I live in a duplex and the bathroom/shower does NOT
have ANY vent for the steam to outside.

Shouldn't ALL bathrooms be vented in some manner?

I'm not a construction expert so wanted to ask abt it
here.

Should they all? Yes. Do they all? No. Code requires either a
window or a vent fan if there's no window. The vent fans take away a
lot of the moisture and a lot of the heat - it's a tradeoff on that
front. Moisture condensing inside your walls is an _excellent_ way to
promote rot and mold growth.

OK

Well this apartment I live in has a full bath and
shower...with no window and no vent of any kind!

Pretty dumb huh?

I understand that heat can be drawn out when a vent fan
is running but that would be preferable to mold growing
all over the place.

Anything I can do abt this not being up to code?

If it has a HVAC duct in there it should keep it aired out.
Unless you are just looking for trouble because you are mad at the
landlord? Most people don't open the window if they have one and
from my experience, most don't use the fan very often either.

Unless the bathroom was built or totally remodeled very recently -
requiring it to be up to code - no.

There are three things that support mold growth: spores, moisture and
the correct temperature range. You can't do anything about the last
two, so it's up to you to make sure that spores aren't given the chance
to grow. Basically this would require wiping down the entire bathroom
with a mile detergent solution periodically. If mold has taken hold, a
diluted chlorine bleach solution or TSP in hot water would be
necessary.

If it's any consolation, there are plenty of bathrooms with windows and
vent fans that still have mold growth. Regular maintanence is a must.
