Fixture Verification Calculator

Compare installed fixtures against the code requirement for the as-built occupant load. The tool applies IPC-style Business (Group B) ratios and the "round up any fraction" rule. It is not suitable for Assembly, Educational, Mercantile, or other use groups, which have different ratios. Always confirm against your jurisdiction's adopted code edition.

Limitations: this tool checks water closets, urinal substitution, and lavatories using Business ratios. It does not check drinking fountains, service sinks, accessible-fixture counts (such as an ambulatory compartment or accessible urinal), separate-facility exceptions for small occupant loads, travel distance, or other use groups. Confirm the use group, local amendments, and configuration against the adopted code edition before issuing an inspection finding. This is a screening aid, not a substitute for professional judgment.
