A Completion Certificate (CC) certifies that a building has been constructed according to the approved architectural plans and local building bylaws, whereas an Occupancy Certificate (OC) certifies that the building is safe, compliant, and legally fit for people to live in. [1, 2]
## Key Differences
* Purpose: Completion Certificate (CC) confirms structural and regulatory compliance with sanctioned plans. Occupancy Certificate (OC) confirms safety, habitability, and readiness for human residence. [2, 3, 4]
* Sequence: Completion Certificate (CC) is issued first once the physical construction phase ends. Occupancy Certificate (OC) is issued second only after the CC is granted and civic infrastructure is inspected. [1, 2]
* Civic Utilities: Completion Certificate (CC) does not guarantee active connections. Occupancy Certificate (OC) requires functional water, sanitation, electricity, and fire safety systems before issuance. [2, 3, 5]
* Legal Rights: Completion Certificate (CC) proves the building is built right. Occupancy Certificate (OC) grants the legal right to occupy the property, register it, and obtain permanent utility connections and home loans. [1, 2, 5, 6]
