National price ranges
Fixr: master suite (bedroom plus bath) addition $45,000 to $100,000; converting existing space $24,000 to $160,000.
When it is worth it
- The person cannot or should not climb stairs and does not want a stair lift.
- Wheelchair use is likely.
- The household plans to stay for many years.
When to try something else first
- A downstairs room plus a half bath with a shower added would do.
What moves the price
- Converting existing space versus building on.
- Plumbing for a new bathroom.
- Foundation, roof and permits for an addition.
DIY or hire it out
Not a DIY job. Use an architect or design-build firm and ask for universal design details: 36 in doors, a curbless shower, and a 60 in turning space.
Where this shows up in the home check
Keepstead suggests this fix when one of these checks fails. Run the home check to see whether it is a priority for your home.
- The stairs are easy to climb today, or bed, bath and kitchen are all on one floor (hallways and stairs)
Frequently asked questions
Is a first-floor bedroom addition tax deductible?
Generally no: additions raise the home's value. Specific accessibility features inside it may count; ask a tax professional.
Is it cheaper than a stair lift?
Far from it. Fixr puts straight stair lifts at $2,000 to $8,000, against $45,000 or more for a new suite.
