Understanding Los Angeles Research Reports (LARR) and Building Code Compliance

Navigating the building codes and material approvals in Los Angeles can be complex. A key component of this process is the Los Angeles Research Report (LARR), which validates the products permitted for use within the city. This article explains what a LARR is, its importance, and how it relates to the current Los Angeles City Building Code (LABC).

What is a Los Angeles Research Report (LARR)?

A Los Angeles Research Report (LARR) is an approval issued by the Los Angeles Department of Building and Safety (LADBS) that validates which products can be used, and for what purposes, within the city of Los Angeles [1]. It acts as a specific validation, similar to an ICC report, but is exclusively for use within the city limits. Product suppliers must obtain a LARR to have their products approved for use in Los Angeles construction projects [1].

LARR and the Los Angeles City Building Code (LABC)

The question of whether a LARR remains valid with updates to the Los Angeles City Building Code (LABC) is crucial. Your product approval is valid only for the Code version listed on both the Evaluation Report and the LARR approval letter. If either document doesn’t list the current version of the Building Code, an update is necessary [2].

Any revisions to the report must be submitted to the LADBS for review, along with the appropriate fee, to maintain the approval [2].

How to Search for LADBS Research Reports

You can search and review LADBS Research Reports for approved building, electrical, and mechanical products through the LADBS website [3]. Reports are categorized by manufacturer, products, and report number [3].
