Joy Line Homes

Joy Line Homes is a California-based design-build company specializing in Accessory Dwelling Units (ADUs), modular homes, manufactured homes, tiny homes, and wildfire rebuild solutions. Through its dedicated ADŪRA ADU brand, the company delivers modern, factory-built housing solutions that combine architectural design, advanced engineering, and precision manufacturing. With offices serving Northern, Central, and Southern California, Joy Line Homes helps homeowners create energy-efficient, high-quality backyard homes with predictable timelines and transparent pricing.

Operating as a full-service ADU provider, Joy Line Homes manages every phase of an ADU project—from feasibility studies and architectural planning to engineering, permitting, factory-built construction, transportation, installation, utility connections, and final inspections. Homeowners can choose from a wide range of professionally designed ADU floor plans or customize layouts to meet their specific needs. The company’s factory-built approach minimizes weather delays, improves quality control, and shortens construction timelines while maintaining compliance with California building standards.
