What is the process to obtain a Los Angeles City Research Report for my product?

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.

  • I have a Los Angeles City Research Report (LARR). How do I know if my approval is applicable to the current code?

    The LARR may be used only for projects permitted under the Code version specified on the LARR. To update the LARR to the Current LABC, when there are no changes to the existing products nor to any code requirements regarding your product, you may file an Application for Renewal/Clerical Modification. For Product Approvals that expire within 12 months, submit the fee for a Renewal and the approval will be updated during as it is renewed. For Products that do not expire within 12 months of the time of application, pay the clerical modification fee and check the respective box.

    For LARRs based on a Model Code Agency Evaluation Report: 

    The LARR cannot be updated unless the Evaluation Report specifies the corresponding Code Edition; ensure the Evaluation Report is Updated before filing to update your LARR. If additional products are added to the approval, or changes to the existing products have been made, or if additional testing or analysis is required due to code changes, you must file an Application for Technical Modification. A separate Renewal Application will need to be submitted if the LARR is scheduled to expire soon.

    How long does it take to obtain a Los Angeles City Research Report? Can the process be expedited?

    Our goal is to assign an application in approximately 5 weeks to one of our engineers and an additional 3-7 weeks (depending on the complexity of the submittal) for the evaluation to be completed, a draft copy of the research report to be written, and the final copy of the research report signed. If the substantiating data is incomplete, such as missing test reports, testing not conducted by an approved testing agency, incomplete or missing engineering calculations, etc., the time to obtain a Los Angeles City Research Report may take longer. 

    Expedite report review is available pursuant to section 98.0422 of the Los Angeles City Municipal Code. The amount of the fee for this service is in addition to the normal review fee and is equal to one-half of the review fee.

    The intent of the expedite service is to reduce the time to assign your application from approximately 5-weeks to 2- weeks. 

    For an estimate of the current assignment time for the expediting service you may call the Building Research Section at (213) 202-9812.

    Los Angeles City Research Reports are allowed to be based on an Evaluation Report from a Nationally Recognized Model Code Agency. Who are Nationally Recognized Model Code Agencies currently accepted by LADBS Building Research Section?

    Section III of Alternate Building Materials Products Approval Requirements specifies the qualifications that Nationally Recognized Model Code Agency must meet for their Evaluation Report to be used as a basis for a Los Angeles City Research Report.

    Currently, Evaluation Reports from the International Code Council Evaluation Services (ICC-ES) and, the International Association of Plumbing and Mechanical Officials Uniform Evaluation Service (IAPMO UES) may be used as a basis for a Los Angeles City Research Report.
