Office building security guards manage lobby access, screen visitors, enforce tenant safety policies, and respond to incidents. The result is fewer unauthorized entries and a safer environment for everyone from the front desk to the top floor.
What office and lobby guards actually do
A lobby security officer is not just a greeter. Their presence signals that the building is monitored and managed.
Reception and lobby presence
Guards stationed at the front desk create an immediate deterrent. They greet tenants, acknowledge visitors, and hold a professional posture that discourages opportunistic theft and unauthorized entry in ways an unstaffed lobby cannot.
Visitor management and badging
Every visitor should be logged, verified, and issued a credential before proceeding past the lobby. Guards collect government-issued ID, confirm the tenant being visited, and issue temporary badges or visitor passes. Digital visitor management systems let guards cross-reference watch lists and alert property management about repeat visitors or flagged individuals.
Access control enforcement
Guards enforce access control at entry points, making sure only badged employees and credentialed visitors pass through turnstiles, elevator banks, or restricted floors. They monitor door-prop alarms, stop tailgating (when an unauthorized person follows a badged employee through a secured door), and escort anyone who cannot verify their access.
Package and mail handling
High-volume office buildings receive hundreds of deliveries daily. Guards verify courier credentials, accept packages on behalf of tenants, and keep a chain-of-custody log. This stops theft from common areas and keeps deliveries properly routed.
Tenant safety and conflict de-escalation
Guards respond to disturbances in common areas: lobbies, parking garages, shared amenities. They de-escalate confrontations, assist tenants in distress, and coordinate with building management on safety concerns like harassment complaints or suspicious individuals. In multi-tenant buildings where different companies share floors, this becomes a regular part of the job.
After-hours patrol
Evening and overnight guards run regular rounds through stairwells, parking structures, mechanical rooms, and empty office floors. Patrols follow a documented schedule logged via guard tour wand or mobile app, creating an auditable record that deters vandalism and surfaces issues like water leaks or unsecured server rooms.
Incident response and emergency coordination
When something goes wrong, your lobby guard is the first trained responder on scene. They contact 911, execute evacuation procedures, secure elevators, and brief arriving first responders. Guards with CPR/AED certifications add meaningful life-safety capability beyond what building staff can provide.
Business-hours vs. 24/7 coverage
The right coverage model depends on your building's occupancy patterns, risk profile, and budget.
| Coverage Model | Best For | Typical Hours |
|---|---|---|
| Business-hours only | Class A/B offices with low overnight traffic | Mon–Fri 7 AM – 7 PM |
| Extended coverage | Buildings with early/late workers, retail ground floor | 6 AM – 10 PM, 7 days |
| 24/7 single post | Mid-rise with overnight deliveries, parking risk | Around the clock |
| 24/7 multi-post | High-rise, mixed-use, government tenants | Multiple officers per shift |
A standard Class B office building in a suburban market will typically run business-hours coverage five days a week. A downtown high-rise with hundreds of tenants, underground parking, and ground-floor retail generally requires 24/7 staffing.
The cost difference is real. A business-hours post (roughly 60 hours/week) runs about $1,776/week at Calvis rates. A 24/7 post (168 hours/week) runs approximately $4,973/week. See the full 24/7 security guard cost breakdown for detailed math.
Static post vs. patrol: multi-floor and multi-tenant buildings
Single-tenant low-rise buildings can often be secured with one static post at the lobby entrance. Multi-floor and multi-tenant buildings need more deliberate coverage design.
A static post means one guard assigned to a fixed location, almost always the lobby. This gives you maximum visitor control and access enforcement but leaves upper floors, stairwells, and parking structures unmonitored except by camera.
A roving patrol adds one or more guards who walk circuits through the building on a defined schedule. For a 10-story building, a single patrol guard can cover every floor and the garage in roughly a 45-minute circuit while a static officer holds the lobby.
Recommended model for multi-tenant offices:
- •Buildings under 100,000 sq ft: 1 static lobby post during business hours; extend to patrol-only overnight
- •100,000–300,000 sq ft: 1 static lobby + 1 roving patrol during peak hours
- •300,000+ sq ft or government/financial tenants: dedicated security operations center, multiple posts, and documented patrol schedules
What does office building security cost?
Calvis unarmed security guards are priced at approximately $29.60/hr, a transparent all-in marketplace rate with no hidden agency markups.
Sample budget: single lobby post
| Coverage | Hours/Week | Weekly Cost | Monthly Cost |
|---|---|---|---|
| Business hours (M–F, 8 AM–6 PM) | 50 hrs | ~$1,480 | ~$6,413 |
| Extended (M–F 7 AM–8 PM + Sat) | 70 hrs | ~$2,072 | ~$8,978 |
| 24/7 single post | 168 hrs | ~$4,973 | ~$21,549 |
Sample budget: mid-rise multi-tenant building (2 posts)
| Coverage | Setup | Monthly Estimate |
|---|---|---|
| Business hours, 2 officers | Lobby static + 1 rover | ~$12,826 |
| 24/7, 2 officers | Lobby + patrol around the clock | ~$43,098 |
These figures use the Calvis unarmed rate. Armed guards or markets with higher prevailing wages (New York, San Francisco, Chicago) will cost more. Use the security guard cost guide to model your specific scenario.
No long-term contracts required on Calvis. You can book a guard for a single shift, cover a gap when your regular agency is short-staffed, or build a recurring schedule, all on the same platform.
How to hire office building security guards
Step 1: Define your coverage needs
Audit your building before reaching out to any provider. Note the number of entry points, floors, tenants, operating hours, parking structure, and any prior incidents. This shapes the post structure and hours you'll need.
Step 2: Decide on guard type
Most office buildings use unarmed guards for lobby and access control. Armed guards are appropriate when the building houses financial institutions, government agencies, pharmaceutical storage, or has had violent incidents. Expect armed rates to run 30-50% higher.
Step 3: Review licensing and vetting
Every guard assigned to your building should hold a valid state security license, have passed a background check, and completed the required pre-assignment training hours for your state. On Calvis, every guard is pre-vetted before they appear on the marketplace, so you're not chasing certificates yourself.
Step 4: Book and onboard
Provide site-specific post orders before the first shift: access routes, tenant contacts, emergency procedures, camera system basics, and building policies. A well-briefed guard performs noticeably better than one who shows up cold.
Step 5: Monitor and adjust
Review incident reports, visitor logs, and patrol completion records monthly. If coverage gaps emerge, whether from high call-out rates or skill mismatches, Calvis lets you swap shifts or adjust your booking without contract penalties.
Why property managers use Calvis
Traditional security agencies require 90-day contracts, charge opaque markups, and deliver inconsistent staffing. Calvis is a multi-agency marketplace, which means:
- •Real rates, no surprises: the price you see is what you pay
- •Vetted guards: background-checked, licensed, and rated by prior clients
- •Book by shift: cover a one-day event or set up a recurring weekly schedule
- •No long-term contracts: scale coverage up or down as occupancy changes
