An outdoor kitchen is three trades wearing one coat: a gas job, an electrical job, and a cabinetry or masonry job. Almost everything that drives the cost and the timeline happens before the grill ever shows up.
We don't install. We sell the equipment, and we'd rather you understand the job well enough to judge a quote than find out afterwards. Codes vary by city and county — treat everything here as what to ask about, not as approval to build.
Start with the appliance list, not the layout
Every cutout dimension, clearance and gas requirement comes from the appliances you pick. Choose the grill, the side burner, the refrigeration and the ventilation first, get the manufacturer's installation sheets, and design the island to those numbers. Designing the island first and then shopping for appliances that fit it is the single most expensive mistake in this category.
Gas is the part people underestimate
Gas line size is set by the total connected BTU load of everything on the line and the length of the run — commonly somewhere between a half inch and an inch and a quarter, but that is a calculation, not a guess. The line needs an accessible shutoff and regulator, and it has to pass a pressure test before anything is covered or connected. Buried runs have a minimum cover depth and often a tracer wire.
This is licensed work in most places, and it is not the same trade as landscaping. If your landscaper is building the island, ask who is doing the gas.
Electrical
Outdoor receptacles need GFCI protection, and outdoor devices need to be wet-rated with in-use covers — the bubble covers that close over a plugged-in cord, not the flat ones. Refrigeration and any electric heating want dedicated circuits rather than sharing with the rest of the patio. If you are adding a powered hood, that is often a third trade permit.
Clearance to combustibles — the spec that ruins finished islands
Every built-in grill has a published clearance-to-combustibles requirement, and it is specific to that model. A wood-framed island is combustible construction. Most premium brands sell a factory insulating jacket or liner that makes installation into such an island possible — and without it, that installation is not code-compliant no matter how good it looks.
Get the clearance figures and the jacket part number off the manufacturer's sheet before the island is framed. Discovering this after the stone is on is the expensive version.
Ventilation only matters if you are covered
Fully open-air kitchens generally do not need a hood. Under a roof, a solid pergola, or any enclosure, they usually do, and the extraction rating scales with the total BTU load of the appliances beneath it. A hood should be wider than the grill — commonly three to six inches past each side — and mounted at the height the manufacturer specifies, typically around 30 to 36 inches above the cooking surface.
Permits, and who pulls them
Expect separate trade permits for gas and electrical, a mechanical permit if there is a powered hood, and often a building permit if the island is fixed, sits on footings, or attaches to the house. A contractor should pull these, not you. If a bidder suggests skipping permits, that tells you what you need to know about the rest of their work.
It arrives on a pallet, and you should inspect it before you sign
Outdoor kitchen components ship freight, not parcel. Someone has to be there, the delivery usually needs a liftgate, and the driver is not going to carry it into your yard.
Inspect it before you sign for it. Photograph anything damaged and refuse the delivery rather than accepting it — once you have signed clean, a damage claim gets much harder for everyone, including us. We will tell you this again on your order confirmation, because it is the single thing that most often goes wrong.
The sequence
- Pick the appliances and collect their spec sheets
- Design the island to those cutouts and clearances
- Permits pulled
- Gas and electrical rough-in, then the pressure test
- Island built
- Appliances set, with insulating jackets where required
- Final inspection
Questions to ask before you hire anyone
- Who is doing the gas work, and are they licensed for it? If it is a subcontractor, can I meet them?
- Are you pulling the permits, or am I?
- Will you install equipment I bought elsewhere? Ask this first — many contractors will not, because they cannot warranty it and they lose the markup.
- Have you installed this brand before? Can you show me the clearance spec you are building to?
- Who receives the freight delivery, and who is responsible if something arrives damaged?
- What does the quote exclude? Gas run length, trenching through existing hardscape, and electrical panel capacity are the usual surprises.
What drives the cost
We will not quote you a national average, because the only number that matters is yours. The things that actually move it: how far the gas and electrical have to run from the house, whether that run crosses existing hardscape, whether your panel has capacity, how many appliances share the gas line, whether the island is masonry or a prefab frame, and whether the site is flat. Two identical appliance lists can differ by a multiple depending on those answers.
