights and speakers keep P awake every night.
- D’s leaking chemicals seep into P’s garden.
Exam Tip: Private nuisance = interference with enjoyment of your land.
Trespass = interference with possession (physical invasion).
Public Nuisance
Rule:
Public nuisance is an unreasonable interference with a right common to the general public, such as health, safety, peace, comfort, or convenience.
Elements:
- Unreasonable Interference – Affects the public at large.
- Public Right – Concern must involve communal interests (not just one landowner).
- Standing to Sue:
- Usually the government brings the claim.
- A private individual may sue only if they’ve suffered special damage distinct from the general public.
Examples:
- A factory dumps waste into a river used by the whole town.
- D blocks a public highway with debris.
- D runs an illegal business that endangers community safety.
Exam Tip: If the harm is widespread — like blocking access, polluting air or water, or endangering public health — it’s public nuisance.
Special Injury Requirement (Key Exam Issue)
This is the most tested distinction.
Even if a condition is a public nuisance, a private plaintiff can sue only if they’ve suffered a special injury — meaning a harm different in kind (not degree) from that suffered by the general public.
Example:
- D’s pollution affects the entire town’s air (public nuisance).
- P’s adjacent property suffers crop damage (unique harm).
- → P has special injury and can bring a private action.
Without special injury, only the state or local government can sue to abate the nuisance.
Overlap Between Public and Private Nuisance
Some conduct can be both public and private nuisance if it harms both an individual’s use of land and public rights.
Example:
A chemical plant emits toxic fumes:
- P can claim private nuisance (interference with their property use).
- The city can claim public nuisance (harm to public health).
Exam Tip: Always check whether the same conduct supports both claims — and analyze standing for each separately.
Remedies
Private Nuisance:
- Damages for loss of enjoyment or property value.
- Injunction if monetary relief is inadequate.
Public Nuisance:
- Injunction or abatement (often sought by government).
- Private damages only if P shows special injury.
Balancing Factors for Injunctions:
Courts weigh utility of D’s conduct (social value, cost to fix) against harm to P.
Defenses
- Coming to the Nuisance: Not an absolute defense — D can’t avoid liability just because P moved near the interference, but it’s relevant to reasonableness.
- Legislative Authorization: Some regulated activities (e.g., utilities) are privileged unless conducted negligently.
- Statutory Compliance: Evidence of due care but not an automatic defense.
- Contributory Negligence: Rarely applies — nuisance focuses on D’s conduct.
Exam Tip: The strongest defense is showing the interference is reasonable given social utility — e.g., a factory essential to the community.
Quick Recap
Private Nuisance:
- Substantial, unreasonable interference with P’s use/enjoyment of land.
- Individual right.
- P must have possessory interest.
- Remedy: damages or injunction.
Public Nuisance:
- Unreasonable interference with public health, safety, or comfort.
- Collective right.
- Brought by government (or private P with special injury).
- Remedy: injunction or abatement.
The Hypo
D operates a recycling plant that emits constant noise and foul odors. The entire neighborhood is affected, but P’s house next door also suffers property damage and health issues.
Result:
- Public Nuisance: The plant interferes with the community’s comfort and health.
- Private Nuisance: P has substantial interference with their own land use.
- Special Injury: P’s unique health and property harm gives standing to sue privately.
Pro Tips
- Always ask: Who is harmed — one person or the public?
- Public nuisance = collective rights; Private nuisance = individual property rights.
- Mention “special injury” for standing every time — it’s the most graded issue.
- Don’t confuse nuisance with trespass — nuisance = intangible invasion (smoke, noise, odor).
- Include “reasonableness” language — nuisance is always a balancing test.
