Whether noise from the defendants’ windmill constituted an actionable private nuisance.
Holding
Yes. The windmill’s persistent noise unreasonably interfered with neighboring owners’ use and enjoyment of their homes and was properly enjoined.
Reasoning
Noise alone can support a private-nuisance claim in New Jersey when it injures the health or comfort of ordinary people in the vicinity and does so unreasonably under all the circumstances. The plaintiffs bore the burden of establishing those circumstances by clear and convincing evidence.
The evidence showed that the windmill’s sound was loud, distinctive, and essentially continuous whenever prevailing winds exceeded eight miles per hour. Its 56-to-61 dBA levels exceeded the ordinance’s 50 dBA standard, and the noise was especially intrusive in this quiet coastal residential setting, where the ordinary background sounds were the ocean, birds, wind, and occasional distant boat traffic.
The duration and timing of the disturbance strengthened the nuisance claim. Because the windmill could run day and night, it invaded the quiet needed for sleep and other ordinary household activities. The plaintiffs’ testimony, supported by expert evidence, showed not mere annoyance but stress-related symptoms and substantial interference with the normal enjoyment of their homes.
The defendants’ goals—saving on electric bills and using renewable energy—had genuine utility, but that utility did not justify the harm imposed here. Less intrusive alternatives were available for reducing electric costs, and the broader social value of alternative energy did not permit a device to impose substantial health and comfort harms on immediate neighbors. On balance, the windmill’s harm outweighed its utility in this location and configuration.
