The laws are city by city. In Columbus there is a post that says you can have them if you go through the proper steps. Every city or community has different zoning laws. I live in a small town in Licking County just east of Columbus and the laws says they don't allow Chicken husbandry. We sent a letter to the Village challenging that we were not in husbandry as that by definition is farming for profit. We are simple the owner of Chickens as pets. We never heard back. The other laws that we ran into were the permit to have the coop. You may also have to check with the municipality on the rules for outdoor sheds or structures. BTW our girls are now 5 months old and we are getting 5 beautiful brown eggs everyday. We love our girls.
Good Luck!
I believe I live in the same area. After contacting zoning, I received this email which is an excerpt from a lawyer the zoning officer contacted for advice. It reads:
(1) Agriculture on lots of one acre or less;
(2) Buildings or structures incident to the use of land for agricultural
purposes on lots greater than one acre but not greater than five acres
by: set back building lines; height; and size;
(3) Dairying and animal and poultry husbandry on lots greater than one
acre but not greater than five acres when at least thirty-five per cent
of the lots in the subdivision are developed with at least one building,
structure, or improvement that is subject to real property taxation or
that is subject to the tax on manufactured and mobile homes under
section 4503.06 of the Revised Code.
The authority provided in R.C. 519.21 is not self-executing. Rather, the
Trustees must specifically adopt zoning amendments/regulations
addressing "agriculture" and how it will be regulated on the specified
properties.
It is my understanding that the Granville Township Zoning Resolution
does not currently regulate "agriculture" as in accordance with R.C.
519.21. As a result, the property owner that has approached you may
keep the hens on her property.
(Whether or not the property owner is subject to deed restrictions,
etc., which would prohibit the keeping of hens, is a separate matter.
And as you are aware, there is no authority for the township zoning
inspector, or the prosecutor's office, to enforce deed restrictions and
the like.)
