From smart locks and mobile access to connected thermostats and leak sensors, smart apartment technology is becoming a standard feature in multifamily communities. These connected devices make everyday living more convenient for residents while helping property teams manage buildings more efficiently.

But what exactly makes an apartment "smart"?

A smart apartment goes beyond a single connected device. It combines technologies like smart locks, thermostats, lighting, sensors, and resident apps into a connected living experience. Unlike a traditional smart home, smart apartment technology is professionally managed and often integrated with building systems that support access, maintenance, and property operations.

Smart apartment technology is becoming a strategic investment for multifamily operators. According to Parks Associates, companies using smart building solutions report an average 20% increase in operating efficiency, along with 18% lower operating costs and 19% lower energy costs. 

In this guide, we'll explain what defines a smart apartment, the technology behind it, the benefits for renters and property owners, and what to look for when evaluating smart apartment technology.

What Features Does a Smart Apartment Include?

While every community is different, most smart apartments combine several connected technologies that make daily living more convenient while helping property teams operate more efficiently. The most effective smart apartment systems bring many features together through a unified platform, creating a seamless experience for residents and simplifying operations behind the scenes.

Smart Apartment Locks

One of the most valuable smart apartment features is smart access control. Smart apartment locks replace traditional keys with mobile credentials, PIN codes, or digital access, allowing residents to unlock their apartment using a smartphone, wearable device, or secure PIN. For property teams, they make it easy to issue or revoke credentials remotely during move-ins, move-outs, maintenance visits, or vendor appointments.

Parks Associates found that 49% of apartment renters consider smart door locks an important amenity, while 48% value the ability to unlock doors or gates using their phone or smartwatch. These findings show that keyless entry and mobile access are quickly becoming standard expectations in multifamily housing, not just premium amenities. For owners and operators, smart access also creates operational value by reducing lockouts, minimizing manual key management, and simplifying access throughout the resident lifecycle.

Smart Thermostats

Smart thermostats help residents personalize their comfort while improving energy efficiency. They allow users to adjust temperatures remotely, create automated schedules, and reduce unnecessary heating or cooling when they're away. For property teams, connected thermostats can also help manage vacant units more efficiently by automatically shifting them into energy-saving modes between residents. Parks Associates reports that nearly half of multifamily operators already include smart thermostats as part of their smart apartment offerings.

Smart Sensors

Connected sensors quietly monitor building conditions such as water leaks, temperature, humidity, and occupancy. By identifying potential issues early, these devices help reduce costly damage, improve response times, and support more proactive property maintenance.

Video Intercoms and Resident Apps

Smart apartments often extend beyond the apartment itself. Video intercom systems allow residents to see visitors, grant building access remotely, and receive deliveries more conveniently, while a resident mobile app brings together apartment access, guest management, building notifications, and connected devices in one place. Together, these technologies make everyday interactions with the building simpler while reducing manual work for onsite teams.

Benefits for Renters

Smart apartments are designed to make everyday living simpler, more convenient, and more connected. Rather than relying on separate devices or manual processes, residents can manage many aspects of their home through an integrated ecosystem that works together.

Depending on the community, that may include unlocking doors with a smartphone, adjusting the thermostat remotely, granting visitor access from anywhere, receiving building notifications, or using a single app to manage connected devices and amenities. The result is a living experience that feels more seamless, giving residents greater control over their home whether they're inside the apartment or away.

Beyond convenience, smart apartment technology can also provide greater peace of mind. Connected access, smart sensors, and real-time notifications help residents stay informed about what's happening in and around their home, while automation reduces many of the small frustrations associated with traditional apartment living.

These features are increasingly influencing leasing decisions. According to Parks Associates, nearly two-thirds of apartment renters consider controlled property access an important amenity when searching for a new home. As connected technology becomes more common across multifamily housing, renters increasingly expect smart apartment features that deliver convenience, security, and a more modern living experience.

Benefits for Property Owners and Operators

Smart apartment technology does more than enhance the resident experience. It gives property owners and operators the tools to run buildings more efficiently by connecting access, smart devices, and operational workflows into one ecosystem.

Instead of managing disconnected systems, property teams can streamline resident move-ins and move-outs, simplify staff and vendor access, automate routine maintenance workflows, improve visibility across their communities, and respond to potential issues before they become costly problems. As portfolios grow, these efficiencies help teams standardize operations while reducing manual work and administrative overhead.

The operational impact is measurable. Parks Associates found that smart door locks and electronic access control systems save an average of $80,000 per building each year, while 56% of multifamily owners and operators report improved operational efficiency from app-based access control. As more connected technologies are integrated across a property, those efficiencies compound, creating opportunities to reduce costs, improve staff productivity, and deliver a more consistent resident experience.

Why Integration Matters

Installing individual smart devices is only the first step.

The greatest value comes when smart apartment technologies work together through a unified platform.

Consider a typical move-out. Instead of updating multiple systems manually, an integrated platform can automatically revoke building access, place the apartment into energy-saving mode, notify maintenance teams, and prepare the unit for its next resident. What would otherwise require multiple manual steps becomes one connected workflow.

This is the foundation of Building Intelligence.

Parks Associates defines Building Intelligence as the coordinated use of access, smart devices, and property data to automate workflows, improve visibility, and support better decision-making across an entire portfolio.
