Shed Installation · Northwest Hills County, Connecticut
In Northwest Hills County, a Shed Installation under 200 sq ft generally does not require a building permit. At or above 200 sq ft, a permit is required.
The Northwest Hills Planning Region, formed in 2013 as one of Connecticut's county-equivalent regional planning bodies replacing the former Litchfield County government, has no independent permitting function of its own; all building and zoning permits are issued by the region's individual towns and cities. Torrington, the region's largest city, follows the statewide 200-square-foot CSBC exemption for a one-story accessory structure but separately requires Planning and Zoning approval for any shed or outbuilding (except tree houses) regardless of size, and mandates that a prefabricated shed's building-permit application include the manufacturer's data sheet showing a minimum 40-pound-per-square-foot snow load rating and 90-mile-per-hour wind rating, structural specifications tied to the region's mountainous northwestern Connecticut climate. Building permits in Northwest Hills County are handled under the Individual towns (Northwest Hills Planning Region has no ind building code (IRC Connecticut State Bu). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Rocky Hill Building Department.
