It’s easy to assume that empty spaces are low risk. After all, no tenants, no visitors—what could go wrong?
Plenty.
At SSP, we see it all the time: vacant commercial suites that become magnets for trespassers, theft, vandalism, and liability claims. Unoccupied spaces aren't just forgotten corners of a building—they're active security risks if left unchecked.
Here’s why vacant commercial properties need proactive security—and how to protect them the smart way.

Why Vacant Suites Are a Serious Security Concern
When a tenant moves out and a suite sits empty, you might think you're safe from typical building issues. But in reality, unoccupied spaces are vulnerable because:
-
Fewer eyes mean fewer witnesses.
Empty areas are ideal for unnoticed break-ins or vandalism. -
Doors may be left unlocked during repairs or showings.
Frequent access by maintenance crews, brokers, or cleaning staff can lead to oversights. -
Vacant spaces can attract unauthorized occupants.
Squatters, loiterers, and even opportunistic thieves often target visibly empty offices or retail units. -
Insurance policies may have fine print.
Some property policies require "reasonable precautions" for vacant units—or else claims could be denied after an incident.
Bottom line: A dark, empty space doesn't stay ignored for long.

Real Risks for Unsecured Vacant Spaces
-
Theft of copper wiring, fixtures, HVAC units, and appliances
-
Graffiti and property damage
-
Fire hazards from trespassers using unsafe heat or light sources
-
Water damage due to unnoticed leaks or vandalism
-
Increased liability if unauthorized individuals are injured on-site
And let's not forget—perception matters. An obviously neglected space can impact the reputation of the entire property and make it harder to lease other suites.

How to Secure Vacant Suites (Without Breaking the Budget)
You don’t need to turn every empty office into Fort Knox. But a few smart steps can significantly lower your risk:
🔒 1. Access Control Still Matters
Even if the suite is vacant, control who can enter—and when.
-
Use electronic locks or badge-based systems on all entry points.
-
Set up time-restricted access for brokers, contractors, and maintenance crews.
-
Immediately deactivate any old tenant credentials.
Pro Tip: Mobile access control lets you update permissions remotely without needing to rekey locks after every visitor.

🎥 2. Surveillance Isn't Just for Occupied Areas
Install visible cameras overlooking vacant suite entrances and hallways.
-
Motion detection can alert property managers if unexpected activity occurs.
-
Cloud storage ensures footage is saved even if an on-site system is tampered with.
Visible cameras also serve as a strong deterrent—many opportunistic threats will move on when they know they’re being watched.

💡 3. Light It Right
A dark corner screams “no one’s paying attention.”
-
Keep exterior and hallway lights on low-power motion sensors.
-
Ensure vacant suites have basic interior lighting—enough to discourage squatters, but not so much it signals regular use.

📋 4. Routine Patrols and Walk-Throughs
Don't wait for your security system to tell you something's wrong—build proactive checks into your maintenance schedule.
-
Include vacant spaces in guard tours.
-
Document inspections with photos or digital logs.
-
Look for signs of attempted entry, leaks, or environmental damage.

📢 5. Communicate With Brokers and Vendors
Everyone accessing a vacant unit should know:
-
Where to park and enter
-
Who to check in with
-
Their access responsibilities (no propping doors, no giving codes to others)
Having clear protocols protects you—and helps avoid accidental security lapses during showings or work.

Final Thoughts: Secure Now, Save Later
Vacant spaces may seem like downtime for property managers, but they're a critical window of risk. A little investment in security now prevents costly incidents, insurance complications, and reputation damage later.
At SSP, we help property managers create scalable, flexible security strategies for entire buildings—including the suites that are waiting for their next occupant.
Because in today’s market, every square foot deserves protection.
