Security Patrol Services in Los Angeles
Forty Los Angeles business districts already assess themselves to pay for private security patrols. Outside those districts, after-hours coverage belongs to the property owner — and LAPD’s 2025 data logged 9,811 property crimes at LA commercial premises between 10 p.m. and 6 a.m., across every one of the department’s 21 areas. Guardian’s marked-vehicle security patrol services put a licensed officer on scheduled and randomized rounds across your Los Angeles sites — lock, gate and perimeter checks, a written warning to anyone who should not be there, and a time-stamped, photographed report for every visit.

The Los Angeles Rule
In Los Angeles, a Trespass Warning Only Counts If Someone Was There to Give It — and Wrote It Down
Most trespass on a Los Angeles commercial property happens when nobody who can lawfully say “leave” is on it. The City’s trespass ordinance is written for that gap.
Section 41.24 of the Los Angeles Municipal Code makes it unlawful to enter or be present on private property not open to the general public without the consent of the owner, the owner’s agent or the person in lawful possession, where the property is posted — and subsection (f) specifies the posting: a sign reading THIS PROPERTY CLOSED TO THE PUBLIC / No Entry Without Permission / L.A.M.C. SEC. 41.24, in two-inch letters, at every walkway and driveway and at least every fifty feet along an unenclosed lot. The ordinance’s “private property” includes yards, driveways, parking areas and vacant lots, not just buildings.
Subsection (b) is the part a patrol buyer should read twice. A person who has been advised to leave and not return — by the owner, the owner’s agent, the person in lawful possession, or a peace officer at their request — and who comes back within six months is subject to arrest. The advisement must be documented in writing by the person who made it, with the name of the person advised, the date, the approximate time, the address and the type of property, and that record must be kept for at least a year. And under subsection (g), a single written request that names its dates can cover a peace officer’s assistance for up to twelve months.
An absent owner cannot make that advisement, and a camera cannot either. A patrol officer on the property can — the role a Los Angeles owner engages a patrol company to fill — and a time-stamped patrol report is how it gets written down. Guardian’s security patrol services in Los Angeles run scheduled and randomized rounds under CA PPO #121089, and every visit is logged with a time-stamped report and photographs, so a warning given at 2 a.m. exists on paper the next morning. Where a site needs a fixed presence, Guardian adds a security guard post; where it needs eyes between rounds, live video monitoring fills the gap.
“This advisement must be made by the owner, the owner’s agent, the person in lawful possession or a
peace officer at the request of the owner, owner’s agent or person in lawful possession. The advisement
shall be documented in writing by the individual making it and shall include the name of the person advised,
the date, approximate time, address and type of property involved. Such documentation shall be retained for
a minimum period of one year.”
— Los Angeles Municipal Code § 41.24(b), Trespass on Private Property
Posted Means Enforceable
LAMC § 41.24(a) and (f): entry onto posted private property without consent is unlawful; the sign must read "THIS PROPERTY CLOSED TO THE PUBLIC / No Entry Without Permission / L.A.M.C. SEC. 41.24" in two-inch letters, at every walkway and driveway and at least every fifty feet along an unenclosed lot.
Six Months After a Warning
LAMC § 41.24(b): a person advised to leave and not return who comes back within six months is subject to arrest — if the advisement was documented in writing and the record kept at least a year. Violation is a misdemeanor or an infraction (§ 41.24(i)).
Twenty-Four Hours for an Open Business
LAMC § 41.24(d): on property open to the public the same advisement runs for 24 hours, and a request to leave must be rationally related to the services or facilities provided.
One Letter, Twelve Months
LAMC § 41.24(g): peace-officer assistance normally takes a separate request each time — but a single written request that states its dates can cover a period of up to twelve months.

The Basics
What Security Patrol Services Cover in Los Angeles
Security patrol services put a licensed officer in a marked Guardian vehicle on a route through your properties — scheduled visits, randomized so no one can time them, with the same checks at every stop — locks, gates, fence lines, lighting, and the vehicles and people that should not be there. California calls the officer a street patrolperson: a security guard who serves multiple customers by motor patrol. Every visit is logged with a time-stamped report and photographs, and a suspicious finding follows a documented escalation — warn, alert local law enforcement with a real-time description when a crime is under way, and report.
A patrol is the right tool when a posted officer is more presence than one site needs and less coverage than the portfolio needs. A staffed 24/7 guard post typically runs $25–30 per hour at one address; a patrol route covers many, and many operators run both — the guard in the lobby during business hours, the patrol across the lots, yards and satellite sites after hours, with live video monitoring watching between rounds. Contact us for a quote on your specific route.
Our Operations Center
Los Angeles Patrol Routes Run From Our California Operations Center
A patrol vehicle is only as good as what happens between the officer and the office. Every Guardian patrol route in Los Angeles is run from our California operations center: the route is built there, every visit is logged there with a time stamp and photographs, and every report reaches the property owner from there. When an officer finds an open gate at a Sun Valley yard or a stranger in a Koreatown parking structure at 1 a.m., the operations center is another set of eyes — checking what the site’s own cameras show where it has them, alerting LAPD with a real-time description if a crime is under way, and sending another Guardian unit when a site needs more than one officer.
That record matters more in Los Angeles than in most places. Section 41.24 turns a trespass warning into arrest exposure only if the warning is documented in writing — name, date, approximate time, address, type of property — and kept for a year. LAPD’s 2025 data puts the single busiest after-hours hour at LA commercial premises at midnight. A patrol service that writes down every warning it gives at 12:30 a.m., and can produce it months later, is doing the part of the job the ordinance actually depends on.

Property Types
Built for the Portfolios, Corridors and Satellite Sites Los Angeles Businesses Actually Run
Los Angeles is a patrol city because its commercial property is spread out: strip centers strung along Ventura, Van Nuys and Sepulveda boulevards, industrial lots in Sun Valley, Pacoima and the Harbor Gateway, office parks in Warner Center and Playa Vista, the dealership rows of Van Nuys Boulevard and South Figueroa, self-storage yards along the Valley’s boulevards, and the surface parking around all of it.
Forty of the city’s commercial districts — Downtown, Hollywood, the Westside, the Harbor and the San Fernando Valley — have organized as business improvement districts whose assessments buy district-wide services, private security patrols among them. That still leaves the property itself: the lot behind the storefront, the loading dock, the rear alley and the after-hours gate are the owner’s to cover, inside a district or outside one.
Guardian runs patrol routes across Los Angeles County — from downtown and the San Fernando Valley to the Westside, the South Bay and the Harbor, and the Eastside and San Gabriel Valley — built for the owner with six addresses and no guard budget for any of them.
Portfolios & Corridors
How One Patrol Route Covers an LA Portfolio Without a Guard at Every Address
Los Angeles has 40 operating business improvement districts. The City Clerk’s own guide lists private security patrols first among the services they provide, notes that by law they exist for commercial areas only, and explains that every property or business owner in the district pays the assessment that funds them. They are the model in miniature: a district that cannot post a guard at every storefront buys a patrol for the whole corridor instead.
Most Los Angeles commercial property sits outside a district, and a district’s assessment buys services for the district as a whole — the owner’s own lot, dock and alley are still the owner’s. Guardian builds the same coverage for a private portfolio: one marked route across a landlord’s strip centers, a franchisee’s six locations, or an operator’s yards in the Valley and the Harbor, with visit windows set to each site’s hours and a photographed report per stop. Add a fixed guard post at the one address that needs a person at the door, and live video monitoring at the site that needs eyes between rounds.

Los Angeles Data
9,811 Property Crimes Hit LA Commercial Premises Between 10 p.m. and 6 a.m. in 2025 — in Every One of LAPD's 21 Areas
LAPD’s 2025 incident data records 39,347 property-crime offenses at 54 commercial premise types in the City of Los Angeles — stores, restaurants and bars, offices, hotels, parking lots and garages, dealerships, business yards, storage facilities, warehouses and construction sites. 9,811 of them, 24.9%, were logged between 10 p.m. and 6 a.m. The single busiest after-hours hour was midnight, and Saturday was the busiest night.
Those 9,811 offenses were spread across all 21 LAPD areas. Central logged the most (1,147), then Pacific (782), North Hollywood (711), Topanga (636), Hollywood (628) and Olympic (561) — downtown, the Westside and the Valley all in the top six. Parking lots and garages were the most common premise (2,847), then LAPD’s catch-all “Other Business” category (1,718), restaurants (777) and bars (687). Vandalism (2,847) and burglary (2,196) led the offense mix. When we ran the query, 724 of the after-hours offenses — 7.4% — had been cleared by arrest, and seven in ten still carried the status “Investigation Continued”.
Read those numbers the way a property manager with sites in three council districts would. The after-hours exposure is not on one block; it is everywhere the portfolio is, at the hour when no one is on site, and it is rarely solved afterward. That is the case for a marked vehicle on a route — a visible, documented presence at each site in the hours the data points to — rather than a posted officer at one address.

FAQ
Security Patrol Services in Los Angeles — FAQ
What does Los Angeles's trespass ordinance require before a patrol warning can lead to an arrest?
Three things: posted property, a warning from someone entitled to give it, and a written record. Under Los Angeles Municipal Code § 41.24, entering posted private property that is not open to the public without consent is unlawful, and subsection (f) sets the posting — a sign reading “THIS PROPERTY CLOSED TO THE PUBLIC / No Entry Without Permission / L.A.M.C. SEC. 41.24” in two-inch letters at every walkway and driveway and at least every fifty feet along an unenclosed lot. Under subsection (b), a person advised to leave and not return — by the owner, the owner’s agent, the person in lawful possession, or a peace officer at their request — who comes back within six months is subject to arrest, but only if the advisement was documented in writing with the person’s name, the date, the approximate time, the address and the type of property, and that record is kept for at least a year. For an open business the same mechanism runs for 24 hours (subsection (d)), and a single written request that states its dates can cover peace-officer assistance for up to twelve months (subsection (g)). A Guardian patrol officer on the property is the person there to give the warning, and the time-stamped patrol report is where it gets written down.
How much after-hours property crime hits Los Angeles commercial premises, and where?
Nearly ten thousand offenses, and everywhere. LAPD’s 2025 incident data records 39,347 property-crime offenses at 54 commercial premise types in the City of Los Angeles, and 9,811 of them — 24.9% — were logged between 10 p.m. and 6 a.m. They fell across all 21 LAPD areas: Central logged the most (1,147), then Pacific (782), North Hollywood (711), Topanga (636), Hollywood (628) and Olympic (561). Parking lots and garages were the most common premise (2,847), vandalism (2,847) and burglary (2,196) the most common offenses, midnight the busiest hour and Saturday the busiest night. When we ran the query, 7.4% had been cleared by arrest. Burglary inside commercial buildings has its own pattern — see our Los Angeles commercial burglary statistics — but the after-hours picture across every kind of commercial premise is the same in the Valley, on the Westside and downtown: the exposure is spread out, it peaks when no one is on site, and it is rarely solved afterward. That is what a patrol route is built for.
Do Los Angeles business districts already pay for private security patrols?
Many do. Los Angeles has 40 operating business improvement districts, and the City Clerk’s own “BIDs 101” guide lists private security patrols first among the services they provide, alongside sidewalk cleaning and maintenance. A BID is a geographically defined commercial area — by law, commercial areas only — in which services are paid for through a special assessment charged to every member, collected on the property-tax bill or billed by the City Clerk, which holds a contract with every district and monitors it. They exist in the major commercial areas of Downtown, Hollywood, the Westside, the Harbor and the San Fernando Valley. If your property sits inside one, the district’s assessment buys services for the district as a whole; your own lot, loading dock and after-hours gate are still yours to cover. If it sits outside one — most Los Angeles commercial property does — the patrol is yours to arrange. Guardian builds private routes on the same principle: one marked vehicle covering many addresses.
Can one Guardian patrol route cover a Valley strip-center portfolio, a Westside office park and a Harbor-area yard?
Yes — that is the shape most Los Angeles patrol routes take. A route is built around the sites, not the map: each address gets its own visit windows set to its hours and its exposure — the strip center after the last tenant closes, the office park’s garage and loading area overnight, the Harbor yard’s gate and fence line through the small hours — and the officer works the same checks at every stop: locks, gates, fence lines, windows, lighting, and the vehicles and people that should not be there. Visits are scheduled and randomized so no one can time them, every stop produces a time-stamped, photographed report, and any warning the officer gives is written down. Where one address needs a person at the door during business hours, Guardian adds a fixed security guard post; where a site needs eyes between rounds, live video monitoring covers the gap. Contact us with the addresses and we will scope the route.
