Building Occupancy Codes and Access Control Tutorial

Author: Brian Rhodes, Published on Aug 11, 2016

A building or room's classification can greatly impact which building codes must be followed. In terms of access control, these 'occupancy codes' dictate how openings can be locked and what equipment is required, often representing a range of hundreds of dollars per door.

How do you know the occupancy classification of a space and which codes apply? Sometimes, even the AHJ may not be sure, and you need to determine this on your own.

This report will guide you through the process to be sure, covering:

  • Why classification is necessary
  • Classification definition and key categories
  • Finding classification ratings
  • Comparing classification types
  • Impact on lock hardware selection
  • Handling mixed occupancies
  • Developing manual ratings
