Is it illegal to delimit parking spaces privately?

Legal analysis: illegal. The proceeds from the legal use of property parts and facilities shall be mainly used to supplement special maintenance funds, and may also be used in accordance with the resolution of the owners' meeting. Industry committees can also restrict the rights of property management companies, depending on how the contract signed with the property management company is agreed. For specific questions, I suggest you bring all the information to consult a professional lawyer.

Legal basis: Article 18 of the Measures for the Administration of Property Service Charges shall handle relevant procedures in accordance with regulations after obtaining the consent of relevant owners, owners' congress and property management enterprises. Owners' income should be mainly used to supplement special maintenance funds, and can also be used according to the decision of the owners' congress.
