A fence is a free-standing wall used for privacy or protection; it may or may not be attached to a building.
You don’t need a permit if you’re building a fence 8 feet high or lower that doesn’t have masonry or concrete pieces over 6 feet.
If you’re building a taller fence, you need a construction permit. Most fences require only a construction subject-to-field-inspection permit, which is issued over the counter, typically on the day you apply. For your permit application, you’ll need to submit an application and 2 copies of scaled plans, including 1) a site plan, 2) section and detail drawings, and 3) construction notes.
You can build fences almost anywhere on your property; they don’t contribute toward your lot coverage limit. (This limit is the percentage of your lot that can be covered by a house and other buildings, such as garages.)
Your fence height is limited to 6 feet, with an additional 2 feet of architectural features such as trellises. On a sloping site, your fence can be 8 feet high, if the average height between posts is 6 feet.
If you want to build near an environmentally critical area, such as a wetland or steep slope, there are different restrictions you must follow.
Fence drawings rarely require a professional stamp (indicating they were created by an architect or engineer). You can prepare the drawings yourself or hire a professional to help you.
