Garage to ADU Conversions in Roseville:
Fully Managed from Plan Check to Handover
If you are ready to convert your garage into a legal, permitted Accessory Dwelling Unit, you don't need a general handyman. You need a structural specialist who understands the City of Roseville’s specific plan check codes, setbacks, and utility requirements.
GBG Construction Inc
(CA License #1071343, Class B & D-28) handles the entire lifecycle of your garage conversion. We eliminate the friction of dealing with independent architects, structural engineers, and city planning desks by delivering a single, fully managed contract.

What We Handle:
No Finger Pointing, Single Source Responsibility
1: Architectural & Structural Engineering Review
Roseville Compliance
We don't guess on framing. We engineer structural overrides for existing garage walls, design roof tie-ins, and ensure the slab meets residential thermal and moisture-barrier requirements.
2: Roseville Plan Check & Permit Acquisition
Zero-Stress Navigation
We manage the submittal process with the City of Roseville Building Division. If the plan check requires corrections on structural details or energy calculations (Title 24), our team handles the resubmittals directly.
3: Mechanical, Electrical & Plumbing (MEP) Infrastructure
Built for Longevity
Garages lack the infrastructure for independent living. We handle heavy up-panel electrical upgrades, trench and route independent sewer/plumbing lines for the kitchen and bath, and design efficient ductless mini-split HVAC zones.
4: Framing, Insulation, and High-End Delivery
Turnkey Handover
From sistering joists to complete fire-rated drywalling, insulation upgrades, and premium interior finishes. We hand over a space that looks, feels, and operates like a luxury custom home.
