Latest Regulations on Container Houses

The latest regulations on container houses mainly cover aspects such as planning approval, usage restrictions, safety standards, and regional differences.

I. Planning Approval and Usage Restrictions

If container houses are to be used as fixed buildings, planning permission is required. Container houses without planning permission, those occupying land outside the planned area, those that have unlawfully changed the land nature or building function may be deemed illegal constructions. If used solely for temporary storage, such as storing agricultural supplies and tools on farmland or rooftops, without hardening the ground or connecting to water and electricity supplies, approval is generally not required. However, if used for commercial purposes, such as homestays or shops, land use approval, planning filing, and fire safety permits are necessary. For residential use, formal building declaration is required, along with a construction permit, and the building height should not exceed 6 floors with a total height of ≤24 meters.

II. Safety Standards and Structural Requirements

Container houses must comply with safety standards such as the Technical Specification for Modular Combination Container Houses (CECS 334:2013). Stair components should preferably utilize the container structure for support, elevators can adopt the container structure, and interior decoration and fire protection design must meet specific requirements. In addition, the load-bearing capacity and structure of container houses are crucial. The thickness of steel for main beams and columns, welding processes, and anti-corrosion treatments must meet standards to ensure safety during lifting, stacking, and transportation.

III. Regional Differences and Policy Implementation

There are differences in the implementation of policies on container houses across different regions. Coastal cities such as Shanghai and Shenzhen are more accommodating towards container houses and have introduced special policies to encourage their use in cultural tourism and commercial sectors. In contrast, some agricultural provinces have stricter controls. For example, a new regulation in a certain province in 2025 requires temporary building registration for container houses in farmland. Additionally, container houses are absolutely prohibited in sensitive areas such as basic farmland and ecological protection zones.

IV. Suggestions for Compliant Use

To avoid legal risks, when using container houses, it is important to ensure that the land nature is not changed and that permanent occupation is not formed, while complying with local policies. If used for temporary storage, it is recommended to choose a single 20-foot standard container without hardening the ground or connecting to water and electricity supplies. For commercial or residential use, it is essential to follow the formal application process and obtain the necessary permits.
