Multi-tenant buildings run on a rotating cast of tenants, vendors, and visitors, and a lockbox with a shared key doesn't scale past a handful of units. This guide ranks the access control systems for multi-tenant buildings that property managers and building owners in New Jersey and beyond are actually installing in 2026, with a verdict on each.
- ButterflyMX wins for apartment and mixed-use lobbies with video intercom built in -- Buy.
- Brivo stays the safe default for offices and retail strips needing simple cloud management -- Buy.
- Genetec Synergis fits large enterprise portfolios but is overbuilt for a 20-unit building -- Hold.
- Salto's wireless locks cut cabling costs on retrofits where running wire to every door isn't practical -- Consider.
- Skip standalone keypad locks with no cloud audit trail for any building with more than one tenant.
Why this matters
A single-tenant office can get away with a metal key and a sign-in sheet. A multi-tenant building can't, because tenant turnover means keys walk out the door every time a lease ends and nobody re-keys 40 units on a Tuesday.
Access control systems for multi-tenant buildings solve three problems at once: they revoke a departing tenant's credential in seconds, they log who entered which door and when, and they let a property manager open a delivery door from a phone instead of driving to the site. In 2026, cloud-based platforms have mostly replaced the on-premise controller-and-badge-reader setups that dominated a decade ago, mainly because remote credential management matters more when one manager oversees several buildings.
How we ranked these access control systems
This list weighs five factors that matter specifically for multi-tenant properties: cloud management (can a manager revoke access remotely without an on-site server), credential flexibility (fob, mobile, PIN, or all three), integration with video and intercom, per-door hardware cost versus wiring requirements, and how the platform handles common-area doors shared across tenants. Systems built primarily for single-tenant corporate offices score lower here even when they're strong products, because the multi-tenant use case has different priorities.
The ranked list
1. ButterflyMX -- built for shared lobbies
ButterflyMX pairs a video intercom panel with mobile-app door release, which is why it shows up in more apartment and mixed-use lobby retrofits than any other platform on this list. Visitors call a unit from the panel, the tenant answers on their phone from anywhere, and the door opens without a fob ever changing hands. For a multi-tenant building with a single shared front entrance and dozens of individual units behind it, this is the closest thing to a category standard in 2026. Verdict: Buy for buildings where the main pain point is lobby and delivery access.
2. Brivo -- the safe default
Brivo has been a cloud access control vendor since before "cloud access control" was a common phrase, and that maturity shows in how straightforward the admin panel is for a non-technical property manager. It handles mobile credentials, fobs, and PINs, and it logs every door event with a timestamp. It's not the flashiest platform on this list, but it's the one an office manager can run without a dedicated IT person. Verdict: Buy for office and retail multi-tenant buildings that want simplicity over bells and whistles.
3. Genetec Synergis -- the enterprise-grade system
Genetec Synergis is built for portfolios, not single buildings, and it shows in the licensing model and the depth of the video-integration options. It ties directly into Genetec's Security Center video management platform, which matters if a building already runs Genetec cameras. For a 15-unit strip mall, it's more system than the job needs. Verdict: Hold unless the building is part of a multi-property portfolio already standardized on Genetec.
4. Avigilon Alta (formerly Openpath) -- the mobile-first credential
Openpath rebranded to Avigilon Alta after Motorola Solutions folded it into the Avigilon brand in 2022, and the mobile-unlock feature -- wave a phone near the reader, no app tap required -- is still the fastest credential method on this list. It's a strong fit for buildings with a younger tenant base that expects phone-based everything. Hardware cost per door runs higher than Brivo's comparable readers. Verdict: Buy for Class A multi-tenant office buildings where tenant experience is the selling point.
5. Salto Systems -- the wireless lock specialist
Salto's wireless electronic locks skip the door-by-door wiring that trips up a lot of retrofit projects, since each lock communicates over Wi-Fi or a low-power mesh instead of a home-run cable back to a controller. That makes it a fit for older multi-tenant buildings where running new cable through finished walls is expensive. Battery management becomes the trade-off -- someone has to track lock battery levels across dozens of doors. Verdict: Consider for retrofits in buildings built before the wiring existed for wired access control.
6. Honeywell Pro-Watch -- the legacy integrator's choice
Honeywell Pro-Watch has been installed by commercial integrators for years and remains common in buildings that already have Honeywell fire and security infrastructure. It's a proven on-premise-capable platform, but the interface and setup process feel dated next to the cloud-native competitors above. Verdict: Hold for buildings replacing an aging Honeywell system rather than starting fresh.
7. Standalone keypad locks -- no cloud, no audit trail
A standalone electronic keypad with a shared PIN is cheaper up front than any platform above, and it's still common in smaller multi-tenant buildings trying to save money. The problem is that a shared PIN behaves exactly like a shared key once a tenant moves out and doesn't forget the code. There's no remote revocation and no log of who used the code and when. Verdict: Skip for any building with more than one tenant on a shared entrance.
“A shared PIN on a multi-tenant front door is a shared key with extra steps -- it still has to be changed every time someone leaves.”

A system on this table only performs as well as the door hardware and wiring behind it. Cameras that watch the same entrances matter just as much as the reader on the door -- the security camera buying guide covers how to match camera coverage to the same entry points an access control system protects.
Where to buy and install
- Get a door count and wiring assessment before quoting hardware. A per-door price quoted over the phone without a site walk is a guess, not an estimate.
- Confirm the platform talks to your existing network and cameras. A cloud access control system that can't share a network switch with your camera system creates two separate maintenance headaches instead of one.
- Work with a licensed low-voltage integrator for shared common areas. DBSI installs and supports business phone systems, network cabling, and commercial security cameras for small and mid-sized New Jersey buildings, and access control on shared entrances is the kind of job that needs a technician who understands the building's existing wiring, not a self-install kit.

FAQ
What's the best access control system for a multi-tenant building?
ButterflyMX is the strongest fit for apartment and mixed-use buildings with a shared lobby entrance, since it pairs video intercom with mobile door release. Brivo is the better pick for office and retail multi-tenant buildings that want simple cloud management without video intercom.
Is cloud-based access control better than on-premise for multi-tenant buildings?
Cloud-based access control is generally the better fit for multi-tenant buildings because a property manager can revoke a departing tenant's credential remotely without visiting the site. On-premise systems like older Honeywell Pro-Watch installs still work but require someone physically at the server to make changes.
How much does access control cost per door in 2026?
Per-door hardware and reader costs vary by platform and door type, and wiring condition drives most of the variance in an installed quote. A site walk-through from a licensed integrator gives an accurate number faster than any online estimate.
Can access control systems integrate with security cameras?
Yes -- platforms like Genetec Synergis integrate directly with matching video management systems, and most cloud platforms support tying a door event to a camera clip. Matching camera coverage to entry points is worth planning at the same time as the access control install.
Do multi-tenant buildings need mobile credentials or are fobs enough?
Fobs still work reliably and cost less per credential, but mobile credentials cut the cost and hassle of reissuing a lost fob. Buildings with younger tenant populations lean toward mobile-first platforms like Avigilon Alta for that reason.
What happens to access when a tenant moves out?
On a cloud platform, a manager deactivates that tenant's credential remotely and the door stops recognizing it immediately. On a standalone keypad with a shared PIN, nothing changes automatically -- the code has to be manually reset for every remaining tenant.
Is Salto Systems good for older buildings?
Salto's wireless locks are a strong option for older multi-tenant buildings because they skip the wiring runs that make retrofits expensive. The trade-off is battery management across every lock instead of a single wired power source.
One last thing
The detail that trips up most multi-tenant retrofits isn't the software -- it's the door hardware. A cloud platform can be flawless, but if the door closer, strike, and frame aren't rated for electronic access, the install stalls at the hardware store, not the app store. Get the door hardware assessed alongside the software choice, not after.
One line worth remembering going into 2026: the best access control system for a multi-tenant building is the one that revokes access the same day a tenant moves out, not the one with the most features on a spec sheet.
