Apartment building balconies in Berkeley, Calif., will be subject to inspections every three years under new regulations adopted following a deadly collapse.
The city council also adopted a measure to require new balconies to be made of corrosion-resistant material and be ventilated to prevent a buildup of moisture.
Six students were killed and seven others were hospitalized when the apartment balcony collapsed during a birthday party in June.
Inspectors said the balcony was supported by wooden beams that rotted from water damage. Prosecutors have opened a criminal investigation into the collapse.
