Securing vacant commercial properties in Adelaide: preventing squatting, vandalism and arson
An empty building doesn’t stay empty for long, not in the way owners hope. Whether it’s an office floor in the CBD sitting between tenants, a warehouse in Port Adelaide waiting on a development approval, or an old factory in Thebarton mid-renewal, the moment a commercial site goes quiet, something else tends to move in.
We get called out to a lot of these. Usually after something’s already happened, someone’s stripped the copper, lit a fire in a back room, or a family’s set up camp in what used to be the staff kitchen. The frustrating part is almost all of it was avoidable.
This is what we tell owners, receivers and property managers when a site is about to sit empty for a while.
What we mean by “vacant property security”
It’s not one thing. It’s a mix of physically hardening the building, running alarm monitoring that doesn’t rely on the site’s own power or phone line, and having someone actually drive past and check the place on a schedule. Done properly, it stops illegal entry, squatting, asset stripping and arson during the gap between tenants, during a slow development approval, or while a sale drags on.
Why an empty building costs you more than you’d think
Leaving a site to sit there with the doors locked and nothing else feels like a reasonable, cheap option. It isn’t, and here’s why.
Copper goes first
Once someone works out a building’s empty, they come back for the wiring. They’ll rip open walls to pull copper cable, take HVAC compressor units, strip plumbing fixtures out entirely. The strange part is the damage from getting the copper out usually costs far more to repair than the copper itself was ever worth. We’ve seen a site lose four figures in scrap value and rack up five figures in wall and ceiling repairs in the same visit.
Squatters are harder to remove than people expect
An empty building is shelter. Once someone’s actually living in there, getting them out isn’t as simple as changing the locks, you’re looking at formal notices and, often, police involvement, which can drag a sale or redevelopment out by weeks or months.
Fire risk goes up, a lot
Vacant sites burn more often than occupied ones. Sometimes it’s someone lighting a fire to stay warm that gets out of hand, sometimes it’s deliberate. Either way, one fire can take the whole structure and put neighbouring businesses at risk too.
Your insurance might already be void and you don’t know it
Most commercial policies in Australia have an unoccupancy clause buried in the fine print. Leave a building empty too long without telling the insurer and putting basic security in place, and a claim for theft, fire or water damage can get knocked back entirely. We’ve had owners find this out after the fact, which is the worst possible time.
What an active security plan actually looks like
Locking the door and walking away is passive. An active plan has four parts, and they work best together rather than picked one at a time.
Harden the building itself. Steel security covers over ground floor windows and doors let light in but stop anyone getting through quickly. Temporary anti-climb fencing around loading bays and rear alleys closes off the spots people try first. Swap out standard padlocks for drill-resistant ones with chain guards on gates, a cheap padlock is basically an invitation.
Deal with the utilities before you lock up. Drain the pipes and cut the water main so a burst pipe doesn’t flood the place while nobody’s looking. Kill the non-essential power circuits to cut fire risk, but leave a dedicated circuit running for the alarm and cameras. And actually clear out the rubbish, pallets and packing material lying around, that stuff is just arson fuel sitting there waiting.
Get monitoring that doesn’t depend on the building’s own utilities. A landline alarm system is useless the moment you cut the phone line, which you probably just did in the last step. Wireless, battery powered motion sensors running on 4G keep working regardless. Solar or battery backed cameras on the main entry points, feeding straight to a monitoring centre, mean someone gets a real alert instead of finding out three weeks later.
Still send someone to actually look at the place. Insurers want to see this, and honestly so should you. Random patrols at night and on weekends, especially through industrial zones like Gillman, Port Adelaide and Wingfield where these sites tend to cluster, catch problems before they escalate. Keep a log of every check, it’s tedious admin, but it’s often the only evidence that stands between you and a denied claim.
None of the four steps above does much on its own. Fencing without monitoring just slows someone down for a night. Monitoring without patrols means you find out about a problem on camera footage instead of stopping it happening. Doing all four together is really the only version of this that works.
FAQs
Why does my insurance change the moment the building’s empty?
Because insurers know vacant buildings burn and get broken into more than occupied ones. Most policies expect you to notify them once it’s vacant and put reasonable security in place, regular checks, working alarms, that sort of thing, or the cover can lapse without you necessarily realising.
What actually stops squatters getting in?
Steel covers on the ground floor openings, anti-climb fencing around the perimeter, wireless alarms that catch entry attempts early, and patrols frequent enough that someone’s caught before they’ve settled in. Once people are living inside, it’s a much bigger problem to solve.
Is copper theft really that costly?
Usually, yes, by a wide margin. It’s less about what actually gets stolen and more about the walls and conduit getting torn open to reach it. Repairing that is where the real cost sits.
