Is it illegal to come home late and then charge me two yuan for the property?

If the property management company charges you two yuan for coming home late, then this may involve the property service contract. In the property service contract, it is usually agreed that the owner should pay the property fee according to the agreed time, and the property company has the right to punish the owner who fails to pay the property fee on time or restrict the use of certain facilities.

But whether this kind of behavior is illegal or not depends on the specific situation. If you come home late because of force majeure or other reasonable reasons, such as traffic jam and bad weather. Then it is not illegal for the property management company to charge you two yuan. However, if you come home late because you don't pay the property fee on time, the property management company has the right to fine you, but it is not illegal.

In short, you need to look at the relevant provisions in the property service contract between you to judge whether this behavior is legal. If there are disputes or problems, you can consult or complain to the local property management association and other relevant institutions to solve such disputes.
