Based on a few, "Is this OK" threads here, I thought it might be helpful to have a standard-type punch list for people who are ready to sign off on their kitchens and/or renos. I'm hoping the KDs here will chime in.

I'll start: Drawers that open well, not impeded by lack of spacers.
Soft closers are installed and work.
Cabinet doors are hung straight. i.e. plumb and level. Check your miters.
Check any veneers for adhesion.
Drawer fronts are installed plumb, level, and in line with the ones above and below, spaced well between each other.
Do pull-outs (you must be new here) pull out smoothly and with full extension?
Hardware is aligned with the other hardware, up, down, side to side.
Cabinet end pieces are installed.
Crown molding is installed and corners look good. Lined up, mitered properly, and caulked & painted where necessary.
(Get this) Kitchen faucet has its stoppers in right, so it doesn't spin over the countertops on either side.
Is your sink caulked? Is it in straight? Is it centered?
See if your garbage disposer works.
Can you turn on your water? Pressure? Does it leak underneath your sink?
Is the oven set right? If it's a stove top, is it in straight? Set correctly? Does it work? Is it caulked?
Your hood. Is it at the proper height? Where does it vent? Does it work? Is it unGodly loud?
Your lights.
Are the ceiling pot lights in the correct places?
Are your pendants centered how you'd like them? Are they level? Do they work?
Are any 2-way switches working properly?
Is your UCL installed well? No wires? IMHO, it should be at the front of the cabinets. Where are the switches?
DW.
Does it work? How does it affect your water pressure?
Does your wine cooler cool? (Do people really need this?)
Coffee station. Does it make espresso to go with your Reese's cups? Does it work?
Tile. Floor and/or back splash.
Is there lippage? Cracks?
Grout all over? Did they use the right color of grout?
Bullnose where necessary?
Is it sealed?
Is any stray caulk removed, rather than painted over?
Is the drywall finished well? No nail pops, no tape showing through?
Is it painted well? All drips cleaned up. Smears off the cabinets and woodwork. Ceiling line cut in well?
Countertops:
If you have laminate, are the edges routed well? Seams well done? Smooth? (Slide a penny across the counter & make sure it'll slide over the seams.)
Stone. (Someone else's gotta jump in here)
Butcherblock? Smooth? Sealed as you'd asked?
Does your fridge open well? Not impeded by lack of space? Does it work?
Does your icemaker work? You've got your warranty papers?
Did they clean their hand prints off the cabinets, woodwork and trim? Did they sweep up and pick up the garbage reno creates?
Have you posted pictures of your kitchen on Gardenweb?

I've gotta stop. There was a lot more in my head than I'd expected.
What have you learned that you should have noticed?
What would you tell the next person who is ready to sign off?
