How to Plan Security Guard Coverage for a Commercial Property

Commercial properties rarely face the same security concerns throughout the entire day. The front entrance may be busiest in the morning, deliveries may create added access concerns during business hours, and parking lots or loading areas may become more vulnerable after employees leave.

This means security coverage should not be based only on whether a property needs a guard. It should also consider when that guard is needed, where attention should be focused and whether continuous or periodic coverage makes more sense.

For property owners and managers in Toronto and the GTA, planning coverage around the property’s actual schedule can provide more useful protection without paying for guard hours that serve little purpose.

Direct answer: On-site security is generally more appropriate when people, entrances or active operations require continuous supervision. Mobile patrol is often better during quieter periods when a property needs inspections, lock checks or alarm response rather than a guard permanently stationed on the premises. Some properties need both at different times.

Begin With the Property’s Daily Schedule

Before deciding how many hours of security coverage are needed, look at how the property operates from the first arrival until the final person leaves.

Important periods may include:

• Employees arriving before regular business hours

• Morning visitor and tenant traffic

• Scheduled deliveries and contractor access

• Shift changes

• Evening closing procedures

• Staff walking to vehicles after dark

• Cleaning and maintenance work

• Overnight periods when the building is mostly empty

• Weekends and holidays

Incident reports, tenant complaints, access records and alarm activity can help identify when problems are most likely to happen. This provides a better starting point than automatically choosing daytime, overnight or 24-hour coverage.

Security During Opening Hours

The opening period can be more vulnerable than the middle of the workday. A small number of employees may be arriving while parking areas and entrances are still quiet. Doors, gates and service areas also need to be opened without giving unauthorized individuals access to the property.

Depending on the site, opening coverage could include an on-site guard during early arrivals or a scheduled mobile patrol that checks the property before staff enter.

The decision depends on whether someone needs to remain at an entrance or whether the main requirement is confirming that the property is safe and secure before operations begin.

Coverage During Active Business Hours

Properties with frequent visitors, deliveries, contractors or multiple tenants may need a steady security presence during the day.

An on-site guard can help manage access, monitor entrances, direct visitors, support employees and respond to problems as they happen. This can be especially useful in office buildings, commercial facilities, mixed-use properties and other locations where unfamiliar people regularly enter the building.

However, a property with controlled access, limited visitors and staff who can manage routine concerns may not need a guard for every business hour. Coverage can instead be concentrated around deliveries, busy entrance periods or known problem times.

The Closing Period Often Needs Extra Attention

Closing is more than locking the front entrance. Employees may still be leaving, cleaning crews may be arriving and contractors may be finishing work. Parking areas become emptier, while side doors and loading entrances may still be in use.

Security responsibilities during this period can include:

• Confirming that exterior doors and gates are secured

• Checking washrooms, stairwells and common areas

• Watching employee parking areas

• Managing late contractor or delivery access

• Reporting damage or maintenance concerns

• Responding to anyone remaining on the property without authorization

Some properties keep an on-site guard until closing procedures are complete. Others arrange a closing patrol after employees have left. The right approach depends on how many people remain in the building and whether immediate assistance is required.

Planning Overnight and Weekend Coverage

Once the building is closed, the need for continuous supervision may decrease—but the property can still require regular attention.

A mostly empty office or commercial building may be adequately covered by mobile patrol security. Patrol visits can be scheduled around the property’s known risk periods, opening and closing requirements or alarm-response procedures.

A property with overnight employees, valuable materials, active loading operations or recurring incidents may need an on-site guard instead. The deciding factor is whether the property can safely wait for a patrol officer to arrive or whether someone must already be present.

When 24-Hour On-Site Security May Be Appropriate

Not every commercial property requires a guard around the clock. Continuous coverage becomes more relevant when:

• The property operates 24 hours a day

• Employees, tenants or visitors are present overnight

• Access must be controlled at all times

• Incidents require an immediate on-site response

• Valuable equipment, inventory or sensitive areas need constant supervision

• Problems occur during several different periods rather than one predictable window

• Site procedures or contractual requirements call for continuous coverage

Before committing to 24-hour service, the guard’s duties should be clearly defined. Coverage is more effective when each shift has specific responsibilities, areas to monitor and procedures to follow.

Combining On-Site Guards With Mobile Patrol

The choice does not always have to be one service or the other. A combined schedule can place on-site guards where continuous interaction is needed and use mobile patrols during quieter periods.

For example:

• An office building may use an on-site guard during employee and visitor hours, followed by mobile patrol checks overnight.

• A retail plaza may use mobile patrol throughout the evening, with temporary on-site coverage during recurring problem periods.

• An industrial property may need guards during shipping and shift changes, followed by patrol checks once the facility closes.

• A mixed-use property may keep a guard at its main entrance while mobile patrol checks parking areas and exterior access points.

This approach allows different parts of the property to receive the appropriate type of attention at the appropriate time.

Information Needed to Build a Coverage Plan

A security provider should understand the property before recommending hours or staffing.

Property managers should be prepared to provide:

• Building operating hours

• Employee and tenant schedules

• Number of entrances and parking areas

• Delivery and contractor schedules

• Current alarm and camera procedures

• Recent incidents or recurring complaints

• Areas that employees or tenants consider unsafe

• Opening and closing responsibilities

• Emergency contacts and escalation procedures

• Reporting requirements

This information helps determine whether the property needs an on-site guard, mobile patrol or a schedule that combines both.

Review the Schedule After Coverage Begins

Security needs can change. Seasonal business activity, construction, tenant turnover, vacant units or repeated incidents may make certain coverage periods more important.

Guard reports should be reviewed to see when incidents occur, which areas require the most attention and whether the assigned hours are addressing the original concerns. Coverage can then be adjusted instead of remaining fixed when the property’s needs change.

Plan Security Around the Property

The most effective security schedule is built around how the property is actually used. Some locations need a guard at a busy entrance. Others need opening and closing support, overnight patrols or additional coverage during specific shifts.

Frequently Asked Questions

Can a commercial property hire security only for opening and closing?

Yes. If those are the periods when employees are most exposed or access points need to be checked, coverage can be scheduled specifically around opening and closing procedures.

Does a vacant commercial property need a full-time guard?

Not always. A vacant property may be adequately covered by scheduled patrols, depending on its location, condition, access points and history of trespassing or damage. Properties with repeated incidents may need stronger or longer coverage.

Can security hours change during the year?

Yes. Coverage can be adjusted for holidays, construction work, seasonal traffic, vacant units, special events or changes in operating hours.

How is the number of guards determined?

The number depends on the property’s size, entrances, visitor activity and assigned duties. More than one guard may be required when separate areas need to be monitored at the same time or when one person cannot safely perform all assigned responsibilities.
