The housing maintenance fund is used for large and medium-sized repair and renovation projects of the main structure, public parts and public facilities and equipment of the house after the warranty period expires. The main load-bearing structures of houses include foundation, internal and external load-bearing walls, columns, beams, floors and roofs. Public parts refer to outdoor walls, hallways, stairwells, corridors, etc. Public facilities and equipment refer to water supply and drainage pipelines and equipment, distribution cables and equipment, elevators, public lighting, fire-fighting facilities, green spaces, roads, ditches, non-operating parking garages, public cultural and sports facilities and other facilities and equipment owned and used by the owner.

Obviously, the iron fence on the balcony is not owned and used by the owner and should not be considered as the scope of use of the maintenance fund.
