Two-minute version

If you read nothing else.

Pick the platform, then the integrator — not the other way around. The platform decision (Salto KS, Allegion Zentra, Alarm.com Smart Properties, etc.) shapes your operations for the next 5–10 years. The integrator is replaceable; the platform mostly isn't.
Mobile + physical credentials, not mobile-only. Plan for ~10% of residents to need a physical card or fob even in 2026. Every platform we recommend supports both.
PMS integration is the highest-impact feature. Yardi, RealPage, AppFolio integration determines whether resident provisioning is automatic or a daily admin chore.
Plan for the full bundle, not just locks — access plus intercom, smart thermostat, and a resident app. Standalone access is cheaper up front but loses the integration benefit that drives the operating wins.
The network is the foundation. Don't skimp. Under-sized network = under-performing everything that rides on it. This is the single most common mistake we fix during retrofits.
Ask every integrator who owns the integration when something breaks. If the answer is "the manufacturer's support line," walk.

Why this matters now

The economics of smart access changed in the last three years.

Three years ago, smart-apartment access was premium positioning. Today it's table stakes for any property competing with new construction. Three things changed:

Mobile credentials reached parity with physical cards. Residents now expect to unlock their door with their phone. Properties without mobile access lose leases to properties with it.

PMS integration matured. Yardi, RealPage, and AppFolio now natively sync residents to access platforms. What used to be a daily admin task is now automatic.

Wallet integration arrived. Apple Wallet and Google Wallet support means residents don't even need to open an app. Apartment as smartphone-native experience.

The platforms

The four serious options for multifamily smart access in 2026.

Each of these we deploy regularly. Each is a defensible choice depending on the property.

Salto KS

Mature cloud platform with broad hardware ecosystem. The default choice for multi-site operators and multifamily portfolios wanting flexibility on hardware. Per-door annual SaaS pricing scales linearly.

Best for: portfolio operators, multi-site management, mixed hardware preferences, strong PMS integration needs. See full comparison vs Allegion Zentra →

Allegion Zentra

Schlage's modern cloud platform. Native Apple Wallet and Google Wallet support is best-in-class. Tightest integration with Schlage XE360 hardware. Zentra Living for multifamily, Zentra Edge for commercial.

Best for: premium multifamily, Schlage hardware standardization, properties marketing Wallet-key features. See full comparison vs Salto KS →

Alarm.com Smart Properties

A multifamily-purpose-built platform that unifies access, video, intrusion, and resident services in one stack. Strongest fit when you want one dashboard across access AND surveillance AND environmental controls.

Best for: operators wanting one platform across multiple system categories, properties with significant security/intrusion needs, integrated resident services.

ButterflyMX (intercom-led)

Not strictly an access platform — primarily a video intercom — but its access integration (via Salto, Allegion, and others) makes it the standard front-entry layer for modern multifamily. Most projects bundle ButterflyMX with one of the three platforms above.

Best for: front-entry video intercom, delivery code workflows, visitor management. Pairs with any of the above. See vs Comelit comparison →

Decision framework

Six questions that lead to the right platform.

1. New construction or retrofit?

New construction has more flexibility — you can specify hardware and run cabling cleanly. Retrofits should plan around what's already there to avoid wasted spend.

2. Single property or portfolio?

Portfolios benefit from platforms with mature multi-site dashboards (Salto KS, Alarm.com). Single properties have more flexibility.

3. What PMS are you on?

Yardi/RealPage/AppFolio integrations vary by platform. Verify the integration depth — auto-provisioning vs occasional CSV import is a big quality-of-life delta.

4. Resident demographics?

Premium and younger-skewing properties: prioritize Wallet support and app-first workflows. Workforce housing or older demographics: prioritize physical-credential reliability.

5. How critical is the perimeter?

Properties with gates, parking access, or multi-building campuses benefit from platforms that handle perimeter-to-unit on one cloud (Zentra + Gatewise, Salto KS multi-zone).

6. Will you bundle access with cameras, intercom, automation?

If yes, prioritize platforms that integrate cleanly with your other vendors. If no, simpler standalone platforms work fine.

Avoid these

The most common multifamily smart-access mistakes.

Pulled from properties we've retrofitted after the first attempt didn't work.

Mistake 1: Mobile-only credentials. Even in 2026, a meaningful percentage of residents need a physical card or fob — older residents, residents with limited smartphone reliability, residents who lose phones. Every platform we recommend supports mixed credentials. Use them.

Mistake 2: Under-sized network. The access platform needs a properly-segmented, reliably-uptime network. Cheap-out on the network and your access system inherits the unreliability. We see this constantly during retrofits.

Mistake 3: Buying access without intercom integration. Front-door access and front-door intercom should be one workflow, not two. Buying them separately from different vendors usually produces a worse resident experience.

Mistake 4: Skipping the PMS integration. If your access platform doesn't sync with your PMS, resident move-ins and move-outs become daily admin work. Pick a platform with native integration to your PMS.

Mistake 5: Choosing the cheapest installer. Cheap installs surface as integration gaps three months later, when nobody owns the troubleshooting. The installer matters as much as the platform.

Mistake 6: Not negotiating on PMS-included credentials. Many platforms include a certain credential count in PMS-tied pricing. Confirm what's included before signing — you may be paying twice.

RFP-ready

The 10 questions to ask every integrator before signing.

01
Which platform are you recommending and why, given my property specifically?
If the answer is "we install one platform and that's what we'd recommend," you have a vendor problem, not an integrator.
02
Show me the integrated architecture diagram before install begins.
Access, cameras, network, intercom on one drawing. If they can't produce one, integration is going to be improvised.
03
Who owns the troubleshooting when something breaks across systems?
If the answer is "call the manufacturer," they're not actually integrating.
04
What's the PMS integration depth — automatic or CSV import?
Auto-provisioning vs occasional batch sync is a quality-of-life delta that compounds daily.
05
What happens when a resident loses their phone?
The answer reveals how seriously they take physical-credential fallback.
06
What's the network you're putting underneath this?
If they say "we'll use what's there," confirm what's there. Most existing networks aren't sized for modern access + cameras + intercom load.
07
What's included in the install vs. what's billed separately later?
Exclusions surface as change orders. Get them in writing up front.
08
Can I see a recent install in person?
Talk to the operations team at a property they've installed. They'll tell you what they wish they'd known.
09
What's the resident-onboarding workflow look like at cutover?
Bad onboarding = property manager fielding complaints for a month. Ask who handles it and what materials they provide.
10
Will an owner of your company be in the room for the consultation?
If a sales rep is the only voice, the person designing your system isn't the person you're talking to.
