I have the feeling that adding a comma to this would be good.

FROM:
We'll be home by sunset barring accidents.
TO:
We'll be home by sunset, barring accidents.

Any opinions?

We'll be home by sunset barring any accidents.
OR
Barring any accidents, we'll be home by sunset.

"Barring accidents" is acceptable.

What I was wondering about is whether a comma should be inserted.

Of course, "barring any accidents' is OK, too.

I didn't say it was unacceptable.

So, since you didn't put the comma before "barring any accidents," that means I don't need to insert a comma in this sentence?

I'm not saying you "need" to do anything.

What I am saying is that:

1) I don't think it needs a comma, but
2) I think ending the sentence with "barring accidents" reads more naturally and easily with "any" inserted between the two words.

Anywhere else in the sentence, I *would* put a comma before/after "barring accidents".

You asked. That's just what I'd do.
