Rooted in Altadena
We know Altadena block by block
Altadena climbs into the San Gabriel foothills above Pasadena, and Americal Patrol officers know this unincorporated ground, from the storefronts along Lake Avenue downtown to the revitalized stretch of Lincoln Avenue. Our security guard services in Altadena cover the hillside homes off Mount Curve Avenue, the historic blocks of Mariposa Street, and the rebuilding neighborhoods near Altadena Drive. We time our rounds to the rhythms that shape this town, the early commuter pull down toward the 210 and the quiet overnight hours on Santa Rosa Avenue, where wildfire recovery is still underway.

Local Coverage
Altadena Landmarks & Districts We Patrol Around
Familiar local knowledge is what separates a Los Angeles County security company from a national one. Our supervisors and patrol officers know these locations by name.
Eaton Canyon Natural Area
County natural area at the east edge of Altadena off North Altadena Drive, near the Pasadena line. Americal Patrol runs vacant-property checks, overnight rounds, and access-point coverage for the homes and rebuilding lots along Altadena Drive and the residential streets that climb toward the canyon. We focus on the quiet foothill blocks where construction materials and unoccupied parcels need eyes after dark.
Lake Avenue Commercial District
Altadena's main commercial thoroughfare, the historic business corridor running north from the Pasadena border up toward the foothills. Americal Patrol provides storefront checks, parking coverage, and after-hours rounds for the restaurants, shops, and offices along Lake Avenue and its side streets. We coordinate patrol timing around the dinner close and the early-morning open so the corridor is watched through its slow hours.
Loma Alta Park
County park on North Lincoln Avenue in west Altadena. Americal Patrol covers the residential blocks, apartment properties, and small businesses surrounding Loma Alta Park along the Lincoln Avenue corridor. Our officers time rounds to the after-dark window when the surrounding streets quiet down and parked vehicles and yards need a steady presence.
Farnsworth Park
Historic foothill park off East Mount Curve Avenue, a short block east of Lake Avenue. Americal Patrol serves the hillside homes and HOA-managed properties on the streets surrounding Farnsworth Park, where steep lots and mountain-edge access points reward consistent overnight checks. We build routes that hit the cul-de-sacs and shared driveways these neighborhoods depend on.
Christmas Tree Lane
The historic deodar-lined stretch of Santa Rosa Avenue, a California Historical Landmark and a holiday-season draw. Americal Patrol provides residential coverage for the homes along Santa Rosa Avenue and the adjacent streets, with extra attention during the December crowds when foot and vehicle traffic spike. The rest of the year we keep standard overnight rounds on these quiet blocks.
Cobb Estate
Former estate, now a public garden and trailhead at the top of Lake Avenue where the street meets the national forest. Americal Patrol covers the foothill residences and gated properties on the upper Lake Avenue blocks below the estate, an area of large lots and limited through-traffic. We time rounds to the late-night and pre-dawn hours when these remote streets see the least activity.
Common Questions
Frequently Asked Questions
Quick answers to the questions Altadena property owners ask us most.
How much does a security guard cost in Altadena?
Americal Patrol prices each Altadena job to the coverage it needs, the hours, the property size, and whether you add a marked patrol vehicle, with no setup fees. Whether you need overnight coverage for a hillside home off Mount Curve Avenue or storefront checks along Lake Avenue, the pricing stays flat and transparent once we scope it. Call (805) 515-3834 for a quote on residential security in Altadena.
Which parts of Altadena do you patrol?
We cover Altadena end to end, from West Altadena and the Lincoln Avenue corridor to East Altadena and the foothill blocks near Altadena Drive. Our officers run rounds through Janes Village, La Vina, The Meadows, Loma Alta, and the historic homes along Mariposa Street, with marked patrol vehicle coverage available across the unincorporated community.
Do you provide HOA and residential security in Altadena?
Yes. HOA security in Altadena is a core part of what we do, from gated communities like La Vina to the hillside cul-de-sacs and shared driveways of the foothill tracts. We set up scheduled vehicle patrols, vacant-property checks for rebuilding lots, and visible overnight rounds tailored to your association's streets. Call (805) 515-3834 to build a residential security plan.
Do you offer armed guards in Altadena?
We staff most Altadena posts with licensed unarmed officers, which fits the great majority of residential, HOA, and commercial sites in the Foothills area. When a property's risk profile calls for it, we can discuss armed coverage during your consultation. Either way, every Americal Patrol officer works under California PPO-9557 and is trained for foothill-community patrol.
