Hawthorne Municipal Code Ch. 17 20c. R-3 ZONE (CA)

§ 17.20c.010. Purpose.

The principal objective and purpose to be served by this classification and its application are to establish areas permitting a greater population density than is allowed in more restrictive classifications, and to permit accommodations and care for a limited number of individuals who may or may not constitute a family unit as defined in this Title while, at the same time, by means of the standards and requirements set forth herein, maintaining a desirable family living environment by establishing a minimum lot area, lot dimensions, yards, setbacks and open spaces proportionate to the size of the lot. 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.
