Hawthorne City Zoning Code
CHAPTER 17
20a R-1 ZONE
§ 17.20a.010 Purpose.
The principal objective and purpose to be served by this classification and its application are to create a living environment of the highest standards for single-family detached dwellings by means of the standards and requirements set forth herein with regard to minimum lot area, lot dimensions, yards, setbacks, and open spaces required to be maintained. A related consideration for the City in establishing these standards and requirements is to more efficiently and economically design, install, and maintain public service facilities in terms of size and capacity to adequately and permanently meet the needs resulting from the intensity of land use allowed in this zoning classification.
