UPDATE! Wow! That was quick! I already got a response from the zoning enforcement officer! Here is what he said:
Ms. Williams,
Backyard chickens does not require a Zoning Permit. You are correct section 585.6.i gives the requirements as they pertain to The Town of Killingly Zoning Regulations (See below).
i. Keeping of backyard chickens, provided
- Permitted on any lot in the Rural Development, Low Density and Medium Density districts, including those that are less than 80,000 sf in area.
- No more than 6 hens are kept at any one time and must be confined to the owner’s side or rear yards
- Roosters are prohibited
- Housing, enclosures and manure storage are only located in side or rear yards and must be located a minimum of 20' from side and rear property lines
- Property owners should check for any private deed restrictions which prohibit or limit the keeping of livestock on their lot.
- For the keeping of more than 6 hens or for the keeping of other types of livestock in the Rural Development, Low Density and Medium Density districts, refer to the requirements of Section 585.6g.
If you are building a new building (Shed/Coop) to house the chickens a zoning permit would be needed for the structure. Depending on the size of the structure (200 SQ FT or more) a Building Permit would be required. If you are a renter make sure you have approval from your landlord prior to moving forward. If you have any additional questions feel free to call or come in to the office.
Hello,
I was reading the zoning regulations for the Town of Killingly on http://www.killingly.org I am pretty sure that where I live is considered a Medium Density Zone. According to Regulation 410.3 it states that Medium Density development is: Existing village centers and other areas which are serviced by an operating public sewer system are designated as medium density development districts. These districts are intended to reinforce existing population and service centers.
I should be allowed to have up to 6 chickens, but no roosters according to Regulation 585.6i that states:
Keeping of backyard chickens, provided
