Is it illegal to put property stickers in the car?

Legal analysis: it is acceptable for the property management company to post some tips when the owner stops at will and can't contact the owner. No, the property management company can't keep the evidence of illegal vehicle license plates with stickers at will, and try not to use double-sided adhesive or foam adhesive when pasting stickers, so as not to be able to clean them up (except for those with bad influence or frequent misplacing, you must learn a lesson).

Legal basis: Article 943 of the General Principles of the Civil Law of People's Republic of China (PRC) stipulates that the property service provider shall regularly disclose the service items, responsible personnel, quality requirements, charging items, charging standards, performance, use of maintenance funds, part of the owner's operation and income, etc. Report to the owners in a reasonable way, and report to the owners' meeting and owners' committee.
