BTI Communications Group, LTD. is a commercial security integrator with offices in Santa Fe Springs, Downers Grove and Phoenix, in business for over 40 years. We install one access control system for shared entries, elevators and parking, with separate admin rights so each tenant runs its own suite, on Brivo, Avigilon, Kantech or RS2 (Acre).

Requirements
Recommended setup
Multi-tenant designs start with who owns each door: the landlord, a tenant, or both.
Landlord zones for entries, lobby, elevators, stairs, garage and roof; tenant zones for suite entries and interior rooms.
One credential per person that works on landlord doors and that person's own suite, issued on a phone or a card.
Readers at shared entries and suite doors, with intercom readers at after-hours entrances and loading areas.
Electrified hardware at shared doors, with suite hardware chosen with each tenant's build-out.
Directory intercoms, tenant-issued guest passes and delivery access windows for couriers.
Lobby, garage and entry video tied to door events so the property team can review an incident quickly.
Elevator floor control by tenant and alarm arming that follows each tenant's schedule.
The hardest part of a multi-tenant building is not the hardware, it is who may change what. BTI sets up the landlord as the system owner and gives each tenant a separate partition or site with its own administrators. The property team controls building hours, shared doors and emergency actions; tenants add and remove their own staff and set schedules for their own suite.
Cloud platforms such as Brivo and Avigilon Alta (formerly Openpath) make this easy with web and mobile admin for tenants. Owned platforms such as Kantech and RS2 (Acre) do it with operator permissions and partitions on a server the landlord or BTI manages.

When a tenant moves out, its group is disabled and every credential tied to it stops working on every door in the building. When a new tenant signs, BTI adds its suite readers to the same system, creates its admin account and imports its users. That keeps turnover a same-week task instead of a locksmith project, and it keeps the landlord's audit trail intact across tenants.
Unattended lobbies need a way to let the right people in. Axis network intercoms and video door stations call a tenant's phone, and the tenant can unlock remotely after seeing the visitor. Couriers can be given a delivery window on the lobby and mail room doors only. After hours, the lobby locks, elevators require a credential, and every unlock is logged.

Platforms
BTI is platform agnostic and recommends the platform after the survey. HID readers and mobile credentials work across most of them. Not sure which fits? Read the commercial access control guide.

Axis access controlInstallation
BTI usually installs the landlord system first, then adds tenant suites as leases turn over.
Multi-tenant projects are scoped in two parts: the landlord system for shared doors and the tenant suites added over time. Door count, elevator integration, intercom count and the platform's licensing per site or per door drive the proposal, which BTI itemizes after a free survey.

Yes. BTI sets up a separate partition or site for each tenant with its own administrators, so tenants manage their people and suite doors while the landlord keeps control of shared doors and building hours.
The tenant's group is disabled and all of its credentials stop working on every door at once. The suite readers stay in place and are assigned to the next tenant.
Yes. A single mobile credential or card can carry landlord permissions for shared doors and tenant permissions for that person's suite.
Yes. BTI documents and tests what is installed and takes over Kantech, Avigilon, RS2 (Acre) and Brivo systems. For Brivo, BTI designs, sells, installs, supports and takes over existing Brivo accounts.
