What Is an ADU?
An Accessory Dwelling Unit (ADU) is a private, self-contained living space on the same property as a single-family home. ADUs generate rental income, support multigenerational living, and boost borrowing power. R5 Homes leads Utah in building FLEX-ADU homes, designed with integrated floor plans, soundproofing, and private entrances—making homeownership more affordable and future-proof.
What is A Built-in ADU?
A built-in ADU, like the R5 FLEX-ADU, is a fully integrated suite designed for privacy, flexibility, and independence. Unlike detached units, it’s built into the home’s footprint with its own entrance, kitchen, bath, parking, and comfort systems. Adaptable by design, it can serve as a rental, multigenerational suite, or unified home—offering income potential, privacy, and lasting value.
Why Choose R5 Homes as Your ADU Builder
Choosing the right ADU builder is about more than adding extra space — it’s about creating a private, functional, and future‑ready living solution that truly fits your life. R5 Homes takes a purpose‑built approach to ADU design and construction, delivering integrated ADU spaces that feel intentional, independent, and built to last.
A Smarter Approach to ADU Living
Most ADUs feel like an afterthought — but R5 Homes designs them as an integrated part of the home from day one. Our FLEX‑ADU layouts are engineered for privacy, independence, and long‑term value, giving homeowners a true second living space without sacrificing comfort or design.
Built‑In Privacy & Independence
Every R5 ADU includes its own private entrance, dedicated parking, sound‑isolated walls, independant HVAC, and a fully self‑contained living space. Whether used for rental income or multigenerational living, your ADU functions as a complete home within a home.
Customizable to Fit Your Life
No two families are the same. That’s why we offer customizable ADU options — from layout adjustments to finish selections — so your space reflects your needs, your style, and your long‑term plans.
A Seamless Design‑Build Experience
We handle the entire ADU process in‑house: architectural design, engineering, permitting, and construction. With one team managing every step, you get a smoother build, faster timelines, and a final product that feels cohesive and intentional.
Future‑Ready Homes With Real Value
An R5 ADU isn’t just extra space — it’s a strategic investment. Our homes are designed to support rental income, aging‑in‑place, home‑based businesses, or evolving family needs, giving you flexibility for decades to come.
R5 FLEX-ADU Home Benefits
A Home That Pays You Back
An ADU turns your basement into a steady income, cutting your costs and giving you freedom to invest in your future.
Rent Covered, Rate Crushed
The future rental income potential from your ADU can boost your borrowing power allowed by lenders, letting you afford a home you truly love. R5’s optional rent assurance program gives you more peace of mind with predictable income.
Together, But Not on Top of Each Other
Host loved ones or rent out your ADU with complete peace of mind. Separate systems and private access keep everyone comfortable and independent.
