Introduction

An MEP permit allows you to undertake any new Mechanical, Electrical, and Plumbing project. However, each of these components requires a separate permit. For instance, a mechanical permit allows the installation of equipment like kitchen hood systems or HVAC systems. While a plumbing permit authorizes the installation of sprinklers, refrigeration, and gas lines. Moreover, you can get these permits separately or as part of the construction permit.

That aside, if you’re planning to undertake an MEP project in Los Angeles County, an MEP permit is required. More importantly, this applies to industrial, commercial, and multi-family residential buildings.

So, how do you obtain an MEP permit for an MEP design for industrial buildings? Or even commercial and residential projects? And how long will it take? If those are some of the questions in your mind, you’re in the right place. In this article, we’ll take you through some LA County plan submittal requirements for MEP projects!

LA County Permit Submissions

Every MEP project in LA County should be submitted online via EPIC-LA. EPIC-LA stands for the Electronic Permitting & Inspections for Los Angeles County. In essence, it’s an online portal that offers safety and building permitting services. At the same time, it allows you to track and view the process of your permits and plans.

Moreover, you can submit specifications, plans, and supporting documentation for approval. Not to forget that you can apply for an MEP permit for residential buildings and even pay permit fees on the site. However, before you submit the project, make sure you consult the local jurisdiction. This will help you know whether the local planning department requires a separate planning submission.

After submitting your project, it will undergo a screening process. And a notification indicating the fee will be sent through EPIC-LA. In most cases, checking the first building plan can take around 6 to 8 weeks. But, checking the MEP design for multi-family residential buildings may take 4 to 5 weeks. At the same time, this duration may vary depending on the complexity of your project. Other factors like how fast you respond and the number of corrections needed will also influence this duration.
