Specifications for the Removal of Prefabricated Floor Slabs in Houses

The removal of prefabricated floor slabs in houses should adhere to the principle of 'prioritizing renovation and transformation, with safety assessment as the core, and strictly limiting the scale of removal'. The specific specifications are as follows:

I. Prioritize renovation and transformation, and limit the scale of removal
According to the '15th Five-Year Plan for Urban Renewal' issued by the State Council in 2026, the focus for prefabricated slab houses is on renovation and transformation, with an emphasis on renovating C- and D-grade dilapidated houses and over 500,000 sets (units) of prefabricated slab houses, rather than comprehensive demolition. The joint notice from the Ministry of Natural Resources and the Ministry of Housing and Urban-Rural Development clearly states that the demolished floor area within an urban renewal unit shall not exceed 20% of the current total floor area, and the demolition-to-construction ratio (the ratio of demolished area to newly constructed area) shall not exceed 2. For example, if the current floor area of a certain area is 100,000 square meters, the demolished area shall not exceed 20,000 square meters, and the newly constructed area shall not exceed 40,000 square meters.

II. Use the results of house safety assessments as the basis for decision-making
Demolition should be based on the assessment report issued in accordance with the 'Standard for Dangerous House Assessment' (JGJ 125-2016):

• D-grade dilapidated houses (with failed load-bearing structures and overall danger) must be demolished, such as houses with foundation settlement exceeding 5 centimeters, load-bearing wall cracks wider than 1 millimeter, or seismic resistance levels less than 70% of the current standard;
• C-grade dilapidated houses (with unsafe local load-bearing structures) should be prioritized for repair and reinforcement, and may also be renovated, rebuilt, or demolished and reconstructed on the original site;
• A- and B-grade houses only require maintenance.
  The assessment report must be issued by a qualified institution to ensure scientific and reliable results.

III. Prioritize the removal of three types of high-risk houses
The 2025 policy clearly identifies three types of prefabricated slab houses for priority removal:

1. Houses assessed as D-grade dilapidated;
2. Houses built before the 1980s with seismic resistance levels less than 70% of the current standard;
3. Houses affecting urban planning (such as subway and viaduct construction).
   Among the 120 million existing prefabricated slab buildings nationwide, 80 million are located in cities, accounting for 20% of the existing housing stock. However, only 15% of the urban existing housing stock (approximately 30 million households) is included in the renovation scope, reflecting the precision of demolition.

IV. Diversified compensation and resettlement methods
The government provides four compensation options:

• Monetary compensation: Not less than 110% of the market price of surrounding commercial housing (for example, the assessment price in Dong'an No.1 Village, Shanghai, reached 135,000 yuan/square meter, 15% higher than the second-hand housing price in the same area);
• Property rights exchange: Replacement at a ratio (for example, 1:1.1 replacement in Handan, with a maximum of 1:1.2 for houses on homestead land);
• Housing voucher resettlement: Choosing housing vouchers entitles residents to additional subsidies;
• Demolition and reconstruction on the original site: For C-grade dilapidated houses, local reinforcement or reconstruction is allowed.
  Residents can choose the compensation method according to their own needs to ensure the maximization of their rights and interests.

V. Protection measures for special cases
For prefabricated slab buildings with historical or cultural value, the government will take protection measures to avoid simple demolition. For example, by repairing and reinforcing, functional replacement, and other methods to preserve the architectural style while enhancing safety.
