ADU construction turns unused space or a garage into a legal, fully permitted dwelling in Garden Grove.

Why Choose Ridgeline Western Construction for ADU Construction in Garden Grove
Accessory dwelling units in Garden Grove can add valuable living space, offer extra rental income, or give families flexibility. From new detached builds to garage conversions, ADUs must follow zoning, setback, egress, and fire regulations for Orange. Placing and designing these units also often involves utility tie-ins, dedicated addresses, and plan check reviews.
Ridgeline Western Construction manages the entire ADU process, beginning with engineering and design coordination. We self-perform framing, ensuring every new structural connection is by-the-book using engineered lumber where required, with seismic hardware, shear panels, and connectors as specified by city drawings. Roofing, siding or stucco, windows and doors, insulation, and drywall go in order, scheduled so the project keeps moving without long delays between trades. Licensed subcontractors are brought in for the electrical, plumbing, and mechanical work, all supervised and scheduled under our main contract—not left for you to coordinate. The biggest variable in timing is usually city plan check and utility approvals, not the build itself.
Each step is closed by city inspections and thorough documentation, ending with a certified permit record. Once finished, you receive everything needed to legally rent, sell, or use the ADU for family. This includes stamped drawings, inspection records, and proof of legal conversion or new unit status in Garden Grove or Orange. You know each step is handled, every compliance box checked, and the result is an ADU built to last.

Owner-Led Structural Framing
The structural tie-in and framing for your Garden Grove ADU are managed and performed by the owner, not outsourced. Engineered lumber, load transfer connections, and seismic details follow engineered and city-approved plans. This focus improves both inspection outcomes and long-term durability, giving you real confidence in the structure.

What Our Clients Say about us..
"I connected with Steven Moreno at Ridgeline Western Construction about a year ago when I was scoping out a project. Steven’s knowledge blew me away from framing, additions, new construction, materials, etc. He broke everything down like it was nothing & in a way that I actually could understand. The company is based out of Fontana and covers a huge range from San Bernardino and Riverside all the way through Los Angeles and Orange County. So if you’re in that area and need a general contractor that you can rely on then I would highly recommend Ridgeline Western Construction to get the job done right."
