6 Garage Mistakes You Can Never Fix Cheaply Later

A garage can fit your vehicle on paper and still fail in daily life. I walk through six costly planning mistakes that are difficult—and expensive—to correct after the slab, framing, and drywall are finished. I explain how I evaluate: • Garage dimensions beyond basic vehicle size • Vertical clearance for doors, lifts, storage, and equipment • Electrical capacity for future tools and vehicles • Drainage before the concrete is poured • Lighting based on task zones • Plumbing options for a future utility sink I also share a practical three-pass planning process to help catch hidden conflicts before construction begins. My guiding rule is simple: anything buried under concrete or sealed inside a finished wall should be decided before it starts creating daily friction. 0:00 Costly garage planning mistakes 1:31 Sizing beyond the vehicle 2:18 Planning vertical clearance 3:17 Future-proofing electrical capacity 4:45 Designing drainage before concrete 5:36 Lighting by task zones 6:24 Preserving utility sink options 7:13 Three-pass planning process #GarageDesign #GaragePlanning #HomeBuilding #HomeImprovement #ConstructionTips #GarageWorkshop
