RE: "....bought a 27th-floor apartment in a high-rise overlooking Waikiki about 15 years ago, they didn’t realize the wave-shaped building had no fire sprinklers.'
One simple, cost free way to inform purchasers would be to make "sprinkler system" as part of the yes/no on the real estate disclosure form that is filled out prior to the sale of any condo or house. I do not recall seeing it on the form, maybe it is there already. If not, LEGISLATORS..... STEP UP and mandate it be added to the form.
