The short answer
A self-storage facility with 200–500 units and no dedicated security presence will average one to three reported break-in incidents per month. Most are preventable with either a mobile patrol contract (2–4 drive-through checks per night, ~$59.68/hr on Calvis) or a static gate guard during peak-risk hours. The right choice depends on your unit count, vehicle/boat/RV inventory, and how much of your occupancy is climate-controlled. This guide covers both options with real rates and a sample monthly budget.
Why self-storage facilities are high-risk targets
Storage facilities look like low-risk assets from the street. That perception is the problem. Criminals know:
- •Units hold high-value, insurance-covered property. Electronics, tools, furniture, and business inventory are common. Vehicle bays hold RVs, boats, and motorcycles worth six figures.
- •Occupants visit infrequently. A unit can be compromised for days or weeks before the tenant notices.
- •Facilities run lean on staff. Most have one or two on-site employees during business hours and no one after close.
- •Camera systems have gaps. Standard CCTV covers entry/exit lanes well but leaves interior rows, rooftops, and vehicle lots undermonitored.
The result is a predictable set of incident categories that drive insurance claims and tenant churn every year.
Unit break-ins
Bolt cutters defeat cheap padlocks in under 10 seconds. Thieves work rows quickly, hitting multiple units in a single entry. Some cut through adjacent unit walls to avoid the lock on the target unit entirely. Units with thin corrugated steel walls are particularly vulnerable to this lateral breach.
After-hours trespassing
Homeless encampments, unauthorized overnight vehicle camping, and teenagers using the facility as a gathering spot are common at facilities without after-hours presence. These incidents create liability exposure (slip-and-fall, assault), property damage, and complaints from paying tenants.
Vandalism
Graffiti on roll-up doors, broken outdoor lighting, and damage to keypad entry systems average $1,200–$3,800 per incident in repair costs once labor is included. Vandalism that compromises a unit's structural integrity can also trigger tenant theft claims that fall on the facility.
Tenant disputes and unauthorized access
Former tenants locked out for non-payment sometimes attempt re-entry. Active tenants occasionally try to access rows or units outside their authorization. Without someone physically verifying credentials at the gate, these situations escalate into confrontations that staff are not equipped to handle.
Vehicle, RV, and boat storage theft
Outdoor vehicle storage is among the highest-theft segments in self-storage. Boats and RVs are difficult to relocate quickly, but catalytic converters, batteries, outboard motors, and trailer accessories are stripped in under 20 minutes. Facilities offering vehicle storage lose that revenue tier fast after a single publicized incident.
What storage facility security guards actually do
Gate and access control enforcement
A static gate guard verifies that every vehicle and person entering the facility is an authorized tenant. They check gate codes against tenant records, turn away locked-out former tenants, and document every entry and exit. This single function eliminates tailgating, one of the most common breach methods at unstaffed facilities.
After-hours patrol
Guards on overnight or evening shifts walk or drive the interior rows on a structured schedule, checking for:
- •Unsecured or damaged roll-up doors
- •Cut padlocks or evidence of tampering
- •Unauthorized individuals on the property
- •Vehicles parked in non-storage areas
Patrol frequency matters. A guard who walks the same route at the same time each night provides minimal deterrence. Randomized patrol intervals, documented in shift reports, are far more effective.
Camera coordination
On-site guards extend the value of your existing CCTV investment. They can respond immediately when cameras detect motion in an unoccupied row, verify alarm triggers, and confirm whether an alert is a real threat or a false positive. This cuts false-alarm fees from monitoring companies and reduces police response delays from low-priority dispatches.
Lock checks
A structured lock-check means the guard physically verifies that every unit in a section is secured at least once per shift. This catches tenants who left units open accidentally, identifies tampered hardware before it becomes an entry point, and creates a written record that your facility is actively managed, which matters in tenant insurance disputes and liability claims.
Tenant verification and dispute de-escalation
Guards verify tenant identity and access credentials without escalating routine interactions. When a dispute arises, a former tenant attempting entry, a disagreement over a lien-sale unit, or an altercation between tenants over shared space, a guard on-site can de-escalate without involving law enforcement for every minor incident.
Mobile patrol vs. static gate post: which is right for your facility?
This is the most common decision storage operators face when adding security for the first time.
| Factor | Mobile Patrol | Static Gate Post |
|---|---|---|
| Best for | Low-to-medium incident facilities, 100–400 units | High-traffic facilities, vehicle storage, 400+ units |
| Coverage model | Drive-through checks, 2–6 per night | Continuous presence at entry/exit point |
| Average rate (Calvis) | ~$59.68/hr | ~$29.60/hr (unarmed) |
| Monthly cost (8 hrs/night) | ~$1,440–$1,600/mo (shared route) | ~$7,100/mo (dedicated post) |
| Deters opportunistic crime | High | High |
| Deters organized crime | Moderate | Moderate–High |
| Ideal for vehicle/RV lots | Yes (wider coverage area) | Only if gate controls vehicle access |
| Response time to incident | 5–15 min | Immediate |
Low-incident facilities, those with fewer than two incidents per year, no vehicle storage, and a well-lit perimeter, typically get the best cost-to-coverage ratio from mobile patrol. A guard visiting two or three times per overnight shift is enough to deter opportunistic crime without the overhead of a full-time post.
High-traffic or vehicle-storage facilities, those with premium RV/boat bays, climate-controlled units with high-value inventory, or a documented pattern of incidents, benefit from a dedicated gate guard. The continuous presence closes the gap that mobile patrol leaves between checks.
Many operators start with mobile patrol and add a static post on weekend nights when incident rates peak, then scale from there based on their incident log.
What does security cost for a self-storage facility?
Here are real rates from Calvis and sample monthly budgets for three common facility profiles.
Current rates on Calvis
| Service Type | Rate |
|---|---|
| Unarmed static guard | ~$29.60/hr |
| Mobile patrol (per-hour) | ~$59.68/hr |
| Armed guard (high-value vehicle lots) | ~$38.21/hr |
Sample monthly budgets
Small facility (under 200 units, low incident history)
- •Mobile patrol: 4 checks/night × 1.5 hrs × 30 nights = 180 hrs
- •Estimated cost: ~$1,740–$1,900/mo
- •No contract required on Calvis, book shift-by-shift
Mid-size facility (200–400 units, occasional incidents)
- •Weeknight mobile patrol + weekend static gate guard
- •Mobile patrol: 5 nights/week × 3 hrs = 60 hrs/mo → ~$3,580
- •Static post: 2 nights/week × 8 hrs = 64 hrs/mo → ~$1,893
- •Total: ~$5,470/mo
Large facility or vehicle storage (400+ units / RV-boat lot)
- •Dedicated unarmed gate guard, daily 6pm–2am shift
- •8 hrs/night × 30 nights = 240 hrs/mo → ~$7,104/mo
- •Optional second patrol guard on weekend overnights: +$950–$1,200/mo

How to hire security guards for your storage facility
Step 1: Run an incident audit. Pull the last 12 months of police reports, camera incidents, and insurance claims. Categorize by time of day and location within the facility. This tells you whether you need a gate post, interior patrol, or both, and at what hours.
Step 2: Choose service type. Mobile patrol for prevention-focused coverage; static gate post for access control and immediate response. Most facilities with vehicle storage need at least one static overnight shift on weekends.
Step 3: Specify armed or unarmed. Unarmed guards are appropriate for the vast majority of storage facilities. Armed guards make sense if your vehicle lot stores high-value assets or your facility has a documented history of armed criminal activity.
Step 4: Define shift requirements. Most storage incidents happen between 10pm and 4am. A targeted overnight coverage window is usually more effective, and more cost-efficient, than 24/7 staffing.
Step 5: Book on Calvis. Post your shifts on Calvis, review pre-vetted agencies competing for your job, and confirm coverage. No long-term contract required. Scale up or down by the shift as your needs change.
Comparing guard coverage to camera-only security
Camera systems catch what happens. Guards prevent it. The two work best together, but if your facility is choosing one layer to invest in first, the data favors guards for active deterrence:
- •Camera footage is primarily useful for prosecution after the fact, not prevention
- •Motion-alert systems generate high false-positive rates that desensitize staff and slow police response
- •Camera coverage gaps (interior unit rows, rooftop access, vehicle lot corners) are common at most facilities
- •A uniformed guard on-site changes criminal target selection in a way that camera signage does not
If you already have cameras, a mobile patrol contract that links guard patrol logs to your camera timestamps creates a stronger audit trail and a more defensible liability position if a tenant claim goes to court.
