Code tables
See the load factors and fixture ratios the count uses, and correct any value for a state amendment or an official's ruling.
The Code tables tab lists the values Fixture Count computes with, for the edition picked in Code: the IBC occupant load factors and the IPC minimum fixture ratios.
These are model code values, transcribed and not yet verified against the book. Cells with a dot haven't been checked. Your state's adoption and local amendments may differ, so check the values yourself and have the count verified by a licensed professional. The banner at the top links to the code text.
Occupant load factors #
One row per use: its square feet per occupant, whether that's net or gross, and which fixtures it counts under (its occupancy's, or the storage row's).
Minimum plumbing fixtures #
One row per fixture-table row, by occupancy group, with its ratio for water closets and lavatories (male and female), drinking fountains, service sinks and baths or showers.
Correct a value #
When your jurisdiction's rule differs, unlock the cell and enter it. The correction applies to this count only, everywhere that cell is used, and is marked ◆ in the tables and the notes.
- Click a fixture cell, or the lock at the end of a load factor row.
- Enter the rule:
- For a fixture cell, pick 1 per N (tiers allowed), Per unit, Fixed count or Not required, and fill in the numbers. Reads as shows how it will print.
- For a load factor, type the square feet per occupant and pick gross or net.
- Type the Source: the amendment or the official's ruling. Every correction needs one.
- Click Apply to this document.
To undo a correction, open the cell again and click Re-lock to the model code.
Add a use #
If the edition's table doesn't list a use you need, for example one adopted from a newer edition:
- Click + Add a use.
- Name the use, type its square feet per occupant, and pick gross or net.
- Type the Source, then click Apply to this document.
The new use shows in the rooms' use list, marked ◆. To take it out, open it and click Remove this use.
