Questions about construction site security pricing

How much does construction site security cost in the US?

The reference price runs from $8,000 to $12,800 USD per guard post/month, pre-tax. Priced like standard guard posts, typically weighted to nights/weekends when theft risk peaks. Many sites combine a night post with mobile patrol or camera monitoring to cut cost.

What factors change the price of construction site security?

The city (prevailing wages and cost of living), the schedule and coverage required, armed vs unarmed staffing, officer profile and experience, and the risk level of the site. That's why it pays to compare several quotes.

Why should I distrust a very cheap quote?

The loaded labor cost of a single 12-hour post is roughly $7,900 per month (a $16/hr market wage + payroll taxes, workers' comp, insurance, uniforms and supervision). A rate far below that usually means staff without insurance or benefits, or an unlicensed operator — a legal risk for the client.

Do the prices include tax?

These are pre-tax reference prices. Whether sales tax applies to security services depends on the state; each company's formal quote will itemize any applicable taxes.
