Questions: 1. The city of Pleasanton allows only 6 female chicks as pets in a “Straight Zone” residential area. If your house is in a “Special Zone”, you are not allowed any chickens unless prior approval is made with the city. Go to the zoning website for Pleasanton, click on the area you live in. If your house is in a PUD-R-1-65 (or PUD-AG) zone, you can have up to 6 female chickens. If your house is not in a R-1-65 zone, then you are not allowed chickens unless contacting the city-zoning department. Call (925) 931-5600 if you need further assistance or want to double-check your location. http://www.ci.pleasanton.ca.us/business/planning/parcelzoningmap.asp What is your address?
