What type of variance requires a higher threshold for approval within the zoning board of adjustment?

A D Variance, or a "Density Variance," is typically required when the project application seeks to deviate from the zoning ordinance in a way that fundamentally alters the character of the zoning district. This includes requests for uses that are not permitted in a given zone. Because use variances can set a precedent for future development and can significantly affect the surrounding community, they demand a higher threshold for approval.

The applicant must demonstrate a unique hardship that justifies the need for a use that goes against the established local zoning regulations. The burden of proof is higher compared to other types of variances since a use variance can fundamentally change the nature of the zone and has broader implications for future land use.

Area variances, such as C Variances (relating to dimensional standards) and other forms of C Variances, usually require a less stringent standard since they typically do not affect the inherent land use.
