Where does the hallway lead to. How wide it that?

Are you saying it’s 31” to the corner where the door is? What does that door lead to? Do you have a floor plan you could share?

As noted above, it's way below standard, according to the NKPA guidelines. (See 7). But if you followed all their rules, you'd be dismantling most everything. If there is wheelchair use in the future--and who knows--definitely a big problem

We need an actual to scale floor plan to answer. Make sure you mark all measurements , windows doorways clearly.

No, there are other ways into the kitchen to accommodate appliances.

Are there other ways into the kitchen?

Take off an inch for the countertop overhang, so,30". I wouldn't put a cabinet there.

I'd rather have space to move around comfortably and pass someone with my arms full of bags/laundry/stuff than have one extra cabinet.

I would hate that pinch-point...

make or buy a cabinet at 12 in deep and ABOUT 15 in wide..12 in deep with open shelves is simple to do ...... . You don't have to feel it's space totally lost. change what you put there. plenty of uses for a 12 inch deep something. If you have leftover inches [ like 9 in or so]..... then insert an upright 24 in deep tray cabinet or rollout pantry .....

Are you up for a little bigger investment? You could reduce the pantry to one or two Rev-a-shelf pantry pullouts. It might actually store more stuff and could open up the passage.

If they are rehab cabinets can you cut the back to make it less deep?

Thanks for all the ideas! Because this cabinet is adjacent to the oven, it would be best to have a full-depth cabinet to hide the side of the oven. And the pantry idea is great, but tearing down extra walls is beyond the scope and budget of my project. I may just have to live with a smaller than desired opening. Before the remodel, the kitchen layout presented this same problem and we've lived with it fine for years, so it may just have to stay that way.

You can hide the side of the oven with a wood panel, painted to match.

Maybe it's because I'm used to old houses and am pretty tiny, but I wouldn't be that bothered by this. I've got two doorways in my kitchen that are only 30" and it's rarely an issue. I wouldn't put anything breakable on the corner of that cabinet, in case of rogue elbows, but unless this is the favorite leaning spot of your family or where the saint bernard hangs out (in which case I'm not sure any width will really help), I'd keep the cabinet.

I'll voice dissent. All my doors are 30" in this house, so the openings are less than that. It's not ideal, but it's better than my last house that had several 24" doors. If you've already lived with it, and it didn't bother you, I don't know why it would start to. Older houses have quirks. I'd rather have a pinch point than no counterspace on one side of the stove. (Had that at my last house too. Hated it.)

(ETA: if changing the pantry situation might be in the budget later, better to have the base cabinet next to the stove now than to change both the pantry *and* the base cabinet later.)

Since you already have the cabinets, don't have the money to blow on making your pantry different, and already used to the slightly narrower space anyway... go for it and use the cabinet. Us telling you preferred clearances or asking for detailed measured floor plans aren't going to change what you got and can do.
