Poor coverage at Everett, WA 45-80 building

The 45-80 building at 9801 27th Ave W, Everett, WA is poor.  Inside the building, according to the Network Cell Info app the signal strength is around -113 on band 71 and outside the building its not much better, at -105.   Moving 500 feet to the east across the parking lot, the signal improves considerably.   Are there adjustments that can be made to the nearby cell towers to improve the signal at the 45-80 building?
