What is a Certificate of Occupancy?
A certificate of occupancy is an official document issued by a municipal authority confirming that a building complies with applicable codes and is safe for occupancy.
Why a Certificate of Occupancy Matters in Real Estate
In Canadian construction and real estate, a certificate of occupancy is required before a new building or major renovation can be legally inhabited.
It confirms:
- Completion of inspections (e.g., fire, plumbing, electrical)
- Compliance with building codes and permits
- Safety and habitability
Understanding this certificate helps buyers, builders, and landlords ensure compliance and avoid legal issues.
Example of a Certificate of Occupancy in Action
The developer secured the certificate of occupancy before residents moved into the newly constructed apartment building.
