The State Building Code and the Ipswich Zoning By-law can both come into play when installing a shed. Sheds 200 square feet or less do not require a building permit. Any shed over 200 square requires a building permit, basic building plans, and a Certified Plot Plan. Sheds 150 sq' or less may be set as close as 5' from side and rear lot lines and do not require a plot plan. Sheds 600 sq' or less do not require frost protected foundations, however footings for all sheds must be a minimum of 12" deep. All sheds must be a minimum of 5' from the principal building Please feel free to contact the Building Department for more information.
