Is it legal to build a house without a license after the flood in 20 18.08?

Legal. Most unlicensed houses are due to historical reasons. After building a house, the relevant license is not handled, or the family housing is tight due to the increase of family population, so it is impossible to handle the relevant license for the expansion part, or because the legal ownership awareness is not strong, in order to save the cost of obtaining a license, the license is not handled. Without a legal subject, legal procedures and appropriate time, unlicensed houses cannot be directly identified as illegal buildings. In the flood of 20 18, unlicensed houses were legally built, and illegal buildings must be built by their places.
