What a Commercial Building Security Guard’s Day Looks Like

By
Amir Anvarizadeh

You’ve likely seen a commercial building security guard in action, whether they’re managing the front desk at a residential building, patrolling a retail plaza, or greeting employees at the entrance to an office building. But what exactly do they do in a day? What are their duties, and how do they safeguard a building and the people inside?

This blog covers a day in the life of a commercial building security guard, from opening its doors to locking up at the end of the day. While not every building follows the same procedures and schedules, this breakdown provides a general overview of the tasks commercial building security guards typically perform.

1. Morning: The Start of the Shift

A commercial building security guard usually arrives early to get the building prepped for the day. Some building security guards handle keyholding and are the first to arrive each day.

  1. When the guard arrives at the building, they’ll typically begin their shift by reviewing the previous guard’s reports.
  2. Next, they’ll confirm that all access control systems and CCTV cameras are up and running.
  3. They’ll perform a sweep of the building’s exterior, lobby, shared spaces, and primary entry points for anything out of place. This might include signs of vandalism, damage, litter, or vagrancy. If there are any issues, the guard will report them and either address them immediately or coordinate with maintenance teams.
  4. When the building is ready to open to the public, the guard unlocks the primary entrance and the parkade gate.

When security starts off well, the rest of the day goes more smoothly. This makes the first hour important. The guard sets the tone by making sure access points are secure, systems are working, and everything is in order before people arrive.

2. Access Control and Monitoring

As the building becomes busier with employees and visitors, the security guard focuses on access control and monitoring. Having a visible security guard on site reassures tenants and shows that the property is well-protected. At the front desk or main entrance, a commercial building security guard may:

  • Manage visitor sign-in.
  • Verify ID and credentials.
  • Monitor badge or key fob access.
  • Direct visitors or service providers to the correct floor or office.
  • Answer questions, provide customer service, and address tenant feedback or concerns.
  • Coordinate vendor and contractor arrivals.

Access control is one of the main jobs of a commercial building security guard. Guards make sure only authorized personnel enter secure areas while maintaining a welcoming environment.

3. Midday: Patrols and Oversight

Once the building is up and running and the initial morning influx of visitors has passed, the commercial building security guard keeps an eye on the entire building through a combination of CCTV monitoring and patrols.

Patrols often include:

  • Walking through corridors and shared areas.
  • Checking stairwells and parking areas.
  • Confirming access doors are secured.
  • Looking for maintenance issues, such as broken lights or surface damage.

Foot patrols often catch details that might not be as visible on CCTV cameras, so it’s important for security guards to use both methods of monitoring. Regular checks help keep building managers informed on issues as they arise.

4. Communication and Reporting Throughout the Day

Two important but often overlooked duties of a security guard are reporting and communication. When incidents occur or are found on patrol, the commercial building security guard writes a detailed report. Accurate, comprehensive reports create a clear record of what happens in and around the building.

These reports often include:

  • The date and time of the incident or when the issue was discovered.
  • Individuals involved, if any.
  • A description of the situation.
  • Actions taken.
  • Photo or video evidence, if available.

In addition to writing reports, the security guard stays in touch with building management throughout the day, sharing updates and important information in real time. This way, managers always know what’s going on in their building.

5. Managing Deliveries and Service Providers

Commercial buildings often have a steady stream of deliveries and service providers coming through their doors. It’s the job of the commercial building security guard to help keep everything organized. These duties typically include:

  • Receiving and logging deliveries.
  • Coordinating vendor access.
  • Confirming work orders with property management.
  • Directing or escorting service providers to secure areas.

Having a security guard on hand to manage these visits prevents confusion and keeps building operations running smoothly while making sure access control rules are followed.

6. How Commercial Building Security Guards Respond to Security Issues

Not every day goes exactly as planned. A commercial building security guard needs to be ready to address problems as they happen, such as unauthorized entry attempts, disagreements between tenants or visitors, rule violations, and disruptive behaviour.

Depending on the security company, commercial building security guards may be trained in communication, de-escalation, and conflict resolution. At Blackbird Security, for example, our guards are trained through our industry-leading in-house security training program, Blackbird Academy.

Our training goes beyond what’s required to earn a security guard license, and helps our guards respond to situations safely and professionally. When guards are present to respond promptly to issues, it helps maintain order in the building and improves the tenant experience.

7. Emergency Response

Emergencies can and do happen, and commercial building security guards need to understand exactly what to do ahead of time, according to the building’s protocols. Since a commercial building security guard is often the first one on scene, they need to respond calmly and decisively.

Here’s a breakdown of a typical emergency response. The guard:

  • Assesses the situation quickly.
  • Initiates building protocols.
  • Coordinates evacuations if needed (such as during fire alarms).
  • Dials 911 and communicates with first responders.
  • Provides first aid until medical personnel arrive.
  • Secures affected areas.
  • Communicates updates to property management.

A quick, organized response minimizes confusion and panic among building occupants and helps people get help as quickly as possible.

8. End-of-Shift Handover

Another important part of the security guard’s day is the end-of-shift handover, which may take place in buildings with overnight security guards. A smooth handover between guards makes sure there are no gaps in coverage. The guard will typically:

  • Brief the incoming guard on any incidents or unusual activity.
  • Flag maintenance concerns or action items to follow up on.
  • Share tenant concerns and building updates.

These steps help the next guard start their shift fully informed. Communication during shift changeovers keeps things consistent and ensures nothing gets overlooked.

9. Evening: Closing the Building

Commercial building security guards who handle keyholding duties must secure the building at the end of the day. The tasks involved in closing can include:

  • Confirming all visitors have left the building.
  • Locking entrances, exits, and secondary access points.
  • Checking that alarm systems are armed.
  • Conducting a final sweep of the lobby and shared spaces.
  • Recording any final observations in the shift report.

These closing steps help keep the building secure after hours. A careful final check ensures the building is ready for the next day.
