Apartment maintenance jobs are positions that require you to perform regular maintenance and upkeep on apartment buildings. Your duties and responsibilities include repainting walls, addressing minor plumbing issues, such as clogged sinks, repairing or replacing electrical switches or outlets, and performing general cleaning and maintenance around the property. You consult with a building supervisor or property management company whenever repairs need to be made and provide them with a list of necessary supplies, costs, and time estimates. In smaller buildings, you may perform the work of a technician and supervisor, while in larger complexes, you should have a more specialized role.
