Garage bathroom and sink

[ericm]

I'm trying to get a permit for a detached shop. My planning dept wants me to put the shop sink inside the bathroom with the toilet. My plan was to have it outside as it's more useful there. Is there a code reason why it has to be in the bathroom? We're under the 2018 IBC but I can't find anything in there about this.

Just speculation, but a sink in the garage is more abt to lead to oily discharge into the sewage system, and may require an oil separator. My shop has a slop sink as well as a sink in the bathroom, and also has a separator.

I didn’t build it, so I don’t know the history. It also has a couple of floor drains / grates, which is the other potential cause for the separator. I do know that the DEQ required the previous owner to install the separator. It wasn’t his idea....

My garage has a toilet and a kitchen sink, I am in Coronado and had no difficulty with the permits. If you ever find your self in the San Diego area, you can come test my plumbing. PM Me for the address

The city allowed me to have the sink outside of the toilet space. The waste pipe for the house passes directly under the shop toilet on the way to the lane hook-up. Connecting the shop was easy and included a vent pipe to the outside roof.
The city permits told me that I have the last permit for an 865SF garage. I had to go through The Board of Variance to get this. After this event, all new garage construction has a maximum of 400sf.

This is just a guess...perhaps they want a sink IN the toilet room so you can wash your hands after pinching a loaf. Ask them if you add a bath sink in the toilet room, if they will allow the laundry sink outside of the toilet room. If they still say no, plumb and install a bath sink, but make plumbing provisions for the laundry sink post final inspection.

IBC is commercial IRC is residential either way look under the planning section r307. However I think above poster is correct.

Pretty much. IBC does cover residential when it's more than a 3 family dwelling and I forget how many stories, it's like 3 or 4. I believe there's also something about separate egresses as well.

But for the OP, the IRC is likely what he needs. However, the local AHJ, probably adopted the IBC and not the IRC and that's why they are referencing it.

To the point, I think they are trying to prevent any future headaches for the OP, like mentioned about oil/pollutants going into the sewer system. . . . it's a "bathroom" sink no car parts will ever be washed in it . . . wink wink.

I never got back on this (because I forgot I posted about it) but after talking to the GC and reading codes, seems like the county is concerned with a car crashing into the sink. A sink outside the bathroom would require bollards. My GC says he did that for another client and they were big bollards. But somehow the 2x4s and dry wall of the bathroom wall will protect the sink.

I'd wanted to have the sink outside since I'll mostly be washing dirt etc off my hands but I can do that inside the bathroom too, and I'd rather do that than work around bollards.

This is what I would do.

That makes no sense (car crashing into sink). But that's the way rules are sometimes...

I concur ^^^, so if you have a washer & dryer in the garage, they too would need bollards?
I believe his 'county' should maybe be more concerned with piss poor drivers!

I only had the bathroom roughed-in under permit. (sewer and water line) What I do with it later is my business.

Stud in the wall with the sink inside the bathroom…inspected….move the wall and put the sink where you want it

Go to your building dept/planning dept and ask to get a copy of that code requiring it. Tell them you would like to have it to assist in planning and laying out your garage plan. See if it actually says it or not and make your plan from their.

However, being in California, it be related to those earthquake codes as well.
