Whole-Home Renovations Built for Seniors
The Challenge
Why Most Altadena Homes Fail Seniors Who Want to Stay
Homes not built for aging in place
Traditional Two-Story Homes Create Daily Fall Risks for Seniors
In Altadena, 1 in 4 adults aged 65+ experience a fall each year, with stairs, narrow hallways, and traditional tubs turning routine activities into hazards. Research shows that of U.S. homes lack essential aging-in-place features, forcing seniors to choose between safety and staying in the homes they love. For Altadena homeowners planning to age in place, these accessibility gaps aren't just inconvenient—they're a direct threat to independence and long-term well-being.

Falls Send Millions to the ER Every Year
More than 14 million adults 65+ fall annually — 1 in 4 seniors — leading to over 3 million ER visits. Two-story living, traditional tubs, and narrow hallways turn everyday routines into hazards.
43%
Cost and Complexity Paralyze Action
