The city planning commission may grant variances in order to prevent unnecessary hardships that would result from a strict or literal interpretation and enforcement of certain regulations prescribed by this title. A practical difficulty or unnecessary hardship may result from the size, shape or dimensions of a site or the location of existing structures thereon, from geographic, topographic or other physical conditions on the site or in the immediate vicinity, or from population densities, street locations or traffic conditions in the immediate vicinity. The power to grant variances does not extend to use regulations, because the flexibility necessary to avoid results inconsistent with the objectives of the zoning ordinance is provided by the conditional use provisions of this title.
