I am the chair of my town’s Development Review Board. One of our duties is to review and grant variance requests. In VT, there are 5 questions an applicant must answer in order to receive a variance. Those are in state statute. The actual zoning regulations themselves vary from town to town. One of the questions basically asks if there is any other way you can do your project without requiring a variance. So, even though you may think you’d be ok with being up against the back property line, your best bet is to check the setback rules and comply if it’s at all possible. If there is a reason you can’t comply, such as severe topography or how your lot is shaped, then you’d qualify for a variance, at least here in Barre Town, VT.
