Moving a kitchen location

Usually not. Once in a while you'll see a move where the sink backs up to a wall that already has a plumbing stack (e.g. with a bath on the other side.) Even then, unlikely there's a gas line.

Most co-ops (and I assume condos) prohibit putting "wet" spaces over "dry", so that's another (usually redundant) limitation.

Depends on how far you are moving it, your building's infrastructure, what is currently where the new kitchen location would be, your coop rules and the building engineer's recommendation.

As a general rule (there are many exceptions, but let's start with the general rule), the vast majority of coops in NYC will not permit any expansion of a wet area over an existing dry area. This mean the bathrooms and kitchens cannot be encroach one inch on areas outside those spaces during a renovation. Wet area means the entire kitchen and bath -- not just the shower stall or sink area. The logic is that if flooding occurs, your downstairs neighbor shouldn't get the ceiling of her bedroom collapsing because you moved your kitchen over her bed.

Smaller coops may be more lax and flexible. The larger ones rarely will be flexible or even listen to your proposals.

I should add that moving appliances within an existing wet space is rarely a big issue. Moving the stove from one wall of the kitchen to the other, or moving the sink over 3 feet or shifting the dishwasher location won't get most boards up in arms. Bathrooms get a little stickier, but moving sinks, toilets a tad won't get anyone nuts. Adding a steam shower twice the size of your existing tub may be an issue.

Thanks very much. Extremely helpful...

I've heard that moving a gas line for a stove can be a real devil and can escalate into the gas for the entire building being shut off. I suspect that is the exception, but does anyone have any experience?

Moving Kitchens is easier than moving bathrooms, since you can use always use the waste lines from a bath for a kitchen but not always the other way around.

Moving gas lines is actually quite easy, it's just that if you do anything which causes Con Ed to have to come in and do a "pressure test" for the whole building, a lot of older buildings won't pass and then there's big problems.

The reality is that it isn't as hard as people think to move a kitchen a bit, it's more the Coop's rules about wet over dry that make it very hard.

its building specific. check your bldgs alterations agreement.

My coop is slightly on the strict side of average. Dragging the gas line across the kitchen to move the stove was a complete non-issue.
