Fences - Frequently Asked Questions
Fences – Frequently Asked Questions


Do I need a building permit?  Generally No, unless there are wetland issues, or other unusual circumstances**.

How high can my fence be?     Up to 6 ft high.  (However, if the fence is on the corner of a street the “Corner Lot Visual Clearance” Section III D.d. of the Zoning Bylaw applies.  See below*)  This measurement is taken from the lowest ground on either side of the fence.

*Section III. D. d.   Corner Lot Visual Clearance

In any district no fence, wall, hedge or other structure or planting more than 2½ feet in height above the surface of the road shall be erected or maintained within the triangular area formed by the two street sidelines and a straight line connecting points on such lines twenty-five (25') from the point of intersection.~ This requirement shall not apply to buildings in the GB1 and Industrial Districts.

Where can I place my fence?  Directly on the property line, but we advise homeowners to stay at least one foot inside their property line.

Do I have to put the “front” side of the fence toward my neighbor?  No, placing the “front” side of the fence toward your neighbor is strictly a courtesy, and not regulated by the Town.


*** These questions relate to the “standard” fence issues, any unusual circumstances should be referred to the Department of Community Development.

What size sonotubes do I need to use?  Generally 8” – 10” are sufficient.

Why do I need to anchor my shed to the ground?  To hold the structure in place and reduce the risk of collateral damage in case of high or hurricane force winds.
