What's Actually Included in a Professional Home Generator Installation?

A professional home standby generator install in Jacksonville is more than dropping the unit on a pad and connecting two wires. A real turnkey install — the kind that should be quoted as a single all-in price — includes about a dozen line items that span site prep, electrical, gas, permitting, and post-install commissioning.

This post is the line-by-line breakdown of what's in a complete install quote, why each piece matters, and which items get broken out as adders when conditions warrant.

The standard inclusions

Every install we quote includes these as base scope:

1. The generator unit itself

The biggest line item — typically 50–60% of the total. This includes the unit, manufacturer warranty registration, and any factory-fit accessories (remote monitoring receiver, battery, etc.).

2. Automatic transfer switch (ATS)

The component that physically disconnects your home from the JEA grid and connects it to the generator when the grid drops, then reverses when grid power returns. This is what prevents backfeed, which is why permits and inspections specifically focus on the ATS.

The ATS is matched to the generator size and the home's main panel ampacity. Common Jacksonville sizes: 100A, 200A whole-home, or partial transfer 100A.

3. Concrete or composite pad

The unit sits on a code-required raised pad — both for ground clearance during heavy rain (relevant in Northeast Florida flood plains) and for vibration isolation. Composite pads are the modern standard; some older spec calls for poured concrete. Either way, it's part of the install.

4. Gas line tie-in (within reasonable distance)

The fuel connection from your existing gas meter or propane tank to the generator. "Reasonable distance" in our quotes means up to ~25 feet of new gas line. Beyond that, a long-run gas line gets quoted separately.

This includes:

• New gas piping sized for the unit's BTU rating (undersized gas line = generator starves under load)
• Gas valve at the unit
• Pressure test
• Bonding per code

5. Electrical panel work

Includes:

• Pulling new conductors from the generator to the ATS
• ATS installation in line with the main panel (usually adjacent or in the same enclosure)
• Grounding electrode and bonding to the existing ground system
• Breaker labeling per NEC

6. City of Jacksonville + Duval County permits

Both an electrical permit and a gas permit. We pull these in our name, with our license, on your behalf. Cost is bundled into the quote — typically $150–$400 depending on county and size.

7. Startup and commissioning

After install:

• First fuel-system bleed and verification
• Manual start, run-up, and load test
• Programming the ATS for your home's specifics
• Setting the weekly self-test schedule (we default to a weekday afternoon when most people aren't home)
• Connecting the unit to the manufacturer's monitoring app (Mobile Link for Generac, OnCue for Kohler, etc.)

8. Both inspections

Electrical rough-in inspection and final inspection, scheduled and attended by us. You don't need to be home for these (we coordinate with the inspector directly).

9. First-year maintenance (most reputable installers)

The first annual service — oil change, filter change, battery check, transfer test, leak inspection — is typically included in the install price. After year 1 it transitions to a maintenance plan or per-visit service. Worth confirming this is in your quote; some installers exclude it.

10. Operator walkthrough

We walk you through the basics: how to read the unit's status indicators, what the weekly self-test sounds like, what to do if the unit doesn't transfer in an outage, and how to silence non-emergency alerts on the app.

What gets broken out as adders

These show up on the on-site quote as separate line items when conditions require them:

| Adder | When it applies | Typical cost | |---|---|---| | Long gas run (>25 ft) | Gas meter is far from the planned generator location | $50–$80 per linear foot | | Propane tank set | Home is on propane; tank needs install or upsize | $3,000–$5,000 (250-gal underground) | | Panel upgrade | Existing panel is at capacity or under-rated | $1,500–$3,500 | | Trenching through concrete | Driveway or patio in the install path | $300–$1,200 depending on length | | HOA architectural review | Mandarin, Nocatee, Ponte Vedra communities | $50–$200 (some HOAs charge a review fee) | | Tree clearing or major landscape work | Path to install location requires removal | Quoted by an outside arborist if extensive |

We surface every one of these during the on-site quote — not after install begins. The "surprise change order" pattern is one of the worst things in this trade, and we don't do it.

What's typically NOT included

Things some homeowners expect that aren't in a standard install scope:

• Decorative landscape restoration. We restore the install area to baseline (sod, simple plantings). We don't redo specialty landscaping, fountains, or specialty plantings.
• Interior wiring upgrades. If you want a specific circuit added or moved as part of the project, that's separate electrical work. We can quote it.
• Furniture moving. If the panel is in a finished basement or behind a built-in, you handle access clearing.
• Any work past the gas meter. If your gas service from the street is undersized, that's a JEA / TECO Peoples Gas project, not ours.

What "turnkey" actually means

A turnkey install means you sign a single contract for a single price, and the installer manages every step — site prep, materials, labor, permits, inspections, startup, walkthrough. You don't coordinate with separate electrical, gas, and concrete contractors. You don't pull permits yourself. You don't schedule inspections.

If a quote has multiple contracts (one for electrical, one for gas, one for the unit purchase), it's not turnkey — and you become the project manager. That's a bigger commitment than most homeowners realize until they're in it.

How to evaluate a quote

When you compare two installer quotes, look at:

1. Are all the standard inclusions listed individually? A quote that just says "complete install $9,500" is hiding what's not included.
2. Are adders called out explicitly with conditions? A good installer says "if your panel is full, panel upgrade is +$2,500" — not "additional charges may apply if conditions require."
3. Is the unit make, model, and kW size specified? A quote that says "20kW Generac" without the model number gives the installer flexibility to substitute.
4. Is the warranty path documented? Who handles warranty claims? What's the response time commitment?
5. What's the install timeline commitment? Specifically: from contract signing, when does install happen?

A good installer — local or otherwise — answers all five clearly in writing. If the answers are vague, the install will be vague.
