Soft Story Program - Regulations for Potentially Hazardous Buildings Containing Soft, Weak or Open Front Stories

The City of Berkeley requires owners of owners of soft, weak or open front (SWOF) buildings with five or more dwelling units to retrofit their buildings per Berkeley Municipal Code Chapter 19.39. Owners have until December 31, 2016 to apply for a building permit and two years to complete the work after submitting their permit application. The law took effect January 4, 2014 and applies to wood frame buildings constructed prior to 1978.   

SWOF building owners must also post an earthquake warning sign and notify their tenants of the building's potentially hazardous condition. Under the first phase of the soft story program, starting in 2005, SWOF building owners were required to submit an engineering evaluation report identifying their building's weaknesses and ways to remedy those weaknesses.

A soft, weak or open front (SWOF) building is a wood-frame building with more than one story that typically has parking, a commercial storefront or other similar open floor spaces on the ground floor. This leads to a relatively soft or weak lateral load resisting system in the lower story and makes the building potentially hazardous in the event of an earthquake.
