Proposition U was a ballot initiative for the city of Los Angeles. Proposed by Zev Yaroslavsky, Joel Wachs, and Marvin Braude, and placed on the ballot in November 1986, Prop. U aimed to slow development in the city. Voters approved Prop. U by a 2-1 margin.
Prop. U aimed to slow the development of high rises in the city. While the downtown business core was exempt from Prop. U, the proposition established density levels for other areas of the city. Prop. U also specifically reduced the allowable size of new buildings on 70-85 percent of the commercial and industrial areas of Los Angeles by one-half.
Supporters and critics
Prop. U was supported by local political groups, such as Not Yet New York. Although Prop. U had no organized opposition, critics included developers and members of the city council, who argued that the measure would cost jobs. In an opinion piece for the Los Angeles Times, one critic called the measure too broad.
Prop. U is still considered a core rule by which builders in the Los Angeles area have to abide when constructing new buildings.
