We are a team of Accessory Dwelling Units (ADU) experts in Orange County, who help homeowners turn their ADU visions into reality. We prepare all the Architectural and Engineering Plans required to build an ADU. Our team submits the required plans to the City or County where the project is located and obtains plan approvals ready to issue permits to build.

We know all the ins and outs of ADU requirements, so you can trust us to get you the most bang for your buck. From drawing up plans to processing permits with the City, we’ll take care of it all.

Ehab, the mastermind behind EM SoCal, is a civil engineer, so you can bet he’s all about nailing the details. 

He’s on a mission to make sure everything’s on point and absolutely top-notch. When it comes to ADU projects, this dude’s the real MVP. And those nitpicky construction rules and ADU laws? Yeah, he’s got them down pat.

EM Socal Engineering’s clear and prompt communication was outstanding. I probably annoyed them with all my questions lol, but they answered each and every one .
