Detached ADU Construction in Hawthorne, CA

We build detached ADUs on your property, managing the project from planning and permitting through construction and final inspection.

Building a Detached ADU You'll Be Proud Of

A detached accessory dwelling unit is one of the smartest ways to add living space, rental income, or room for family on your property. At Jupiter Builders & Roofing, we handle Detached ADU Construction in Hawthorne, CA from the first conversation through final inspection, so you always know what's happening and why. We're a local company, we build to exacting standards, and we stand behind the work long after the project wraps up.

Why choose Jupiter Builders & Roofing

  • Service after the sale. You've probably heard the horror stories about contractors who cash the check and disappear. That's not us. We're not perfect, but if something needs attention after your ADU is finished, we'll be there to make it right.
  • We're local. Our company was born here and we're raising our family here. When you hire a contractor who lives in the community, you get someone who's easy to reach and genuinely accountable to the people they build for.
  • We keep you informed. From the start, we explain every part of the plan in plain language, answer your questions promptly, and give you clear ways to reach us whenever you need to. No guessing, no surprises.
  • We plan around your life. A detached ADU is a real construction project on your property, and we coordinate materials and scheduling to keep disruption to your daily routine as low as possible.

Our Detached ADU Construction process

We focus on complete, well-managed builds rather than quick fixes, and that shows in how we run each project. Here's what working with us typically looks like:

  1. In-person consultation and site review. We come out and look at your property in person to understand your lot, your goals, and what's realistically possible. This is how we build an accurate plan instead of a rushed guess.
  2. Design and planning. We help you shape a detached ADU that fits your space, your budget, and how you intend to use it, whether that's a rental, a home office, or a place for family to live comfortably.
  3. Permitting. We manage the permitting process so your project meets local requirements. This is one of the most frustrating parts of any build when you go it alone, and it's a part we carry for you.
  4. Written proposal. Before any work begins, you receive a clear written proposal that lays out the scope and your options, so you can approve everything with confidence.
  5. Construction. Our crew builds your detached ADU to high standards, coordinating materials and scheduling to keep the project moving while respecting your household's routine.
  6. Final inspection and walkthrough. We see the project through final inspection and walk the finished space with you, so you know everything meets the standard you were promised.

Because we specialize in complete new construction rather than piecemeal work, every phase is managed by a team that understands how the whole project fits together. That continuity means fewer gaps, fewer handoffs, and fewer of the miscommunications that slow projects down.

What a detached ADU can do for your property

A well-built detached unit gives you flexibility most homes don't have. Some homeowners want rental income in a market where space is at a premium. Others want a private place for aging parents or grown kids, or a quiet workspace separate from the main house. Whatever your reason, a detached ADU adds usable square footage and can meaningfully increase the value and function of your property. Our job is to build it right the first time, with quality that holds up for years, so you get the full benefit the investment was meant to deliver.

What is a detached ADU, and can you build one on my property?

A detached ADU is a separate, standalone living unit built on the same lot as your main home, with its own entrance and living space. We design and build detached ADUs across Los Angeles and Orange County, handling everything from the initial plan through to the final inspection. Call us at (310) 954-2008 for a free estimate.

Do you handle the permits and planning for a detached ADU?

Yes. We manage the full process for you, including planning and permitting, so you don't have to coordinate it all yourself. We'll explain each step up front and keep you informed as the project moves forward from paperwork through construction.

Will you inspect my property before giving me a price?

Always. We come out in person to look at your lot, layout and site conditions before quoting anything. After that visit, we prepare a written proposal laying out your options so you can review everything before approving the work.

Do you only build new ADUs, or can you also remodel my existing space?

We focus on new detached ADU construction and complete roof replacements. We don't take on general home remodeling, handyman work or minor repairs, so our attention stays on building your new unit to a high standard from the ground up.

How do you keep me informed during the ADU build?

We walk you through every part of the project and answer your questions in a timely way. You'll get clear ways to reach us whenever you need to, and because we're local and believe in service after the sale, we stay available if anything needs attention. Call (310) 954-2008 and we look forward to hearing from you.

    Great company to work with, after much debate and negotiations with a few other competitors i landed on jupiter. The process and communication were extremely better then previous contractors i have used in the past and will look to them on future home renovations. Masud was my point of contact and returned all my phone calls and answered late at night sometimes for some follow up questions. I was on a strict deadline for a graduation party to be held here and they actually finished a day ahead of schedule. Great team to work with.

    Jupiter Roofing did an amazing job on rebooting my house. We had an artificial slate installed on our roof and they had the expertise in doing the job right. Their detail, efficiency and easy communication with the staff was truly outstanding! I have many times since they have finished, the job recommended Jupiter Roofing to others looking to have their roof redone. I highly highly recommend them! Jason bahret.
