ADU Construction Built for Empty Nesters
Why Downsizing Feels Impossible for Altadena Empty Nesters
Too Much Home, Not Enough Right Space
Downsizing Is Not an Option for Most Empty Nesters in Altadena
70% of empty nesters surveyed say downsizing is not an option, and many want to stay in the home they love. At the same time 26% of empty nesters feel their home is too big and 38% have more than two rooms they do not need. That mismatch creates frustration: excess bedrooms become storage, formal living and dining rooms sit unused, and square footage that could support aging in place or multigenerational living is wasted instead of reallocated.
Wasted Formal Rooms and Missing Daily Spaces
The family-floor-plan mindset fades after kids leave. Empty nesters lose usable daily space while formal rooms go unused. 61% of empty nesters who own their homes have more than two unused rooms, and 61% of those surveyed expressed a wish to have their own office at home. Hobby, exercise, and guest space is missing, while oversized dining and living areas remain empty. Reallocating square footage to a guest suite, home office, or accessory dwelling unit (ADU) addresses the real daily-life gap.
Two-Story Homes Become Hard to Maintain as You Age
From 55 to 75, stairs, shower curbs, and large yards shift from inconvenient to risky. Excess bedrooms quietly became storage rooms years before kids moved out, wasting square footage that could be reallocated to barrier-free living, single-story living, and universal design. Empty nesters who want to age in place in Altadena need a split-bedroom plan or a detached ADU for a ground-level suite rather than leaving the neighborhood they know.
