What You Need to Know About Trespassing

Jun 16, 2025
Share to:Share to X/TwitterShare to LinkedInShare to Facebook

Trespassing is unlawful and expensive for businesses. Property owners and managers constantly need to find ways to grow revenue, keep tenants happy, and uphold the brand’s reputation. How you manage trespassing can greatly affect the bottom line.

The good news is that you can do something about it. This article covers the trespassing definition, why your business needs a security solution to deter trespassing, and how you can do it.

What Is Trespassing?

Most people know trespassing means entering a property without permission. However, it’s not quite that simple. A shopping center, for example, welcomes visitors. Yet, it’s possible to become a trespasser on the retail center’s property.

Every state has its own trespassing definition. Essentially, they have the following in common per Nolo: “Intentionally entering or remaining on someone else’s property without authorization.”

Thus, a person who trespasses on a commercial property is someone who interferes with the safe operation of the business. If someone skulks in front of a retail center it will hinder business. Customers won’t feel comfortable or safe making their way into the building.

It’s possible to trespass without stepping on the property. One way to do that is to throw things onto the property or flood it. In this case, the trespasser is causing something to enter the property.

Why Trespassing Is a Concern for Businesses

Trespassing can be a gateway to vandalism, theft, dumpster diving, and loitering. Construction sites sometimes end up with crane climbers. A trespasser who gets hurt on your property could sue your company and hold you liable. It sounds illogical because the person showed up on your property without permission. It happens more than you think.

Companies and property managers have an obligation to help prevent injuries on their property. Yes, if damage occurs on your property, your property damage liability insurance pays for it and covers legal costs if someone sues you. However, here’s where it turns tricky. It can be difficult to prove who is responsible for the damage to your premises. Fortunately, there’s a solution for that.

Check out these crime statistics. The FBI’s Crime Data Explorer reveals the property crimes in 2017 took place in the following locations:

  • Parking lot and garage: 272,269 crimes (No. 2)
  • Department and discount store: 235,935 crimes (No. 3)
  • Alley, sidewalk, street, and highway: 207,994 crimes (No. 4)
  • Commercial/office building: 63,717 crimes

The No. 1 offense is destruction, damage, and vandalism of property consisting of 153,715 incidences in 2017. Next comes burglary/breaking and entering.

The Bureau of Justice Statistics reports the average number of violent crimes that took place in commercial places between 2004 and 2008 was 12 percent, or a whopping 664,700 incidences. Almost 1 million property crimes — including burglary and theft — occurred on commercial properties in the same timeframe.

Trespassing also impacts how employees, vendors, and customers feel about your business and property. If they feel unsafe, they will go elsewhere. Finding new tenants takes time and money. Searching for a new vendor who can provide what you need for the right price is a difficult process. When customers or residents leave, that’s lost revenue and it’s hard to get it back.

How can trespassing cause people to feel unsafe? They feel uncomfortable when they see property damaged, people loitering, or items stolen. No matter how hard you may try to keep things under wraps, people have a way of finding out. Fortunately, there’s a way to minimize trespassing and its high price.

How to Help Protect Your Business from Trespassers

Property owners and managers have a duty to notify outsiders that the land is private property, and no one can enter without permission. They also have a responsibility to let trespassers know about the potential hazards on the property. You or your business could be held liable if any injury occurs on your property.

The goal is to prevent a trespass situation in which you need to remove the trespasser. In doing so, you won’t have to wrangle with the law as to whether it’s legal to escort someone off the premises.

Here are three viable options to deter trespassing.

1. Fences and signs

While fences and “no trespassing” signs work well on personal private property, they don’t prevent entry, especially on business property. Besides, places like shopping centers and apartment buildings can’t always put up fences or install gates because they want visitors to enter without barriers. They can, however, post “no loitering” signs.

Another sign to consider posting is “Area under surveillance.” It can deter some potential trespassers but not those with dodgy intentions. Regardless of the fences and signs posted, thieves often trespass on construction sites.

2. Lighting

An affordable yet effective security option is lighting. It reduces or eliminates shadowy areas and hiding spaces. Lighting ensures visitors, drivers, and pedestrians can see where they’re going.

In researching lighting, you want to ensure you use the right amount of lighting and the right hue. Soft lighting does little to reassure safety and bright lights can be just as unsafe. Certain types of lights enhance security better than others. Ask your security expert for recommendations.

If you have lighting, confirm the spacing between lights. Too much space creates darker areas. Remember to install lighting in the parking area, outside of the building, parking lot stairwells, and sidewalks.

3. Remote video monitoring

Sometimes the threat is internal from employees. They know the property’s weak spots and how to exploit them. To counter this, many companies hire security guards. Human presence can be important in dealing with security threats.

Live video monitoring can enhance security solutions by working with security guards. If someone enters the property without permission, a trained monitoring operator, watching AI-enabled surveillance cameras can call the police and help them find the suspect. People watching the monitors are off-site and possibly in another city or state, thus they cannot steal or commit a crime. This eliminates internal threats.

Surveillance cameras also come in handy to decrease and even eliminate liability claims. They can help prove the business took the necessary safety precautions to create a safe environment. Car dealerships deal with many false claims. A customer can claim the dealership damaged the vehicle while in for service. The dealership video monitoring and review can show the vehicle already had damage when it arrived on the dealership’s lot.

Should a company have a healthy budget that can cover multiple security guards, their security could still need a boost. Security guards cannot always have eyes on the entire property. Remote video surveillance has the ability to watch multiple areas at the same time, which can be a cost-effective enhancement.

Moreover, security guards can only do so much when it comes to trespassing. What they can do depends on state laws, training, and licensing. “One of the most misunderstood and abused shopping center practices is how to legally handle persons that have trespassed,” writes Chris E. McGoey. He says that it’s illegal for security to detain and process a shopping center trespasser in most states.

Working with a Live Video Monitoring Company

In working with an experienced monitoring security company, you’ll rest easy knowing that trained operators watch your property through strategically placed cameras. They’ll see the greatest amount of your property compared to other solutions.

As soon as the operators spot something suspicious, they act. If the situation warrants it, they will contact the police. They can use the audio speaker system to alert trespassers they are being watched. In some cases, they call the manager to notify them of the problem that does not require involving law enforcement. They have caught problems such as the start of a flood, potential safety hazards, and debris blown all over the property.

The other benefit of remote video monitoring is that someone watches your property during extreme weather conditions. The weather has nothing on the right equipment and the operators watching your cameras. While thieves may not venture out in the snow, very cold temperatures can break something. The sooner you know about it, the less damage it will cause.

Monitoring operators can catch non-trespassers who damage property. For example, one company’s fleet truck damaged inventory during working hours. No one onsite saw it happen. The trained operator could zoom in on the truck to read the license plates and fleet number as well as identify the driver.

In another instance at an apartment complex, a kid climbed the apartment pool fence. An operator caught the kid and activated the speaker warning. The child climbed down and left before anything bad happened.

As specialists in video surveillance, ECAM has deterred many trespassing instances before damage occurred. In designing security solutions, one size does not fit all. ECAM customizes every security solution based on your industry, needs, regulations, and property.

You can view trespassing videos to see how ECAM has deterred trespassers and damage. The best security services to minimize trespassing depends on many factors. A security adviser can evaluate your property, business, and budget to make recommendations that fit your requirements. If you’d like to talk to our security specialists, please contact us.

FAQ: What is Trespassing, and Why Should You Care?

What is trespassing?

Trespassing involves intentionally entering or remaining on someone else’s property without authorization. It can occur even in places like shopping centers, where visitors are welcome, if the person interferes with the business’s safe operation.

Why is trespassing a concern for businesses?

Trespassing can lead to vandalism, theft, and other crimes. It poses safety risks, potentially leading to lawsuits if a trespasser is injured. It also affects the perception of safety among employees, vendors, and customers, which can harm the business’s reputation and revenue.

What are some common locations where property crimes occur?

According to the FBI’s Crime Data Explorer, common locations for property crimes include parking lots and garages, department and discount stores, and commercial/office buildings.

How does trespassing impact employees, vendors, and customers?

Trespassing can make people feel unsafe due to visible property damage, loitering, and theft. This discomfort can lead to a loss of tenants, vendors, and customers, ultimately affecting the business’s revenue.

What are some ways to deter trespassing on business properties?

Businesses can deter trespassing through the use of fences and signs, proper lighting, and remote video monitoring. Each of these methods helps to increase security and reduce the likelihood of trespassing.

How effective are fences and signs in preventing trespassing?

Fences and “no trespassing” signs can be effective, especially on personal property. However, they may be less effective on business properties, which often require open access for customers and tenants.

Why is lighting important for security?

Proper lighting reduces or eliminates shadowy areas and hiding spaces, making it easier for visitors and employees to see and feel safe. It also deters potential trespassers by increasing visibility.

What is remote video monitoring and how does it help?

Remote video monitoring involves trained operators watching the property through strategically placed cameras. They can detect suspicious activities and alert the police or property managers, reducing the risk of internal threats and liability claims.

Can security guards alone effectively manage trespassing issues?

While security guards can help, they have limitations. They cannot always cover the entire property and their effectiveness depends on their training and state laws. Video surveillance can be added as a comprehensive and cost-effective solution.

How can a business benefit from working with a live video monitoring company?

A live video monitoring company provides trained operators who can monitor the property continuously, even in extreme weather conditions. They can quickly respond to suspicious activities, help prevent damage, and support liability claims with recorded footage.
