Best construction security companies in Detroit (2026)
Detroit's construction rebound has put cranes back over downtown and sent commercial work fanning out into the suburbs, which makes choosing the best construction security company in the metro a real decision rather than a formality. District Detroit and the Michigan Central revival in Corktown sit alongside automotive plant expansion and steady commercial building in Troy and Auburn Hills, and each site type carries its own theft and trespass profile. The agencies worth considering are the ones that can guard a fenced urban infill lot one week and a sprawling suburban build the next, with the licensing and insurance to back it.
Calvis is not a licensed security provider and does not employ guards. It vets construction security agencies across metro Detroit, confirms their LARA licensing and insurance, and matches your project to the ones suited to the site and the schedule. Rather than calling names off a list and checking credentials yourself, you get a shortlist of agencies that have already cleared Calvis's vetting and have a track record on jobsites like yours.

Inside construction site security in Detroit
Metro Detroit is in the middle of a layered building cycle, with downtown redevelopment around the District Detroit and the Michigan Central project in Corktown running alongside major automotive plant construction and a steady stream of suburban commercial work in Troy and Auburn Hills. Urban infill sites face vacant-lot trespass, scrapping, and copper theft, while the larger suburban and plant builds spread equipment and materials across footprints too big for a single post to watch. Michigan winters add their own pressure, leaving structures exposed during weather shutdowns and shortening the daylight hours when sites are actually staffed. The mix of dense downtown lots and wide suburban tracts means coverage plans rarely look the same from one project to the next.
Matched to
what you need.
Security needs aren't one-size-fits-all. The Detroit network spans these construction site security specialties — tell us what you need and we match you to the agencies built for it.
Overnight & Weekend Jobsite Coverage
Officers hold the site through nights and weekends, with extra attention to the long winter-weather shutdowns when Detroit structures sit exposed and crews stay home for days. Coverage tracks the build phase, tightening during the rough-in and finish stages when copper and fixtures are most at risk.
- Ideal for
- Downtown infill and suburban commercial builds that go dark overnight and through extended cold-weather stoppages.
- Coverage
- District Detroit, Corktown, Midtown, downtown Detroit
Equipment & Material Theft Prevention
Coverage centers on what gets scrapped and resold in metro Detroit — copper, tools, HVAC and appliance units, and metal stock. Officers secure the laydown and tool storage, log material pulls, and watch the access points where scrappers and thieves move stolen metal off urban and suburban sites alike.
- Ideal for
- Infill sites exposed to scrapping plus suburban projects with appliance packages and equipment stored on site.
- Coverage
- Corktown, Midtown, Hamtramck, Highland Park, Warren
Access Control for Trades & Deliveries
A posted officer checks subs, suppliers, and inspectors against the day's schedule and keeps a running access log. On tight downtown lots and active plant sites with constant deliveries, that checkpoint keeps unbadged people and stray vehicles off the structure and gives the GC a clean record of who was on site.
- Ideal for
- Constrained urban lots and large plant builds with heavy delivery traffic and rotating subcontractors.
- Coverage
- District Detroit, downtown Detroit, Dearborn, Auburn Hills
Mobile Patrol & Camera-Tower Monitoring
Marked patrol units cover several sites on randomized routes while solar camera towers watch perimeters, equipment yards, and the dark corners that no officer can stand on continuously. This pairing suits the wide automotive-plant and suburban commercial footprints where one fixed post leaves too much unwatched.
- Ideal for
- Automotive plant construction and large suburban builds, plus owners coordinating multiple smaller sites.
- Coverage
- Troy, Auburn Hills, Sterling Heights, Romulus, Dearborn
Fire Watch for Hot Work & Welding
Fire watch officers cover welding, cutting, and torch work and stay posted through the required cool-down after crews leave. They keep extinguisher access clear and maintain the written log that the GC, insurer, and local fire authority require — important on plant builds and steel-heavy structures with extensive hot work.
- Ideal for
- Automotive plant and structural-steel phases, or sites running with a temporarily impaired fire-protection system.
- Coverage
- Auburn Hills, Troy, downtown Detroit, Dearborn, Warren
A real bar,
not an ad auction.
Every agency in Detroit clears the same four checks before it can take construction site security work. Licensing is verified through the Michigan Department of Licensing and Regulatory Affairs (LARA).
State licensing verified
Every agency holds an active state security license. We confirm it before any agency can take work.
Active insurance on file
Current general-liability (and where applicable, workers' comp) coverage is verified, not assumed.
Background-checked officers
Agencies field licensed, background-checked guards — the people who actually show up on site.
Tracked reliability record
Shift-reliability is measured on the platform. Agencies that no-show or slip on coverage are removed.
What construction site security costs in Detroit
Standard posts, patrol, and monitoring. Recurring contracts are typically priced below on-demand rates.

Common
questions
Calvis screens each agency before it reaches your shortlist — confirming an active LARA security license, checking liability and workers' comp coverage, and reviewing the agency's history on actual construction sites rather than retail or patrol-only contracts. Agencies that do not clear those checks are not matched to metro Detroit projects.
In the Detroit market, unarmed construction officers typically run about $27 to $42 per hour and armed officers about $50 to $82 per hour, depending on shift length, site risk, and how quickly coverage is needed. On large suburban and plant sites, camera towers and mobile patrol are often more economical than a fixed post and are quoted separately. Calvis pulls comparable quotes so you see the actual range rather than one number.
The agencies are licensed, not Calvis. Every officer on your Detroit jobsite works for an independent agency licensed through the Michigan Department of Licensing and Regulatory Affairs (LARA). Calvis is a vetting and matching service that connects you with those licensed agencies; it does not hold a security license or employ guards itself.
Copper, metal stock, tools, and HVAC units are prime scrapping targets across metro Detroit, especially on exposed downtown infill lots. Vetted agencies counter that by securing laydown and tool storage, logging material pulls, and watching the access points where stolen metal leaves the site — backed by camera towers and mobile patrol on the wide plant and suburban footprints a single post cannot cover.
Hiring direct means trusting one agency's own pitch and verifying its LARA license and insurance on your own. Calvis has already vetted multiple construction-focused agencies across metro Detroit, so you get a shortlist of qualified options, comparable pricing, and a quicker path to coverage — valuable when a downtown lot or plant site needs guards before the next phase begins.
