Fear of losing independence due to inaccessible home layouts in Altadena

Many Altadena seniors face anxiety about being forced to leave their homes because of mobility limitations — such as navigating steep front porches, narrow hallways, or multi-level layouts without stairlifts or vertical platform lifts. Research shows aging in place challenges affect homeowners across 18,000 communities nationwide, with fear of losing independence being a primary driver for seeking home modifications. Without accessible design, routine activities like accessing bedrooms or bathrooms become safety risks, increasing the likelihood of falls and premature relocation to assisted living facilities.
