An intangible interference with a landowner's ability to make ordinary use of property that does not involve physical entry onto the land. The interference must substantially impair typical residential or other expected activities on the affected parcel.
Neil Nair owns a home next to a plastics plant operated by Nexus Technologies. Nightly chemical smells and a constant hum force Neil to keep every window shut year-round and abandon use of his backyard patio. The odors and sound never cross the property line as physical objects yet prevent Neil from ventilating his house or enjoying outdoor space.
Nikhil Narayan has lived in his suburban house for fifteen years. A nearby hospital builds a rooftop helipad that sends low-flying helicopters directly over his backyard several times daily and nightly. The resulting noise and downdrafts repeatedly interrupt sleep and make conversation or gardening on the patio impossible during flight periods.

Nalini Narula owns a single-family home beside a sports complex. Weekend tournaments begin at dawn and produce continuous loudspeaker announcements, cheering, and honking that reach inside her bedroom and patio. The noise forces her to keep windows closed and prevents any outdoor relaxation on tournament days while the property remains quiet on non-tournament weekends.
No. The definition centers on nontrespassory invasions that impair use and enjoyment without any physical crossing of the boundary. Odors, noise, light, vibrations, and similar intangibles qualify when they substantially disrupt ordinary residential activities.

No. Coming to the nuisance may inform the reasonableness inquiry but does not automatically defeat the claim. Courts examine whether the interference remains substantial despite the plaintiff's knowledge at acquisition.
