Requirements
What Orange County property managers ask for
- Shared entries, elevators, restrooms and parking run by the property manager on one schedule.
- Each tenant adds and removes its own people without calling the landlord.
- Move-ins and move-outs that take minutes, with old credentials shut off the same day.
- One platform across a portfolio of buildings in Irvine, Santa Ana, Anaheim and South County.
- Flex and industrial park units with roll-up doors and shared yards.
- Clear records for the owner when a tenant asks who entered after hours.
Recommended setup
Recommended access control setup
A multi-tenant building needs two layers: common areas the property manager controls and suites each tenant controls, on a platform that keeps them apart.
Common entries
Readers and a video intercom at the main entry, with lobby hours set by the property manager.
Elevators
Floor-select integration through the elevator contractor so a credential lights only its tenant's floors.
Tenant partitions
Each tenant gets its own users, schedules and reports inside one system.
Suite doors
Suite readers on the shared platform, or a tenant's own system where the lease allows.
Parking and gates
Gate readers and mobile credentials for tenants, with visitor codes for guests.
Amenities
Fitness rooms, shared conference rooms and bike rooms on their own schedules.
Video
Axis or Avigilon cameras at common doors and gates.
Property managers with portfolios across the county
Orange County owners and property managers often run several properties at once: an office building in Irvine, a flex park in Anaheim Canyon, a retail and office center in Mission Viejo. BTI puts them on one cloud or owned platform so the management team sees every site, sets holiday schedules once and handles alarms from one place.
Each property keeps its own admins and reports, so an on-site engineer at one building cannot change doors at another.
Tenant self-service without losing control
Partitioning lets each tenant manage its own badges, phone credentials and suite schedules while the property manager keeps the lobby, elevators, parking and shared amenities. A tenant that leaves is removed with a few clicks, and its people lose access to common doors the same day.
When a tenant brings its own platform, BTI can connect its suite doors to the building's fire release and leave common areas on the base building system.

Flex, industrial and retail centers
Flex and light industrial parks in Anaheim, Fullerton, Brea, Santa Ana and Lake Forest mix office fronts with roll-up doors, shared yards and gates. BTI puts gates and shared doors on the property schedule and gives each unit its own entry credentials.
For retail and office centers, BTI sets after-hours rules for back corridors, roof access and electrical rooms so only approved vendors and staff get in.
Standards and compliance
California rules that shape multi-tenant access control
| Requirement | Source | What it means for your doors |
|---|---|---|
| Electrified egress doors | California Building Code and California Fire Code, enforced by the city building department and the fire authority | Sensor or push-button release, release on power loss where required, and a tie to the building life safety system where the code calls for it. |
| Accessibility | California Building Code Chapter 11B | Readers, keypads and intercoms mounted at accessible heights with hardware that is easy to operate. |
| Elevator interface | Elevator contractor and California elevator permit | Access control signals are wired through the elevator contractor's interface, never directly into the controller. |
| Workplace violence prevention | California Labor Code 6401.9 (SB 553) | Controlled entries, visitor records and lockdown give the employer's written prevention plan practical controls. |
Your building official and fire authority make the final call on code questions; BTI designs to pass their review the first time.

Frequently asked questions
Who installs access control for multi-tenant buildings in Orange County?
BTI Communications Group, LTD. installs and supports multi-tenant access control across Orange County from its Santa Fe Springs office, on Brivo, Avigilon Alta (formerly Openpath), Avigilon Unity, Kantech, RS2 (Acre) and Axis.
Can each tenant manage its own badges?
Yes. A partitioned system lets each tenant add and remove its own users and suite schedules, while the property manager keeps lobbies, elevators, parking and amenities.
Can one system cover several properties?
Yes. Owners and property managers can run several Orange County properties on one platform, with separate admins and reports for each site.
Can elevators be limited to a tenant's floors?
Yes. BTI works with the elevator contractor to add floor-select control, so a credential lights only the floors its holder may visit.
What happens when a tenant moves out?
The property manager removes the tenant's partition or users, and every credential loses access to common doors at once. Suite hardware can be re-keyed electronically for the next tenant.
Can you take over an existing Brivo or other system in our building?
Yes. BTI designs, sells, installs, supports and takes over existing Brivo accounts, and also takes over Kantech, Avigilon and RS2 (Acre) systems.
Does BTI have an Orange County office?
No. BTI serves Orange County from 12155 Mora Dr, Units 1 & 2, Santa Fe Springs, CA 90670. Call 562-298-5000.
How is multi-tenant access control priced?
Pricing depends on common doors, elevator and garage integration, tenant count, permits and platform licensing. BTI provides an itemized proposal after a free site survey.
