What is a 'use variance' versus a 'dimensional (area) variance' in Delaware zoning?

Explanation

A use variance allows a use not otherwise permitted in the zoning district — a very high bar requiring proof of unnecessary hardship without any reasonable return under current zoning. A dimensional (area) variance relaxes specific standards (setback, height, lot coverage) for a use that is otherwise permitted — a lower bar requiring only practical difficulty. Delaware zoning boards can grant both types of variances.
