        "text": "Costs for a garage addition depend primarily on square footage, foundation requirements, roof tie-ins, and interior finishes. A basic unfinished shell with standard overhead doors, concrete slab, and basic lighting costs significantly less than a fully conditioned space. Adding insulation, drywall, mini-split heating and cooling, upgraded electrical subpanels for EV charging or shop equipment, or a second-story living suite will substantially increase the budget. Site factors like sloping terrain that requires engineered retaining walls or extensive grading also directly influence overall project expenses.",
