Generally, the owners corporation is responsible for electrical repairs involving common property, while a lot owner is usually responsible for electrical equipment and wiring that belongs to or exclusively serves their individual lot.

However, strata electrical responsibility is not always as simple as asking where the fault occurred.

The registered strata plan, the building’s by-laws, where the electrical infrastructure sits and what it supplies can all affect responsibility.

That means the first job is often to identify where the electrical fault actually is.

MPV Group provides Strata Services Sydney for apartment buildings, unit blocks and managed properties, including electrical fault finding, repairs, switchboards, lighting and shared electrical infrastructure. MPV’s strata service offering is specifically structured around common areas, units and shared systems.

MPV Group has provided electrical services across Sydney since 1992, and strata electrical faults often become confusing because the symptom appears in one apartment while the cause sits somewhere else in the building.

For example, a resident may lose power inside their unit, but the problem could be in the apartment’s own circuit, its switchboard, a supply cable or shared building infrastructure.

That is why determining who should pay often comes after determining what has actually failed.

A licensed strata electrician can investigate the electrical fault and provide information about the affected equipment, which can then help the owner, strata manager or owners corporation determine responsibility.

Electrical infrastructure forming part of common property is generally maintained by the owners corporation. In practice, this can include electrical systems serving shared areas or multiple lots, such as main building switchboards, common-area electrical infrastructure and shared lighting.

Hallways, foyers, stairwells, car parks and other shared spaces are typical examples where electrical repairs are handled as strata building maintenance. MPV Group’s Strata Electrical, Solar & Security Upgrades Sydney service covers this broader shared-building infrastructure.

The exact boundary should still be checked against the particular strata plan and by-laws rather than assumed. Industry guidance similarly notes that responsibility can change depending on the lot boundaries and the specific scheme.

Electrical items located within and exclusively servicing an individual apartment are often the lot owner’s responsibility.

Depending on the strata scheme, this can include internal power points, switches, light fittings and electrical circuits that exclusively serve the individual lot.

A fault affecting only one apartment does not automatically prove that the owner is responsible, though.

The electrician may need to determine whether the problem is within the apartment’s own electrical installation or further upstream in shared infrastructure.

Recent NSW strata commentary, for example, identifies internal fuse boards and wiring exclusively serving one lot as commonly falling to the individual owner, subject to the particular strata plan and by-laws.

It depends on which electrical wiring has failed and what that wiring serves. This is one of the most common areas of confusion.

A cable supplying shared building services or multiple lots may form part of common electrical infrastructure, while wiring dedicated to one individual lot may fall to that owner.

The location of the cable alone may not provide the complete answer. If responsibility is unclear, the best sequence is:Locate  the fault → Identify what the wiring serves → Check the strata plan and applicable by-laws → Determine responsibility.

That is much more reliable than deciding who pays before an electrician has identified the actual fault.

It depends on whether the switchboard is shared building infrastructure or serves an individual lot.

A main switchboard supplying the strata building is very different from a distribution board exclusively servicing one apartment.

If the building’s shared switchboard is ageing, damaged or no longer suitable, the owners corporation may need to consider repair or a broader Switchboard Upgrade Sydney.

MPV Group provides switchboard work across residential, commercial and strata properties, including assessment of load demand and shared electrical infrastructure.

Common-area lighting is generally a strata responsibility because it serves shared parts of the building.

This can include lighting in hallways, foyers, car parks, stairwells, pathways and building entrances. A single failed fitting may simply require repair or replacement.

Where lighting faults are recurring across the building, it may be worth assessing the circuits, controls and existing lighting infrastructure rather than repeatedly replacing individual fittings. MPV Group provides Lighting Installation Sydney for strata common areas as well as residential and commercial properties.

First determine why the apartment has lost power. A power outage affecting one unit could originate from an appliance, internal circuit, safety switch, apartment switchboard or another electrical fault.

If several apartments or common areas lose power simultaneously, the problem may involve shared building infrastructure or the electricity network.

This is why a power outage should be diagnosed before responsibility is assigned. MPV Group’s Electrical Fault Finding Sydney service is designed to identify whether a problem sits within one circuit, an apartment or the broader electrical system.

A fault affecting only one apartment may be the owner’s responsibility, but not always.Where a faulty power point, light fitting or internal circuit exclusively serves that apartment, the repair may fall to the lot owner.

However, the symptom could still originate from electrical infrastructure outside the apartment.

For example, losing power to one unit does not by itself establish where the failed electrical component is located. The electrician should find the fault first. Then responsibility can be considered.

If multiple lots or common areas are affected, shared electrical infrastructure becomes more likely to be involved.

That could point towards a building switchboard, shared distribution system or another common electrical component.

This is where engaging a contractor experienced in strata electrical work becomes especially useful because the fault needs to be considered at a building level rather than as several unrelated residential call-outs.

MPV Group’s Electrical Services Sydney include fault finding, repairs, switchboards and electrical upgrades across strata as well as residential and commercial properties.

Responsibility usually depends on what caused the emergency and which part of the electrical system requires repair.

For example, an urgent fault in common-area electrical infrastructure may fall to the owners corporation, while an electrical fault entirely within one owner’s lot may be that owner’s responsibility.

However, an electrical safety issue should not be left unresolved while everyone debates the invoice.

If there is a burning smell, exposed wiring, switchboard failure, significant power loss or another immediate electrical risk, the priority is to make the situation safe and identify the fault. MPV Group provides Emergency Electrician Sydney services for residential, commercial and strata electrical faults.

Sometimes a repair call-out uncovers an issue that goes beyond the original fault.

An electrician may find that the shared switchboard is ageing, circuits are repeatedly overloaded or existing electrical infrastructure is no longer suitable for the building’s requirements.

At that point, the strata committee may need to consider whether continuing with repeated repairs makes sense or whether a planned Electrical Upgrade Sydney is more appropriate.

For older apartment buildings, this can also help the owners corporation plan future requirements such as air conditioning, additional electrical loads and EV charging.

An upgrade requested for the benefit of one apartment is different from repairing existing common property.

For example, an owner may want additional electrical capacity, air conditioning or an apartment EV charger. The existing building infrastructure may be perfectly functional, but the owner wants to add something new.

Who pays and what approvals are required can therefore differ from a normal maintenance repair.This distinction is particularly important as strata buildings receive more requests for Strata EV Charging Sydney.

The most useful first step is to get clear information about the fault. Is one apartment affected or several? Are common areas affected? Is there a burning smell, sparking or power loss? Has the problem happened before?

A strata electrician can then investigate the problem, identify the affected electrical infrastructure and provide a clear repair scope.That makes it much easier for the strata manager or owners corporation to determine the next step.

With strata electrical repairs, the symptom and the cause are not always in the same place.

• A light not working inside an apartment may be a simple lot-owner repair.
• A power problem affecting the same apartment might originate elsewhere.
• A common-area lighting problem may be a single failed fitting or evidence of a larger circuit fault.

The best approach is:Diagnose first. Allocate responsibility second.
