Is It Illegal to Buy Prefabricated Houses in the US?

Admin September 18, 2026

Buying prefabricated houses in the US is not illegal in itself, but it requires meeting multiple legal and regulatory requirements and is subject to specific restrictions.

I. Imported Prefabricated Houses Must Comply with US Federal and Local Regulations

According to the US Department of Housing and Urban Development (HUD) standards, imported modular houses must pass rigorous safety certifications, covering core indicators such as structural strength, fire resistance, and electrical and plumbing systems. For example, houses must comply with local building codes (IBC or IRC), fire safety standards (NFPA), and electrical and plumbing installation codes (NEC); otherwise, they cannot clear customs or obtain residency permits. Prefabricated houses produced in China are mostly designed according to domestic standards, which differ from US regulations. They may require additional modifications or certifications to avoid compliance risks.

II. Special Restrictions Exist in Regions Such as Florida

Florida has passed the SB264 bill, which prohibits Chinese citizens who are not US citizens or green card holders from purchasing land and real estate in the state, except under specific conditions (such as inheritance or leasing). This restriction directly affects the purchase of prefabricated houses—if the house needs to be fixed on the land, the purchase may be subject to this bill. Although other states do not have similar comprehensive bans, they may impose additional requirements on the approval process and tax standards for imported houses, which need to be verified on a case-by-case basis.

III. Attention Should Be Paid to the Cross-Border Impact of Chinese and US Laws

From the perspective of Chinese law, individuals purchasing real estate abroad must comply with foreign exchange management regulations (such as annual foreign exchange purchase quotas) and declare the legality of their capital sources. If purchasing through a corporate entity, they must also comply with the Ministry of Commerce's regulations on outward investment and cooperation. If the prefabricated house involves cross-border transportation, customs declaration and inspection and quarantine procedures must be completed to ensure compliance with the Law on the Inspection of Import and Export Commodities.

Summary

The legality of purchasing prefabricated houses in the US depends on three major factors: whether the house has passed US safety certifications, whether the buyer's identity complies with state laws, and whether the transaction process complies with cross-border regulations between China and the US. It is recommended to consult local architects, lawyers in the US, and China's foreign exchange management authorities before proceeding to ensure full compliance throughout the process, from house design, transportation, and installation to property registration.
