Commercial Security Guard Services for Plazas, Business Parks and Retail Units
Written by Paul Thandi, Operations Manager, On Guard Security Ltd. — 10+ years in BC security · Updated September 2026
Commercial property has an awkward security profile. By day it is busy and open to the public; by night it is empty, full of stock and equipment, and often shared by tenants who each assume someone else locked up. A commercial security guard fills that gap by covering the whole property, including the common areas, parking and back lanes no single tenant owns. On Guard Security Ltd. provides commercial security guard services for plazas, business parks, strip retail and multi-tenant commercial buildings across Surrey, Vancouver, Burnaby, Richmond, Langley, Abbotsford and the Fraser Valley. This page covers what we do, how coverage is usually structured, and what a guard can and can’t do on your property.
Key takeaways
A commercial security guard protects business property such as plazas, business parks and retail units, focusing on common areas, access, lock-ups and after-hours checks.
The busiest risk windows on commercial property are usually closing time and overnight, when tenants have left but stock and vehicles remain.
Most sites combine a daytime or evening post with mobile patrols and alarm response overnight.
Guards have no police powers. Their authority comes from the property owner, plus the arrest power the Criminal Code gives any person in narrow circumstances.
On Guard Security Ltd. provides licensed, JIBC-trained, unarmed guards with 24/7 support from Surrey.
A commercial security guard is a licensed guard assigned to business property rather than homes. The job centres on the shared and after-hours parts of the site: entrances, loading areas, parking lots, back lanes, washrooms and service corridors, plus the moment each day when the property goes from open to closed.
Depending on the site, our commercial guards handle:
Lock-ups and unlocks. Checking that every exterior door, roll-up door and gate is secured at closing, and opening up for early tenants or trades.
Common-area patrols. Walking the plaza, parking lot and back lanes, dealing with loitering, dumping and vehicles left overnight.
Tenant support. Being the person tenants call about a suspicious visitor, a broken door or a dispute in the parking lot, and passing issues to the property manager.
Staff safe-walks. Walking late-shift employees to their vehicles on request.
Alarm and fault response. Attending when an alarm trips, checking the unit and recording what was found.
Fire watch. When a fire alarm or sprinkler system is out of service, a guard can carry out the regular fire watch rounds your fire safety plan or fire department requires.
Daily reports. A written record of rounds, incidents and maintenance issues, so the owner has one account of the whole property.
Key insight: On a multi-tenant site, the weak points are the spaces no tenant feels responsible for: the rear doors, the shared loading bay and the far corner of the lot. A property-wide guard closes that gap.
Plazas and strip retail. Neighbourhood plazas mix restaurants, services and shops with long opening hours and a shared parking lot. A visible guard helps with loitering, parking lot disputes and after-hours dumping, and helps tenants feel supported. Larger shopping centres are covered by our mall and plaza security service.
Business parks. Rows of light-industrial and flex units are busy with trucks by day and very quiet at night. Coverage here usually means patrols of the lanes and loading areas after hours and checks that roll-up doors and yard gates are closed.
Multi-tenant commercial buildings. Small office-and-retail buildings need lock-ups, a presence in shared washrooms and stairwells, and someone to deal with people sheltering in vestibules after closing, done respectfully.
Vacant or transitioning units. Empty units between tenants are easy targets for break-ins and squatting. Regular patrol checks and prompt reporting keep small problems small.
Commercial sites rarely need the same level of cover around the clock. We usually match coverage to when the site is actually at risk, which keeps the plan affordable.

A commercial security guard is not a police officer, and it’s worth knowing the limits before you write post orders. Under BC’s Trespass Act, a property owner can authorize someone to act for it, and a person who is told to leave and doesn’t commits an offence. Land posted with signs prohibiting trespass also counts as enclosed land under the Act, which is one reason clear after-hours signage helps.
The Criminal Code, section 494, lets a property owner, or a person the owner authorizes, arrest someone they find committing a criminal offence on or in relation to that property, and anyone who makes such an arrest must hand the person to police right away. That is a narrow power that every citizen has, not a police power. Our default approach is to observe, document, ask people to leave when appropriate and call police, with any further steps set out in advance in your site’s post orders. This is general information, not legal advice. Our article on what private security guards can and can’t do goes into more detail.
Key insight: A guard’s best tools on commercial property are being seen and writing things down. A clear record of repeated incidents gives owners and police far more to act on than a confrontation in the parking lot.

A commercial security guard is a licensed guard who protects business property such as plazas, business parks, retail units and multi-tenant commercial buildings. The work covers common areas, parking, lock-ups, after-hours checks, alarm response and incident reports for the owner or property manager.
What are the four types of security guards?
There is no official list of four, but guards are commonly grouped as static or on-site guards, mobile patrol guards, concierge or front-desk guards, and event guards. Commercial properties most often use static posts, mobile patrols or a combination.
What can a commercial security guard do if they see someone stealing?
Guards have no police powers. Their usual approach is to observe, document and call police. The Criminal Code allows a property owner or someone they authorize to arrest a person found committing a criminal offence on that property, but the person must be handed to police right away, and any such step should be set out in the site’s post orders in advance.
Do you offer lock-up and unlock services?
Yes. A guard can visit at closing to check that every door, roll-up door and gate is secured, and return in the morning to open up for tenants or trades. Each visit is logged so you know when the property was secured.
Can one guard cover several buildings in a business park?
Often, yes. For a business park that is quiet overnight, mobile patrol visits at varied times across all the buildings are usually more practical than a guard at each one. A busy site or one with repeated incidents may still need a dedicated post.

We used On Guard for our building while we were transitioning to our new intercom and entry system. They were always incredibly professional to deal with and the guards showed up well ahead of time and did a great job as we went through the process, which extended longer than expected. On Guard was also great at getting somebody on site the first night we needed them on very short notice. Overall, we were extremely happy with their service.
