According to the 2021 International Residential Code (IRC), buildings with an attic area greater than 30 square feet and a vertical height of 30 inches or more are required to have an access point to the attic.

The rough-framed opening shall be not less than 22 inches by 30 inches (559 mm by 762 mm) and shall be located in a hallway or other location with ready access. Where located in a wall, the opening shall be not less than 22 inches wide by 30 inches high (559 mm wide by 762 mm high).
A scuttle hole is an opening in the ceiling, or less commonly the wall, that provides access to the attic of a house.
The rough-framed opening shall not be less than 22 inches by 30 inches (559 mm by 762 mm) and shall be located in a hallway or other readily accessible location. A 30-inch (762 mm) minimum unobstructed headroom in the attic space shall be provided at some point above the access opening.
In attics with only a scuttle hole entrance, cables run across the face of rafters or studs must be protected with guard strips for a distance of 6 feet (1829 mm) from the entrance.
An attic needs at least one square foot of ventilation for every 300 square feet of attic space. That means the typical ratio of attic area to attic ventilation is 300:1. Half of your ventilation should be exhaust vents and half should be intake vents.
An attic access opening shall be provided to attic area that exceed 30 square feet and 2. that has a 30-inch minimum unobstructed headroom in the attic space. 3. Rough-framed opening shall not be less than 22 inches by 30 inches.
If your access panel will grant personnel entry – in other words, if a human being will need to crawl partially or completely through the opening – it must be at least 20 by 20 inches. If this is not possible, it should be large enough for cleaning and spaced at 12-foot intervals throughout the space.

A scuttle attic is an attic space accessed by a small hole in the ceiling. The hole, along with the panel that covers it, is called a hatch. Because the term ''scuttle attic'' refers to the opening rather than the attic itself, you might also see it called a ''scuttle hole'' or an ''attic hatch.
A simple attic hatch is the most common and widely-used attic door by homeowners. This can be seen as a removable part of the ceiling that is typically in the shape of a rectangle or square. Accessing the attic would entail the homeowner to just simply push up on this ceiling cut-out and move it to the side.
Space between the structural ceiling and the dropped ceiling or under a raised floor is typically considered plenum; however, some drop-ceiling designs create a tight seal that does not allow for airflow and therefore may not be considered a plenum air-handling space.
