Legal analysis: This needs to be approved by relevant departments. Not all houses without property registration are illegal buildings, and not all illegal buildings must be demolished. The housing situation within the scope of expropriation is complex, especially in urban villages or old urban areas. Due to historical reasons, a large number of buildings have not gone through the formalities of property right registration or examination and approval according to law. The government should organize relevant departments to investigate, identify and deal with such buildings within the scope of expropriation.

Legal basis: Regulations on Expropriation and Compensation of Houses on State-owned Land Article 24 The municipal and county people's governments and their relevant departments shall strengthen the supervision and management of construction activities according to law and deal with acts violating urban and rural planning according to law. Before the people's government at the city or county level makes a decision on house expropriation, it shall organize relevant departments to investigate, identify and deal with unregistered buildings within the scope of expropriation according to law. Compensation should be given to temporary buildings that have been recognized as legal buildings and have not exceeded the approved period; No compensation will be given to illegal buildings and temporary buildings that exceed the approved period.
