Final answer:
Rough inspections of essential systems must be done prior to insulation and drywall installation to ensure safety and building code compliance.
Step-by-step explanation:
Rough inspection of plumbing, mechanical, gas, and electrical systems must be done prior to insulation and drywall installation. This type of inspection is crucial as it ensures that the foundational aspects of a building's infrastructure are correctly installed and are in compliance with building codes. Once this inspection is successfully completed, and any issues are addressed, the insulation and drywall may be installed, with further inspections to follow to guarantee the safety and livability of the building.
Rough inspections of plumbing, mechanical, gas, and electrical systems must be done prior to the final inspection. Building codes in many developed countries specify safety requirements that a house must meet to be considered livable. These requirements include running water, proper ventilation and heating systems, structurally safe construction, smoke detectors, and correctly installed electrical wiring.
