Subdivision in Melbourne's Inner East: Boroondara, Glen Eira & Monash — 2026 Council Guide

Overview

Melbourne's inner-eastern suburbs — Boroondara, Glen Eira, and Monash — are among the most sought-after residential areas in the country and also among the most contested battlegrounds in Victoria's housing policy debate. These are councils that have historically used planning controls to limit subdivision and density in response to community preferences for maintaining neighbourhood character. They are now at the sharp end of the state government's push to override those controls in the name of housing supply.

Understanding the current planning framework across these three councils — which zones apply, how the Neighbourhood Residential Zone restricts subdivision, what the activity centre upzoning means for specific streets, and where the state and local governments are in conflict — is essential context for anyone assessing a subdivision opportunity in this part of Melbourne.

City of Boroondara

Boroondara has become the most prominent example of council-state conflict over housing density in Victoria. The council has formally challenged the state government's housing targets and activity centre upzoning proposals on multiple occasions, calling them "rushed" and warning of impacts on heritage and neighbourhood character.

Despite this resistance, the state government has proceeded with significant planning changes that directly affect Boroondara. In April 2026, the Victorian Government applied its new "housing choice and transport zone" to Camberwell Junction — rezoning the area to allow townhouses and mid-rise apartments of 3 to 6 storeys depending on lot size and location, within the defined catchment around Camberwell Station. This was applied over council objections.

Beyond the activity centre zones, Boroondara's residential planning framework is dominated by two zone types:

• Neighbourhood Residential Zone (NRZ): Covers the vast majority of Boroondara's residential land. The NRZ limits subdivision to a maximum of two dwellings per lot (i.e., a dual occupancy, not a multi-lot subdivision creating three or more new titles). Height is limited to 8 metres (nominally two storeys). This zone was specifically applied by many inner-eastern councils to limit density.
• General Residential Zone (GRZ): Applies in areas closer to activity centres and along main roads. In GRZ, subdivision to three or more lots is possible with a planning permit, subject to meeting ResCode requirements including minimum lot sizes, setbacks, and private open space provisions.

The Heritage Overlay is also extensive in Boroondara — covering significant parts of Hawthorn, Kew, Camberwell, and Canterbury. In these areas, any subdivision proposal requires a heritage impact assessment, and demolition of existing dwellings requires a separate planning permit.

Glen Eira City Council

Glen Eira sits in a different position from Boroondara: the council has been more pragmatic about housing density, and a higher proportion of its residential land is zoned General Residential Zone (GRZ) rather than NRZ. This makes subdivision more accessible for a wider range of properties.

The most common subdivision type in Glen Eira is dual occupancy with lot boundary realignment — building two dwellings on a single lot and then subdividing to create two separate titles. With typical block sizes of 500–700 sqm in suburbs like Carnegie, Bentleigh, and McKinnon, dual occupancy subdivision is viable on many blocks without requiring exceptional planning outcomes.

Glen Eira's planning scheme provides specific guidance for subdivision:

• In the General Residential Zone, the minimum garden area provisions require that a percentage of the site be maintained as permeable ground-level open space — typically 25–35% depending on the site area. This constraint affects how many dwellings can be built before subdivision.
• In the Neighbourhood Residential Zone (which applies to lower-density precincts), the two-dwelling maximum applies as in other councils.
• The council's activity centre zones — around Caulfield, Carnegie, and Bentleigh stations — are expected to be progressively included in the state government's activity centre upzoning program, potentially unlocking significantly higher yields around transit nodes.

City of Monash

Monash is consistently cited by planning practitioners as one of the more workable inner-eastern councils for subdivision and dual occupancy applications. Its planning scheme includes a higher proportion of General Residential Zone and more recent amendments that provide clearer guidance on subdivision outcomes — reducing the uncertainty that makes some councils more difficult to navigate.

Key features of Monash's subdivision context:

• Larger lot stock: Many of Monash's suburbs — particularly Mount Waverley, Glen Waverley, and Wheelers Hill — feature lots of 700–1,000 sqm, which provides more comfortable margins for subdivision than the tighter lot sizes in Boroondara or Port Phillip.
• Activity centre planning: Glen Waverley is one of Victoria's largest suburban activity centres and is expected to be a focus for the activity centre upzoning program — potentially enabling significantly higher density development in the walkable catchment around the station.
• Clayton employment corridor: The Clayton employment precinct, adjacent to Monash University, is subject to ongoing planning work that may expand residential subdivision opportunities in surrounding streets.

The Neighbourhood Residential Zone Effect

The Neighbourhood Residential Zone (NRZ) is the single biggest constraint on subdivision yield in Melbourne's inner-eastern suburbs. Applied extensively by Boroondara and parts of Glen Eira and Monash, the NRZ limits the number of dwellings on any lot to two — preventing the three-lot or four-lot subdivisions that are possible under the General Residential Zone.

In practice, this means that a 900 sqm block in Hawthorn (NRZ) can produce at most a dual occupancy split into two titles, while a similar block in Clayton South (GRZ) could potentially support a three or four-lot subdivision with planning permit approval. The financial difference — potentially $500,000–$1,000,000 in additional lot value — is the reason property developers closely scrutinise zone maps before assessing inner-eastern sites.

The state government's 2025 planning reforms have begun to erode NRZ protections in activity centre zones, but NRZ remains fully intact in areas outside the designated catchments — which is still the majority of residential land in Boroondara, Glen Eira, and Monash.

Character and Heritage Overlays

Alongside the NRZ, Character and Heritage Overlays are the second major constraint on subdivision in the inner east. The key overlays to be aware of:

• Heritage Overlay (HO): Applies in patches across all three councils — most extensively in Boroondara's Hawthorn, Kew, and Camberwell precincts. Requires heritage impact assessment and may prevent demolition of existing dwellings as a precursor to subdivision.
• Significant Landscape Overlay (SLO): Applies to properties with significant trees or landscape character. Can limit site coverage and constrain where new dwellings on subdivided lots can be positioned.
• Design and Development Overlay (DDO): May restrict building height or setbacks in specific streets or precincts — relevant where subdivision is proposed near activity centres or main roads.

Camberwell Junction: A Case Study in State Override

The April 2026 rezoning of Camberwell Junction to the new "housing choice and transport zone" is the clearest example to date of the Victorian Government overriding local council resistance to density. Boroondara's council formally objected to the state government's latest plans for the activity centre, citing concerns about heritage overlays, neighbourhood character, and infrastructure capacity.

Despite those objections, the state proceeded with the rezoning. The new controls allow:

• 3 to 6 storey buildings in residential streets within the catchment, depending on lot size and proximity to the centre.
• Mid-rise apartments at the centre core.
• Relaxed setback and car parking requirements compared to the previous NRZ/GRZ controls.

This sets a precedent: where the state government has determined that an area should receive density uplift, local council objection is unlikely to prevent it. Property owners in and around activity centres across Boroondara, Glen Eira, and Monash should monitor the progressive rollout of this program closely.

2026 Outlook

The inner-eastern councils are in a period of genuine transition. The NRZ will remain the dominant zone in most residential streets for years to come, but the state's activity centre program is creating targeted pockets of significantly higher permitted density. The key considerations for 2026:

• Check whether your property sits within a declared activity centre catchment — even a few streets' difference can mean the difference between NRZ constraints and a six-storey permit pathway.
• Heritage Overlays will continue to be vigorously defended by both councils and community groups — expert heritage advice upfront is essential for any site affected by an HO.
• Boroondara and Glen Eira are likely to continue active advocacy against state planning changes — but as Camberwell Junction demonstrates, that advocacy has limited practical effect on the government's rollout timeline.
