Property management contracts are signed every few years.

Legal analysis: There is no mandatory provision, but generally it should not exceed three years, because the labor cost of property management is very high and the labor cost rises rapidly, so if the signing time is too long, the income will not become a cost and cause losses.

Legal basis: Article 2 of the Regulations on Property Management The term "property management" as mentioned in these Regulations refers to the activities that the owner selects a property service enterprise, and the owner and the property service enterprise repair, maintain and manage the house, supporting facilities and related sites in accordance with the property service contract, so as to maintain the environmental sanitation and related order in the property management area.
