How Mobile Access Reduced Costs and Streamlined Operations at Sienna

How Mobile Access Reduced Costs and Streamlined Operations at Sienna

At Sienna, growth has been steady for decades. With its first homes being sold in 1996, the 10,800 acre community has ranked in the Top 50 fastest-growing master-planned communities in the United States and was named community of the year in 2016, 2020, and 2024. Sienna is currently at 80% build out, with approximately 12,000 homes completed and thousands more still to come. 

As the community scales, so does it needs to manage operations and access control for the 40,000 residents who enjoy the amenities every day. 

One challenge Sienna faced was the growing expense of physical access cards, which prompted them to begin looking for a more cost-effective, time-saving alternative.

When Growth Makes Physical FOBs and Cards Harder to Sustain

Before the launch of the Sienna App in 2019, Sienna relied on chipped access cards for resident and staff entry to amenities. At first, this system worked. But as time went on and technology advanced, the cost of physical cards added up quickly.

Costs included:

  • Card printers (which can cost upwards of $12,000)
  • Ink and consumables
  • Ongoing equipment maintenance
  • Replacement inventory
  • Staff time to issue, manage, and reprint cards

Every new move-in required card production. Lost or damaged cards require replacement. Residents were charged for replacements and additional cards for children or caregivers. The costs of cards were not just management-facing but also resident-facing.

As Cyndi Hernandez, a 20-year Sienna team member, shared:

“It wasn’t just the card — it was the printer, the ink, the maintenance. All of that adds up.”

As Sienna continued its trajectory toward full buildout, leadership recognized an opportunity to modernize community access before costs scaled further.

A Shift to Mobile Access Control

In August 2019, the community implemented the Sienna App with Alosant-Powered Mobile Access Control, replacing physical cards with secure mobile access inside the community app.

Instead of carrying a key card, verified residents now unlock amenity entry points using their smartphones.

The shift eliminated most reliance on physical printing infrastructure and introduced fully digital credential management.

Approvals, activations, and deactivations are handled in a centralized admin system, thus streamlining oversight for staff and reducing administrative effort for replacements.

OneCredential: Oversight and Protection Built In

Supporting Mobile Access Control is OneCredentialTM, which securely ties each credential to a specific device that is authenticated through a verified resident profile.

The community can now eliminate credential sharing by temporarily deactivating accounts when a login is detected on an unassociated device. Strengthening control over high-demand amenities allows the team to maximize reservations per resident per day, and control when reservations can be set.

For Sienna, control matters. Pickleball and tennis courts, for example, are active from early morning until late evening every day. Protecting reservations and ensuring fair access is critical for the team.

OneCredentialTM, linked to an individual device, adds a layer of oversight that physical cards cannot.

The Measurable Impact

Lower Ongoing Costs

The transition to Mobile Access Control significantly reduced recurring expenses tied to physical cards, including production, printer equipment, consumables, maintenance, and replacement handling.

As Cyndi noted:

“The cost difference was significant, especially in the beginning.”

By minimizing reliance on physical access cards, Sienna lowered hard costs while maintaining secure, verified access.

Streamlined Operations

Digital credential management simplified resident onboarding, activation, deactivation, move-out transitions, and oversight of high-demand amenities. Instead of coordinating card printing and distribution, the team now manages access digitally, saving time and reducing administrative friction.

A Community App that Supports Lifestyle 

What started as a cost-reduction initiative in 2019 has evolved into a scalable operational system supporting thousands of Sienna residents across the community’s 50 access points. Sienna also leverages the app for events, communication, and a reservation system that supports all of their activities.

A Smarter Way Forward

For communities managing thousands of residents and dozens of access points, physical credentialing becomes increasingly complex.

The experience of Sienna demonstrates that modernizing amenity access can:

  • Reduce hard costs
  • Simplify administrative oversight
  • Protect high-demand amenities
  • Improve everyday convenience for residents

And most importantly, do so at scale.

How does Sienna use mobile credentials for amenity access?

Sienna, a Johnson Development master-planned community in Missouri City, Texas, uses the Sienna App, powered by Alosant, to give verified residents mobile identification for amenity access. Instead of relying on chipped access cards, residents can use their smartphones to enter approved community spaces through Alosant-Powered Mobile Access Control.‍ For Sienna, secure amenity access matters because of the community’s size and activity. Sienna is a 10,800-acre master-planned community in Fort Bend County with a population nearing 40,000, making it larger than many small Texas towns. With more than 50 access points across pools, fitness centers, racquet courts, clubhouses, and other shared amenities, Mobile Access Control helps Sienna manage access at scale while reducing reliance on physical cards.

How did Mobile Access Control help Sienna reduce costs?

Mobile Access Control helps Sienna reduce costs by replacing most physical access card production with secure digital identification inside the Sienna App. Before launching the app, Sienna relied on chipped cards, which created recurring expenses for card printers, ink, consumables, equipment maintenance, replacement cards, and staff time.‍ As Sienna continued to grow toward full buildout, every new move-in, lost card, damaged card, or additional credential for a child or caregiver added cost and administrative work. By shifting to OneCredential Mobile Access powered by Alosant, Sienna reduces hard costs tied to physical credentialing while giving residents a more convenient way to access amenities throughout one of the largest master-planned communities in Fort Bend County.

What is OneCredential and how does Sienna use it?

Alosant OneCredential gives residents one connected way to identify themselves and participate in a community. For Sienna, OneCredential securely connects each resident’s mobile app to a verified resident profile enabling them to use their phone as their FOB. At Sienna, OneCredential helps protect amenity access by reducing credential sharing and giving the community more data around who access spaces than physical cards can provide.‍ Secure amenity access is especially important in the large Missouri City, TX community with high-demand amenities such as pickleball courts, tennis courts, fitness centers, pools, waterparks, and event spaces. If a resident’s account is logged in on a device not associated with the account, the community can temporarily deactivate the account to help prevent shared credentials from being used improperly.

How does the Sienna App streamline community operations?

The Sienna App streamlines community operations by allowing the community team to manage resident onboarding, credential activation, deactivation, move-out transitions, reservations, communication, and amenity access digitally. Instead of printing, distributing, replacing, and tracking physical cards, staff can manage access through a centralized admin system.‍ The new mobile access control approach supports the large amenity network at Sienna, which includes parks, playgrounds, trails, pools, fitness facilities, racquet sports, event spaces, and gathering areas. The Sienna website notes that parks, playgrounds, and rest areas are central to its 10,800-acre master plan, with trails and sidewalks connecting neighborhoods and neighbors throughout the community.

Why did Sienna modernize amenity access with Alosant?

Sienna modernized amenity access with Alosant because physical credentials became harder and more expensive to sustain as the community continued to grow. With approximately 12,000 homes completed, thousands more still to come, and residents using amenities every day, Sienna needed a more scalable access control solution.‍ What began as a cost-reduction initiative has become a broader operational system for Sienna. The Sienna App now supports mobile credentials, access control, reservations, events, communication, and resident lifestyle management, helping Sienna reduce costs, simplify oversight, protect high-demand amenities, and improve everyday convenience for residents across its large Missouri City and Fort Bend County community.
