## Facts

- A defendant operated a St. Bernard dog-breeding and boarding business on her Detroit property since about 1926, investing substantial time and money.
- Over time, the surrounding area developed into a residential neighborhood with many nearby homes.
- Neighboring homeowners alleged the operation substantially interfered with use and enjoyment of their properties through offensive odors, continual barking, rats and flies, and occasional dogs escaping and roaming.
- Plaintiffs sought an injunction to stop the operation at that location.
- The defendant denied that her operation constituted a nuisance and argued (a) longevity of the use, (b) a prescriptive right to continue, and (c) many plaintiffs moved in with knowledge of the operation (“coming to the nuisance”).
- The trial judge heard conflicting testimony and personally inspected the premises.
- The trial court found a private nuisance and ordered the defendant to cease the operation on the premises within a set period (about 90 days).

## Issues

1. Whether the defendant’s dog-breeding and boarding operation, as conducted in a residential neighborhood, constituted a private nuisance.
2. Whether the defendant acquired a prescriptive right to continue the activity despite its nuisance effects.
3. Whether plaintiffs’ moving into the area after the operation began (“coming to the nuisance”) barred injunctive relief.

## Decision

- The Michigan Supreme Court affirmed the injunction requiring cessation of the operation at that location within the specified period.
- The court upheld the trial court’s finding that the operation caused substantial, unreasonable interference with neighboring owners’ use and enjoyment of their homes.
- The court rejected the claimed prescriptive right, concluding the defendant did not prove the requisite continuous, adverse, and substantially unchanged interference for the statutory period, particularly given changed neighborhood conditions.
- The court held that “coming to the nuisance” did not bar equitable relief; the operation could be enjoined even though it predated many plaintiffs’ residences.
- The court gave substantial weight to the trial court’s fact-finding, including the judge’s personal inspection, in resolving disputed evidence about the severity and existence of the nuisance.

## Legal Principles

- A lawful activity may become a private nuisance when changes in the character of the surrounding area (such as residential development) make the activity’s effects unreasonable.
- Longevity of an activity alone does not create a prescriptive right to maintain a nuisance; the defendant must show open, adverse, continuous conditions producing substantially the same interference throughout the prescriptive period.
- “Coming to the nuisance” is not a complete defense to a private nuisance claim seeking injunctive relief; it is, at most, an equitable consideration.
- Appellate courts generally defer to a trial court’s nuisance findings when supported by evidence, particularly when the trial judge has personally viewed the premises.

## Conclusion

The court affirmed an injunction against a long-running dog-breeding and boarding operation after residential growth made its odors, noise, and related conditions an unreasonable interference with neighboring homes, holding that neither prescription nor “coming to the nuisance” prevented equitable relief.
