Buying a Home With a Generator: Inspection Checklist

Ask for the generator and transfer-switch model information, installation documents, owner manuals, service records, and any available commissioning information. Obtain details of the fuel supply and whether a propane tank is owned or leased. Keep commercial agreements separate from the physical equipment sale.

If records are missing, treat that as an information gap rather than proof that the system is defective. An assessment can help establish a starting point for maintenance and operation, though it cannot reconstruct every event in the equipment's history.

A generator connected to a house may serve selected circuits or a broader arrangement with load management. Ask for a circuit list and an explanation of what may be unavailable during an outage. Pay particular attention to well pumps, heating, cooling, and any electric appliances you plan to add.

A seller's statement that “it runs the whole house” should be clarified. Does that mean all circuits are connected, or that every large appliance can operate simultaneously? Those are different claims.

• Visible condition and relevant maintenance needs.
• Reported alarms or known operating problems.
• Generator, transfer equipment, and fuel-system compatibility questions.
• Suitability of the existing load plan for your intended use.
• What functional testing is appropriate and authorized.

Coordinate access and testing with the seller or responsible party. A general home inspection and specialized generator service have different scopes; ask what each includes.

Confirm whether monitoring accounts, service agreements, and warranty rights can transfer. Follow the actual provider and manufacturer process; do not assume credentials or account access should simply be handed over informally. Update contacts after closing through the authorized channels.

Ask about the last extended outage, recent repairs, and any change to household equipment. These questions can reveal useful operating history without assuming a fault exists.

Create a service calendar from the model documentation and known service history. Learn the owner-facing controls, emergency contacts, and safe access requirements. If the house will be seasonal, establish who will respond to alerts when you are away.

Christopher Power Systems offers generator maintenance and diagnostics. Provide the available records when asking about an assessment. A written list of findings and limitations is more useful than a verbal statement that the generator “looks fine.”
