You do not need a permit to erect a fence if it is less than 6 1/2 feet in height. The Town of Catskill does not have an ordinance regarding fences. Just use your common sense when placing the fence in relation to lot lines. Remember that you will have to maintain the "other side" of the fence. Fences with a height of 6 1/2 feet or higher are considered buildings and will require a Building Permit and adherence to setback requirements.
