What Our Customers Are Saying
"The rental income has covered the payment since the second month. They were realistic about the numbers rather than optimistic."
"Handled the whole planning process. We went to one hearing and that was it."
"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."
"Detached unit in the back garden. Good design, good build quality, and the cost changes were documented and agreed in advance."
"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."
"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."

ADU Service Across the Chino Hills Area
We Are the Chino Hills 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.
