Bundoora Updates Zoning Rules: New Height Limits Reshape Home Building

Bundoora sits within the Banyule City Council area, where residential development is governed by a tiered system of zoning rules that determine how high buildings can rise and how much land must remain garden space. The predominant zones affecting local streets are the Neighborhood Residential Zone (NRZ) and the General Residential Zone (GRZ), each with distinct requirements that directly shape what homeowners and builders can do on a given property.

Height Limits and Site Coverage Vary by Zone

Under the most common NRZ designation for established streets, the maximum building height is capped at 9 metres. Properties with lots of 400 square metres or larger must also set aside 35 percent of the land as garden area, and site coverage cannot exceed 60 percent. This zone applies widely across Bundoora's older residential areas [1][2].

Higher-density areas fall under the GRZ schedules, specifically GRZ3 and GRZ4, which permit maximum heights of 13 metres (four storeys) and 15 metres (five storeys) respectively. In these zones, site coverage is allowed up to 65 percent [1][3]. The Respectional Zone (RGZ) applies to properties along main road frontages, allowing a maximum height of 16 metres and site coverage up to 70 percent, with no garden area requirement [1][4].

These height and coverage rules affect what kind of housing can be built, from single-family homes with backyards to multi-storey apartment blocks, and determine how much open space remains around new developments.

Permit Timelines for Duplex Development

For homeowners considering dual occupancy or duplex projects, typical permit timelines in Bundoora range from six to nine months, according to planning data. The initial step, responding to a council Request for Information (RFI), generally takes six to 10 weeks [1][5]. This timeline affects how long residents and investors wait before construction can begin, with implications for project budgets and rental supply.

The zoning framework means that Bundoora residents on different streets may face very different rules. A property on a main road zoned RGZ could host a 16-metre building with no required garden area, while a home on a quiet NRZ street would be limited to 9 metres and must keep more than a third of the lot as garden. These distinctions directly affect property values, development potential, and the character of individual neighbourhoods.
