Any legal nonconforming use may be extended throughout any parts of a structure which were manifestly arranged or designed for such use at the time of adoption of this chapter in 1974. A legal nonconforming use may be changed to a use of the same classification, and, when changed to a more restrictive classification, such use thereafter shall not be changed to a less restrictive classification.

To avoid undue hardship, nothing herein contained shall require any change in plans, construction or designated use of a structure for which a building permit was issued more than 30 days prior to the effective date of this chapter and the construction of which is begun and diligently prosecuted within three months after the enactment hereof and which building shall be completed within one year of the effective date of this chapter.

In no instance, however, may such efficiency and one-bedroom apartments make up more than 50% of the total units in a multiple-family project either in total or at each phase of construction.

For all one-and-one-half-to-two-story single-family dwellings, the minimum first-floor area used for living purposes shall be 768 square feet. For all two-family and multiple-family dwellings, the minimum floor area used for living purposes in each dwelling unit shall be 900 square feet.
