NAICS Code for Cleaning Business

The NAICS code for a cleaning business is 561720, Janitorial Services. It covers cleaning the inside of buildings: offices, homes, restrooms, windows and even aircraft interiors, and it's the code federal agencies use for custodial contracts. Residential maid services and commercial janitorial companies both belong here. A common mistake is picking 561740 or 561790 because they sound close; those are for carpet cleaning and exterior or specialty cleaning.
