Narrative:

Aircraft X had landed and rolled out rwy 8. The airline terminal at bur is very close to rwy 8 and does not meet current rsa (runway safety area) standards. An aircraft the size of a B737 such as aircraft X only has something like 6 inches of wingtip clearance from the runway edge lines when they are taxiing with their nosewheel established on the solid yellow line in the terminal taxi lane. I instructed aircraft X to turn right into the terminal and taxi to his gate; as is standard with airline arrivals at bur. As the next arrival (aircraft Y) was touching down on rwy 8; I noticed that aircraft X was taxiing with his nosewheel about 5 feet to the right of the terminal solid yellow line; meaning that his wings were likely encroaching on the edge of rwy 8. The angle from the tower makes it very difficult to visually determine if the wings are over the line; even when using binoculars. Additionally; the terminal is behind where local control usually stands so it is an often-neglected part of some peoples' scan. Aircraft that are instructed to turn into the terminal are often quickly forgotten about. I reached out for aircraft X but he was not on my frequency. Ground control reached out as well; but he was not on their frequency either. Since the taxi lane is a non-movement area; the aircraft was likely talking to its ground ops crew. By the time I noticed the problem with aircraft X; aircraft Y was already touching down and it was too late to send him around. The two aircraft never came very close; as aircraft Y stopped and exited the runway before reaching the terminal; but I do not know if an incursion occurred or not.bur's old terminal placement is well outside of modern safety standards. Other than building a new terminal that complies with current standards; the only thing we can do is to be very cognizant of the situation.
