When is a Permit Required?
A Building Permit is required to strengthen an existing building's resiliency to earthquake damage and collapse.
Buildings containing soft stories with 5 or more units, built before 1991, with two stories or more, and constructed with wood may be subject to a mandatory seismic retrofit (click here for a list of potentially subject buildings). For further info, please visit our Mandatory Soft Story Retrofit Program or refer to Oakland's Municipal Code Chapter 15.27 and Section 17.102.250.
Who Can Be Issued a Permit?
1. Contractors who are licensed by the State of California with a classification appropriate for the work that will be performed and have a current Business Tax Certificate.
2. Owners of a building or their legal representative.
