If you’re a property manager, business owner, or commercial landlord in California, chances are you’ve faced the challenge of homeless encampments on or near your property. With recent changes to California trespassing laws in 2025, more tools are available to help you take legal action—but enforcement is only half the equation.
To truly reclaim your space and keep it secure, you need a strategic security plan that transforms high-risk areas into protected zones. This isn’t just about removing people—it’s about preventing future occupation through smart, physical deterrents and consistent oversight.
In this article, we’ll show you how to protect your business from homeless encampments in California, using practical steps backed by over 30 years of on-the-ground security experience.
Why Encampments Return (and What to Do About It)
You clean up, you fence off, you call the city—and yet, a few days or weeks later, the encampments return. Why?
Because most businesses only address the symptom, not the cause. Unless a space is permanently transformed, it remains vulnerable. Common traits that attract encampments include:
- Poor lighting or visibility
- Gaps in fencing or access points
- Lack of signage or enforcement presence
- Empty or inactive spaces (vacant lots, alleys, underpasses)
The good news? These vulnerabilities can be fixed. And with the right approach, you can reclaim your space—and keep it that way.
Step 1: Secure the Perimeter with Fencing and Access Control
Physical barriers send a strong first message: this property is protected.
- Use tall, anti-climb fencing for vulnerable zones
- Seal off access gaps—especially behind buildings or near dumpsters
- Install tamper-resistant locks or gates for service entries
- Add signage with clear messaging: No Trespassing. Private Property. Violators Will Be Prosecuted.
Make sure your fencing solution complies with local ordinances and doesn’t obstruct visibility, which can create more hiding spots.
For businesses that manage vacant lots or undeveloped parcels, even temporary fencing with motion lighting can make a big difference.
Step 2: Improve Lighting and Visibility
Most encampments form under cover of darkness—literally. Areas with poor visibility or shadows become easy hiding spots.
🔦 Conduct a nighttime walkthrough of your property
🔦 Replace burnt-out bulbs and add lighting to blind spots
🔦 Use motion-sensor lights in alleys, parking areas, and behind buildings
🔦 Install lighting above signage to improve visibility and enforcement
Better lighting doesn’t just deter encampments. It also improves employee and customer safety, especially during early morning or evening hours.
Step 3: Implement Regular Patrols and Real-Time Monitoring
No deterrent is more effective than consistent presence. Even if you can’t afford full-time security officers, mobile patrols offer a budget-friendly solution with high visibility.
At Delta Protective Services, our patrol officers provide:
- Scheduled and random site visits
- Real-time reporting and photo documentation
- Trespasser removal coordination with local law enforcement
- Early detection of loitering or encampment activity
If you recently cleared an encampment, we recommend daily patrols for the first 2–3 weeks, then adjusting based on activity and risk.

Step 4: Post Legal Signage (and Document It)
Under California law, signage plays a critical role in supporting enforcement action. Posting the right signs in the right places lets law enforcement act faster and gives you legal standing in case of dispute.
- Signs must be posted at all access points
- Include legal language referencing Penal Code 602 (Trespassing)
- Date-stamp your signs and take photos for documentation
- Refresh damaged or removed signs regularly
Tip: Use both English and Spanish versions if applicable in your area.

Step 5: Partner With Local Law Enforcement and Community Programs
While property protection is your responsibility, you’re not alone. Many cities in California now offer multi-agency task forces, outreach teams, and fast-track protocols to help business owners manage encampments.
Coordinate with:
- Local police departments or community service officers
- City code enforcement and public works
- Homeless outreach groups
- Business improvement districts (BIDs)
Programs like STAART (Stockton Taking Action Against Retail Theft) offer workshops and tools for business owners, such as “How to Be a Good Witness” and community reporting portals.
If you’re located in Stockton, consider attending an upcoming session to learn how to work in partnership with the San Joaquin County DA’s Office and other local leaders.
Step 6: Don’t Forget the Follow-Up
The biggest mistake property owners make? Thinking the job is done after cleanup.
To truly transform your space, you need follow-up steps like:
- Regular site checks for trash, drug paraphernalia, or signs of return
- Ongoing maintenance of fencing and lighting
- Revisiting your patrol schedule and adjusting based on activity
- Monthly property reviews with your security provider or facilities manager
This is where having a reliable security partner makes a major difference. At Delta Protective Services, we not only provide mobile patrols but also consult on environmental design, site layout, and long-term prevention strategies.
Case Example: Before and After Security Transformation
One of our recent clients, a commercial strip mall in Central California, had persistent encampments forming behind its vacant end unit. The back alley was dark, unfenced, and lacked signage.
After an incident involving a break-in and fire, we implemented a 4-point transformation plan:
- Installed perimeter fencing with lockable gates
- Upgraded lighting along the alley and dumpster area
- Posted legal signage with 24-hour response information
- Initiated daily patrols for 30 days, then scaled to weekly checks
Since implementation, the site has had zero new encampments, and tenant complaints have dropped significantly.
Final Thought: You Can Reclaim And Protect Your Property
Dealing with encampments is frustrating. But with the right tools, you don’t have to live in constant cleanup mode. You can create a space that’s not just cleared—but protected.
Take proactive steps now:
- Secure your perimeter
- Increase visibility
- Enforce with signage
- Partner with professionals
- Maintain consistent oversight
