Which of the following is not a common type of plan?

• A. Plumbing plan
• B. Electrical plan
• C. Painting plan
• D. Floor plan

Answer: (A)

The idea to focus on is which plan types are typically encountered and relied on for safety and coordination in building documentation. Floor plans and electrical plans are standard because they directly affect life-safety decisions—room layouts, exits, and the placement of wiring and fire-related devices are core to compliance and inspection. A painting plan is less of a universal, separate drawing in many plan sets; it’s more about finishes and aesthetics than life-safety systems. In contrast, a plumbing plan is often treated as part of a separate plumbing/MEP drawing set rather than a standalone plan used across safety reviews, so it isn’t regarded as a common type of plan in the typical inspection context. That’s why it’s identified as the not-common option.
