Non-Scope Considerations of ASTM E1527-13

By Kevin Taylor, Senior Vice President

ASTM Standard
Non-Scope Considerations are not included as part of the Scope of Work of the ASTM E1527-13 standard, but can be included in the Phase I Report at the request of the report users. Some of the most common non-scope considerations described in the Standard are summarized in this article; and additional non-scope items can also be included. Non-scope considerations can impact the health of the building occupants; development of the property; and future legal risks. As such, non-scope considerations can pose additional risks and impact the value of the property.

Asbestos Containing Materials (ACMs)

Asbestos is a naturally occurring mineral fiber that was used in many types of building materials. Asbestos becomes a health risk if the fibers become airborne.


Radon is a radioactive, colorless, odorless and tasteless gas produced by the decay of uranium or thorium.

Lead-based Paint (LBP)

Lead was used in oil-based paints until the late 1970s.  Lead-based paint becomes a health risk if  the paint dust becomes airborne.

Lead in Drinking Water (LWI)

Lead can be found in drinking water due to the leaching from the plumbing system.

Indoor Air Quality  (IAQ)

There are many potential sources of indoor air pollution such as building materials cleaning chemicals and/or pesticides.


Mold is found almost everywhere in indoor and outdoor environments.  Molds grow with an organic food source and moisture.


A wetland is an area that is saturated with water that supports aquatic vegetation and/or aquatic animals.

Endangered Species Act (ESA)

The ESA protects endangered and threatened plant and animal species.

Regulatory Requirements – Depending in the usage of the property non-compliance with environmental laws could represent a risk to the property.
