About Millan Construction, Inc

Professional ADU Construction Services in San Diego

The Millan Construction specializes in building Accessory Dwelling Units (ADUs) in San Diego that are beautiful, functional, and fully compliant with California's housing regulations. Whether a homeowner is looking to add a rental unit, a home office, or a space for family members, this experienced ADU builder guides clients every step of the way — from initial design through to final inspection.

With rising housing demand across the region, many San Diego homeowners are turning to ADUs as smart, flexible solutions. Not only do ADUs increase a property's overall value, they also open doors to passive income through long-term or short-term rentals. San Diego's ADU-friendly regulations make it easier than ever to build an additional unit on an existing property.

What Is an Accessory Dwelling Unit?

An accessory dwelling unit is a self-contained living space that shares a lot with a primary residence. It includes all the essential features of a home — a kitchen, bathroom, living area, and a separate entrance. ADUs can be detached or attached to the main home, making them ideal for aging parents, college students, or rental tenants. As a trusted detached ADU builder and granny flat builder, The Millan Construction brings expertise and craftsmanship to every project.

  3. Full Construction: From laying the foundation to final paint and finishes, their skilled ADU contractors handle every construction detail — on time and within budget.

Millan Construction, Inc Reviews

Build Your Beautiful Self

"I have been using the team with Millan Construction for a couple of years now for my clients and my own projects. I can't express enough how happy I am with their service and work quality. They make sure to get my projects completed on time and have even repaired work that was done by another contractor incorrectly. Every job site of theirs I have ever visited, has always had multiple trades working at the same time which for someone who is on a timeline with a project, makes a huge difference. They have even helped me out with last minute fixes on a client's house so we could close in time after the seller's contractors cancelled. If you want a company that you can rely on to do your renovation projects, or just do some quick repairs, you will be in great hands with Millan. If you need more of a referral, call me. I will tell you all about it!"

"I had the honor of working with Jorge Millian and witnessing his incredible transformation of a home with significant deferred maintenance into a stunning showcase of quality and craftsmanship. Jorge renovated the entire home from top to bottom creating an open-concept floor plan, expanding the bathrooms with custom tile work, installing beautiful cabinetry, and adding countless elegant touches throughout. His attention to detail, professionalism, and commitment to excellence truly set him apart. I highly recommend Jorge Millian Construction to anyone looking for a contractor who delivers exceptional results."

"I recently had several projects completed with Millan Construction including a full kitchen remodel, a master bathroom, bedroom and closet remodel and a few other home improvement projects around the house. I highly recommend them for any remodeling and home improvement jobs! When you let someone into your home, especially for as long as we did with all our projects, you have to trust them and have great communication. Millan Construction was responsive in communication, helpful, friendly and trustworthy. The workers did an amazing job and always made sure everything was done well. If there was ever an issue, they ensured things were taken care of in a timely manner. Having Ashley as a project manager was so helpful in making sure we had a consistent person to direct questions to. We will absolutely be using Millan Construction for our next home project! :"
