R5 Homes: Integrated ADU Builder in Utah
R5 Homes is a homebuilder based in Utah, specializing in the design and construction of homes with fully integrated Accessory Dwelling Units (ADUs). Operating primarily in Eagle Mountain, Spanish Fork, and surrounding Utah County areas, R5 Homes focuses on delivering what they call the FLEX-ADU — a built-in accessory dwelling unit designed to offer privacy, flexibility, and long-term value for homeowners.
An Accessory Dwelling Unit is a self-contained living space located on the same property as a single-family home. Unlike detached ADU builds or standalone backyard cottage additions, R5 Homes constructs their ADUs as an integrated part of the home's footprint. Each FLEX-ADU includes its own private entrance, kitchen, bathroom, dedicated parking, and independent comfort systems. Soundproofing is also incorporated into the design, making the space suitable for both rental tenants and multigenerational living arrangements.
The FLEX-ADU concept is designed to be adaptable. Homeowners can use the space as a rental unit to generate income, as an in-law suite for aging parents or extended family, or as additional living space for grown children. The unit can also be reintegrated into the main home if circumstances change, giving owners flexibility that a traditional floor plan does not typically offer.
Background and Approach
R5 Homes was founded over a decade ago, during the recovery period following the 2008 housing market crash. The company began by building detached townhomes aimed at affordability, then expanded into cottage home communities before developing their current focus on integrated ADU homes. The shift toward FLEX-ADU design came in response to rising mortgage rates and affordability challenges that followed the COVID-19 pandemic.
The company operates around five stated principles:
- Quality – Construction built with care and craftsmanship
- Customization – Flexible options tailored to the homeowner
- Functionality – Layouts designed to adapt to changing needs
- Service – Ongoing support throughout the process
- Innovation – Design solutions that respond to evolving housing demands
R5 Homes offers a range of floor plans, from two-bedroom options to larger multi-room layouts, each featuring an integrated ADU suite. Their designs are intended to serve families at different life stages and income levels, with the ADU component providing a built-in financial tool through rental income potential.
One notable offering is an optional rent assurance program, which provides homeowners with more predictable rental income. R5 Homes also has a property management team that can handle tenant relations, maintenance, and rent collection on behalf of the homeowner — a practical option for those who prefer a more hands-off approach to managing their ADU as a rental.
ADU Services and Features
As an accessory dwelling unit builder, R5 Homes focuses specifically on the integrated model rather than detached ADUs or garage conversions. Their FLEX-ADU homes are built from the ground up with the ADU as a core part of the design, rather than as an afterthought or retrofit. Key features of their ADU builds include:
- Private, separate entrances for the ADU occupant
- Full kitchen and bathroom within the ADU space
- Soundproofing between the main home and the ADU
- Independent heating, cooling, and utility systems
- Dedicated parking for ADU residents
R5 Homes positions the FLEX-ADU as a financial asset as well as a living space. Rental income generated by the ADU can, in some cases, be factored into a buyer's borrowing power when qualifying for a mortgage, potentially allowing buyers to qualify for a higher loan amount. This is one of the practical financial considerations the company highlights when discussing the value of their ADU-integrated homes.
R5 Homes serves buyers looking for a purpose-built accessory dwelling unit builder in the Utah County region. Their model homes are located in Eagle Mountain, where prospective buyers can view the FLEX-ADU design firsthand before making a decision.
