Welcome to the Low Impact Development (LID) Plan Check Submittal portal

LID is a leading stormwater management strategy that seeks to mitigate the impacts of runoff and stormwater pollution as close to its source as possible. In November 2011, the City of Los Angeles adopted the Stormwater LID Ordinance (Original Ordinance #181899, updated September 2015-Ordinance #183833, and updated April 2024-Ordinance #188125) to support this effort.

New development and redevelopment projects are required to incorporate LID measures into their design plans as part of their plan check review and building permit approval process. Please use the LID Portal to start your LID Counter request for plan check and other building permit related items

To begin the process, please select an option from the Applications drop down menu atop this page. Once the application has been submitted, please join the Virtual Counter System Queue to speak to our counter staff and have your submitted documents reviewed. To access the LID Virtual Counter Queue, please go to appointments.lacity.org

LID Ordinance Revision Effective April 2nd, 2024: Ordinance No. 188125

Building or grading permits that have a LADBS Payment Date of April 2nd, 2024 or after, are subject to the LID Ordinance Revision. Any building or grading permits that have a Payment Date before April 2nd, 2024 are subject to the LID Ordinance that existed on the respective Payment Date.

Procedurally, LADBS staff will review and issue the LID Clearance to building and grading permits based on the Payment Date. Any building or grading permits that have a Payment Date before April 2nd, 2024 will have the LID Clearance added for work that proposes to add, create or replace 500 SF or more ofimpervious area. Building or grading permits that have a LADBS Payment Date of April 2nd, 2024 or after, will have the LID Clearance added for work that proposes to add, create or replace 2,500 SF or more ofimpervious area. Supplemental permits submitted after April 2nd, 2024 will be subject to the LID Ordinance that the original permit was subject to.

For permits subject to the LID Ordinance Revision, please note that LID Requirements will be applicable to the projects listed below. If your project does not meet the criteria below, but the LID Clearance was added to your permit, a formal submittal to LID will be required so that we may review your plans and clear your LID Clearance as “Not Required” if applicable.
