The purposes of the R-1-B zone are to:

  • Protect quiet residential areas now developed with detached dwellings and adjoining vacant areas likely to be developed for those purposes; and
  • Stabilize the residential areas and promote a suitable environment for family life.

The R-1-B zone is intended to provide areas predominantly developed with detached houses on moderately sized lots.
