Building data · Fixture Count

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.

  1. Click a fixture cell, or the lock at the end of a load factor row.
  2. 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.
  3. Type the Source: the amendment or the official's ruling. Every correction needs one.
  4. 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:

  1. Click + Add a use.
  2. Name the use, type its square feet per occupant, and pick gross or net.
  3. 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.
