Multi-unit properties — apartments, condos, and gated single-family communities — need an intercom system that scales differently than a single-family home. The core challenge is directory design: letting a visitor reach the right unit or resident without requiring a dedicated line for every single one.

How Directory Intercom Systems Work
Quick answer: A directory system lets a visitor scroll or search for a specific unit or resident name, then places a call to that resident's phone, in-unit panel, or app — without needing a separate physical line for every unit.
Modern directory systems route the call over the property's network rather than dedicated wiring per unit, which is what makes them practical at scale. Residents typically answer via a smartphone app, letting them grant access remotely even when they're not home.
Gated Communities vs. Apartment Buildings
A gated single-family community typically uses a telephone entry system at the vehicle gate, letting a visitor call a resident's phone number directly to request gate access — see our gate installation cost guide for how this pairs with the gate itself.
An apartment or condo building typically uses a directory-based panel at the building's main entrance, since there are far more units in a smaller physical footprint than a gated neighborhood.
Pairing With Access Control
Multifamily intercom systems are frequently paired with tenant-level access control so residents use the same credential for their unit door and common areas as they do to grant visitor access through the intercom. See our commercial access control planning guide for how these systems integrate at scale.
Cost Factors
- Number of units — directory systems scale in licensing and setup cost with unit count.
- Number of entry points — a property with multiple building entrances needs a station at each.
- Audio vs. video directory — video adds camera hardware and network bandwidth needs.
- Integration with access control — tying the intercom to tenant credentials adds programming time.
See our intercom installation cost guide for pricing ranges by system type.
Code and Accessibility
Directory intercom stations serving the public must meet ADA accessibility requirements, including mounting height and usable controls for residents and visitors with disabilities. Installers in Texas are licensed through the TDLR — ours is License #B31188501.
Multifamily Intercom Across Dallas, Fort Worth and Allen
Gated single-family communities are common across Allen, Plano and Frisco, typically using telephone entry at the vehicle gate, while apartment and condo directory systems are more concentrated closer to Dallas and Fort Worth's urban cores.
Common Mistakes
- Choosing a system that doesn't scale cleanly as units are added or turned over.
- Not planning for network bandwidth needs of a video directory system across many concurrent calls.
- Skipping ADA accessibility review at the entry station.
Questions to Ask Before Hiring
- Can the system scale as units or entry points are added?
- Does it integrate with our access control platform?
- Do residents answer via app, phone, or both?
- Are you licensed and insured in Texas? (We are — TDLR License #B31188501.)

Frequently Asked Questions
What's the difference between a gate intercom and an apartment intercom?
A gate intercom typically calls a resident's phone directly for vehicle gate access, while an apartment intercom uses a directory system to reach a specific unit at a building entrance.
Can residents answer the intercom from their phone?
Yes, most modern directory and gate telephone entry systems support answering and granting access via a smartphone app.
How does an intercom system scale for a large apartment building?
Directory systems route calls over the property's network rather than dedicated wiring per unit, which is what allows them to scale to many units.
Can intercom be paired with tenant access control credentials?
Yes, many multifamily systems tie the intercom to the same access control platform used for unit doors and common areas.
Do gated communities need a directory system?
Not usually — most gated single-family communities use a simpler telephone entry system that calls a resident's phone directly.
What happens when a new resident moves in or out?
The directory or telephone entry list is updated in the management platform, without requiring hardware changes.
Do multifamily intercom systems need to be ADA accessible?
Yes, entry stations serving the public should meet ADA accessibility requirements for mounting height and control usability.
How much does a multi-unit intercom system cost?
Cost scales with unit count, number of entry points, and whether it's audio or video; see our intercom cost guide for detailed ranges.
Do you install intercom systems for HOA and gated communities?
Yes, gate telephone entry systems for HOA and gated communities are one of our most common intercom installations.
Do you serve Allen and the greater DFW area for multifamily intercom?
Yes, we install intercom systems for apartments, condos and gated communities across Dallas, Fort Worth, Allen, Plano, Frisco, McKinney and the surrounding North Texas area.
