After a major earthquake involving damage to Sunnyvale buildings, it is important that buildings are inspected promptly for their safety and structural integrity so that they can be reoccupied and business can resume operations as soon as it is safely possible. The Building Division and volunteer inspectors utilize standard emergency inspection and posting procedures with the overarching focus aimed at protecting the safety of our citizens and facilitating the City’s economic development objectives. Some building owners may wish to develop programs of private inspection for their buildings to permit rapid, individualized emergency response in the aftermath of a major earthquake in order to allow re-occupancy of the building sooner.

A program of private emergency building inspection, including precertification of building owners' engineers or architects, is outlined in the Building Occupancy Resumption Program document.
