The evaluation time frame is based on the complexity of the product. Contact the Engineering Research Section for the current status. The process to obtain a Los Angeles City Research Report consists of the following steps:

1. Determine if a LARR is required or not using the Information Bulletin P/BC 2020-119.
2. Submit the following information to the Los Angeles City Department of Building and Safety Engineering Research Section: product literature describing how your product is to be used, substantiating data (i.e. test reports by approved 3rd party testing agency, engineering analysis), a completed application form for new LARR, along with a check in U.S. dollars drawn on a U.S. bank.
3. Once this information is received, your application package will be reviewed for completeness. If any deficiencies are determined, a letter will be sent to the applicant stating the deficiencies requiring correction or completeness.
4. After determining the application package is complete, the application will be logged in and assigned a log number and placed in line for review.
5. The substantiating data submitted will be evaluated to determine if it is at least the equivalent of the prescribed devise, material, or method of construction specified by the Los Angeles City Building Code in terms of quality, effective time period of fire resistance, strength, effectiveness, durability, and safety.
6. After reviewing the substantiating data, the research engineer assigned to the application will write a letter stating their comments and the information needed to complete the evaluation and/or correct the evaluation, if necessary.
7. Upon resolution of all comments a draft copy of the Los Angeles City Research Report will be written. The draft copy of the Research Report will be e-mailed to the applicant for their review and comment. In addition, a supplemental fee will be sent to the applicant to bill the additional reviewing hours for the report approval beyond the first 6 hours.
8. After all comments from the applicant have been resolved and the supplemental fee has been paid by the applicant, the Research Report will be submitted to the Chief of the Engineering Research Section for final review and approval. A signed copy of the Los Angeles City Research Report will be mailed to the applicant and a copy will be posted on the LADBS web site.
