Following the collapse of the balcony in Berkeley, that killed 6 and seriously injured 7 others, the California Building Safety Commission adopted me regulations on building and waterproofing Elevated Exterior Elements EEE for short.

The adoption of these emergency regulations will increase balcony safety standards by increasing load design, using decay resistant wood and Inspections of waterproofing before covering with other materials, such as a concrete overburden.

Testimony from the Irish families and victims has helped cause these changes. Jackie Donohue, mother of one child killed in the collapse has been leading the charge in bringing changes to  balcony construction along with requiring inspections.

After Berkeley adopted ordinates requiring inspections, over 800 balconies in that city alone have been found to be deficient.
