Lean construction is a method of optimizing the building process to eliminate or minimize waste and maximize efficiency. It approaches the construction of homes with an emphasis on eliminating any unnecessary costs, such as those associated with labor, materials, and waste. Lean construction also relies heavily on strong communication between all parties involved in the process, as well as collaboration and feedback. Additionally, lean construction generally promotes standardization and modularization techniques, which can reduce the time required for completing each task and ultimately, project. This allows contractors to complete more projects in less time, making the entire process more efficient.

The implementation of lean construction methods can also reduce errors during construction, meaning fewer reworks are needed resulting in fewer mistakes that could turn into costly repairs down the road. Even beyond all of these benefits, lean residential construction has been known to improve safety conditions for workers onsite by reducing clutter and increasing organization on the job site.
