Where the plan commission finds that extraordinary hardships may result from strict compliance with these regulations, it may recommend a variance of the regulations so that substantial justice may be done and the public interest secured; provided such variation will not have the effect of nullifying the intent and purpose of the official comprehensive plan of the village or these regulations. The additional financial burden or time delay resulting from strict compliance with these regulations shall not, in themselves, be considered grounds for recommending a variance. (1976 Code § 152.050)
