IBC/IPC Plumbing Fixture Calculator

**UPDATED: Now includes 2015, 2018 and 2021 Code Editions
Instructions:

1. Select the occupancy from the dropdown list in the first column.
2. Select the appropriate description from the dropdown list in the second column.
3. Enter the occupant load in the third column.
4. For unused rows, select the "-" in the first and second columns.

A few notes:

• Calculator is for a single story
• The required number of fixtures for each occupancy is summed and then rounded up to give the total requirement.
• For dwelling units, sleeping units, Group I-2 care rooms and Group I-3 prisons, the requirement is one fixture per unit/room/cell.
• You can only enter each occupancy twice once. For example, having two rows of Business occupancies will create an error in the calculation
