Clause 34.01 of the Victoria Planning Provisions (Commercial 1 Zone) states its purposes as: to create vibrant mixed use commercial centres for retail, office, business, entertainment and community uses; and to provide for residential uses at densities complementary to the role and scale of the commercial centre. (Department of Transport and Planning (Victoria), verified 27 Sep 2026)
What this typically means for a buyer: Housing can be part of a C1Z: the zone's purpose includes residential uses at densities complementary to the role and scale of the commercial centre. It is not a standard housing zone: whether a dwelling in this zone needs a planning permit is set by clause 34.01 and any other controls on the land. A Planning Property Report for a specific address lists the zone and overlays that apply.
Ask your conveyancer: Does a dwelling here need a planning permit under clause 34.01, and what permits apply to the current use of the property?
