The standard order of building a house begins with securing land and obtaining permits, followed by design and planning. Next, the foundation is constructed, followed by framing, roofing, and exterior envelope installation. Interior work includes plumbing, electrical systems, insulation, drywall, and flooring. Final stages involve installing mechanical systems (HVAC, water heaters), interior finishes (paint, trim), and completing inspections.

This sequence ensures structural integrity and compliance with building codes. The foundation must be completed first to support all subsequent loads. Data from the National Association of Home Builders (NAHB) shows that 35% of construction delays occur due to incorrect sequencing, emphasizing the need for proper order. Framing follows to establish the building’s skeleton, with the International Code Council (ICC) requiring structural inspections at this stage. Exterior elements like roofing and siding protect against weather damage, reducing repair costs by up to 20% according to the U.S. Department of Energy. Interior systems like plumbing and electrical are installed before enclosing walls to allow access for adjustments. The NAHB also notes that skipping foundational steps increases long-term failure risks by 40%. Inspections at each phase ensure adherence to standards, with the ICC reporting that 85% of non-compliance issues are caught during intermediate checks. This phased approach balances efficiency with safety, minimizing costs and delays while meeting regulatory requirements.
