According to the third issue of China Longitudinal Aging Social Survey in 2018，this report studies the home environment of the elderly in Beijing，Tianjin and Hebei，mainly focusing on the indoor environment，outdoor environment，community environment and smart home environment. The home environment of the elderly in Beijing，Tianjin and Hebei is mainly reflected in the following aspects：the installation rate of handrails in the houses of the elderly in the three places is low，the coverage rate of toilet is not high，the barrier-free environment in the community is relatively poor，the probability of the rural elderly not using the network is relatively high，and the home environment of the elderly in Hebei Province is in multiple weaknesses. Finally，based on the survey results，four countermeasures are proposed. Firstly，we should take the installation of handrails and the replacement of toilet as the starting point to promote the transformation of indoor environment for the elderly in Beijing，Tianjin and Hebei. Secondly，we should carry out the inspection of barrier free environment in Beijing，Tianjin and Hebei communities by focusing on the corridor entrance，fitness venues and facilities，and the road traffic. Thirdly，we should bring the construction of home-based aging environment for the aged into the collaborative development plan of Beijing，Tianjin and Hebei elderly care services，and strive to promote the equalization development of home-based aging environment for the aged in the three places.
