Zoning

R5A1

Low-Medium Density Apartment Houses District

The R-5-A-1 district, low-medium density apartment houses, is designed primarily to permit low to medium density apartment developments contiguous to one-family districts and to include other residential and residentially compatible, institutional uses. Any R-5-A-1 district would serve to buffer one-family neighborhoods from more intensive residential and certain commercial uses. The density of uses in the district is controlled by the floor area ratio (FAR) and height of buildings is limited to 5 stories as a matter of right.

Permitted uses

Include but are not limited to:

Religious facility
Housing-Group
Housing-Single unit
Housing-Multiple units
Housing-Student
Educational/school
Fire house
Library
Museum / gallery
Police station
