deck board overlap
I am installing a new deck surface and wonder about having the board ends overlap the rim joist. I have seen decks with anywhere from no overlap to up to 2" overlap.
Any comments would be appreciated.

I would cut them flush with the rim joist and then use a 1x3 or 1x4 to cover the cut ends. It makes for a cleaner look.
Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.
My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

It really depends on what you like. most often on pressure treated decks, we have a 1" or so overhang. Composite decking can be had with matching edge trim so you cut it flush then add the trim.
Structurally it doesn't make any difference which style you go with.

I do it with about a 1 inch overhang all the way around, not just the ends. It's kind of like the 'drip edge' of a countertop -- you don't want dripping water to damage what is below the top. Let the water drip to the ground. I recently did a repair for a guy on his deck where the Trex was not over hanging and the water was rotting the lumber below. But there is more than one way to do things.

I use about 1 to 1-1/2" on my decks. I usually don't try to cut them exact when installing but let them run wild. I later come back and measure uniformly on each end and snap a chaulk line. Then use a circular saw to cut them off. That way your overhang is consistant.
