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. The City of Los Angeles' LID Ordinance went into effect in May 2012 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 an application has been submitted, the status of request can be reviewed online anytime.

For general LID information or to download plan check documents, please visit lacitysan.org/LID. Questions may be directed to the LID Public Counter general email at san.swplancheck@lacity.org
