In a multi-tenant LA building, your suite door is the real perimeter. Where shared lobbies, garages, and docks fail, and what a tenant can fix.
Most offices in Los Angeles are not standalone buildings. They are suites inside towers, low-rise creative conversions, and business parks where the lobby, elevators, garage, and loading dock belong to someone else. That changes what a physical security assessment has to look at, because most of the paths an unwanted person would take to reach your door are paths you do not control.
When we assess a tenant space in a multi-tenant building, the suite itself is the last thing we look at. The findings usually live in the shared layers below it.
Building lobbies in LA range from attended desks with real visitor management to a badge reader and a camera nobody watches. The common failure is assuming the lobby does a job it was never staffed to do. A receptionist who signs in delivery drivers between phone calls is not access control. A badge reader helps, but only against people who have no patience. Anyone willing to wait for a tenant to badge in can follow them through, and in a busy building nobody questions a person walking with purpose.
An assessment maps what the lobby actually stops, not what the lease brochure says it stops. That answer determines how much work your suite door has to do.
Parking structures are the most common way into LA office buildings after hours, and the least controlled. Garage gates open slowly and close slowly. Pedestrian doors from the garage into the elevator lobby are frequently propped, broken, or on a closer so weak they never latch. Once someone is in the elevator lobby, the attended front desk is behind them, not in front of them.
Walk the garage path the way an intruder would: gate timing, stairwell doors, elevator access, and whether any of it is on camera with someone who would notice. In most buildings this is where the assessment produces its longest findings list.
Every building has a service path: the dock, the freight elevator, the corridors vendors use. It exists so that deliveries and contractors can move without crossing the lobby, which also means it is a route around every control the lobby has. Vendors prop doors to move carts. Dock areas are staffed intermittently and often by the lowest-paid, least-trained people in the building's security picture.
The assessment questions are simple. Is the freight elevator locked off from tenant floors? Are vendor visits logged and escorted after hours? Who checks the dock doors at the end of the day?
Conference centers, gyms, and rooftop decks shared between tenants create a population of people who are legitimately in the building and have no relationship to you at all. A person attending another tenant's event on the amenity floor has a reason to be inside, a lanyard or wristband, and access to the same elevator bank you use. That is not an argument against shared amenities. It is an argument for treating your suite entry as the real perimeter.
You cannot rebuild the base building, and most landlords will not. The honest tradeoff in a multi-tenant assessment is that you fix the layers you own and negotiate on the rest.
Inside your suite, the controls that matter are a real entry vestibule or at least a locked door with a camera and a way for staff to see who is asking to come in, visitor pre-registration so nobody at your door improvises, and a policy that your people challenge or report unfamiliar faces on your floor. At the building level, a tenant asking specific questions, about dock door checks, garage cameras, and after-hours vendor logs, often gets further than expected, because most tenants never ask.
A physical security assessment of a Los Angeles tenant space should start on the street: approach routes, sightlines, lighting, and how the building presents after dark. Then the shared layers, lobby, garage, dock, elevators, amenity floors. Only then the suite: entry control, visitor flow, server and records rooms, and how your team actually behaves day to day. If an assessor walks straight to your suite and starts there, they are assessing the smallest part of your risk.
