Generally speaking, if it does not constitute a crime, but illegally builds a house without permission and rents it out or sells it, it can be stipulated in Article 225 of China's Criminal Law: in violation of state regulations, it has one of the following illegal business practices, disrupting market order.

If the circumstances are serious, he shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention, and shall also or solely be fined not less than one time but not more than five times the illegal income; If the circumstances are especially serious, he shall be sentenced to fixed-term imprisonment of not less than five years, and shall also be fined not less than one time but not more than five times for illegal gains or confiscation of property:

(a) without permission, dealing in franchised or monopolized commodities or other commodities whose operation is restricted by laws and administrative regulations.

(2) buying and selling import and export licenses, import and export certificates of origin and other business licenses or approval documents stipulated by laws and administrative regulations.

(three) without the approval of the relevant competent departments of the state, illegally engaged in securities, futures, insurance business, or illegally engaged in fund payment and settlement business; (four) other illegal business activities that seriously disrupt the market order. In this case, Zhang violated the fourth paragraph of Article 225 of the Criminal Law, which constituted the crime of illegal business operation.

Debt collection should also be legal;

However, as people who eat melons, we should pay attention to two principles when we look at these things, that is, debt is not a breach of contract or even illegal, and debt collection should be carried out in a legal way. As mentioned in the title of the article, creditors live and eat in debtor's house in order to collect debts, and debtors know that they are wrong and bear it; If the debtor can't bear to call the police, according to the seriousness of the case, the creditor's behavior will indeed be suspected of related crimes.

The debtor's debt infringes on the creditor's legal rights, which belongs to the civil field and generally does not constitute a crime; However, the creditor moved into the debtor's house for debt collection, which violated the debtor's housing rights and freedom of housing management control and may be suspected of committing a crime. The above two interests cannot be confused and must be dealt with separately.
