Dropping a grill into an opening that already fits is a morning's work. Building the opening is a masonry job. This calculator prices both, plus the gas run and the electrical, using the figures published for Santee.
Most of the money in a built-in grill installation is decided before anyone touches a grill: whether the cut-out already exists, whether it is the right size, and how far the gas has to travel. Published figures put a same-size swap at $800–$2,000 and a cut-out resize at $1,500–$4,000 for essentially the same appliance. This calculator asks about the opening first for that reason.
The biggest fork in the road. A same-size swap runs $800–$2,000 published; resizing the opening for a different model runs $1,500–$4,000. The cost is not the cutting — it is putting the face back so the repair does not read as a patch.
Published figures put an entry-to-mid 30–36 inch built-in at $1,500–$4,000 and a high-end 36–42 inch at $4,000–$9,000 or more. At the top end you are buying burner construction, 304 stainless and parts availability rather than square inches.
Published at $500–$1,800 for a new line. Distance matters, but what really moves it is what the trench has to cross: lawn is cheap, pavers get lifted and relaid, and stamped or coloured concrete leaves a patch that is visible forever.
$250–$700 published for a hookup. Electronic ignition usually runs on a battery, but rotisserie motors, interior lights and any refrigeration do not.
Not a cost question first — a safety one. Under a solid roof or soffit, a vent hood stops being an upgrade. Published guidance for high-BTU suites points at roughly 1,200–2,000 CFM at about 30–36 inches above the cook surface.
With no structure to build into, the job is really a BBQ island build, and it prices like one.
This calculator works from the 2026 cost figures published for Santee and East County San Diego. What it cannot see is your slab, the capacity of your gas meter, what is under the old patio, or how a crew would get block and a stone slab into your back yard — and those are exactly the things that decide a real price. We will come out, measure, and give you a written scope with no pressure attached.

The grill itself is separate: $1,500–$4,000 for an entry-to-mid 30–36 inch unit, $4,000–$9,000 or more for a high-end 36–42 inch.
Measure the opening, not the old grill. Manufacturers quote nominal sizes — a '32 inch' grill from two brands can have cut-out requirements that differ by more than an inch, and an inch is the difference between a morning's work and a masonry job. Every manufacturer publishes an exact cut-out dimension in the installation manual; that is the number to match.
Sometimes, and only with the manufacturer's own conversion kit. Natural gas runs at a lower pressure and needs larger burner orifices to deliver the same heat, so the jets and often the regulator have to be changed. Not every model has a kit available — check before committing to the trench. Converting any other way gives you a grill that either will not reach temperature or runs rich and sooty.
For the grill itself, no. For a new gas line, yes — the City of Santee requires a plumbing permit for new piping, and gas piping has to be sized from the California Plumbing Code fuel-gas tables and pressure tested before the trench is covered. A new electrical circuit needs an electrical permit. A propane tank in the island with no new wiring typically needs neither. Confirm with Santee Planning & Building.
In the open air, no. Under a solid roof, soffit or enclosed patio cover, yes — grease and combustion products collect against the ceiling, which is both a fire risk and the item most likely to be flagged at inspection. Under an open pergola or louvered cover there is normally enough air movement. The island itself also needs vent openings in the enclosure so that gas cannot collect underneath the grill.
A same-size swap is usually a few hours. A new cut-out in an existing island is a day or two, plus finish repair. A new gas run adds the permit, the trench and a pressure test that has to happen before the trench is backfilled — if the trench gets closed before the inspector sees it, it gets opened again, so it is worth confirming the inspection is booked before the crew starts filling.
