Slogan of self-built house census

The Housing and Construction Bureau took photos of my home and said it was a house census. What he said was that the Housing and Construction Bureau took photos to keep the house.

Reference when re-planning. If it is a self-built house, taking photos is also to check whether there are any violations or whether the house belongs to dangerous buildings. The Housing and Construction Bureau is responsible for the urban construction work within its jurisdiction, and it is their basic duty to often take pictures of some houses. For them, taking pictures is their daily work.
