North American Industrial Classification System (NAICS) Codes for Municipalities

The NAICS codes are used to describe your primary business activity at a certain location or establishment as used in OSHA’s recordkeeping regulation. The codes start with a 2 digit number; for example, all utilities fall under NAICS 22 and eventually are broken down into 6 digits that describe specific activities. The Bureau of Labor Statistics and OSHA use the codes to determine specific work tasks and typical exposures of that industry. For instance, even though a police department may be housed in city hall (NAICS 921110), police officers (NAICS 922120) will have substantially different tasks and would need a separate 300 log for recordable injuries or illnesses. The same practice would apply to other work activities conducted by municipal employees. The following NAICS codes are those that are applicable to most municipal work activities. If you have any questions about your NAICS code and how they relate to work tasks or have additional departments that may not be listed below, please contact Margret Meade by email [email protected] or by phone at 515.210.6617.
