1. The R-4 residential zone has been established as a district in which the primary use of the land is for multi-family residential purposes but in which office buildings and certain other uses of a semi-commercial nature may be located.

Since this zone is essentially residential in character, office buildings, rest homes, mortuaries, parking lots and other transitional uses must be developed and maintained in harmony with the residential uses.
