Strata and Multi Unit Possum Guards: Protecting Shared Power Lines

Do strata and multi unit buildings need possum guards on shared power lines? Often yes, because a single point of attachment or a shared run of overhead line can give possums access to several units at once, and the physical fix is the same guard used on a single home. What changes is the process: the line and the roof space above it are common property, so the job needs to go through the owners corporation rather than one resident booking a guard off their own initiative, and a bigger building can genuinely need more than one guard rather than a single fix for the whole block.

1. Why shared lines make a bigger target

A single point of attachment serving a whole block of units is, from a possum's point of view, simply a wider and more established highway than the equivalent line on a standalone house. More overhanging trees near a larger site, more roof area to explore, and a line that has often been in place for decades without a guard all add up to a higher chance that a possum finds and starts using it. Once it does, the same signs apply as on any home: scratching around dusk and dawn, droppings near the eave closest to the line, and a worn track along the cable, covered in more detail in our guide to signs a possum is using a power line.

2. Getting owners corporation approval before booking a job

Because the point of attachment and the roof space above common areas are common property, a possum guard on a strata building is technically a capital or maintenance decision for the owners corporation rather than a single lot owner's call, even when one resident is the one being kept awake at night. In practice this usually means raising it with the strata manager or building manager, who can often approve routine electrical maintenance under delegated authority without a full general meeting, particularly where the cost is modest and the work does not touch individual lots. Our guide to strata electrical work in Sydney covers who is responsible for what across a building in more detail, including when something needs full committee sign off rather than manager approval.

3. One guard or several: mapping the building's actual points of attachment

Older walk up blocks, especially those built before a single larger supply became the norm, sometimes have more than one separate service run feeding different sections of the building, each with its own point of attachment. A site assessment is the only reliable way to know how many guards a particular building actually needs, since assuming one guard covers everything can leave a second, less obvious access route completely open. Larger or campus style strata developments with multiple buildings on one title are the clearest case for needing several guards rather than one.

4. Access and safety for multi storey common property work

Fitting a guard on a point of attachment two or three storeys up a building is a different job to a single storey home. Depending on the height and what is directly underneath, an elevated work platform may be needed rather than a standard extension ladder, and access has to be coordinated so it does not block a driveway, a fire path or a resident's parking space during the visit. This is worth factoring into scheduling expectations when a strata manager is getting quotes, since it can affect both the cost and the notice period needed before the work can go ahead.

5. Cost apportionment: admin fund, capital works fund or special levy

Most possum guard jobs on a strata building are modest enough to sit comfortably within the administrative fund as routine maintenance, similar to any other minor common property electrical repair. Where a guard job is bundled with bigger common property electrical work, such as a broader switchboard or common area lighting upgrade, it is more likely to be treated as a capital works item and funded accordingly, and a genuinely large job across a campus style development with several buildings could justify a special levy if the capital works fund does not have the balance to cover it. Whichever fund it comes from, keeping a record of the work and any compliance paperwork protects the building if it is ever audited or sold, the same principle that applies to any other common property electrical job.

Why it's Level 2 ASP work

A possum guard fitted at or near a building's point of attachment sits on the service line itself, which is Level 2 ASP territory regardless of whether the building is a single home or a hundred unit strata block. The network's safety rules around working on or near a live service line do not relax because the job is bigger or the client is a strata manager rather than a homeowner.

How High Demand Electrical helps

High Demand Electrical is a licensed Level 2 ASP experienced in coordinating common property electrical work with strata managers and building managers, not just single homes. We map every point of attachment on a building before quoting, so a strata manager gets an accurate picture of how many guards are actually needed rather than a single line item that turns out to miss a second access route. As one of Sydney's most trusted Level 2 ASPs for private power pole and service line work, we plan access, timing and any equipment needs around the building's occupied common areas, not the other way around.

If residents are reporting possum activity and the line involved is common property, get a strata possum guard assessment from High Demand Electrical or call 0402 559 777. Every job starts with a site visit so the scope and any access requirements are confirmed before a quote is issued.
