At $8,000 to $12,000 per month, a Connecticut nursing home will cost your family more in a single year than most ADU additions cost to build. There’s another way.
The conversation is never easy. Mom is getting older. Living alone isn’t as safe as it used to be. The house she’s been in for forty years is too much to manage. You’re worried every time the phone rings.
For a lot of Connecticut families, the answer is an ADU — an accessory dwelling unit — built on the same property as an adult child’s home. A small cottage in the backyard. A finished basement with its own entrance. An addition off the side of the house with a covered walkway. Close enough to feel safe. Separate enough to feel like home.
We’ve built these. Here’s what we’ve learned.
Why Families Choose an ADU Over a Nursing Home
The financial math is hard to ignore. A semi-private room in a Connecticut nursing home costs $8,000–$12,000 per month. Assisted living is typically $4,000–$7,000. Memory care runs even higher.
A well-built 600–900 square foot ADU in Connecticut costs $120,000–$250,000 depending on type. Amortized over even ten years, that’s $1,000–$2,100 per month — a fraction of institutional care. And at the end of ten years, you still own the structure. It’s still on your property. It still has value.
But the financial argument isn’t even the main reason families do this. The main reason is simpler: they want their parent close.
Designing It Right: Accessibility From Day One
An ADU for an aging parent has to be designed differently than a rental unit or a guest cottage. The features that matter:
- No-step entry. A gradual ramp or zero-threshold entry is non-negotiable. Steps become dangerous fast — build it right from the start.
- Wider doorways. Standard doors are 32″. For wheelchair or walker access, you want 36″ minimum throughout.
- Walk-in shower. No tub to step over. A curbless, roll-in shower with a seat and grab bars is far safer.
- Grab bars. In the shower, next to the toilet, in the hallway. Blocking in the walls during construction costs almost nothing. Adding grab bars later to an unblocked wall is a major headache.
- Single-floor living. Everything on one level. No stairs between bedroom, bathroom, and kitchen.
- Good lighting. Older eyes need more light. LED, ample fixtures, light switches at a height that doesn’t require bending.
- Lever handles. Doorknobs are hard with arthritis. Lever handles throughout.
These features don’t make the space look institutional — they make it look thoughtful. And they add value for any future use of the unit.
Separate Entrance, Separate Life
The detail that makes or breaks these projects: the ADU needs its own entrance. Not a door connecting through your kitchen. A proper, separate exterior door with its own path to the driveway.
This matters for dignity as much as practicality. Your mother isn’t moving into your house. She’s moving next to your house — a very different thing, psychologically, for everyone involved.
Separate entrance. Her own mailbox. Her own doorbell. Her own space that she controls.
A Real Connecticut Example
We built an 820-square-foot detached cottage for a family in eastern Connecticut. Their mother was 74, recently widowed, living an hour away in a house that had become too much. The family wanted her close but didn’t want to disrupt anyone’s privacy.
The cottage went in the backyard — its own foundation, its own heating system (mini-split), its own entrance off a small stone path from the driveway. No-step entry, 36″ doors, walk-in shower with bench. A small covered porch facing the main house so she could see when the grandkids were outside.
Total project cost: $187,000. Total timeline from permit to move-in: 11 months.
The family’s words six months later: “We should have done this five years ago.”
Getting Started
If this is something you’re considering, the first step is simple: call your town’s zoning office and ask if ADUs are permitted on your property. Then call us.
We also wrote a full guide — The ADU Playbook — that covers the entire process from zoning to move-in, including a dedicated chapter on designing for aging family members. It’s being published on Amazon shortly and will be available for free on our website as part of our commitment to helping Connecticut families navigate this decision.
