Not sure about NYC specific codes but in many places landmark status only protects the exterior.
In NYC, there are two types of landmark designation: exterior and interior. An interior designation is rarer and means you cannot make changes to the interior without specific approval. Most of the landmarked Broadway theaters are interior landmarks, though not all.
A few years ago I found a great site that explained the difference and listed all the interior landmarks, but I cannot find it right now.
