Joy Line Homes

Joy Line Homes is a California design-build modular home builder and manufactured (HUD-code) home dealer. We create modern prefab and custom factory-built homes—plus ADUs—so homeowners can move faster without giving up quality. What makes our process different: • Design-Build Modular Homes: architect-driven plans, engineering + Title 24 coordination, and a clear path from concept to keys • Schedule-Driven Construction: overlap factory production with site prep to shorten total duration • Full-Scope Site Work + Foundations: grading, drainage, retaining walls, utility trenching, permanent foundations, and anchoring • Set Day Logistics: transport routes, staging plans, crane day coordination, and safety • Interior Finish & Close-Up: module seam work, trim, paint, cabinets, flooring, and punch-list completion • High-Performance & All-Electric Options: heat pump HVAC, induction, and upgraded envelope specs • Wildfire-Wise & Rebuild Packages: solutions aligned with common fire-zone requirements We also support new manufactured homes for sale (single-wide and double-wide), including site feasibility, permitting support, financing guidance, delivery/set, and post-install warranty coordination. Primary service areas (CA): Los Angeles County (Santa Monica, Pacific Palisades), Santa Clara County / San Jose, Santa Cruz & Monterey, Santa Barbara/SLO, Riverside + San Bernardino, and the Bay Area (SF, Oakland, Fremont, Walnut Creek, Palo Alto, Sunnyvale).
