35%住宅楼步入“中老年”

Core Viewpoint - The rapid urbanization in China has led to a significant number of residential buildings entering a maintenance phase, with many structures showing safety hazards due to aging materials and improper renovations [1][2]. Group 1: Urban Health Assessment - The Ministry of Housing and Urban-Rural Development has initiated a nationwide urban health assessment, covering 297 cities and over 150 county-level cities [2][4]. - The assessment aims to address various urban issues, particularly housing safety, as many residential buildings are now in need of repair or reconstruction [2][3]. Group 2: Building Age and Condition - As of 2024, over 660 billion square meters of housing exists in China, with 35% of this area consisting of buildings over 30 years old, equating to more than 230 billion square meters [2][3]. - Common issues in buildings over 30 years old include exterior wall peeling, insulation failure, and structural cracks, which can lead to significant safety risks [3][4]. Group 3: Assessment Methodology - The urban health assessment will be conducted annually from March to August, with a focus on various indicators related to housing, neighborhoods, and urban areas [6][7]. - The assessment will involve a collaborative approach, with government agencies leading and third-party teams responsible for data collection and analysis [5][6]. Group 4: Urban Renewal Policies - The goal of the urban health assessment is to facilitate urban renewal, particularly focusing on the renovation of old residential areas and the removal of dangerous buildings [8][9]. - The "original demolition and reconstruction" model is being considered as a viable approach for addressing severely aged and unsafe buildings, allowing for comprehensive redevelopment [9][10]. Group 5: Financial and Policy Support - Financial support for urban health assessments is primarily government-driven, with potential for private sector involvement through various funding mechanisms [6][11]. - Recommendations include developing differentiated financial support policies for urban renewal projects and exploring tax incentives to encourage private investment [11].
