Good photos. Thanks. It looks to me like it is really a vertical gap
only -- meaning that the sidewalk dropped down over time and that caused the
gap.

Given what you wrote, if it were me I would just buy a small bag of
concrete, scrape out the old caulk, dig out a little behind the sidewalk
below the sidewalk surface level, mix up the concrete, and use it to fill in
the gap. When you smooth it off, trowel it so it forms a continuation
downward of the vertical front side of the concrete porch. And, if needed,
trowel along the surface of the sidewalk so the new concrete looks correct.
It should be pretty quick and easy to do.

You could also probably use mortar mix instead of concrete if you wanted to
do that. The gap size is such that either would probably work fine for what
you want to achieve. Look and see what they have at Home Depot or Lowes
etc. and pick one. You probably won't need much, and personally I don't
like lugging around big bags of concrete or mortar. So, even though it
would cost more, you could always buy a couple of small 10-pound bags of the
stuff. One bag may do it and you can return the second bag if it is
unopened and you don't need it.

I think any of the regular concrete or mortar mixes will fairly closely
match the color of what is there now. I would avoid any of those special
concrete crack repair mixes etc. because they are often a darker gray color
that won't look right, plus you don't need that.

Good luck.

Let us know how it turns out.

P.S. Since the job is so easy, I am with you and I would just skip even
contacting the condo association. I would just do the fix and forget about
it.

For gaps that size, especially in differing structures, mortar rarely
is the best choice. Something flexible, like caulk designed for concrete
is more likely to last.
