Prior to 1980, building codes did not require builders to secure houses to their foundations. This does not mean that every house built before 1980 is “unsecured”, only that it was not a requirement. If your home is not properly secured, it may be at increased risk of “slipping” off the foundation during an earthquake. Retrofitting involves bolting your home to its foundation and providing sheer/pony wall strength.
