Which document shows where utilities connect to a building and its site?

• A. Site plan
• B. Utility drawings
• C. Floor plan
• D. Elevations

Answer: (B)

When detailing how utilities tie into a building, utility drawings are the go-to. They include plan views and profiles for the various services—water, sewer, gas, electric, and communications—showing the exact points where the service lines enter the building, meter locations, main shutoffs, backflow preventers, and the routes from the street or property line into the structure. This level of detail is needed to install, inspect, and coordinate the interfaces with the building systems. A site plan covers the overall property layout—building footprint, access, landscaping, and general utility corridors—but it doesn’t provide the detailed connection points, sizes, or equipment needed for actual connections. Floor plans show interior rooms and walls, while elevations depict exterior faces and heights. So the document that shows where utilities connect to a building and its site is the utility drawings.
