RIC Robotics and K4K Construction Complete Printing of Sacramento’s First Permitted 3D Concrete-Printed Home

Major construction milestone demonstrates how autonomous building technology is advancing code-compliant residential development and helping establish a pathway for future 3D-printed housing projects

RIC Robotics, a leader in autonomous construction technology, and K4K Construction today announced the successful completion of printing for Sacramento’s first permitted 3D concrete-printed home, marking a significant milestone for residential construction and demonstrating how robotic building technologies are moving from pilot projects to real-world, code-compliant housing.

The 1,200-square-foot accessory dwelling unit (ADU) was printed in just 12 days, making it one of the fastest seismic complaint wall systems completed with 3D concrete-printed systems in the U.S. Developed by K4K Construction using RIC Robotics’ autonomous construction technology, the project also established the first permitting pathway for a 3D concrete-printed residence in the City of Sacramento, creating a framework that could support future residential projects utilizing the technology.

"When we decided to build this home, it wasn't simply about trying a new construction method, it was about proving that innovative technology can deliver high-quality, code-compliant housing while helping address some of the biggest challenges facing our industry," said David Gonzalez, Founder, K4K Construction. "Building this home for our own family gave us complete confidence in technology, and reaching this milestone reinforces our belief that autonomous construction is a practical solution that can help shape the future of homebuilding."

The project carries special significance for David Gonzalez and his wife, Estelle Gonzalez, who chose to build the inaugural home in their own backyard before introducing the technology to prospective homeowners. Designed as a residence for Estelle’s parents, the ADU serves not only as a family home but also as a proof of concept demonstrating that innovative construction methods can successfully meet the rigorous standards required for residential development.

To bring the project to life, K4K Construction and RIC Robotics worked closely with the City of Sacramento throughout the permitting process, helping establish a code-compliant pathway for future 3D concrete-printed residential construction. The collaboration demonstrates how builders, technology innovators and municipalities can work together to responsibly introduce new construction methods while maintaining the safety, engineering and quality standards expected of traditional residential development.

"This project demonstrates that autonomous construction has moved beyond experimentation into real-world residential development," said Ziyou Xu, Founder, RIC Robotics. "By successfully delivering a permitted residential project, we're demonstrating how robotics can help builders meet growing housing demand more efficiently while maintaining the quality and standards homeowners expect."

Residential builders across the United States continue to face persistent labor shortages, rising construction costs and growing demand for housing. As the industry explores new ways to improve productivity while maintaining quality and safety, projects like this demonstrate how autonomous construction technologies can complement skilled labor and expand the industry’s capacity to deliver much-needed homes.

Completion of the printed wall system marks a major step toward delivery of the finished residence, with the project now progressing into the next phase of construction, including roof installation, mechanical, electrical and plumbing systems, interior finishes and inspections.

As communities across the country seek innovative approaches to expanding housing supply, this project is a pioneer in demonstrating how collaboration between builders, technology providers and local governments can help accelerate the responsible adoption of next-generation construction methods while maintaining the high standards homeowners expect.
