No. Building Inspectors do not require a four-year college degree. The standard credential is a journeyman license earned through a paid apprenticeship registered with the U.S. Department of Labor at https://www.apprenticeship.gov/. Some workers complete a 1- or 2-year certificate at a community or trade college before applying — but the journeyman license is what employers actually require.
Building Inspector apprentices typically start at $63,230 per year (10th percentile) and progress upward each year of the apprenticeship. By year 2, pay usually reaches the 50th percentile around $75,182. All training is paid — apprentices are W-2 employees of contractors or unions, not students paying tuition.
Common building inspector certifications include: ICC Building Inspector certification; State building inspector license; ICC Plans Examiner certification; OSHA 10/30-Hour. Most states also require a journeyman license; some have a separate master license for independent work.
