Kitchen Planning Guideline 22—Microwave Landing Area
Recommended: Provide at least a 15-inch landing area above, below, or adjacent to the handle side of a microwave oven.

Kitchen Planning Guideline 23—Oven Landing Area
Recommended: Include at least a 15-inch landing area next to or above the oven.

At least a 15-inch landing area that is not more than 48 inches across from the oven is acceptable if the appliance does not open into a walkway.

Kitchen Planning Guideline 24—Combining Landing Areas
Recommended: If two landing areas are adjacent to one another, determine a new minimum for the two adjoining spaces by taking the longer of the two landing area requirements and adding 12 inches.

Kitchen Planning Guideline 25—Countertop Space
Recommended: A total of 158 inches of countertop frontage, 24 inches deep, with at least 15 inches of clearance above, is needed to accommodate all uses, including landing area, preparation/work area, and storage.

Built-in appliance garages extending to the countertop can be counted towards the total countertop frontage recommendation, but they may interfere with the landing areas.

Kitchen Planning Guideline 26—Countertop Edges
Recommendation: Specify clipped or round corners rather than sharp edges on all counters.
