Here is the
link to the Borough of Bellefonte Zoning Code .
I haven't gotten a chance to read it yet. Is the property actually in the Borough proper or outside the Borough with a Bellefonte address.
I did just find this section in the Code ~ I don't know if it would apply to the location you are looking at.
608.01 KEEPING OF FARM ANIMALS.
No person shall keep any bovine, horse, pig, hog, swine, mule, sheep, chicken,
turkey or other farm animal or maintain any pig pen, hog pen, stable, kennel or other
similar structure or building for the care and housing of such animals in the Borough.
This section shall not apply to a farm, as defined on page 8, Section 104.38, of the
Zoning Ordinance of the Borough, or to any validly existing nonconforming use, or to
my veterinary or animal hospital or similar operation legally existing and presently
operating in the Borough. ((3rd. 846. Passed 8-4-80.)
