Late in 2016, the building's homeowner association hired firm Allana, Buick and Bers to investigate a unit owned by Paula Pretlow. Pretlow and several other residents complained in the past of "unexplained odors permeating their luxury units," NBC Bay Area reported.
The consultants discovered openings arounds pipes and ducts in the walls. Typically, gaps like these are sealed with fire-resistant caulking to make sure fires are contained where they start.
If a small fire was to break out in the unit below where Pretlow lives, the flames could more easily spread to her condo or cause smoke damage in the walls, according to NBC Bay Area.
The report only pertained to the unit owned by Pretlow, though others could be susceptible.
