Start with the photographed equipment
Review overview photos and list visible items buyers could reasonably associate with the generator: enclosure, tank, trailer, transfer switch, cables, exhaust components and loose spares. Give each item one status: included, excluded or undecided. Do not let an undecided accessory quietly become part of a confirmed offer.
Describe the physical boundary
Ask responsible site personnel to explain which equipment belongs to the offered package and which remains part of the building. Use a labeled photo or inventory reference where helpful. Describe removal boundaries for qualified contractors to review; do not direct a buyer to cut or disconnect equipment based solely on a marketing photo.
Resolve shared and separately owned items
Check whether accessories serve other units or are owned by another party. Flag that uncertainty early. An item stored beside the generator may belong to a contractor or another project. Confirm sale authority through the responsible owner before including it, and avoid promising that proximity establishes ownership.
Put the final schedule beside the offer
Attach the included-and-excluded list to the final equipment description and date it. For example: enclosure included; wall-mounted transfer switch excluded; loose spare filters included as inventoried. If the buyer changes the requested package, obtain an updated offer and removal scope. Keep the old schedule so the change can be traced.
