A building inspector is a municipal official who examines construction projects to ensure they comply with approved permits, building codes, and safety standards. Inspectors visit construction sites at key stages—foundation, framing, electrical, plumbing, and final completion—verifying that work meets requirements before construction can proceed to the next stage. They have authority to stop work, require corrections, or refuse occupancy for buildings that do not comply. Building inspectors must understand complex technical codes and balance enforcement with practical construction realities. Their work protects public safety by ensuring buildings are structurally sound, fire-safe, and properly equipped.
