Mentone's Hidden Quarter: The Suburb Sitting on a Rezoning Powder Keg

The paperwork has been circulating at the Mentone Civic Centre since March, but most buyers haven't noticed. A rezoning proposal covering the low-density residential belt running south of Balcombe Road, a corridor of ageing single-fronted homes and underused light-industrial lots, is now sitting before the Planning and Development Committee, with a decision expected before the end of the third quarter of 2026. If approved, parcels currently zoned Residential 1 would transition to a mixed-use designation permitting medium-density development up to four storeys.

That change, if it comes, would remake a stretch of Mentone that has spent decades quietly ignored while activity clustered around the station precinct on Mentone Parade and the bay-facing streets above Beach Road. The southern pocket has sold at a consistent discount to the suburb's median, local agents have noted a gap in the range of 12 to 18 percent for comparable land sizes, precisely because buyers have never been able to do much with the zoning beyond a single dwelling or modest dual-occupancy.

Why the Timing Is Different This Time

Several factors have converged in the first half of 2026 to make this rezoning cycle feel less theoretical than previous rounds. The Mentone Structure Plan, updated in February by the Bayside Planning Authority, explicitly flags the Balcombe Road southern corridor as a priority growth node. The document references projected household formation rates and transit proximity, the Mentone train station sits less than 700 metres from the affected lots, as primary justifications for increased density allowances.

Meanwhile, the Mentone Village Business Association formally submitted a letter of support in April, arguing that higher residential density in the corridor would strengthen foot traffic for the Earl Street retail strip, which has seen three ground-floor tenancies sit vacant for more than six months. The logic is straightforward: more residents within walking distance means more customers for the cafes, pharmacy and independent grocers that define the village character.

Land on the affected side of Balcombe Road was changing hands for between $820,000 and $950,000 per standard block through the first half of 2026, according to property listings tracked by The Daily Mentone. Post-rezoning, comparable blocks in analogous planning transitions in comparable coastal communities have attracted developer premiums of 30 to 45 percent above pre-announcement levels, though every site carries its own variables and buyers should treat those figures as indicative, not guaranteed.

What Buyers Need to Know Before the Vote

Smart money is already moving carefully. The blocks most likely to benefit sit between Mentone Grammar's playing fields on Warrigal Road and the pedestrian underpass at Mentone station, a roughly 400-metre band where lot depths average 38 metres, enough to accommodate a four-storey development with ground-floor retail under the proposed new rules. Smaller irregular lots on the side streets feeding off Palermo Street are less certain to attract developer interest even if the rezoning passes, because site consolidation becomes complicated quickly.

Anyone watching this corridor should lodge a submission through the Bayside Planning Authority's public comment portal before the July 25 deadline. Submissions don't require legal expertise, a written statement of support or concern is sufficient, but participating in the process puts buyers on notification lists for any subsequent amendments, which can sometimes shift zone boundaries meaningfully. Several residents near the northern edge of the proposed zone have already raised concerns about transition-zone ambiguity, and boundary adjustments are not uncommon in the finalisation stage.

The Mentone Community Library on Como Parade holds physical copies of the rezoning documents every Tuesday and Thursday during its community planning display hours. For buyers who prefer direct professional advice, the Planning Institute has a referral list of certified planners with Bayside-specific experience. The committee vote, expected in September, will not be the final word, any rezoning of this scale typically requires a sign-off period that could extend into early 2027. But the window between now and that September session is when informed buyers historically secure the best basis for negotiation.
