Before agreeing to a home standby generator installation, ask who will handle the permit process and how the proposed location will be checked. This homeowner checklist helps you prepare questions for an installer; it does not determine the rules for your address.
Start with the exact equipment and property
Write down the generator model, proposed fuel supply, transfer equipment, and installation address. Ask the installer to attach a site sketch to the proposal. Keep the quote, manufacturer installation manual, and any approval documents together so that a change to the equipment or location can be reviewed against the same project record.
Questions to ask before signing
- Which local office will review this project?
- Which applications does this particular installation require?
- Who submits each application and pays each fee?
- Are those costs included in the written quote?
- What documents must I provide as the homeowner?
- Who confirms the proposed generator location against the model installation instructions?
- Does the proposal include a site drawing showing the generator, house, and relevant openings?
- Who coordinates any fuel-supply work?
- Are utility arrangements included or excluded?
- What inspections must be completed before project handover?
- Who schedules those inspections?
- Who pays for corrections if the proposed installation fails review?
- What happens to the schedule if approval takes longer than expected?
- Will I receive copies of the final approval documents?
- What change-order process applies if the approved location differs from the quoted location?
Check the location before accepting a fixed scope
Generac directs owners to the installation manual for clearance requirements and site preparation. Use the manual for the exact model rather than borrowing a distance from a different generator. Ask your installer to explain the chosen location and document the applicable requirements. See Generac clearance guidance.
Separate approval timing from installation timing
Generac identifies permits, dealer availability, site preparation, and gas-line preparation as factors affecting timing. Request separate estimated dates for application, approval, equipment delivery, installation, and handover. Treat these as planning estimates and ask how delays will be communicated.

Compare quotes using the same questions
Generac says a standby quote typically covers the unit, transfer switch, installation labor, electrical work, fuel connections, and needed site preparation. Ask each bidder to mark permit handling and inspection coordination as included, excluded, or awaiting review. An unanswered item should remain visible in your comparison rather than disappearing into a single total. See Generac quote guidance.

Frequently asked questions
Does this checklist confirm which permits I need?
No. It provides questions to take to the installer and relevant local office. No address-specific permit determination is made here.
Should I rely on an installation-day estimate alone?
Request the full project timeline, including the approval and preparation stages identified above.
What if a quote leaves permit responsibility unclear?
Ask for written clarification before accepting it. Record who handles submission, fees, inspection scheduling, and corrections.
