R1 - Residential First Density Zone (Sections 155-156)

detached dwelling residential areas;
(3)
permit ancillary uses to the principal residential use to allow residents to work at home;
(4)
regulate development in a manner that is compatible with existing land use patterns so
that the detached dwelling, residential character of a neighbourhood is maintained or
enhanced; and
(5)
permit different development standards, identified in the Z subzone, primarily for areas
designated as Developing Communities, which promote efficient land use and compact
form while showcasing newer design approaches.
