Zoning regulations can be revised or implemented to allow residents to keep chickens and bees within city or municipality limits, especially in urban and suburban areas where previous policies may have prohibited such practices (Butler 2012).
KEEPING CHICKENS in the CITY OF SAN DIEGO In January 2012 the City of San Diego amended its Municipal Code to allow residents of single family homes, community gardens, and retail farms to keep and maintain chickens. The specific regulations are located in Section 42.0709 and can be found by downloading the following: Chap 04 Art 02 Div 07, We want to make clear we are allowing it but the ordinance spells out when you can do something and the limits." The limits are now set at 12 chickens per household and one rooster. The code also requires roosters to be kept inside an enclosed coop or structure from dusk-to-dawn, to quiet the crowing.
