Quality control inspector

Skill Requirements

QC Inspector careers require foundational knowledge of building science concepts, including the ability to systematically collect, organize and analyze data, use computerized software, understand residential code and building standards and requirements, and write accurate and comprehensive technical reports.  Having solid knowledge of advanced diagnostic test equipment, installation procedures and tools is also important.  Computer and specialized software literacy skills are essential, and applied knowledge of mathematics, statistics and physics, and basic construction and insulation materials and techniques is also expected. These foundational technical skills may be developed through coursework and training in different engineering and engineering technology disciplines (especially mechanical, industrial, electronics and environmental engineering) and through on-the-job and formal training in the specific technology tools, software and inspection procedures used by inspectors.

Interests and Traits

Residential QC inspectors typically have an interest in building systems and the interaction of various sub-systems (plumbing, electrical, HVAC) in residential environments. They are usually analytical, detail-oriented and organized, and like working in structured settings. They often work alone, however inspectors must also be good interpersonal communicators and enjoy working directly with others; much of their time is spent working directly with other professionals in the field, investigating, writing and communicating their findings and requirements through formal written reports and verbally. Although inspection work includes data analysis and writing tasks done in office environments, much of the work happens on-site and includes physical tasks, including the use of specialized equipment, ladders and common tools, often in tight spaces. The job requires good critical thinking, problem solving and deductive reasoning skills, working persistently and methodically using their findings to confirm that renovation and weatherization measures have been installed properly and meet industry and local code requirements.

Education and Training

QC Inspector careers have entry points at many different levels of education and experience, but for most employers 3 or more years of related experience (esp. HVAC, building design, construction and renovation methods) and some college, a two-year degree or completion of an apprenticeship in a technical-vocational area or trade is usually preferred.  Industry certifications such as BPI Building Analyst, Energy Auditor, or the RESNET-HERS Rater certification gives job seekers a competitive advantage; for some employers these or related certifications are expected or required. Most employers require QCIs to have the Home Energy Professional (HEP) Quality Control Inspector certification, which is supported by the U.S. Department of Energy and the National Renewable Energy Laboratory. This certification, which is designed specifically for the residential building industry, means that you can verify the compliance of retrofit work performed based on work plans and standards. It also confirms that you have the ability and skills needed to conduct audits and inspections using diagnostic equipment, and produce reports that specify corrective actions to achieve whole house performance.
