Can someone point me in the right direction?

I know in Europe in apartment/condo stairwells it's very popular to have
timers on the lights so that they turn on when there is motion and turn
off after 10 or so minutes.

As I recently bought a condo in a small building, the rest of the owners
and I would like to reduce our condo fee costs by implementing timers in
the public stairwell.

They do exist, but you may not be allowed to use them. Local codes vary,
but many call for lighting all the time in common stairwells and hallways.
Change out the bulbs to compact fluorescent and you will save a lot of
energy for that type of application. Not to mention that they last a lot
longer so you don't have to change them.
