Seismic Retrofit Program

Earthquake preparedness is a part of life for Southern Californians. Damage to vulnerable buildings, physical injury, and even death are the most apparent threats from earthquakes. There can also be significant economic damage in their aftermath.

Recent earthquakes have shown that some older buildings may be at risk during future earthquakes because of construction standards at the time they were built. Strengthening our buildings by retrofitting is the best way to save lives and infrastructure during an earthquake.

On February 14, 2017, City Council will be asked to modify existing law to make strengthening of five types of vulnerable buildings mandatory for property owners.

Compliance Time Frame

The following table shows the five types of buildings and compliance time frames. These buildings exhibit characteristics that make them less resilient to earthquakes. Please note that compliance dates will be calculated from the date the owner receives notice from the Building Officer. See the proposed schedule for notifying owners.

Potentially Seismically Vulnerable Buildings Type Structural Evaluation Report Due Retrofit Must be Completed Within
Unreinforced Masonry Buildings 3 Months 2 Years
Concrete Tilt-Up Building 4 Months 3 Years
Soft-Story Buildings 2 Years 6 Years
Non-Ductile Concrete Buildings 3 Years 10 Years
Steel Moment Frame Buildings 3 Years 20 Years
Single Family Voluntary

Potentially Vulnerable Buildings in Santa Monica

The following is a list of buildings identified by building permit records and/or visual identification as buildings that may require strengthening to increase safety during an earthquake.

Inclusion of a building on this list is not confirmation that the building is structurally deficient, hazardous or unsafe.

These buildings display characteristics such as age, appearance, construction material, method of design and construction, and structural records that may indicate a need for strengthening in preparation for an earthquake.

Buildings appearing on this list will receive notice from the City of Santa Monica to complete a structural analysis. Buildings found to be non-compliant with established standards for earthquake resistance will be ordered to strengthen the building through a seismic retrofit.

Update (January 31, 2017)

An additional 215 addresses of Soft-Story building type were added. The addition rectifies a database accounting issue.
