25.3.E.2 Permitted Changes in Nonconforming Use

a.  In all districts, except the Historic Core Districts, if no structural alterations are made, a nonconforming use of a structure may be changed to another nonconforming use of the same or more restrictive classification, provided that the new nonconforming use is not more intensive than the prior use, as determined by the Department of Safety & Permits. Whenever a nonconforming use of a structure has been changed to a more restrictive use or to a conforming use, such use cannot then be changed to a less restrictive use.

b.  In the Historic Core Districts, if no structural alterations are made, a nonconforming use may be changed to another use in accordance with Table 25-1: Historic Core Nonconforming Use Conversion Permissions. Nonconforming residential uses in the HMR-3 District are not permitted to convert to commercial uses.
