TL;DR
A lean-to attachment is a single-slope roof structure added against the wall of an existing shed, garage, or barn, sharing the host wall while its low side bears on new posts, creating cheap covered space for firewood, equipment, or animals. Sound construction flashes the joint where the new roof meets the host wall, sets posts on footings or anchored piers, and slopes the roof away from the building at 1 in 12 or steeper depending on roofing type.
What it means
A lean-to attachment is a single-slope roof structure added against the wall of an existing shed, garage, or barn, sharing the host wall while its low side bears on new posts, creating cheap covered space for firewood, equipment, or animals. Sound construction flashes the joint where the new roof meets the host wall, sets posts on footings or anchored piers, and slopes the roof away from the building at 1 in 12 or steeper depending on roofing type. Zoning often counts it toward accessory-structure size limits, and snow shed from the upper roof onto it deserves design attention in cold climates.
