(WJE). This page serves as a knowledge base for information regarding seismic assessment and retrofit requirements and relevant deadlines that pertain to seismic ordinances in various cities throughoutCalifornia. It's intended for use by individuals andbuilding owners seeking an introduction to seismic ordinances.The information provided on SeismicOrdinances.com is general in nature and is subject to change as local authorities amend their current ordinances and adopt new ordinances. Thoserequiring specific information on seismic ordinances should contact their municipality.What is a seismic ordinance?A seismic ordinance is a law passed by local authorities requiring the evaluation and retrofit of specific building types proven to be vulnerable to seismic events. These ordinances were created in response to poor performance of certain classes of structuresduring previous earthquakes, such as the 1989 Loma Prieta earthquakeand the 1994 Northridge earthquake. These ordinances outline minimum requirements for mandatory evaluation and structural improvements intended to reduce earthquake-induced damage to classes of buildings identified to be particularly vulnerable to earthquake damage. These ordinances are generally not intended to strengthen buildings to a level of seismic performance equivalent to that of a new building designed using current building code requirements. Rather, these requirements address critical safety concerns by increasing the likelihood that occupantsare able to safely exit the building in the event of an earthquake.Is yourbuilding type included?The new generation of seismic ordinances iscategorized by one of two building types: (1) Wood-Frame Soft-Story Structures and (2) Non-Ductile Concrete Structures. Most of these newer ordinances apply to structures permitted for construction before January 1, 1978, although the specific cutoff date varies by municipality.Follow the links on this page for more information oneach building type and the associated ordinance(s).In California, there are also other types of mandatory seismic ordinances thatapplyto structure types such as unreinforced masonry (URM) buildings. The California URM Law was passed in 1986 and required local governments in high seismic zones to develop an inventory for URM buildings and establish a loss-reduction program. For a handful of California cities, ordinances requiring seismic retrofit were passed—but in the majority of cities, the local ordinances only required that owners identify buildings as being vulnerable. Typically, mandatory compliance dates for URM buildings in California covered by thisolder generation of seismic ordinances have passed, meaning that most of the buildings in California covered by these older ordinances should be in compliance.Because of this, SeismicOrdinances.com does not address URM ordinances in California. Those requiring specific information on URM ordinances in California should contact their municipality directly.Don’tSeeYourCity?Please note that SeismicOrdinances.com may not include all cities within California that have seismic ordinances in effect. Contact your local government officials for more information on future seismic ordinances, earthquake preparedness, and voluntary retrofits.Interested in seeking seismic consultation for your building?Wiss, Janney, Elstner Associates is a global firm of engineers, architects, and materials scientists committed to helping clients solve, repair, and avoid problems in the built world.
