For the purposes of applying the 16 feet maximum height standard as required by state law (referenced in LAMC Section 12.22 A.33(c)(1)(iii), (g)(1), and GC Section 65852.2(e)(1)(D)), height shall be measured according to the standard Zoning Code definition of Height of Building or Structure in LAMC Section 12.03.

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.
