A look at recent adu projects across Moreno Valley and surrounding areas.
ADUs Built with Care, Backed by Experience
We started building ADUs in the Inland Empire because we saw homeowners being underserved - handed generic plans, left to navigate city permits alone, and surprised by costs that ballooned past original quotes. We built this company to do things differently: with honesty, skilled hands, and a genuine investment in your outcome.
Every ADU we design and build reflects years of experience working with Moreno Valley's specific zoning rules, soil conditions, and utility infrastructure. That local knowledge means fewer surprises, smoother approvals, and a finished home you're proud to show off - whether you're housing family or generating rental income.
Meet Our Team
Full-Service ADU, One Trusted Team
Managing an ADU project means coordinating designers, engineers, permit runners, and multiple contractors - unless you work with us. We serve as your single point of contact from the first design conversation through final city sign-off, keeping communication clear and accountability undivided.
Our clients tell us the greatest gift we give them isn't just a beautiful ADU - it's a stress-free experience. We handle the complexity so you can focus on the exciting part: imagining how this new space will improve your property and your life.
See How It Works
What Homeowners Say
Projects across Moreno Valley and surrounding communities.
"Every allowance was itemised at the start, so the finish selections did not turn into a surprise at the end."
"Garage conversion finished on the drawings and close to the schedule. They were honest that the sewer connection was the unknown, and it was."
"The permit set and the build were one contract with one number. Our neighbours used two firms and spent a year watching them blame each other."
"The rental income has covered the payment since the second month. They were realistic about the numbers rather than optimistic."
"They walked us through setbacks and utility capacity before we paid anything, and told us one of our two options was not going to get approved."
Your ADU Journey, Made Simple
We've refined every stage of the ADU process so you always know what's happening, what's next, and who to call.
Free Consultation
We sit down with you - in person or virtually - to understand your goals, your property, and your budget. No pressure, just an honest conversation about what's possible.
Site Evaluation
Our team visits your Moreno Valley property to assess lot size, setbacks, utilities, and site conditions. This hands-on review ensures your ADU design is grounded in reality from day one.
Custom ADU Design
Our designers craft floor plans and elevations tailored to your lifestyle and property, balancing livability, curb appeal, and long-term value in every detail.
Permit Application & Approvals
We prepare and submit a complete permit package to the City of Moreno Valley on your behalf, managing plan check comments and corrections until approval is secured.
Site Prep & Utilities
Before construction begins, we coordinate grading, drainage, and utility connections - gas, water, sewer, and electrical - ensuring your build site is ready and code-compliant.
Construction & Framing
Our skilled craftsmen break ground and bring your plans to life, maintaining clean, organized job sites and delivering quality framing, insulation, and structural work on schedule.
Finishes & Interior Work
From flooring and cabinetry to fixtures and paint, we install every finish with the care and precision that makes a house feel like home - even in a compact ADU footprint.
Final Inspection & Handover
We walk every completed ADU through a thorough quality review before city final inspection, then hand you the keys with a full orientation and our satisfaction guarantee in hand.
What Sets Our ADUs Apart
Every project we deliver reflects our commitment to craftsmanship, transparency, and homes that genuinely improve people's lives.

Space Efficiency
Our designers maximize every square foot of your ADU, creating layouts that feel open, functional, and livable - no wasted space, no awkward transitions.
Craftsmanship Quality
We self-perform critical construction phases and vet every trade partner to ensure the same high standard of workmanship runs from foundation to finish.
Utility Integration
Proper utility planning from the start prevents expensive surprises mid-build - we engineer water, sewer, gas, and electrical connections for reliability and long-term performance.
Schedule Reliability
We build realistic timelines and hold ourselves accountable to them, communicating proactively so you're never left wondering about progress on your project.

Every ADU we build meets current California Title 24 energy standards, with options to upgrade insulation, windows, and systems for lower utility bills year after year.

ADU Service Across the Moreno Valley Area
We Are the Moreno Valley Team for Ellery.
Ellery was founded in 2015, the year California's ADU law changed and the permitting queue became the actual product. It is a design-build studio rather than a contractor: the drawings, the permit set and the build are one contract with one price, because the ADU projects that go wrong are almost always the ones where the designer and the builder can each blame the other.
Same training, same parts, same pricing practice, and the same 365-Day Done Right Promise - delivered by people who live here.
