Hadacheck v. Sebastian, 239 U.S. 394 (1915), was an early U.S. Supreme Court case on the constitutionality of zoning ordinances. The Court held that an ordinance of Los Angeles, California, prohibiting the manufacturing of bricks within specified limits of the city did not unconstitutionally deprive the petitioner of his property without due process of law, or deny him equal protection of the laws.
