Within the districts established by this title there exist lots, buildings, and uses which were lawful before the ordinance codified in this title was passed or amended, but which would be prohibited, regulated, or restricted under the terms of the zoning ordinance or future amendment. It is the intent of this chapter to permit these noncon-formities to continue subject to certain conditions. For the purpose of protecting the public health, safety, and general welfare, however the enlargement or alteration of such nonconformities shall be regulated. Nothing within this chapter shall be deemed to permit the continuation of a public nuisance.
