The public toilet facilities required for a mercantile building are located off a rear corridor rather than in plain view of the sales floor. What does the IPC require so that the facilities can be found by those they serve?
- AA posted floor plan at the main entrance showing the route from the entry to the restrooms
A posted floor plan is a wayfinding aid some owners provide voluntarily. The code asks for identification at the facility, not a directory at the building entrance.
- A legible sign designating each required public facility, readily visible and located near the entrance to that facility
- CNothing at all, because identification of toilet rooms is governed only by the accessibility standard
The accessibility standard adds its own signage rules, including the symbol of accessibility, but the plumbing code independently requires required public facilities to be designated.
- DAn illuminated sign of the same type used for exits at every corridor intersection along the route
Exit-style illuminated signage is a means of egress requirement in the building code. Borrowing it here is a plausible-sounding but wrong answer.
Why B is correct
Required public facilities must be designated by a legible sign that is readily visible and located near the entrance to the facility. The requirement is about identifying the room itself, not about wayfinding from the front door, and it applies to the facilities the fixture table required in the first place.
What this question is testing
The item tests familiarity with the administrative half of the fixtures chapter, which candidates skip while studying counts and clearances, and the ability to separate plumbing code signage from building code egress signage and accessibility signage.
On the job
This is a punch-list item on almost every commercial job. The general contractor buys signs late, hangs them on the door face instead of on the wall next to the latch side, and the inspector writes it up. It matters most in buildings where the public restrooms are shared between tenants, because without designation the tenants tend to lock them and the required facilities effectively stop existing.
Memory technique
Sign the door you must provide.
Exam tip
Signage questions in the plumbing code almost always resolve to legible, readily visible, near the entrance. Learn that phrase pattern.
Where to look it up
Chapter 4, Section 403, the signage paragraph following the separate facilities rules. The UPC treats identification of facilities under different wording, so verify against your adopted code.
