stacked washer/dryer in multi-dwelling units

[malachi constant]

I've read the code and searched through the archives here so I know the answer to this. I'll ask anyway, for the purposes of wondering if a code proposal is in order...

I'm designing a multi-family dwelling where the "laundry area" is inside the bathroom and designed to dimensionally hold only a stacked washer/dryer. Disregarding code for a minute, it makes logical sense for two reasons to only provide one 30A/2P breaker:
1) only a stacked unit will fit in this space.
2) when the stacked unit needs replaced the landlord is contractually oblicated to replace it - the tenant is contractually prohibited from bringing in a new laundry unit.

Now, code obviously requires a 20A circuit. Maybe the inspector will make an allowance, but that's hoping for a lot. Would you guys agree with me though that a 20A circuit is superfluous?

210.11(C)(2) Laundry Branch Circuits. In addition to the number of branch circuits required by other parts of this section, at least one additional 20-ampere branch circuit shall be provided to supply the laundry receptacle outlet(s) required by 210.52(F). This circuit shall have no other outlets.

I see no way out.

Isn't it possible that the tenant or owner of the occupancy will install a washer only and not a combo unit? In any case, consulting the BO is your best bet.

As an Inspector We can't assume "what ifs" However. I must agree with Mike and the code......provide a 20 amp laundry circuit per 210.52(F)

i suppose it is possible, but these are some swanky apartments. i don't foresee these tenants not having access to their own personal dryer - ever. if it ever did get to that point there would be extensive remodeling going on in the building.

and to put a hole in that line of thinking, it's more likely that the electric range would be replaced in the future with a slightly larger (or smaller) unit. that's not the end of the world, you just hire an electrician. same thing with the unlikely event of a stand-alone washer.

but yes, totally agree that code doesn't currently allow this installation, so i'll have to show it on the plans unless the inspector makes an allowance. not arguing that at all.

I completely agree, however, I was just pointing out that supposed contractual arrangements don't override code requirements.

The fact is that not all stacked units have a single power cord. Some are convertible and have separate cords for each section.

Similarly (sort of), we usually wire for electric ranges and dryers even if gas units are specified, unless asked to omit them.
