Pre-Occupancy Testing & Certification

Final Checks Before a Building Goes Back Into Use

Before a building is occupied — whether it’s new construction, a renovation, or after environmental work — it’s important to confirm that conditions are safe and meet project or regulatory requirements.

Pre-occupancy testing is used to verify indoor air quality, environmental conditions, and any project-specific concerns before the space is turned over for use.

The goal is to provide clear confirmation that the space is ready, so there are no surprises after people move in.

• Verification of conditions following construction or renovation
• Post-remediation or post-abatement clearance testing
• Evaluation of ventilation and building systems, when applicable
