Objective To investigate the current status and types of older adults′ willingness to undergo age-friendly home modifications, analyze the characteristics of each type, and to provide evidence for targeted interventions. Methods From December 2024 to July 2025, a survey was conducted among 345 community-dwelling older adults using a general demographic questionnaire, the Brief Questionnaire on Cognition and Needs for Age-Friendly Home Modifications among Older Residents, the Perceived Social Support Scale, the Kessler Psychological Distress Scale (K10), and the Activities of Daily Living (ADL) scale. The optimal K value was determined using the Elbow method, and final clustering was completed using K-Means clustering.Results Older adults′ willingness for age-friendly home modifications was classified into three types: Type I, active willingness-high cognition and high demand (21.74%); Type II, passive willingness-low cognition and low demand (55.07%); and Type III, low willingness-high cognition and low demand (23.19%). Monthly pension, education level, self-care ability, mental health status, social support，and number of comorbidities were influencing factors across different types (all P<0.05). Conclusion The willingness of older adults to undergo age-friendly home modifications is heterogeneous. Targeted intervention measures can be developed based on different types to improve the quality of life and home safety of older adults, and to promote the sustainable development of home-based elderly care services.
