The Challenge
Since June 2025, Ten Pounds of Scrap Copper Without a License Is a Crime in Fresno
What empties a Fresno construction budget is seldom one spectacular loss. It is the wire pulled back out of a finished rough-in, the copper reel that vanished from the staging area over a weekend, the job box pried open for the drills inside — each replaced at today’s price, on nobody’s schedule, with trades resequenced around the gap.
Copper is the loss pattern Fresno has legislated against twice. California Penal Code § 487j makes taking copper wire, cable, tubing or piping worth more than $950 grand theft. And in June 2025 the City added its own layer: Fresno Municipal Code Chapter 9, Article 36 makes it unlawful to possess or transport ten pounds or more of scrap commercial-grade copper or aluminum wire, cable or power components without a license, bans stripping the sheathing off commercial-grade wire outright, and sets the administrative penalty at $1,000 for every 20 feet of wire — with licensed contractors and their crews expressly exempt. State law adds the recycler chokepoint: under Business and Professions Code § 21608.5, a scrap dealer cannot pay for nonferrous metal until the third business day after the sale, and must photograph the seller and keep a copy of their photo ID.
Each of those laws reaches the thief only after your material is already scrap — and conventional coverage has the same timing problem. A gate guard sees the gate; a drive-by patrol sees the site for a few minutes an hour; a recording camera testifies the next morning. Live video monitoring is built for the minutes in between: a trained agent watching the whole perimeter as it happens, who challenges the person over the site speakers while they are still at the fence and, if the warning does not move them, alerts and coordinates with law enforcement using a live, verified description. On a pad with no power run yet, the same coverage arrives on a solar-powered rapid-deploy surveillance trailer.
Construction site theft costs the U.S. construction industry about $1 billion a year, and under 7 percent of
stolen tools, materials and equipment is ever recovered.

What We Watch
What Construction Site Monitoring Covers in Fresno
Guardian’s construction site monitoring puts trained human agents on your job-site camera feeds in real time — gates, fence line, material staging and equipment lay-downs — watching for theft, break-ins and trespass instead of leaving footage for someone to review later.
AI flags activity on camera in under a second. A live agent then verifies what triggered it, and if it is a real intrusion, speaks directly to the person through on-site speakers before they reach equipment or materials. The same agent alerts and coordinates with law enforcement and sends you a documented incident report.
The economics are why most contractors switch: on-site guards run $25–30 per hour, while live video monitoring runs under $3 per hour — roughly 70% less for continuous coverage of the whole site rather than one gate.
Our Operations Center
Monitored Live for Fresno Job Sites From Our California Operations Center
Guardian’s California operations center staffs real people on Fresno feeds around the clock — eyes on the trench, the lay-down and the gate as it happens, not a hard drive opened after the loss. When AI flags movement, in under a second, an agent opens the camera, sorts a late-working crew member or a stray headlight from an intruder, and speaks to the intruder directly over the site speakers before anything leaves the lay-down.
Fresno’s alarm code puts the cost of a crying-wolf system on its owner. Under Fresno Municipal Code section 10-811, a subscriber reimburses the City for the police response to each false alarm, at the rate set in the Master Fee Resolution; a system that false-alarms must be registered with the City within ten days, and an activated alarm must be silenced within thirty minutes. In February 2026 the City repealed section 10-812, the section that had placed conditions on police response to alarm systems — but an unwatched camera still produces false alarms and next-day footage. When a Guardian agent has seen the intrusion live, what the Fresno Police Department receives is not an unverified signal: it is a description of the person and the exact spot on the site. And when someone needs to stand on the gravel, Guardian sends its own licensed patrol.

Built for the High-Speed Rail Corridor, Downtown Infill and the Highway 99 Yards Fresno Is Building Now
California’s high-speed rail line runs straight through Fresno, and the construction does too. In March 2026 the High-Speed Rail Authority completed the Ventura Street underpass — a grade separation more than 1,000 feet long and 90 feet wide that carries traffic under the Union Pacific and future high-speed rail tracks between F and H streets, less than a mile from the future Fresno Station site, and the 59th structure completed in the Central Valley. The same month the Authority posted the Notice of Proposed Award for the Fresno Station Early Works contract, an estimated $50 million, two-year package that retrofits and restores the historic Fresno Depot and builds out utilities, demolition, ADA improvements and plaza space at the station’s H and G Street entrances downtown.
Around the corridor, the rest of the city builds in its own patterns: infill and rehabilitation work through downtown, the Fulton corridor and Chinatown beside the station site; tilt-up, warehouse and yard work along the Highway 99 and Golden State Boulevard corridors in south Fresno; equipment and materials yards off East Central Avenue; and roadway and subdivision work on the city’s growing northwest edge around Veterans Boulevard.
All of it shares the same exposure once the crews leave: staged material, parked equipment, an unwatched gate. Guardian covers the whole spread — fixed cameras and speakers on a multi-year build, and solar-powered surveillance trailers on a pad with no service yet, a lay-down that moves with each phase, or a linear corridor segment that needs coverage this week. Guardian monitors construction and industrial property across Fresno and Fresno County, including Clovis, Sanger, Selma and Kingsburg.
Job Sites
How Remote Video Monitoring Protects a Fresno Job Site After the 10 p.m. Stop
Under Fresno’s noise ordinance, construction, repair and site-preparation work done under a construction permit — the City’s or another agency’s — is exempt only between 7 a.m. and 10 p.m., on any day except Sunday. For the other nine hours of every night, and all day Sunday, the site is required to be quiet — and nobody is on it, while the cable, the conduit and the tools stay wherever the crew left them. Guardian builds the coverage plan for exactly those hours: cameras and two-way speakers on the perimeter and the staging areas, hard-mounted on a long build, or carried on a solar-powered trailer that relocates as the phases turn over.
After the stop, a person inside the fence gets flagged by AI, verified by a live agent, and challenged through the speakers before the material moves. If they press on, the agent alerts and coordinates with law enforcement with a description of the person and any vehicle — and the incident closes with a time-stamped report in the owner’s or the general contractor’s inbox.

Fresno Data
Fresno Reported 1,191 Non-Residential Burglaries in 2025 — 777 of Them at Night
The California Department of Justice’s Crimes and Clearances file records what every California agency reports each year, split between residential and non-residential burglary. For the Fresno Police Department’s jurisdiction, 2025 closed with 1,926 burglaries, and 1,191 of them — 61.8 percent — were non-residential: businesses, commercial buildings and other premises that are not homes (CA DOJ). Of those non-residential burglaries, 777 were logged at night and 414 in the daytime — 65.2 percent after dark. In 2024 the same filter shows 1,304 non-residential burglaries. Across all 1,926 burglaries of 2025, 257 were cleared.
The state file has no premise code below “non-residential,” so it cannot isolate construction sites — and this page does not pretend it can. What it shows is the shape of Fresno’s commercial burglary problem: nearly two-thirds of it happens at night, which is exactly when a site office, a locked container or a materials warehouse sits unoccupied. Fresno has also given business owners a tool for the fence line itself: under Municipal Code section 10-2501, added in October 2024, a person who stays on business premises after being told to leave — orally or by a posted notice — or comes back after being told to keep off, commits a misdemeanor. A live agent’s spoken warning through the site speakers, time-stamped in Guardian’s incident report, documents that the person was told.

FAQ
Construction Site Security in Fresno — FAQ
How many non-residential burglaries does Fresno record, and when do they happen?
1,191 in 2025, and 777 of them — 65.2 percent — were logged at night, according to the California Department of Justice’s Crimes and Clearances data for the Fresno Police Department’s jurisdiction. In 2024 the same file shows 1,304. The state’s data does not isolate construction sites, but the pattern it does show — nearly two-thirds of commercial break-ins after dark — is the after-hours window when a job site’s office, containers and lay-down sit unoccupied. That is the window Guardian staffs for Fresno contractors: a live agent on the cameras overnight, a spoken warning before the loss, and — when a crime does happen — a verified account handed to Fresno PD instead of a next-morning inventory.
Does Fresno have its own copper-theft law on top of California's grand-theft statute?
Yes — since June 2025. Fresno Municipal Code Chapter 9, Article 36 (“Commercial Scrap Metal,” Ordinance 2025-010) makes it unlawful to possess or transport ten pounds or more of scrap commercial-grade copper or aluminum wire, cable or power components without a license, and bans stripping the sheathing off commercial-grade wire; violations are misdemeanors carrying up to a year in jail and a $1,000 fine plus the cost of repairing what was pillaged, and administrative citations run $1,000 per 20 feet of wire. Licensed contractors and their crews are expressly exempt — the ordinance is aimed at the person leaving your site with the rough-in. It sits on top of Penal Code § 487j, which makes copper theft over $950 grand theft statewide. Both laws bite only after the wire is gone; a live agent who catches someone at the trench, and gets Fresno PD a description while they are still inside the fence, is what makes those laws matter before the loss instead of after it.
What hours can a Fresno job site legally run, and who is watching it outside them?
7 a.m. to 10 p.m., on any day except Sunday. Fresno Municipal Code section 10-109 exempts construction, repair, remodeling and site-preparation work done under a City or other agency permit from the noise regulations only inside that window; outside it, and on Sundays, only emergency work is exempt. That leaves nine hours every night — and every Sunday — when the site is quiet and its cable, conduit and tools are unattended. Guardian covers them live — an AI flag in under a second, human verification on camera, a spoken warning through the site speakers, and a coordinated alert to law enforcement with a verified description if the person does not leave.
What is high-speed rail building in downtown Fresno, and how does Guardian cover a linear or multi-phase site?
The corridor and the station. In March 2026 the California High-Speed Rail Authority completed the Ventura Street underpass — a grade separation more than 1,000 feet long that carries traffic under the Union Pacific and future high-speed rail tracks less than a mile from the future Fresno Station site, the 59th structure completed in the Central Valley — and posted the Notice of Proposed Award for the Fresno Station Early Works contract, an estimated $50 million, two-year package covering the historic Fresno Depot’s restoration, utilities, demolition and plaza work at the station’s H and G Street entrances. A corridor or multi-phase site like that has several work fronts, lay-downs that move, and fence lines measured in blocks. Guardian treats each work front as its own scope: fixed cameras and speakers where the build stands still, solar-powered surveillance trailers where it moves, every feed watched from the same operations center and every event logged in a single incident record for the owner or the general contractor.
