There is no maintenance interval for the chain. Based on my TSX with a similar K24 engine, there is an access cover to look at the hydraulic tensioner. If the tensioner arm is past 13.5 mm, then replace the chain and guides. I would check the manual (see below).
I would recommend that you buy a pdf of the shop manual. I got one from automanualsource on Ebay for ~$20 for my TSX. It is worth the investment. It will pay for itself if you do one simple DIY on your Accord.
No, there ARE times when you should do the chain. Like PA says, you look at how far the tensioner is extended. It's not some automatic "every xxx miles", and it's sorta unusual for the chain to stretch during the normal life of a car. But if you drive tons of miles, or if you keep the car until the wheels fall off, you might eventually need to replace the chain & sprockets.

I'm a new guy here, so, if I post something "dumb" please tell me.
First-of all, my mechanic told me that, as a matter of course, I should change the timing chain. (He actually told me it was a timing BELT).
How true is that, in general ?
How certain can I be that I have a timing chain, and not a timing belt ?
I have 193,000 beautiful miles on my 2005 LX 4 door 4 cyl 5 speed man.
Second question is : how easy is it to locate and check the tensioner ?
Third question on the serpentine belt : Should I go with original honda, or, is a premium NAPA or AUTO Zone belt sufficient ?
Honda has a code for the chain being stretched beyond its serviceable life. P0341, when the chain stretches to that point the cam and crank sensors become out of phase. no choice at this point but to replace chain and tensioner. regular oil services with the recommended grade (i use synthetic) will give you at least 250k miles or more.
