Layout is a systems decision
Moving a sink can change supply and drain routes. Moving a range can change fuel, circuit, hood, and duct requirements. An island can affect power, clearances, flooring, support, and ventilation. Price the downstream effects, not only the visible cabinet move.
Plumbing scope should name every connection
List sink, faucet, dishwasher, refrigerator water, disposer, filtration, gas, shutoffs, drains, vents, and any piping replacement. State what is reused, moved, capped, or new. Ask how concealed conditions are documented before corrective work proceeds.
Electrical scope should follow the final appliance list
Supply exact appliance specifications when available. Record new or reused circuits, receptacles, lighting zones, switches, controls, under-cabinet lighting, island power, panel assumptions, testing, labeling, and finish repairs. “Electrical as needed” is not a comparable line item.
Ventilation needs a complete route
Define hood type, airflow basis, duct size, route, exterior termination, makeup-air question where relevant, cabinet coordination, roof or wall work, weather sealing, controls, and final testing. A decorative hood without an agreed duct path is not a ventilation plan.
Structural changes need an early decision
Do not assume a wall is non-load-bearing from appearance alone. Openings, posts, beams, ceiling changes, or concentrated island loads can require professional review and a building permit. Mark the question early so cabinet drawings and budgets do not depend on an unsupported assumption.
Schedule inspection access
Where permits apply, rough work may need inspection before insulation, drywall, cabinets, or finishes cover it. The proposal should identify who schedules each inspection, who is present, what must remain open, and what happens if correction is required.
Hold one marked-up coordination meeting
Place the final cabinet drawing, appliance sheets, lighting plan, plumbing points, and hood route on the table together. Mark the person responsible for every unresolved dimension and connection. Do not let separate trades solve a conflict independently on site: a moved outlet can collide with a cabinet rail, and a shifted drain can reduce storage. Issue the agreed corrections as one dated revision before rough work or fabrication proceeds.
Any new route, connection, upgrade, or repair should also be added to the cost plan before it is authorized.
Record the decision in writing.

Frequently asked questions
Can I keep the same layout but still need trade work?
Yes. Replacement appliances, lighting, ventilation, sink work, damaged services, or code-related corrections can create trade scope even when locations stay similar.
Who decides whether a wall can be removed?
A qualified professional must assess the actual building. The site and a sales estimate cannot determine structural function from a photo alone.
Why provide appliance models before rough work?
Installation data can affect dimensions, circuits, fuel, water, ventilation, clearances, and cabinet panels.
