What is an inspection in construction?

A construction inspection is a check of completed work by a building official, owner's representative, or the contractor's own team to confirm it meets code, the contract documents, and safety rules before the job moves on.

An inspection is a formal look at work in place to decide whether it passes. The word covers several different checks on a job. The best known is the building department inspection tied to a building permit, where an inspector from the authority having jurisdiction approves each stage before it gets covered up. But owners, lenders, insurers, and the contractor's own quality and safety staff inspect too.

The rule that matters most in the field is simple. Do not cover work that has not been inspected. Pour concrete over an uninspected footing or close a wall before rough-in sign-off, and the inspector can make you tear it out.

Main types of construction inspections

Who inspects what
TypeWho does itWhat it checks
Code inspectionsLocal building departmentFootings, framing, rough-in, insulation, final, per the permit
Special inspectionsThird-party inspectors hired per code or engineerStructural steel, welding, concrete strength, fireproofing
Owner or architect site visitsArchitect, owner's repConformance with drawings and specs, progress for payment
Lender draw inspectionsBank's inspectorPercent complete before releasing a construction draw
Quality control checksContractor's own staffWorkmanship before calling for outside inspections
Safety inspectionsContractor and OSHAHazards on site, equipment, fall protection

On the safety side, federal OSHA rules for construction require employer accident prevention programs that include frequent and regular inspections of job sites, materials, and equipment. OSHA itself can also show up for an enforcement inspection, which is a different event entirely; see how to prepare for an OSHA inspection.

How a code inspection works on a real job

Say an HVAC sub finishes ductwork and rough-in in a two-story house. The process usually runs like this:

  1. The foreman confirms the work is complete and matches the approved plans, with the permit card posted on site.
  2. The office calls or books the inspection through the city portal, often a day or more ahead.
  3. The inspector checks the work and either signs off or issues a correction notice listing the problems.
  4. If it fails, the crew fixes the items and the job is rescheduled for a re-inspection, which may carry a fee.
  5. Only after sign-off does the drywall sub close the walls.

One failed rough-in can push insulation, drywall, and everything after by several days. That is why the superintendent's look-ahead schedule should show inspection dates as tasks, not afterthoughts.

Common mistakes and disputes

  • Calling for inspection before the work is ready, which wastes the slot and annoys the inspector.
  • Covering work early to save a day, then paying for demolition and rework.
  • No photos. Pictures of rough-in before cover-up settle many later disputes about what was installed.
  • Arguing code interpretation in the field. Ask for the code section and escalate through the building official if needed.
  • Losing track of special inspection reports, which can delay the certificate of occupancy.

Frequently asked questions

Who schedules a building inspection?

Usually the permit holder, which is the general contractor or the trade contractor who pulled the permit. Many jurisdictions now take requests online.

What happens if I fail an inspection?

The inspector issues a correction list. You fix the items and request a re-inspection. Some jurisdictions charge a re-inspection fee.

What is a special inspection?

An inspection by a qualified third party, required by the building code or the engineer of record, for critical items like structural welding or concrete strength.

Is an OSHA inspection the same as a building inspection?

No. Building inspections check code compliance of the work. OSHA inspections check worker safety and can lead to citations and penalties.
