Voluntary Residential Retrofit Information

Voluntary Retrofit of Older Residential Wood frame Structures: A program of the City’s Building and Safety Division that is designed to assist owners with the seismic upgrade of single family homes. The City of Ventura Building and Safety Division has developed a Voluntary Seismic Retrofit Program for Older Residential Structures to promote public safety and welfare by reducing the risk of earthquake-induced damage to existing homes. In the aftermath of a major seismic event, those who reside in homes rendered uninhabitable by damage incurred in the initial or subsequent events will find themselves without shelter.

The program has been designed to make a simple, effective and efficient way for our Ventura City residents to do the retrofit on their homes that are on “unbraced cripple walls” or that are not bolted to the foundation. A standard retrofit plan is available for free at the permit counter, located at 501 Poli Street Room 117. A single sheet plan consists of 1) Area to draw the outline of your home, 2) Instructions, 3) Technical Notes, 4) Construction Details, 5) Reinforcement Schedule. Residents pay a 1-hour inspectionpermit fee and plans will be reviewed over the counter and a permit can be issued the same day. Please see the links below for additional information.
