Get More From the Property You Already Own
An ADU is one of the smartest ways to add value and flexibility to your home — a guest suite, a rental unit, a home office, or a private space for aging parents or grown kids. At EM Construction, we design and build accessory dwelling units and garage conversions for homeowners across Orange County, Riverside, and Los Angeles.
From the first conversation to the final walkthrough, you work directly with the family behind the company. We handle the whole process — feasibility, design, permitting, and construction — and build every unit fully permitted and to California code, so it adds real, lasting value to your property.

Frequently Asked Questions
ADU & Garage Conversion FAQs

Yes — ADUs require permits, and proper permitting is what makes your unit safe, legal, and a real addition to your property's value. We handle the permitting process for you.
Can I convert my garage into an ADU?
In many cases, yes — a garage conversion is often one of the most cost-effective ways to add a livable unit. We'll assess your garage and let you know what's possible during your free walk-through.
