Planning Review/Site Plan Review

The initial review begins with the Planning Department. A Site Plan Review application is required when submitting your project for review.

The Planning Department will also determine if a project needs to go through entitlements (Special Use Permit, Design Review, Tentative Map, Lot Size Exception, etc.) and a public hearing before the Planning Commission prior to moving a project forward to Building & Safety.

Building Plan Check

A building plan check is conducted by an LA County Plan Check Engineer to ensure proposed designs comply with health and safety regulations.

After the initial plan check, comments are sent to the applicant. A re-check is usually required to ensure all comments have been addressed.

Generally, the applicant is instructed to submit to Building & Safety plan check once the Planning Department conditionally approves the plans.
