On Friday, the Oakland warehouse known as the 'Ghost Ship' caught fire, resulting in dozens of deaths.
Shortly after the blaze, building owner Derick Ion Almena took to Facebook, expressing angst over his personal loss, reports KTVU.
He wrote, "Confirmed. Everything I worked so hard for is gone. Blessed that my children and Micah were at a hotel safe and sound...It's as it I have woken from a dream filled with opulence and hope...to be standing now in poverty of self worth."

Almena's post drew immediate backlash.
The warehouse, which was the site of a party on the night of the tragedy, had for some time been used as both artist studios and illegal housing.
People familiar with the structure described the building as dangerous, saying it had insufficient exits and floors cluttered by wood stacks and loose electrical cords.
Danielle Boudreaux, the owner's former friend, noted, "If you were going there for a party, you wouldn't be aware of the maze that you have to go through to get out."
