That IS a debacle.

Not the most helpful thought, but is there a place elsewhere in the kitchen you can place a cooktop + hood? I didnt think a cooktop in front if a window was even to code. And it must stink to cook there with zero clearance on the left.

Purchase a hood and have it installed.

Man, I wish. We technically have a "u shaped" kitchen, but one of the counters is for seating and it's not quite deep enough to house a cooktop without being awkward. The other counter has the sink/dishwasher, and so the only place for a cooktop to go is where it is pretty much (maybe moved over if they had thought harder about it). They're not supposed to be in front of windows but I think it was allowed in this case because it's an electric stovetop and not gas. Anyways, without a total kitchen remodel that sucker has to stay where it is. Meh. But thanks for the input! It's something to think about for the future.

You could get it more centered over the actual burners *if* you can turn the cooktop around and put the knobs on the left. This may or may not be possible depending upon how the underside is. That would get the burners closer to underneath rather than the knobs.

Inconvenient for a right hander? Sure, but you can get used to it, left handers deal with most things being on the wrong side on a daily basis.

Then get a real exhaust hood . The capture will not be perfect, and the people in here who think a range hood needs to suck a tennis ball through a garden hose will disapprove, but it will work better than nothing, unless you want to have an off center to the window range hood. That's fine too, to have it off center to the window if you want better function. It depends upon your priorities. I have designed several kitchens for other people with proper range hoods and they don't usually remember to even turn them on.

@BeverlyFLADeziner would it work with a style more flush with the ceiling? I just don't know how it would look covering a good portion of 3/4 of a window. Thanks!

@palimpsest interesting idea, thanks!

I tried flipping it here. It's a bit distorted but it shows kind what I mean.

You could also do another custom enclosure but have it larger and centered over the window still but getting fuller coverage

The flue is adjustable. You could have the hood positioned close to the ceiling.

@BeverlyFLADeziner cool, thanks!

I think Beverly has the best answer but it will ot be cheap to repair the hole in the roof since IMO vented with the least number of turns is best and no matter what the ceiling will need repair and then it won't match the rest . IMo it is not gas so just open the window. Then start saving for a redo of the kitchen this whole cooking area ia against code and against good design.Maybe post a to scale floor plan of the kitchen here in a comment and then we can help with the new kitchen that IMO will be in your future. Please do not start another post if you decide to post the floor plan

This may actually be against good design, but it may not be against code, technically. An electric cooktop may well need minimal side clearance to vertical surfaces--this is determined by the manufacturer--and code is pretty silent regarding placing a cooktop under a window. My local code says nothing about the relationship of cooktop to window, and a window actually negates the requirement for mechanical ventilation. Some local codes may be more stringent, but there are a lot of things that international residential code does not explicitly address at all.

Just a thought, but remember those fans from back in the day that were in the side wall and had a pull chain? Do they make a modern version of something like that?

My parents have an island with their range in it and a fan that pops up. Push a button and up it pops

This set-up is not to code. You're not supposed to put a range/cooktop in front of an operable window. It's a fire hazard. Either the window needs to be non-operable or you need to move the range. Do a chimney hood as Beverly suggests.

To me, a functional kitchen beats counter seating, if it comes down to a choice. My brother had a gas cooktop in front of a large window with downdraft ventilation, so perhaps that's an option.

This is definitely not to code. Not only because of the window but because of the wall next to the stove. A stove can't be up against a side wall either.

People quote "CODE". Residential Code is frequently based up on the manufacturer's specifications. There is not a word about the relationship between a cooktop or range to a Window in IRC that I can find. Local codes may vary.

This Maytag electric cooktop requirements are shown, for example. 2-2/2". Some require more, some less.

*Before you get out the sledgehammer, Read Your Appliance Manual, and refer to your Local Code Requirements. These will supercede IRC, but if you don't have any local requirements the requirement is that in IRC.
