Santa Monica

Non-Ductile Concrete Structures

The city of Santa Monica developed a seismic retrofit plan following the 1994 Northridge earthquake. It was the first city in the Southern California region to establish aggressive non-ductile building regulations. However, many buildings within Santa Monica did not comply with this ordinance. Click here for information regarding the ordinance adopted in 1999.

The city of Santa Monica is currently updating its seismic ordinances to current standards. It is anticipated that updated ordinances will be before the Santa Monica City Council in late 2016.

Please note the following information is from the ordinance adopted by the city of Santa Monica in 1999.

 

1999 Ordinance Scope

Santa Monica’s 1999 non-ductile concrete ordinance applied to existing buildings that have the following characteristics:

  • Designed under the building code in effect prior to January 11, 1976 or built with permits issued before January 11, 1978
  • Concrete floors or roofs supported by reinforced concrete walls or frames and columns; concrete frames with masonry infill

1999 Ordinance Building Classifications

Santa Monica established building-type classifications to prioritize retrofit efforts in order of the apparent risk associated with damage to the structure based on occupant load. This classification (Type I, II, III, or IV) was determined by the Building Officer at the time of inspection. If a building falls within the scope of the ordinance, the building classification will be determined and a written notice to the owner will be provided. Upon receipt of this notice, general timelines are established for each building type.

Type I

Must be usable in the event of an emergency (e.g., hospitals, police
and fire stations, disaster recovery centers)

Type II

100+ occupants or occupied area other than parking or storage
on the first floor

Type III

20–99 occupants

Type IV

Fewer than 20 occupants
