This shall be done for each of the seismic design categories applicable to the state.(2) Subsequent to development of the building code provisions pursuant to paragraph (1), the working group shall direct the commission and the Department of Housing and Community Development to propose the appropriate building standards for consideration by the commission during the next regularly scheduled Triennial Adoption Cycle occurring after January 1, 2020.(c) If the mandatory building code provisions under subdivision (b) are not completed in time for inclusion with the California Building Standards Code, effective January 1, 2023, the commission and department shall produce a guidance document for use by architects, building owners, insurance companies, and local jurisdictions that would provide a higher level of structural strength in new construction with the goal of enabling functional recovery after a significant seismic event. The commission is authorized to take the steps necessary to produce and distribute this document to interested parties via its Internet Web site and other venues.(d) The commission and the department are authorized to adopt regulations based upon the recommendations resulting from the working group for nonresidential occupancies.

Engineered buildings do not include one-, two-, and three-story single family homes and buildings consisting of three or more townhouse units.(2)Immediate occupancy means a postearthquake damage state in which only very limited structural damage has occurred. The basic vertical- and lateral-force-resisting systems of the building retain almost all of their preearthquake strength and stiffness. The risk of life-threatening injury as a result of structural damage is very low, and although some minor structural repairs might be appropriate, these repairs would generally not be required before reoccupancy. Continued use of the building is not limited by its structural condition but might be limited by damage or disruption to nonstructural elements of the building, furnishings, or equipment and availability of external utility services.(3)Strength and stiffness requirement means the design of an ordinary building would be at least 50 percent stronger and stiffer than otherwise required.
