How often does NFPA 110 require inspection?

NFPA 110 sets a schedule from weekly, monthly, semi-annual, annual intervals. The full task-by-task table with code sections and who may perform each task is shown above, and the calendar builder dates it from your real last-completed dates.

Which of these tasks can be done in-house?

Tasks marked Tier 1 or Tier 2 can be performed by trained facility staff with documentation under the national code. Tier 3 tasks require a certified or licensed professional. Starred tasks are qualified in-house under the national code but licensing is commonly required locally — confirm with your AHJ.
