Garage walls can be divided into major or minor storage walls. Major and minor storage walls are defined by the amount of space available to use for storage.
Major wall: A major storage wall accommodates storage from ceiling to floor and across the span of the wall, even when cars are parked in the garage. This is typically the wall in front of the vehicles. Since most of the wall is available for storage, items that are used regularly should be stored on a major wall.
Minor wall: A minor storage wall is a wall where storage space is limited, typically because you need to allow room for car doors opening and walkway space. The bottom half of a minor wall is not available for storage. Since items stored along minor walls are stored higher, a minor wall is a good place for seasonal items because they’re not used as frequently.
There’s a lot of variety in what’s stored in the garage. Using this booklet as a guide will give the garage designer room to design the space appropriately for all home buyers.
