Keep your project on schedule and your materials where they belong.
At National Protective Service, our BSIS-licensed construction security guards protect San Francisco jobsites from theft, trespass, and vandalism—while maintaining safe, orderly access for workers and deliveries.
From demolition to handover, we design a phase-based plan that covers gate control, perimeter patrols, after-hours protection, equipment watch, and incident reporting with photos.
Choose armed or unarmed coverage, fixed posts or mobile patrols, and optional camera/trailer monitoring. Supervisors conduct unannounced checks, and your account manager keeps communication tight with your superintendent and PM.
Our officers are fully licensed by the California Bureau of Security and Investigative Services (BSIS), trained according to industry standards set by ASIS International, and work in close coordination with the Local Police Department to ensure rapid response and community safety. Whether you require threat deterrence, emergency response, or asset protection, our team delivers professional, discreet, and reliable security solutions tailored to your needs.

Choose armed construction security when the site stores high-value equipment, copper, or tools, or when the surrounding area presents elevated risk. Our armed officers maintain a professional, non-confrontational presence while delivering visible deterrence and decisive response when required. Each officer holds current BSIS credentials and completes firearms proficiency and judgment training with strict use-of-force policies. We’ll help you decide where armed coverage is most effective—primary gate during overnight hours, roving yard patrols, or targeted weekends/holiday periods. Post orders typically include vehicle screening, lock-up and open-up procedures, alarm response, and coordination with law enforcement and your GC. The goal: protect assets and keep the job moving without friction.
Quick duties: vehicle and pedestrian access control; high-value asset watch; alarm and break-in response; law-enforcement coordination; evidence-grade reporting.
Unarmed construction guards are the backbone of daily site control. Officers verify worker badges, check vendor credentials, manage delivery queues, and maintain clean, safe entries. They conduct perimeter and floor-by-floor patrols, document unsafe conditions, and escalate hazards to site leadership. After hours, mobile patrols deter trespass and copper theft, verify fence integrity, and ensure generators, lighting, and pumps remain secure. Training emphasizes verbal de-escalation, conflict prevention, PPE awareness, and CPR/First Aid. We can also provide fire watch during hot work or impaired systems and monitor camera trailers when deployed. Expect thorough, photo-rich reports and a calm, service-oriented presence that keeps your site productive.
Quick duties: gate guard & sign-in/out; delivery verification; patrols & fence checks; tool crib/laydown watch; camera/trailer monitoring; incident reporting.
We secure construction sites across San Francisco—SOMA, Mission Bay, Dogpatch, Bayview/Hunters Point, Potrero Hill, Treasure Island, Financial District, Embarcadero, Presidio, Sunset, and Richmond—and can stage rapid coverage in nearby Bay Area cities as needed.
