EXHIBITS ADMITTED INTO EVIDENCE: Arizona Registrar of Contractors Notice of Hearing Packet (“Packet”). Arizona Registrar of Contractors Exhibits 1-2. Respondent Exhibit A-B.
FINDINGS OF FACT
Redrock Constructions, LLC (“Respondent”) is the holder of License No. ROC 347183 issued by the Arizona Registrar of Contractors (“Registrar”).
On or about October 25, 2024, Ruben Dominguez (“Complainant”) entered into a contract with Coli Studio, Incorporated for, among other things, a 704 square foot Accessory Dwelling Unit (“ADU”). The contract was signed by Coli Studio representative Nicol Cardozo.
Complainant and his spouse, Diana Dominguez, found Coli Studio through the internet around June 2024. Coli Studio employees, Yessica and Erika, came out to Complainant’s house located in Phoenix, Arizona, for an initial visit. In July 2024, Yessica and Erika, came back out to Complainant’s house to discuss the project. Around August/September 2024, Pedro (Erika’s brother-in-law) and another Coli Studio employee came back out to Complainant’s property to discuss the project.
On August 19, 2024, Coli Studio was added to Respondent’s license as a parent entity, in a deal for Dimitri Gilles, Respondent Qualifying Party, to be a 25% stockholder in Coli Studio. The intention was to work as partners in building ADUs.
In October 2024, Complainant and Mrs. Dominguez went to the Coli Studio offices located on 200 E. Van Buren Street in Phoenix. Complainant and Mrs. Dominguez met the Chief Executive Officer, Romero Guzman, saw Erika & Yessica, and signed off on the contract. The contract was in the total amount of $155,000.00 and Complainant paid $124,000.00. At the top of the contract pages, displayed was License No. ROC 347183, Respondent’s ROC License number.
Around the same time, on October 15, 2024, Coli Studio added Mr. Gilles as a shareholder with the Arizona Corporation Commission.
On October 24, 2024, Complainant issued a Cashier’s Check payable to Coli Studio in the amount of $77,500.00, accepted and signed by Yessica.
On or about November 27, 2024, Mr. Gilles spoke with the Registrar about removing Coli Studio from Respondent’s license. Mr. Gilles was not receiving communications from Coli Studio and no longer wanted to partner with them. On the Registrar’s portal, the disassociation went through and was effective November 27, 2024.
There was no activity on Complainant’s project in December 2024. Random employees from Coli Studio would come to the property at the beginning of 2025. On or about March 12, 2025, Coli Studio broke ground on the project.
On September 9, 2025, Complainant issued a Cashier’s Check payable to Coli Studio in the amount of $46,500.00, accepted and signed by Yessica.
On or about September 17, 2025, Mr. Gilles realized that there was a different disassociation date on the Registrar website. Mr. Gilles spoke to the Registrar believing the dissociation went through back in November 2024. Mr. Gilles submitted a Personnel Change Form to the Registrar removing Coli Studio from Respondent’s license with the Registrar putting the disassociation date as September 18, 2025.
On September 18, 2025, Coli Studio removed Mr. Gilles as a shareholder.
On or about October 28, 2025, the Registrar received a Complaint against Coli Studio, using Mr. Gilles name and Respondent’s ROC License No. 347183, from Complainant alleging poor work with respect to the project.
The Registrar assigned the complaint to Investigator Todd Anderson.
On October 29, 2025, Investigator Anderson sent a jobsite inspection notification to Complainant and Respondent. Respondent was not aware of the project until Mr. Gilles received this notice.
On November 18, 2025, Investigator Anderson conducted a jobsite inspection with no one from Coli Studio present. Investigator Anderson’s jobsite general notes, in pertinent part, state the following:
Present at the Jobsite Inspection was Dimitri Gilles representing Redrock Construction LLC.
The Property Owner had originally contracted work with Coli Studios Inc who was unlicensed at the time.
Coli Studios Inc was using the license number held by Redrock Constructions LLC (ROC 347183)
Coli Studios obtained a new license on November 24th, 2025 (ROC 362507).
Per Asst Chief Edwards, change Respondent from Redrock Construction (ROC 347183) to Coli Studio (ROC 362507).
On November 19, 2025, in Complaint No. 2025-10685, Investigator Steven Avila issued a Dismissal Letter to that Complainant in regards to Respondent and Coli Studio, which stated as follows:
The Registrar received and investigated your complaint. The Registrar determined that there is not sufficient evidence to find that the Respondent Failed to meet minimum workmanship standards per A.A.C. R4-9-108.
It does not appear as though the respondent was liable for the work performed at the residence. Decision made due to no proceeds from the project going to the respondent as all funds were paid directly to Coli Studio and Coli studio was not authorized to contract using the respondent’s license number through the Registrar of Contractors.
Therefore, the Registrar will not issue a citation in this matter. The complaint is hereby dismissed.
Please understand that nothing in this letter is intended to prevent you from seeking relief in another forum.
On November 24, 2025, Coli Studio was issued a license with the Registrar. The Registrar’s Compliance unit advised Investigator Anderson to change Respondent, in this matter, to Coli Studio, since they were now licensed.
On November 25, 2025, Investigator Anderson was advised by the Compliance unit to move forward with Redrock Contracting as the Respondent, in this matter.
On December 1, 2025, Investigator Anderson issued a Written Directive to Respondent that provided as follows:
After investigation, the Registrar determined that you failed to meet the requirements of A.R.S. § 32-1154(A) and now issues this Directive requiring you to take appropriate corrective action. Failure to comply with this Directive constitutes a violation of A.R.S. § 32-1154(A)(22) and may result in the issuance of a citation, discipline of your license, and a civil penalty pursuant to A.R.S. § 32-1154(E) of up to $500.00. You must notify the Registrar’s assigned Investigator of your compliance with this Directive prior to 5:00 p.m. on December 23, 2025.

After the deadline in the directive expired, Investigator Anderson was notified that no corrective work had been performed.
On January 28, 2026, the Registrar issued a Citation against Respondent, charging possible violations of Ariz. Rev. Stat. § 32-1154(A)(3), namely Ariz. Admin. Code R4-9-108(B) and Ariz. Rev. Stat. § 32-1154(A)(22).
Hearing Evidence
Investigator Anderson testified that ultimately Respondent was responsible legally in this matter because the association with Coli Studio went from August 19, 2024 to September 18, 2025.
Ms. Dominguez testified that she and Complainant primarily dealt with employees of Coli Studio. Ms. Dominguez testified that she may believed she saw Mr. Gilles at the Coli Studio office once. Ms. Dominguez testified that Coli Studio reached out initially to finish the job and referred them to a Starlight Financial to sign a new contract. Ms. Dominguez was confused and did not want to sign off on another contract through Coli Studio or Starlight Financial. Ms. Dominguez further testified that she has became aware of others that had dealings with Coli Studio and tried to get them to sign a new contract through Starlight Financial.
Mr. Gilles testified that he had to get law enforcement involved once he realized all of the fraud that was being committed under Respondent’s license. The City of Phoenix Police Department report number is 26-00236969. Mr. Gilles testified that he started his own Backyard Living ADU company sometime at the beginning of 2025.
Administrative notice was taken of Respondent’s prior License record on April 7, 2026. Such prior License record reflected that Respondent’s License No. ROC 347183 was first issued on August 18, 2023, and was active. Such prior License record also reflected that there were seven open complaints.
CONCLUSIONS OF LAW
This matter lies within the Registrar’s jurisdiction.
Complainant bears the burden of proof to establish Respondent’s statutory violations by a preponderance of the evidence. A preponderance of the evidence means “[p]roof which leads the trier of fact to find that the existence of the contested fact is more probable than its nonexistence.”
The Tribunal has determined based on the testimonial and documentary evidence that this case as well as six other open cases should all be attributed to Coli Studio, Incorporated, ROC License No. 362507, which was the entity liable for the contracts entered into, for the work performed, and for the work abandoned, a factor that should be considered was when the contract was signed.
In this case, although Coli Studio was listed as a parent company of Respondent and/or Mr. Gilles was listed as a 25% owner, none of that ever came to fruition. Mr. Gilles was not involved in any projects that Coli Studio initiated, nor did he receive any monies from any of these projects. This matter is akin to identity theft, in that, Coli Studio placed Respondent’s ROC license number on its contracts to utilize Respondent’s license, without his knowledge, then entered into contracts with Complainant without including Respondent as planned. These unsuspecting customers entered into contracts with Coli Studio, Coli Studio accepted hundreds of thousands of dollars from customers, Coli Studio would start the project, and then abandon the project. Respondent was unaware of everything and received no compensation. The first time Respondent heard about these projects was when he received numerous Registrar complaints from different Complainants. Unfortunately, the Registrar had different investigators working these cases and there seemed to be no broader plan to handle all of these matters in a more coordinated fashion.
The evidence established and Mr. Gilles credibly testified that Respondent disassociated from Coli Studio on November 17, 2024, and he believed he was no longer associated with Coli Studio. As such, Mr. Gilles started his own ADU parallel business during the first quarter of 2025.
The evidence established that Complainant needs recourse against the proper contractor which would be Coli Studio. However, Respondent should take some of the responsibility for going into business with Coli Studio and registering Coli Studio as a parent entity through the Registrar. Based on the credible weight of the evidence, any contract signed by a customer with Coli Studio using Respondent’s ROC License number 34718, from August 19, 2024 to November 17, 2024, action against Respondent’s license is appropriate. Hence, Complainant has a viable action against Respondent since its contract was entered into with Coli Studio on October 25, 2024.
As such, Complainant has established that Respondent and Coli Studio violated Ariz. Rev. Stat. § 32-1154(A)(3), namely Ariz. Admin. Code R4-9-108(B) and Ariz. Rev. Stat. § 32-1154(A)(22).
RECOMMENDED ORDER
Based on the foregoing,
It is recommended that on the effective date of the Order, the Registrar shall suspend Respondent’s License No. ROC 34718 for one day.
Pursuant to Ariz. Rev. Stat. § 41-1092.08(I), the licensee may accept the Administrative Law Judge Decision by advising the Office of Administrative Hearings in writing not more than ten (10) days after receiving the decision. If the licensee accepts the Administrative Law Judge Decision, the decision shall be certified as the final decision by the Office of Administrative Hearings.
In the event of certification of the Administrative Law Judge Decision by the Director of the Office of Administrative Hearings, the effective date of the Order will be forty (40) days from the date of that certification.
Done this day, April 27, 2026.
