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.

How to resolve conflicting answers about the approval process
If the installer, a sales representative, and a local office give different answers, record the exact question each person was answering. One may be discussing application submission while another is discussing the inspection appointment or the proposed location. Send a short written clarification request identifying the address, current equipment schedule, drawing version, and unresolved point. Ask the responsible reviewing office or contractor to explain which answer applies to this project.
Keep the response with the project tracker. Do not select the answer that offers the quickest installation date merely because it is convenient. Ask the installer to explain whether the clarification changes the quoted work, documents, or planned sequence. This guide cannot decide a local approval requirement, but it can help you prevent conflicting verbal summaries from becoming an unnoticed gap in the project.
Example: an unanswered application item
Imagine the sales proposal states that applications are included, but the contractor later asks the homeowner to supply a document that was never identified. Ask what the document is, who prepares it, who checks it, and when it must be supplied. Record whether the request changes a cost or a milestone. The aim is not to assume the contractor made an error; it is to make the next action and its owner explicit.
If the response introduces a new reviewing party or a revised equipment drawing, add a separate tracker row rather than overwriting the original task. Keep the date and reason for the revision. When several contractors are involved, ask the project coordinator to confirm that they have the current document set. This hypothetical example demonstrates record keeping, not a rule about the forms every generator installation must use.
Request evidence without assuming a universal certificate
Ask the responsible party what confirmation is provided for each actual stage of your project. That could be an application reference, a written response, a scheduled inspection notice, or the relevant completion information. The correct document depends on the process the office and installer identify. Do not request a certificate with an invented name or assume a receipt proves every later requirement has been completed.
Record what has been confirmed and what is still pending in separate fields. “Submitted,” “reviewed,” “appointment requested,” and “completed” describe different events. Ask the installer how those labels correspond to the actual process rather than treating all of them as approval. A clear status lets you follow up on the remaining task without restarting an already completed one.
Prepare a useful final-record index
At handover, make an index of the final equipment schedule, current site information, relevant application and inspection records, manuals, and service contacts. Check that document versions refer to the equipment actually installed. Where a promised record is missing, list the owner and next follow-up date. Keep these administrative records separate from the household operating instructions so each is easy to find.
Retain earlier drawings as superseded versions if they explain a change, but mark the current record clearly. If a later contractor reviews the system, the index should help identify the installed models and the completed project without guessing from a photograph. This is the practical purpose of the checklist: making responsibility, status, and the final record understandable from beginning to end.
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.
A simple project record
| Item | Record to request |
|---|---|
| Equipment | Exact model and installation manual |
| Location | Installer site sketch and placement review |
| Applications | Responsible person, fee, and submission status |
| Inspections | Appointment, result, and any corrections |
| Handover | Final documents and contact for unresolved items |
Build an approval tracker before the equipment arrives
Use one project tracker with a separate row for each question your installer or local office identifies. Suggested columns are the reviewing office, application description, applicant, fee allowance, documents requested, submission date, current status, inspection contact, and final record. This is an organizational worksheet, not a claim that every project needs the same applications. Leave a field marked “not yet confirmed” when you do not have an answer.
For example, imagine an installer says permit handling is included but the written proposal lists only equipment and labor. Your next action is to request a revised scope identifying who submits the paperwork, which fees are covered, and what is excluded. Do not turn a verbal assurance into a completed tracker entry. Save the actual confirmation alongside the proposal so a replacement project contact can understand the agreement.
What to do when the proposed location changes
Ask the installer to update the drawing and explain whether the change affects any submitted documents, fuel work, electrical work, site preparation, or inspection arrangements. Record the answer before agreeing to a revised schedule or price. A photograph of the new location can help the discussion, but it is not a substitute for the model-specific installation instructions or the relevant office’s review.
Keep the original and revised drawings clearly dated. Write the reason for the change in the tracker, such as a homeowner preference or an unresolved site question. Avoid deleting the previous version: the change record helps explain why the signed quote and final installation plan differ. Ask the responsible professional to identify which documents are authoritative for the work that will actually proceed.
Separate these four project milestones
- Scope confirmed: the equipment, proposed location, responsibilities, and exclusions are written down.
- Applications resolved: the responsible parties have identified what this address requires and documented the applicable status.
- Installation ready: the installer confirms that equipment, site preparation, and other dependencies are ready for the planned work.
- Handover documented: you receive the relevant final records, operating instructions, and a contact for outstanding questions.
These are suggested tracking milestones. They do not replace official approval stages. Ask your installer how each milestone maps to this project’s actual process. Generac’s installation overview identifies preparation and permitting among factors affecting timing; avoid interpreting an installation-day appointment as confirmation that all earlier work is resolved.
Resolve exclusions before comparing prices
Use three labels in your quote comparison: included, excluded, and awaiting confirmation. A blank permit line belongs in the third category until the bidder answers it. Ask whether an allowance has a defined scope and what happens if the actual fee differs. Do the same for inspection coordination and any corrections. Request the proposed change-order procedure rather than assuming that an extra charge will be handled in a particular way.
Keep equipment costs separate from project administration questions. This guide focuses on responsibility and records; for the full purchasing scope, use our installation quote checklist. For the electrical contractor’s part of the proposal, consult the electrician quote guide.
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.
