Attached 2-car garages are standard in the vast majority of Houston suburban homes. Popular renovations include epoxy floor coatings, overhead storage systems, wall storage panels, mini-split AC for cooling, and workshop or gym conversions. Houston's intense summer heat — regularly exceeding 100°F — makes thermal management the top priority for any usable garage space.
