Nonna Homes, the Sacramento-area accessory dwelling unit builder that recently topped a regional growth list, has hit pause on taking new business while state officials review a stack of customer complaints. Homeowners and subcontractors say active projects have slowed to a crawl or stopped outright, with some jobs still unfinished and clients suddenly unsure about schedules and what happens to the money they have already paid. The freeze comes as ADU demand across the region keeps climbing, putting an uncomfortable spotlight on one of the market’s fastest-rising contractors.
Company pause and probe
As reported by the Sacramento Business Journal, Nonna Homes stopped taking new business in recent weeks while "state officials" investigate the company’s operations. According to the Journal, the timing is striking: the pause arrived less than six months after the firm was tagged as the region’s fastest-growing company of 2025. Homeowners with active contracts described an abrupt halt to sales activity and new project starts.
Public licensing data lists the business as Nonna ADU and Construction Inc., based in Rancho Cordova. Records from the California Contractors State License Board show license #1115116 is still active but carries a public complaint disclosure and a notice that the license "may be suspended at a future date" if specific personnel requirements are not met. That entry states that the board has received consumer complaints tied to the company.
Nonna Homes’ own marketing still pitches turnkey ADU packages and model floor plans, listing an office at 2941 Sunrise Blvd., Suite 120 in Rancho Cordova. On Nonna Homes' website, the firm promotes design-to-build services in both the Sacramento and Bay Area markets and highlights its Eco Series ADUs. As of this reporting, the site had not posted any explanation about the decision to suspend new business.
What homeowners are reporting
Customer listings and review platforms such as MapQuest/Yelp carry a run of critical reviews describing lengthy delays, warranty frustrations and work left unfinished. One review dated Jan. 6 recounts a call in which the company reportedly said it had "officially closed for new business," while the firm’s Better Business Bureau profile shows an open file with multiple consumer contacts. Those accounts have led some customers to look into civil options while they wait to see what regulators decide.
ADU market in context
Accessory dwelling units have become a major part of California’s housing strategy, and the numbers show why. A state auditor’s report and information from the California Department of Housing and Community Development document a spike in ADU permits, from roughly 8,900 in 2018 to more than 30,000 in 2024. That boom has enticed a wave of new builders into the niche. Experts say the rapid growth can stretch small contractors’ capacity and increase risks for homeowners when companies try to scale up faster than their systems and staffing can handle.
Legal and regulatory next steps
The Contractors State License Board is authorized to investigate complaints, issue citations, and suspend or revoke licenses when it finds violations. Consumers can submit a construction complaint through the board’s online system. CSLB materials outline how complaints are screened, mediated, and investigated and note that a public complaint disclosure can appear before any formal enforcement action is finalized. Homeowners who believe they have been harmed are advised to hang on to contracts, payment records, and permit documents so they can support any administrative or civil case.
For now, the Sacramento Business Journal remains the most detailed public source on the company’s pause while Nonna Homes’ online listings stay live. Customers looking for current information should keep an eye on the firm’s contact page and official license record, and may also want to check with their city building department or an attorney about permit status, potential liens, and next steps. We will continue to watch state filings and company notices for any official updates or statements.
