A property with five entrances and twelve tenants creates five different ways for the wrong person to walk in unnoticed. Facility managers overseeing business parks and multi-tenant offices deal with this every day: lost or copied keys, no record of after-hours entry, and no way to prove who accessed a space when something goes missing. The same challenge shows up for companies running several office locations, where each site handles access differently and nobody has a full picture. Access control replaces guesswork with a system that tracks entry point by point, whether that’s one building with multiple tenants or several offices across town.
What are the four types of access control?
Commercial properties typically use one of four access control types:
- Discretionary Access Control (DAC) — property owner or manager sets permissions for each entry point
- Mandatory Access Control (MAC) — access levels are fixed by security policy, common in high-security facilities
- Role-Based Access Control (RBAC) — permissions are tied to job role, useful for multi-tenant buildings with varying staff levels
- Rule-Based Access Control — access follows set conditions, like time of day or day of week
Business parks and multi-location offices most often use RBAC or a hybrid model, since tenant and employee access needs vary by space and schedule.
Why Traditional Locks and Keys Fall Short in Multi-Tenant Buildings
The Turnover Problem
Every time a tenant moves out or an employee leaves, someone has to think about rekeying. That’s not just a hassle, it’s a cost that repeats itself every single time there’s turnover, and in a business park with a dozen suites, turnover happens more often than owners would like. A single lost or copied key doesn’t just put one suite at risk either. If several units share a master key system, one missing key can compromise every space on that system at once.
Access control sidesteps the whole problem. Instead of cutting new keys or swapping locks, a lost credential gets deactivated in seconds, and a new one gets issued just as fast. Nobody’s driving out to rekey a door at 6pm on a Friday.
No Record of Who Went Where
A key doesn’t tell you anything after the fact. If a tenant reports something missing or two people disagree about who was in a space and when, a lock and key system has no answer. There’s no log, no timestamp, nothing to point to.
This is part of why more businesses are moving away from physical keys altogether. HID Global’s 2024 State of Physical Access Control Report found that mobile credential use has climbed steadily industry-wide, with more organizations shifting identity and entry management onto phones instead of hardware. That shift isn’t happening because mobile is trendy. [1] It’s happening because a system that logs entry gives owners and facility managers something keys never could: an actual record.
Choosing the Right Credential Type
Not every tenant or every building needs the same credential. The right fit depends on how much traffic a space sees and how long tenants tend to stay.
| Credential Type | Best Fit |
| Key fob / card | High-turnover retail suites, spaces with frequent staff changes |
| Mobile credential | Offices where tenants already manage most things from a phone |
| Biometric | Single long-term tenant, high-security space, or areas with sensitive equipment |
A retail suite that turns over staff every few months benefits from fobs that get reissued fast. A single, long-term office tenant might prefer something that can’t be lost or handed off at all.

Managing Access Across Multiple Locations Without Losing Control
The turnover problem inside one building is really the same problem companies run into across several buildings, just at a bigger scale. A business running three or four office locations deals with the same lost-key risk and the same lack of a paper trail, multiplied by every site.
One Dashboard Instead of Five Systems
Owners running multiple locations often end up with a different access system at each site, installed at different times by different vendors. That means logging into separate platforms just to see who has access where. Cloud-based access control solves that by putting an entire campus, including multiple buildings, under one admin panel, so a facility manager can see every entry point across every site from a single screen instead of piecing together the picture location by location. [2] We’ve served the Northeast Ohio area since 1974, and this kind of shift away from patchwork systems is one of the biggest changes we’ve watched happen in the field.
Setting Access by Role, Not by Building
Permissions don’t have to be tied to a specific building at all. A regional manager who oversees three offices can get access to all three under one credential, while an employee who works out of a single site only gets access to that one location. Role-based permissions follow the person, not the building, which matters a lot once a company has more than one address.
Handling Vendor and Visitor Access Without Losing Oversight
Cleaning crews, delivery drivers, and maintenance contractors move between units and between locations all the time, and most of them don’t need a permanent credential. Access control lets a facility manager set up a scheduled window, say a two-hour block on Tuesday mornings for the cleaning crew, without handing out a key or a card that never gets returned. The Security Industry Association notes that role-based access control is especially common among companies that regularly work with contractors or other third parties, since permissions can be scoped narrowly and pulled the moment the job’s done. [3] Managing access for service providers this way means nobody’s tracking down a contractor’s badge six months later wondering if it’s still active.
What to Look for in a System That Can Grow With You
- Centralized management — one dashboard for every entry point, at one site or several
- Role-based permissions — access tied to the person’s job, not just the building
- Real-time logs — a record of who entered where and when
- Credential flexibility — cards, mobile, or biometric, matched to how each space is used
- Local install and service support — someone who shows up when a reader stops working

Access Control FAQs for Business Parks and Multi-Location Offices
How does access control handle tenant turnover and lost keys?
Access control handles tenant turnover and lost keys by letting us deactivate a lost credential and issue a new one in seconds, instead of rekeying locks. This matters most on shared master key systems, where one lost key can put every unit at risk.
Can access control track who enters a space and when?
Access control tracks who enters a space and when by logging every entry with a timestamp, something a lock and key can never do. That record settles disputes over who was in a space and clears up questions when something goes missing.
Can I manage access across more than one location from one system?
Yes, access control lets us manage access across more than one location from a single dashboard. Cloud-based access control puts every building and entry point under one admin panel, so nothing gets pieced together site by site. Call (440) 946-6685 to see it set up for your properties.
