(1) Honors' Hall: Hall belonging to the Honors students
(2) Honors Hall: Hall associated with honors.
 
(1) _honors'_ is a noun m marked for plural & possessive that modifies
'hall' -- an adjectival (somethine that functions like an adjective)
rather than an adjective.
 
(2) _honors_ is a plural noun modifying 'hall' -- another adjectival.
 
Given that the word _honors_ is really common as a plural, I think it
would be fine to use it that way, without the apostrophe. I think it would
be less confusing to people, and you would be much less likely to have
misspellings of the title when people write about it. So although either
is grammatical, and (1) may be closer to your intended meaning, (2) is
both grammatical and will be less troublesome for others.
 
Apostrophe use is, as we all know, an area of great confusion, with good
reason. I see confusion in newspapers all the time when ambiguities show
up. Is it _teachers union_ or _teachers' union_? My sense of the meaning
calls for the second, but I seldom see it that way. In fact, informally
speaking, I detect a trend away from the use of apostrophes in such
constructions. I don't know if there is anything anyone can do about it,
if authorities at the level of LA Times copy editors are leaving off the
apostrophes.
