Stop us if you've heard this one before, but there are more problems at the Board of Equalization building downtown.

It's now estimated that getting all the paperwork in order to make repairs at 450 N Street will take two years, and that the actual renovations could last another three.

Video and lab work has now confirmed pipe corrosion on three floors actually runs all 24 stories, and that's in addition to the falling windows and mold problems previously reported.

"Quite frankly, even though my lawyers told me not to say this, I don't think it's safe," Board of Equalization Chairman Jerome Horton said. 

$60 million has been spent on repairs so far and $115 million would be needed to make changes and temporarily relocate employees.

Lawmakers are also considering a bill that would just move them into a new, permanent home.
