Security guard services in Costa Mesa for the bars and shops on Main Street and at Pacific City, hotels along Pacific Coast Highway, Huntington Harbour homes and the industrial parks off Bolsa Avenue. Officers are unarmed, licensed by the Bureau of Security and Investigative Services (BSIS), and briefed on written orders for each site.
Costa Mesa is a retail and events city with an industrial spine. South Coast Plaza and the Segerstrom arts campus sit at one end, the OC Fair & Event Center runs a month-long fair in the middle of summer, and Harbor Boulevard carries a long line of older commercial property that the city has spent years redeveloping.
The 2025 OC Fair ran from July 18 to August 17 and drew 1,162,872 visitors across the run, with eight sold-out days. For a business near Fair Drive, that is a month of overflow parking and foot traffic rather than a single busy weekend.
CAL Security Group is a BSIS-licensed Private Patrol Operator (PPO). Every officer on a post is unarmed, and we say so before quoting. Post orders are written for the address, and they say what the officer does rather than leaving it to judgement at 1 a.m.
That rule is about labour rather than security, but it lands in the same place a loss prevention conversation does. Self-checkout is where most walk-out theft happens in a supermarket, and a store now has to put a person near it either way.
High-end retail and performance venues with structured parking and evening crowds. Floor presence during trading hours, structure patrols after closing, and event-night cover when the halls are full.
Retail security →A month of fair traffic in summer, plus markets, shows and swap meets the rest of the year. Businesses along Fair Drive and Newport Boulevard buy lot officers for those dates, separate from any standing post.
Event security →Bars, restaurants and creative spaces around Harbor and 19th, and The LAB and The CAMP off Bristol. Evening door cover, patio watching and a walk back through the lot at closing.
Nightlife security →Older motels and strip commercial in the middle of a long redevelopment. The Mesa Motel site, vacant from 2022, won approval in 2025 for conversion into 47 affordable units, and empty buildings mid-conversion need someone checking them.
Vacant property →Office and light industrial buildings toward the John Wayne Airport side of the city, quiet after 6 p.m. Lobby cover by day, patrol rounds and dock checks at night.
Office security →Orange Coast College and Vanguard University each run their own campus safety departments, and the housing and retail around them keep their own hours. Patrol routes here cover parking areas and back alleys more than front doors.
Costa Mesa is about 33 miles southeast of our office at 1208 W Jefferson Blvd in Los Angeles. Other city pages close by, by straight-line distance:
Two of these decide what you pay the city, and one decides who is allowed to stand in your shop.
Costa Mesa's cannabis rules require security personnel to hold a licence from the Bureau of Security and Investigative Services. The city moved away from a blanket 24-hour guard requirement in 2024, so cover now runs through business hours, deliveries and whatever your own permit conditions add, which vary shop to shop.
Dispensary security →Under the city's alarm ordinance a service charge applies from the third police false alarm response in a 12-month period, and from the second fire false alarm. The city's own services and fees page lists a $210 false alarm fee, with the first two police responses free.
Alarm response →Costa Mesa can stop police and fire response to an address 10 days after written notice. Once that happens, responders come only where a caller verifies an actual fire, a crime in progress or an extreme emergency. There is a 10-day window to request a hearing.
Every officer holds a BSIS guard card: fingerprints through the California Department of Justice (DOJ) and the FBI, 40 hours of training and 8 hours a year afterwards. Every patrol operator carries at least $1,000,000 in general liability per occurrence, the figure fixed by Business and Professions Code Section 7583.40.
Unarmed guards in California bill at about $22 to $40 an hour on the open market, event work included. That is an industry-published range. Our price comes out of your hours and posts. Costa Mesa sets no city minimum wage, so the wage floor is California's $16.90 an hour in 2026.
Retail and cannabis posts are priced by trading hours, which is a larger weekly total than most owners expect: a shop open 10 a.m. to 9 p.m., seven days, is 77 hours a week before anyone talks about overnight cover. Fair-season posts are priced by date. Patrol routes shared between buildings bill per visit.
The quote lists each of those on its own line, so dropping a block of hours shows up as a number rather than a negotiation. Ranges by property type are in our cost guide, and event pricing in the event security cost guide.
Which hours, which doors, which departments. The pattern in your own loss data decides where the officer stands.
Let us know what you run, a Main Street bar, a PCH hotel, a Harbour HOA or an industrial site off Gothard, and which dates or hours worry you. We will walk the property and send a written quote.
