Shed permit rules in Lowell, MA — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
In Lowell, storage sheds over 200 square feet require a building permit; sheds up to 200 square feet and 16 feet tall may sit within side and rear yard setbacks but must stay at least 10 feet from the dwelling and be anchored against wind.
The City of Lowell Development Services Office regulates storage sheds under the Massachusetts State Building Code and local zoning. Storage sheds that exceed 200 square feet require building permits. A shed measuring no more than 200 square feet in area with a maximum height of 16 feet may be located within the side and rear yard setbacks, but it must be at least 10 feet from the dwelling. A shed of up to 200 square feet is small enough that it does not require a foundation, but it must still be anchored to the ground to prevent wind-related overturning. Sheds greater than 200 square feet, or sheds that have utilities connected to them (plumbing, gas, electric, sewer, etc., as in the case of a swimming pool filter house), must be placed on a footing extending below the frost line to prevent movement due to frost action. Note that a separate City guideline for the City's permit pages references a shed no larger than 120 square feet and 16 feet in height as a structure that may be placed within side and rear yard setbacks while keeping 10 feet from the dwelling; property owners should confirm the applicable threshold with Development Services before building. Questions about shed construction should be directed to the City Development Services Office.
A shed over 200 square feet (or any shed with utility connections) built without a building permit can be cited under code enforcement, requiring an after-the-fact permit, proper frost-depth footings, or removal/relocation if it violates the 10-foot separation from the dwelling. A shed placed too close to the dwelling or improperly anchored may be ordered corrected.
