Shopping for a BBQ stove for sale usually starts with one simple question: gas, charcoal, or something else? 

That question matters less than most buyers think. The bigger factors are how you actually cook, how much space you have, and what kind of maintenance you’re willing to keep up with over the years. Get those right first, and the fuel type decision tends to fall into place on its own.

This post breaks down the practical side of the purchase, from fuel type and sizing to installation requirements and the details that separate a grill that lasts a decade from one that needs replacing in three years.

Fuel Type: The First Real Decision

Every BBQ stove for sale falls into one of a few fuel categories, and each one changes how you cook and how much upkeep is involved.

• Gas (natural gas or propane) heats fast and gives precise temperature control, making it the most common choice for everyday grilling. Natural gas connects to a home gas line and never runs out mid-cook, though the line installation should be handled by a licensed professional and permitted through your local Authority Having Jurisdiction (AHJ). Propane uses refillable tanks, which simplifies installation but means keeping a spare tank on hand.
• Charcoal delivers a smokier flavor gas can’t fully replicate, but it takes longer to heat and requires more cleanup.
• Pellet grills run on wood pellets and land in the middle: more flavor depth than gas, less hands-on work than charcoal, though they need electricity to run the auger and temperature controller.

None of these is objectively better. A weeknight griller who wants speed usually leans gas. A weekend cook who values flavor over convenience often prefers charcoal or pellet.

Sizing: Match the Grill to How You Actually Cook

Grill size is usually measured by cooking surface area, and it’s easy to overbuy. A large grill sitting mostly empty wastes fuel and heats unevenly, since burners are spaced for a bigger surface than what’s being used.

A rough starting guide:

Household Size	Typical Cooking Surface	Notes
1-2 people	Around 300-350 sq in	Enough for regular weeknight cooking
3-5 people	Around 400-500 sq in	Common mid-size range for families
6+ people or frequent entertaining	600+ sq in	Worth considering multi-zone burners

Treat these numbers as general starting points, not fixed rules. Actual needs vary based on how often you host larger groups and whether you cook multiple items at once.

Installation and Clearance Requirements

This is where a lot of buyers run into trouble after the purchase, especially with built-in or island-style units. Any gas-fired grill installed near a structure needs to meet clearance-to-combustibles requirements, set by the manufacturer’s installation manual and referenced in codes like NFPA 54 (the National Fuel Gas Code) and the local International Fuel Gas Code (IFGC) or International Residential Code (IRC) as adopted by your jurisdiction.

A few points worth confirming before you buy:

1. Check whether the unit is certified to ANSI Z21 (for gas grills) or the applicable CSA standard, since this is what most local inspectors and AHJs check for during permitting.
2. Confirm minimum clearance distances to walls, railings, and overhangs directly from the manufacturer’s spec sheet. These figures vary by model and shouldn’t be assumed based on a similar-looking grill.
3. For natural gas units, plan for a licensed installer to handle the gas line connection and any required permit, rather than treating it as a DIY project.

For contractors and installers: if you’re specifying a BBQ stove for sale as part of a client’s outdoor kitchen build, confirm the manufacturer’s warranty terms before installation. Some warranties are voided if the unit isn’t installed within the specified clearance and ventilation requirements, so it’s worth documenting compliance at the time of install rather than after an issue comes up.

Materials That Affect Long-Term Durability

The grill body and cooking grates take the most wear, so material choice has a real effect on how long the unit lasts outdoors.

• Stainless steel, especially higher grades like 304-grade, resists rust well, though it can still develop surface staining without occasional cleaning.
• Porcelain-coated cast iron grates hold heat well and clean up easily, but the coating can chip if scraped aggressively, exposing the metal underneath to rust.
• Cast aluminum housings resist corrosion and cost less than stainless, though they dent more easily.

Frequently Asked Questions

Do I need a permit to install a gas grill that runs on natural gas? 

In most jurisdictions, yes. A natural gas connection typically requires a permit and inspection under codes adopted from the IFGC or IRC. Requirements vary by city and county, so it’s worth checking with your local building department or AHJ before installation begins.

How long does a typical gas grill last? 

With regular cleaning and proper clearance during installation, many gas grills last eight to fifteen years, though burner and grate replacement is common maintenance along the way. Actual lifespan depends heavily on climate, usage frequency, and material quality, so treat this as general guidance rather than a guarantee.

Is charcoal or gas better for a backyard grill? 

Neither is universally better. Gas offers faster heating and more consistent temperature control, which suits frequent, convenience-focused grilling. Charcoal takes longer and requires more cleanup but produces a smokier flavor that many grillers prefer for weekend cooking.

What’s the most common mistake buyers make when shopping for a BBQ stove for sale? 

Sizing the grill to the space available rather than to actual cooking habits is one of the most common missteps. A grill that’s too large for regular use burns fuel inefficiently and can develop uneven hot and cold zones, while one that’s too small limits what you can cook for larger gatherings.

Final Thoughts

The right grill for your backyard comes down to matching fuel type and size to how you actually cook, then confirming installation requirements against manufacturer specs and local code before anything gets installed. Skipping that last step is where most post-purchase problems start.
