A reflected ceiling plan (RCP) is a drawing used in architecture and interior design that shows what is located on the ceiling of a space. The term “reflected” refers to the concept of looking down at the ceiling as if it were mirrored onto the floor plan.

An RCP typically includes:
• Lighting fixtures and layouts
• Ceiling heights and changes in elevation
• Soffits, bulkheads, and ceiling features
• Air diffusers and return grilles for HVAC systems
• Sprinkler heads and other life safety elements

These plans are used to coordinate between architectural, mechanical, electrical, and fire protection systems. Proper coordination helps avoid conflicts during construction and ensures that all ceiling-mounted elements fit within the available space.

Reflected ceiling plans are commonly required for commercial projects, tenant finish-outs, and renovations where multiple systems must be integrated within the ceiling.

A clear and accurate RCP supports construction, improves coordination between disciplines, and helps maintain design intent throughout the project.
