Who Actually Has Access to Your Building Right Now?

Ask most property managers who has access to their building and they will tell you: current tenants, the cleaning crew, and a few vendors. Ask their access control system the same question and the list is almost always longer.

The employee who left six months ago. The contractor who finished a job in February and never returned the fob. The former tenant whose key was never collected at move-out. The vendor who was given access for a one-week project and is technically still active in the system.

None of this is dramatic. It is just how buildings drift when access management is manual and nobody is responsible for keeping the list current.

Why the list grows without anyone noticing

Adding access is fast and easy. Removing it requires someone to remember to do it, have the time to do it, and know how to do it in whatever system you are using. That asymmetry is where the problem lives.

In buildings with older key card or fob systems, there is often no central dashboard that shows every active credential at once. Deactivating a card requires physical reprogramming of the panel or a service call. So it does not happen consistently -- and over time the gap between who is in the system and who should be in the system quietly widens.

What a real access audit looks like

Pull a full credential report from your access control system. Every active card, fob, PIN, or mobile credential that can currently open a door in your building. Most modern systems can export this as a spreadsheet.

Then compare it against your current tenant list, employee roster, and approved vendor list. Anything that does not match gets flagged. Anyone who left without returning a credential gets revoked. Vendors whose project ended get revoked. Shared credentials -- one fob used by multiple people -- get investigated.

This is not a complicated process. It is just time -- usually a few hours for a mid-sized building. And it almost always turns up credentials that should have been removed months ago.

Shared fobs: the risk that feels small but is not

Shared fobs are common in buildings where tenants or staff share a common area or storage space. One fob, multiple users. The problem: when you need to revoke access for one person, you have to replace the credential entirely -- which means reissuing it to everyone else who uses it.

Because that is inconvenient, it does not happen. The credential stays active. The person who should no longer have access still does, because removing them would disrupt everyone else on the same fob.

Mobile credentials solve this cleanly. Each person gets their own credential tied to their phone. Revoke one user and no one else is affected. You can also see exactly who used a door and when -- which a shared fob can never tell you.

Making access management something you can actually keep up with

The buildings that stay on top of access are the ones where it is easy to act. Cloud-managed systems -- Brivo, Verkada, Openpath -- let you add or revoke a credential in under a minute from a browser or an app. No technician. No panel programming. No service call.

When removing a credential is that fast, it actually gets done. An employee gives notice on a Friday and their access is gone before they leave the building. A vendor finishes a job and their credential is revoked the same day. That is what a controlled building looks like -- not because of discipline, but because the system makes the right thing easy.
