Which of the following is not considered a basic maintenance procedure?

Innovative maintenance is not considered a basic maintenance procedure because it implies a focus on creating new methods or technologies to improve existing practices, rather than adhering to established protocols intended for upkeep. Basic maintenance procedures, on the other hand, encompass routine activities that keep properties functional and safe.

Routine maintenance involves regular tasks to prevent deterioration, such as cleaning and inspections. Preventative maintenance is aimed at anticipating and preventing future issues, like scheduled replacements of filters or repainting. Corrective maintenance is reactive, addressing issues as they arise when repairs are needed.

Thus, while the other categories focus on maintaining systems and preventing failures, innovative maintenance takes a different approach aimed at improvement and enhancement, which is why it does not fit within the fundamental maintenance procedures that property management typically employs.
