Professionals minimise delays, prevent costly rework, and help you take full advantage of ADU zoning allowances.
The Garage Conversion to ADU Process
A typical garage conversion to ADU follows a structured workflow.
Initial consultation and feasibility review to discuss goals, garage conditions, setbacks, utilities, and zoning constraints.
Site assessment and measurements to evaluate the existing structure, foundation, utilities, and space limitations.
Design and layout creation with floor plans showing living areas, kitchen, bath, storage, and circulation.
Engineering and compliance planning including structural, mechanical, electrical, and plumbing plans prepared to code.
Permitting with plan submissions to the City of Roseville and responses to plan check comments.
Construction including demolition, framing, utilities rough-in, insulation, drywall, finishes, and fixtures.
Inspections and approvals coordinated for each discipline.
Final walk-through to confirm completed work meets design, code compliance, and quality expectations.
Professional coordination ensures the job stays on time and on budget.
