Healthy Homes Specialist Credential
An Offer for ASHI Members

Because home inspectors are on the front line when it comes to evaluating the integrity of the home environment, it makes sense for ASHI to become involved in promoting a unique credential to its members.

ASHI, the National Environmental Health Association (NEHA) and The National Center for Healthy Housing (NCHH) are working together to offer the Healthy Homes Specialist (HHS) credential to ASHI members to ensure they are part of a knowledgeable workforce assisting the public in its growing concern over the issue of healthy homes.  The HHS credential can be used to help ASHI members expand the services they provide.  The Healthy Homes Specialist Credential is designed for health and housing professionals in the public, private and non-profit sectors. 


Use and Implementation
A variety of professionals may be interested in the Healthy Homes Specialist credential. As a member of ASHI you may use the Healthy Homes Specialist credential to expand the services you provide.

  1. Individuals who have been certified or licensed as lead risk assessors, radon measurement professionals, or mold professionals. These individuals have developed a basic expertise in a specific environmental hazard in the home and should be interested in expanding their capabilities and services.

  2. NEHA Registered Environmental Health Specialists seeking to document their experience and expertise in housing.
