What is the minimum size for passageways through attics or crawlspaces to access appliances?

The minimum size for passageways through attics or crawlspaces to access appliances is 24"x30". This dimension ensures that there is sufficient space for a technician to safely navigate and access appliances for maintenance, inspection, or repairs. Adequate passageway sizes are critical in reducing the risk of accidents and ensuring that the technician can maneuver tools and equipment effectively.

The specified size aligns with industry standards that prioritize safety and accessibility, making it vital for both the installation and servicing of various mechanical systems. Smaller passageways may hinder access, making it difficult to perform necessary tasks, which can lead to unsafe working conditions or inadequate service of the appliances.
