## Facts

- J.C. Hadacheck owned land containing valuable clay and operated a brickyard/brick kiln on the property.
- He purchased the land when it was outside Los Angeles and away from residences, intending to manufacture bricks.
- After the area was annexed, Los Angeles enacted an ordinance making it unlawful to operate a brickyard or brick kiln within specified city limits that included Hadacheck’s land.
- Hadacheck continued operating the brickyard, was convicted of a misdemeanor for violating the ordinance, and was held in custody by the city’s chief of police.
- Hadacheck alleged the ordinance substantially reduced the value and practical utility of his property for residential use because of extensive excavations and asserted the ordinance was driven by nearby residential development interests.

## Issues

1. Whether prohibiting brick manufacturing within a defined district, as applied to Hadacheck’s brickyard, deprived him of property without due process of law under the Fourteenth Amendment.
2. Whether the ordinance denied equal protection by allegedly singling out his business, permitting similar uses elsewhere, or serving anticompetitive ends.

## Decision

- The Supreme Court affirmed the state court judgment and upheld the ordinance as a valid exercise of the police power.
- The Court held that a municipality may prohibit brick manufacturing and burning within a specified district to protect public health and comfort, even if the business is not a nuisance per se.
- The Court rejected the due process claim because the ordinance regulated the place of manufacture rather than confiscating property, and it did not clearly bar Hadacheck from extracting and removing clay for use elsewhere.
- The Court rejected the equal protection claim, concluding territorial classifications are permissible when not clearly arbitrary and claims of monopoly or improper motive were too speculative on the record.

## Legal Principles

- States and municipalities may regulate land uses under the police power to protect public health, safety, and welfare; preexisting lawful uses do not immunize property from later regulation.
- A business not a nuisance per se may be treated as a nuisance in fact and law in particular localities when surrounding conditions justify the restriction.
- Substantial diminution in property value from land-use regulation does not, by itself, establish a Fourteenth Amendment due process violation.
- Territorial distinctions in regulating uses within a city do not deny equal protection absent a clear showing that the classification is arbitrary; courts generally presume municipal good faith in such determinations.
- A regulation approaching a complete prohibition on extracting and removing the underlying resource may present a different constitutional question than a restriction on on-site manufacturing.

## Conclusion

The Court sustained Los Angeles’s district-based ban on brickyards as a permissible police-power measure, holding that limiting where brick manufacturing could occur did not violate due process or equal protection despite significant economic impact on an existing operation.
