If you are delivering your work to a mastering studio, they usually ask
for a bit of headroom so that they can add compression and limiting
using their specialized equipment, ears and monitors. This can vary
according to genre of music and mastering studio.
A mastering studio in New York that was mixing a punk album asked that
they have peaks no higher than -3db.
