MEP
Also called: Mechanical, Electrical, Plumbing
MEP is shorthand for the Mechanical, Electrical, and Plumbing systems of a building. MEP work includes HVAC equipment and ductwork, electrical panels and wiring, plumbing supply and waste lines, gas lines, and tied-in fire suppression. MEP rough-in is the inspection milestone before drywall closes the walls.
Why this matters for renovation projects
MEP shows up on permits, contracts, or estimates that Renology covers across LA, San Diego, San Francisco, Seattle, Portland, and Denver. Most homeowners encounter the term once a project is already mid-flight, when there is no time to learn its mechanics without slowing the contractor. Knowing what it means before signing the contract is the difference between a clean project and an avoidable surprise. For how Renology calibrates cost ranges against permit valuations and contractor invoices, see the methodology.
