If the elevator is broken, it is necessary to activate the maintenance fund. If the owner does not sign, no matter how to write a warm reminder, it is invalid. The public maintenance fund, also known as the special maintenance fund for houses, is the "pension" and "treatment fund" for houses. It is suggested that the local property management company negotiate with the owners' committee and hold the owners' meeting to clarify the necessity of elevator maintenance. As long as there is the signature of the property owner, the maintenance fund can be activated by the owner's signature vote, and the owners who account for more than two-thirds of the households agree that the total housing area of the household accounts for more than two-thirds of the total housing area of the community, so the maintenance fund can be used.
