How to Start a Security Guard Business in Colorado

Market Opportunity in Colorado

Colorado's security guard market is driven by rapid population growth along the Front Range, a booming construction sector, and increasing demand from residential communities, commercial real estate, and event venues. The state added over 500,000 residents between 2010 and 2023, with the Denver-Aurora-Lakewood metro area now exceeding 3 million people. This growth has created a sustained need for unarmed and armed security services in construction site security, HOA patrol, retail loss prevention, and event staffing.

Colorado's legal cannabis industry also generates unique security requirements — dispensaries and grow facilities are required by state law to have licensed security on-site during operating hours. Additionally, the state's outdoor event culture (concerts, festivals, farmers markets) and wildfire-prone regions create seasonal demand spikes.

However, the market is not without challenges. Denver has moderate saturation from established players like Allied Universal and GardaWorld, but smaller cities and suburban corridors remain underserved. Your opportunity lies in targeting mid-sized commercial accounts, construction sites in growing suburbs (Castle Rock, Parker, Firestone), and residential HOA patrols — segments where large national firms often lack local responsiveness.
