EV Charging in Apartment Buildings - A Guide for Melbourne Owners Corporations

By August 2026, fully electric cars had reached 24.9% of Australia's new-vehicle sales - one in four. In Melbourne's middle suburbs that shows up as a wallbox on the garage wall. In the inner city it shows up as an agenda item, because an apartment resident can't just call an electrician and put a charger in: the car park is common property, the switchboard belongs to everyone, and the decision belongs to the owners corporation. This year the Victorian Government published an EV-ready guide for owners corporations to help committees handle exactly this - and since owners corporations are a core part of our commercial work, here's the practical version: what your building needs to decide, and how the electrical side actually gets built.

Why charger requests are hitting committee agendas now

The economics driving this are the ones we covered in petrol vs ev charging cost melbourne 2026: charging where you park overnight costs a fraction of petrol or public fast charging - but only if you can charge where you park. A house gets that with one dedicated circuit. An apartment resident gets it only if the building makes it possible, which is why the first EV in the car park usually triggers the whole conversation. Handled well, that first request becomes the start of a staged, building-wide plan. Handled badly, it becomes an extension lead run across a fire egress, or a private charger hung off a common-property circuit with nobody metering what it draws.

The state's new playbook - and its three questions

The EV-ready guide for owners corporations, published by the Department of Energy, Environment and Climate Action in August 2026, asks buildings to land an EV strategy before anyone buys hardware. The strategy doesn't have to mean installing chargers next month - the guide explicitly allows for proceeding building-wide, staging the works, supporting an interim solution, or deferring until circumstances change. What it does insist on is answering three questions together rather than in isolation:

• →Technical - what the building's supply, switchboard and cable paths can safely support, which charging levels are viable, and what load management unlocks
• →Commercial - who funds what under the guide's benefit principle, and how the electricity used for charging is metered and billed back
• →Legal - what touches common property, and what level of owners corporation approval the works need under the Owners Corporations Act 2006

Who pays for what: the benefit principle

The guide's cost logic is the piece that unstalls most committee conversations. Infrastructure the whole building benefits from - switchboard works, the shared cable backbone through the car park - is funded across lot owners, the same way the building already funds lifts and lobby carpet. The charger itself, the final cable run to an individual bay, and the electricity that goes into the car are the individual owner's. Owners who don't drive an EV aren't paying for the neighbours who do; they're funding common infrastructure that makes every lot EV-ready, which is increasingly a line item buyers look for.

Level 1, Level 2, and why load management is the unlock

In charging terms, Level 1 means trickle rates near what a standard outlet delivers - slow, but a legitimate interim step for buildings with low daily driving. Level 2 is the wallbox class, typically 7kW to a bay, which turns any overnight stay into a full charge. The instinct that kills projects early - "our supply could never run thirty chargers" - is usually wrong, because it prices the building's supply at its worst moment. Dynamic load management measures the building's real-time demand at the main switchboard and allocates only the spare capacity to chargers: they throttle back during the evening peak and open up through the overnight valley, when a residential building's demand collapses. Managed properly, most buildings can run a meaningful number of chargers on their existing supply - and a capacity assessment tells you the actual number instead of a guess.

• →A capacity study from the building's interval data before anyone buys hardware - the supply headroom sets the design, not the charger brochure
• →A backbone sized for staged growth, so bay thirty connects the way bay three did instead of starting from scratch
• →Dynamic load management at the main switchboard, so charging rides the overnight demand valley without threatening the building's peak
• →Per-bay metering with OCPP billing, so every kilowatt-hour lands on the owner who used it and the owners corporation never subsidises anyone's driving
• →The compliance pack your building manager actually needs: Certificate of Electrical Safety, SWMS, and as-built documentation for the OC's records

What it costs

We're not going to publish a single number here, because between supply headroom, cable distances and how many bays are served now versus provisioned for later, no honest one exists - this is exactly why the state's guide tells owners corporations to get a qualified practitioner in before deciding. What we can promise is the shape of it: the benefit principle above decides which line items sit with the building and which with the owner, and every quote we issue is fixed-price after the assessment, itemised the same way. One warning from the design side: the cheapest per-bay quote is usually the most expensive path, because a one-off charger that ignores the backbone leaves the next nine owners starting from scratch - and leaves the committee having approved a precedent it can't scale.

Apartments are where Melbourne's EV growth meets Melbourne's housing stock, and the buildings that plan now get to do this once, calmly, instead of bay by bay under pressure.
