B. 

Minimum requirements. In interpreting and applying this chapter, the requirements contained herein are declared to be the minimum requirements necessary for the protection and promotion of the public, safety, morals, comfort, convenience and general welfare.

C. 

Contravention. Any building or parcel of land found at any time to contravene the specific provisions of this chapter shall be deemed to be in violation thereof, except in cases where such contravention is justified either:
