Navigating the Plan Check Procedure in the City of Los Angeles (Residential and/or Commercial)

Embarking on a construction project in the City of Los Angeles can be an exciting endeavor. However, it’s crucial to understand and navigate the plan check procedure to ensure a smooth approval process. Let’s explore the plan check procedure in the City of Los Angeles, highlighting its key components, guidelines, and estimated timelines.


  1. Preparing the Application: Before submitting plans for review, gather all required documents, including application forms, building plans, engineering calculations, existing city records and supporting materials. Ensure compliance with the City’s specific requirements and regulations. Timeline: Allow 2-4 weeks for thorough preparation.
  2. Submitting the Application: Submit the application and plans electronically through the Los Angeles Department of Building and Safety (LADBS) online portal. Or you may submit in person, which sometimes can be faster than submitting online. This procedure and timeline is subject to change. Pay the necessary fees based on the project’s size, type, and complexity. Timeline: Once the application is complete, submission can typically be done within a few days.
  3. Preliminary Review: During the preliminary review stage, the LADBS assesses the application for completeness and adherence to building codes and zoning regulations. They may request additional information or corrections before proceeding to the formal plan check. Timeline: The preliminary review process can take 1-2 weeks. If you are at the counter submitting in person, you may get plan check that day or approval to submit.
  4. Plan Check Process: The plan check process involves a thorough review of the submitted plans by LADBS plan check engineers. They evaluate the compliance of the proposed construction with building codes, fire safety standards, structural integrity, accessibility, parking, and other relevant regulations. Note: building, mechanical, electrical and plumbing are all separate plan reviews and/or permits. Timeline: The plan check process can take 4-8 weeks, depending on the complexity of the project.
  5. Corrections and Revisions: After the initial review, the LADBS provides feedback, which may include required corrections, revisions and an Agency Clearance Sheet. The applicant must address these comments and resubmit revised plans for further review, and contact each Agency that is listed as a required clearance, find out what they need, provide it and then once they approve, they will Clear the project in the system. Timeline: The applicant typically has 1-2 weeks to make the necessary corrections, get the Clearances and resubmit the revised plans.
  6. Permit Issuance: Once the plans meet all requirements, receive final approval and the permit fees are paid, the LADBS issues the necessary construction permits. The applicant can then proceed with the construction phase of the project. Timeline: Permit issuance usually takes no more than 1 week after the final approval.

Note: the timelines noted above are average for projects, in the case of special Planning Dept projects, the times for the Clearances can take longer. An example of this would be if a Conditional Use Permit (CUP) is required for some reason—that alone can run 3-9 months.


Key Guidelines to Facilitate the Plan Check Procedure:

  1. Thoroughness and Accuracy: Ensure all required documents are complete, accurate, and in compliance with the City’s guidelines. This minimizes the chances of additional requests for information and revisions.
  2. Adherence to Building Codes: Familiarize yourself with the applicable building codes, fire safety standards, and zoning regulations in the City of Los Angeles. Design and prepare plans accordingly to avoid unnecessary delays.
  3. Professional Assistance: Engage experienced architects, engineers, permit expediters and consultants who are well-versed in the City’s regulations and can help navigate the plan check process smoothly.
  4. Communication and Timeliness: Promptly respond to any requests for additional information or corrections from the LADBS. Timely communication and adherence to deadlines ensure efficient processing of the application.


Conclusion: Understanding and following the plan check procedure in the City of Los Angeles is vital for a successful construction project. By preparing a comprehensive application, adhering to building codes, addressing feedback promptly, and seeking professional assistance when needed, applicants can navigate the process smoothly.
