During the 14th Five-Year Plan period, Huai'an focused on the pressing concerns and immediate needs of the general public, pushing forward the upgrading of ageing residential compounds across the city. A total of 708 ageing residential compounds were renovated, covering a total area of 9.64 million square meters, benefiting 131,000 households, with a total investment of 2.42 billion yuan, exceeding the original target of 680 ageing residential compounds.

To ensure that public welfare projects truly benefit and serve residents, Huai'an issued specialized renovation planning schemes and technical guidelines and established an integrated working mechanism led by the housing and urban-rural development department, coordinated across multiple departments, with primary responsibility resting on local jurisdictions and broad public participation. In the early stages of renovation, staff members visited each ageing residential compound and building to conduct thorough surveys, gathering extensive public input through diverse channels, including household visits, neighborhood discussions, and online comments.

Meanwhile, the renovation projects were divided into three major categories—basic, improvement, and upgrading projects—and advanced in batches and tiers. To eliminate issues such as shoddy and haphazard renovations, Huai'an established a closed-loop management system spanning design, material selection, construction, and acceptance inspection. It innovatively introduced distinctive mechanisms, including resident supervisors, early intervention of specialized audits, and the "three synchronizations" mechanism for utility pipeline renovation, meticulously crafting high-quality public welfare projects that can stand the test of time and public scrutiny. In terms of funding, a diversified investment model featuring "government guidance, market-based operations, and shared resident contributions" was established. Over the five-year period, a total of 767 million yuan in central and provincial subsidies was secured, accounting for 31.7% of the total investment.

During the 15th Five-Year Plan period, Huai'an will continue to deepen its renovation efforts for ageing residential compounds. It plans to renew 100 ageing residential compounds. Key efforts will focus on ageing residential compounds built between 2000 and 2005, with priority given to addressing residential compounds built between 2005 and 2010 that have weak supporting facilities and lagging environments.
