Container House Placement Standard

The placement of container houses must meet requirements for structural safety, compliant land use, construction specifications, and approval procedures. The specific standards are as follows:

1. Structural Safety and Performance Standards

Container houses must comply with building codes for earthquake resistance, wind resistance, and fire prevention. For example, structural stability must meet the requirements of the "GB50011-2010 Code for Seismic Design of Buildings," with a typical seismic fortification intensity of 7 degrees. Wind resistance should reach levels 10-12, such as the Suzhou Zhongnan Steel Structure products, which, when tested, showed a frame deformation of only 2mm under 12-level strong winds, well below the national standard limit of 10mm. In terms of fire performance, wall materials must meet Class A non-combustible or Class B1 flame-retardant standards, with a smoke concentration rating of Q1 to ensure low smoke emissions. Additionally, the design service life of the house is generally 5 years, with a fire resistance rating of Class II, and it must pass inspections according to standards such as the "T/CECS 1932-2025 Quality Acceptance Standard for Container Houses."

2. Compliant Land Use Requirements

1. Homestead Use: In rural areas, container houses must be placed on self-owned and certified homesteads. It is prohibited to occupy others' homesteads or unauthorized land.
2. Wasteland Use: If placed on unused land such as barren hills or slopes, prior consultation with and approval from land management authorities are required.
3. Public Area Restrictions: Container houses must not obstruct traffic or affect villagers' lives, such as by occupying village roads or public activity spaces.
4. Temporary Building Nature: Container houses are generally considered temporary buildings. If they are used for business purposes (e.g., as homestays) without a business license or government approval, compensation may not be available in the event of demolition.

3. Construction and Installation Specifications

1. Foundation Requirements: The ground must be level, and hardening or pouring of cement foundations should be avoided (as this may be considered unauthorized construction). For example, container houses placed on unhardened ground without water and electricity access and used solely for agricultural storage are generally not considered unauthorized construction.
2. Installation Techniques: Modular rapid assembly techniques, such as bolt-connection processes without welding, should be used to reduce on-site wet work. Construction must comply with the "CECS334-2012 Technical Standard for Modular Combined Container Houses" to ensure the verticality of stacked containers, seismic resistance and anti-loosening of joints, and waterproof sealing quality.
3. Height and Layout: The total height should generally be controlled within 9.6 meters, with three stories as the main structure and partial two stories, to avoid exceeding limits and affecting structural safety.

4. Approval and Compliance Procedures

1. Qualification Certification: Manufacturers must have ISO9001 quality management system certification, and exported products must hold EU qualifications such as CE and CPR.
2. Emergency Project Requirements: If used for emergency shelter, container houses must comply with standards such as the "YJ/T 26—2024 Facilities and Equipment Configuration for Emergency Shelters" to enable rapid deployment within 48 hours.
3. Change of Use Approval: If the use is changed from temporary storage to long-term residence or business purposes (e.g., as a homestay), a new planning permit must be applied for and procedures completed; otherwise, there may be a risk of demolition.
