Zoning requirements are unique to each town. This should be the first place to inquire about your proposal, since all of these must satisfy certain requirements. The requirements can be viewed on the Town of Westfield Land Use Regulations Ordinances. Obtaining zoning approval is necessary before a construction permit (if applicable) can be issued, this is true for sheds, patios, fences and fire pits or any other improvements to the property.
If there are any proposed changes to the property grading then the Engineering department must be consulted as well prior to construction permitting.
A construction permit is not required for sheds that are 200 square feet or less in area*, 10 feet or less in height, and do not contain utilities, for most residential properties.
