Types of zoning reviews. For purposes of general understanding, a permitted use or structure is allowed in a zone district; it does not require discretionary review or approval by a Town Board. Permitted uses may require a building permit or certificate of occupancy for certain activities. A variance is a waiver request of the applicable use or dimensional controls and requires Zoning Board of Appeals review and approval. Site plan or special permit reviews are uses or structures which are allowed but due to their nature, necessitate discretionary board review over, but not limited to elements of size, site design, intensity of use and character. To determine type of review for a specific use or structure consult the Article III, Zone Districts, and Article IV, Supplemental Regulations.
