The City of Los Angeles requires mandatory seismic retrofitting for soft-story buildings under City Ordinance 183893 and 184081.

Per the LA Department of Building & Safety Website:
“The goal of the mandatory retrofit program, under Ordinance 183893 and Ordinance 184081, is to reduce structural deficiencies by the most economical and feasible method. Without proper strengthening, these vulnerable buildings may be subjected to structural failure during and/or after an earthquake.”


All Orders to Comply have been distributed by the Los Angeles Department of Building and Safety. If you are a recipient, TSA can provide a cost effective, time efficient plan of action to attain the Certificate of Compliance.
