Building an ADU for Aging Parents: The Utah Multigenerational Home
There's a moment a lot of Utah families hit at once: a parent shouldn't live alone anymore, but nobody wants a nursing home, and moving them into a spare bedroom strains everyone. A backyard ADU is the answer more and more families are choosing — close enough to help, separate enough to keep the peace.
Close, but not on top of each other
The magic of an ADU for aging parents is the balance it strikes. Mom or Dad has their own front door, their own kitchen, their own space and dignity — and you're thirty steps away when they need you. No listening for a fall through a shared wall, no giving up your dining room, no two-hour drive to check in.
Built for the years ahead
An ADU meant for aging parents should be designed for how they'll actually live in it — and this is where building it new, on purpose, matters:
Single-level, no stairs
A ground-floor plan like the 735 sq ft Compact keeps everything on one level — no stairs to navigate now or later.
Room to age in place
Wider paths, curbless entries, and a layout that works with a walker or wheelchair down the road are far easier to build in from the start than to retrofit.
Comfortable and low-maintenance
The Arena Standard — a tight, all-electric shell with room-by-room heat pumps — means a warm, quiet, low-bill home that's easy for a parent to run.
The cost compared to the alternative
Assisted living in Utah runs many thousands of dollars a month, indefinitely. A backyard ADU is a one-time build at a fixed $175 per square foot that stays on your property, adds to its value, and — if your family's needs change later — can become a rental earning an estimated $1,400–$2,850 a month. It's care and an asset in the same footprint.
Start with the right plan for your lot
The best plan depends on your parents' needs and your yard. Talk to an Arena advisor about a single-level layout, or if you're weighing what your property can hold, see how to develop your lot.
