Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Depending on your state, a home inspector may need a license. All states and the District of Columbia require home inspectors to undergo training. However, some states (such as New York, Texas, Washington, and Illinois) require state-issued licenses while others (including California, Colorado, Pennsylvania, and Virginia) do not.

Other professional certifications include the American Society of Home Inspectors (ASHI) certification, the International Association of Certified Home Inspectors (InterNACHI) certification, and the National Home Inspector Examination. Inspectors can also receive certifications in specialized areas. These can include structural specialties, like chimneys, swimming pools, or septic systems, as well as specific issues like mold, pests, or radon gas. Whatever your situation, make sure your home inspector is certified to handle it.

Certified fire door inspectors should inspect fire doors. These professionals receive training to specifically assess the condition, functionality, and compliance of fire doors. They often hold credentials from groups like the Door and Hardware Institute (DHI) or the International Fire Door Inspector Association (IFDIA). While fire marshals won’t usually do hands-on inspections, they’ll check that doors are being maintained properly during routine safety audits. If a building relies on fire doors for code compliance, it needs someone who understands the details—the difference between a cosmetic issue and a safety failure—and standards to sign off with confidence.

At a minimum, landlords typically perform an apartment home inspection before tenants move in and after they move out. Most lease agreements include a “right to entry” clause allowing for “inspection by the landlord.” They do this to check for damage, identify repairs and maintenance needs, and ensure tenants are following property rules.
