Summary
Carroll County only exempts small 'storable' pools, those 42 inches deep or less with non-metallic or inflatable walls, from a building permit. Any in-ground pool or above-ground pool built beyond that depth or with rigid walls needs a full building permit from the Bureau of Permits and Inspections.
Amend No. 9 to read: "Storable swimming or wading pool - those that are constructed on or above ground and are capable of holding water to a maximum depth of 42 inches, with non-metallic, molded polymer walls or inflatable fabric, regardless of dimension." Compliance with all safety standards shall apply and is subject to investigation upon a formal complaint being submitted.
