Attic Pull-Down Ladders (Home Inspections)

Attic pull-down ladders, also called attic pull-down stairways, are collapsible ladders that are permanently attached to the attic floor. Occupants can use these ladders to access their attics Attic pull down ladder

without being required to carry a portable ladder.

Common Defects

Homeowners, not professional carpenters, usually install attic pull-down ladders. Evidence of this distinction can be observed in consistently shoddy and dangerous work that rarely meets safety standards. Some of the more common defective conditions observed by inspectors include:

cut bottom cord of structural truss. Often, homeowners will cut through a structural member in the field while installing a pull-down ladder, unknowingly weakening the structure. Structural members should not be modified in the field without an engineer’s approval;
fastened with improper nails or screws. Homeowners often use drywall or deck screws rather than the standard 16d penny nails or ¼” x 3” lag screws. Nails and screws that are intended for other purposes may have reduced shear strength and they may not support pull-down ladders;
fastened with an insufficient number of nails or screws. Manufacturers provide a certain number of nails with instructions that they all be used, and they probably do this for a good reason. Inspectors should be wary of “place nail here” notices that are nowhere near any nails;
lack of insulation. Hatches in many houses (especially older ones) are not likely to be weather-stripped and/or insulated. An uninsulated attic hatch allows air from the attic to flow freely into the home, which may cause the heating or cooling system to run overtime. An attic hatch cover box can be installed to increase energy savings;
loose mounting bolts. This condition is more often caused by age rather than installation, although improper installation will hasten the loosening process;
attic pull-down ladders are cut too short. Stairs should reach the floor;
attic pull-down ladders are cut too long. This causes pressure at the folding hinge, which can cause breakage;
improper or missing fasteners;
compromised fire barrier when installed in the garage;
attic ladder frame is not properly secured to the ceiling opening;
closed ladder is covered with debris, such as blown insulation or roofing material shed during roof work. Inspectors can place a sheet on the floor beneath the ladder to catch whatever debris may fall onto the floor; and
cracked steps. This defect is a problem with wooden ladders.
In sliding pull-down ladders, there is a potential for the ladder to slide down quickly without notice. Always pull the ladder down slowly and cautiously.

Safety tip for inspectors: Place an "InterNACHI Inspector at work!" stop sign nearby while mounting the ladder.

Relevant Codes

The 2009 edition of the International Building Code (IBC) and the 2006 edition of the International Residential Code (IRC) offer guidelines regarding attic access, although not specifically pull-down ladders. Still, the information might be of some interest to inspectors.

2009 IBC (Commercial Construction):

1209.2 Attic Spaces. An opening not less than 20 inches by 30 inches (559 mm by 762 mm) shall be provided to any attic area having a clear height of over 30 inches (762 mm). A 30-inch (762 mm) minimum clear headroom in the attic space shall be provided at or above the access opening.

2006 IRC (Residential Construction):

R807.1 Attic Access. Buildings with combustible ceiling or roof construction shall have an attic access opening to attic areas that exceed 30 square feet (2.8m squared) and have a vertical height of 30 inches (762 mm) or more. The rough-framed opening shall not be less than 22 inches by 30 inches, and shall be located in a hallway or 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.

Tips that inspectors can pass on to their clients:

Do not allow children to enter the attic through an attic access. The lanyard attached to the attic stairs should be short enough that children cannot reach it. Parents can also lock the attic ladder so that a key or combination is required to access it.
If possible, avoid carrying large loads into the attic. While properly installed stairways may safely support an adult man, they might fail if he is carrying, for instance, a bag full of bowling balls. Such trips can be split up to reduce the weight load.
Replace an old, rickety wooden ladder with a new one. Newer aluminum models are often lightweight, sturdy and easy to install.

In summary, attic pull-down ladders are prone to a number of defects, most of which are due to improper installation.

Mold, Moisture and Your Home

Mold Basics

The key to mold control is moisture control.
If mold is a problem in your home, you should clean up the mold promptly and fix the water problem.
It is important to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth.

Why is mold growing in my home?

Molds are part of the natural environment. Outdoors, molds play a part in nature by breaking down dead organic matter, such as fallen leaves and dead trees. But indoors, mold growth should be avoided. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on surfaces that are wet. There are many types of mold, and none of them will grow without water or moisture.

Can mold cause health problems?

Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing. Molds have the potential to cause health problems. Molds produce allergens (substances that can cause allergic reactions), irritants and, in some cases, potentially toxic substances (mycotoxins). Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals. Allergic responses include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin rash (dermatitis). Allergic reactions to mold are common. They can be immediate or delayed. Molds can also cause asthma attacks in people with asthma who are allergic to mold. In addition, mold exposure can irritate the eyes, skin, nose, throat and lungs of both mold-allergic and non-allergic people. Symptoms other than the allergic and irritant types are not commonly reported as a result of inhaling mold. Research on mold and health effects is ongoing. This article provides a brief overview; it does not describe all potential health effects related to mold exposure. For more detailed information, consult a health professional. You may also wish to consult your state or local health department.
