Survivors of the Berkeley balcony collapse and bereaved family members are lobbying the California State Assembly for a change in the law.
In a moving testimony, Aoife Beary spoke of how her birthday will forever be linked with the deaths of six of her friends.
Six students died and seven suffered catastrophic injuries when the balcony they were on collapsed last summer.
It later emerged the builder of the Library Gardens apartment complex had paid over 26 million dollars in settlements relating to other cases of building defects.
Berkeley survivors want the law changed to require builders disclose details of such payouts.
Aoife's mother, Angela Beary said the injuries her daughter suffered are life-altering.
