Uniform Plumbing Code - Are metering/self-closing faucets required on ALL lavatories?

[namod65]

Hello,

I'm working on a project that is under the 2021 Uniform Plumbing Code, and I'm trying to determine if I need a metering/self-closing faucet on a restroom lavatory.


407.2 States that I must comply with both 407.2.1 and 407.2.2. So I need a faucet with a 0.5 GPM flow rate. And a metered faucet can't do any more than 0.25 gallons per cycle.

But then there is this section next...



407.4 States that all lavatories in public transient spaces (airports, restaurants, etc...) need to have a self-closing/metering faucet. But my restroom is not a "transient" restroom, its just a single office restroom.

So do I need the metering/self-closing faucet per 407.2? Or does 407.4 imply that only "transient" restrooms need metering/self-closing faucets, and thus my office restroom does not need one?

Thanks!

Simple answer NO you are not required to comply with 407.4.

Private or Private Use. Applies to plumbing fixtures in residences and apartments, to private bathrooms in hotels and hospitals, and to restrooms in commercial establishments where the fixtures are intended for the use of a family or an individual.

If this is for an "Office", no.

What is a single office restroom? a single occupancy restroom within an office occupancy? or a single occupancy restroom devoted only to a single user office?

Thanks for some of the feedback.

Yes it is a single restroom within an office occupancy. So there is potential for multiple users to use the restroom (not at one time, it's just a single toilet and LAV), as it is an office space.

And don't forget the hot recirc line within 24" of the lav if you use the 2021 IECC...

Or don't provide hot water since it is not required by code in a restroom.

Must be a UPC thing?
