Every range and cooktop guide carries a clearance diagram showing the minimum space between the cooking surface and the cabinets above, and between the range and any wall or cabinet beside it. Heat and flames rise from the burners, and wood cabinets and walls are combustible.
These rules come up constantly in San Diego kitchens. Small galley kitchens in 1950s Clairemont tract homes and older Craftsman bungalows in North Park and South Park were laid out around narrow ranges and low cabinets. When owners upgrade to a wider or professional-style range, or remodel cabinets, the clearances change quietly.
What the guides say
- •Amana AGR4230BA (30-inch gas range): A 30-inch minimum between the top of the cooking platform and the bottom of an uncovered wood or metal cabinet, or 24 inches when the cabinet bottom is covered with the specified flame-retardant millboard and sheet metal. It lists a 13-inch maximum depth for upper cabinets, 18 inches minimum from upper side cabinets to the countertop, and 2 inches minimum of countertop space to a side wall or other combustible material.
- •Amana AEP222VA (20-inch electric range): The overhead figures are the same, but the side figure is larger: 5 inches minimum of countertop space to a side wall or other combustible material. It adds that if cabinets above the surface units are used for storage, a range hood projecting at least 5 inches beyond the cabinet bottoms should be installed.
- •Whirlpool GCI3061X (30-inch induction cooktop): It repeats the 30-inch and 24-inch overhead rule and a 1-inch minimum to the nearest combustible surface on either side above the cooktop. Where a range hood or microwave hood sits above, it says to follow that product's installation instructions instead.
The overhead rule is consistent. Side clearance changes from model to model, so it's the figure to check most carefully.
Why each rule exists
- •Rising heat. Cabinets directly over burners take the most heat. The 30-inch distance keeps their surface from getting hot enough to scorch or ignite during normal cooking.
- •Protection allows less space. Fire-resistant board and metal on the cabinet bottom is why 24 inches is allowed instead of 30.
- •Reaching over burners. Storage above the cooktop means reaching across heat, hence the Amana guide's hood recommendation.
- •Side heat. Burners near the range edge heat the wall or cabinet beside them. Larger burners generally need more room.
- •Cabinet depth. Limiting upper cabinets beside the range to 13 inches keeps them from overhanging the cooking area.
Where this comes up in San Diego kitchens
- •Range against a side wall. Common in galley kitchens and condo kitchens Downtown and in Hillcrest. A 2-inch side clearance on one model can become 5 inches on another.
- •Pro-style upgrades. Owners in La Jolla, Del Mar and Coronado who swap a 30-inch range for a 36-inch or 48-inch professional range need that range's own clearances, which are often larger. Brands like Wolf and Viking publish their own diagrams.
- •Microwave above the range. The microwave's guide replaces the cabinet clearance; see over-the-range microwave mounting height.
- •Rental turnover. In rental-heavy areas like Pacific Beach and University City, replacement ranges are sometimes chosen on price and width alone. Check the side figure before it's delivered.
How to measure
- Measure from the cooking surface (grates or glass top) straight up to the underside of the cabinet or hood above.
- Check whether that cabinet bottom has any fire-resistant covering. If not, use the 30-inch figure.
- Measure from the edge of the range to the nearest side wall, tall cabinet or other combustible surface above countertop height.
- Measure from the countertop to the bottom of the upper cabinets on each side.
- Measure the depth of the upper cabinets beside the range.
- If a microwave or hood sits above, find its guide, which sets the clearance in its place.
What goes wrong
- •Cabinet finishes scorch, blister or discolor above and beside the burners.
- •Hot cabinets and walls raise fire risk during high-heat cooking.
- •Handles and knobs on nearby cabinets get hot.
- •A wider replacement range quietly shrinks the side clearance.
What we check on a service visit
If cabinets get hot even at correct distances, we look for a burner running too high, a misadjusted air shutter or the wrong orifices on a gas range, a stuck-on element or failed switch on an electric range, and on ranges with oven vents, whether the vent is blocked. See our range repair page.
Work for other trades
- •Raising, removing or covering upper cabinets is work for a cabinet installer or contractor. Ask your building department about permits for a remodel.
- •Moving the range may need a new outlet from a licensed electrician, or a moved gas line from a licensed plumber.
- •Adding a hood may need a circuit and ductwork; see range hood mounting height.
