Certificate of Occupancy Eligibility Calculator

Determines whether a building project meets the basic eligibility criteria for a Certificate of Occupancy (CO) based on inspection scores, outstanding violations, permit status, and compliance rates.

Final Inspection Score (0–100)

Number of Outstanding Violations

Number of Critical (Life-Safety) Violations

Total Permits Required

Permits Still Open / Not Finalized

Correction Compliance Rate (%) — items corrected vs. cited

Fire Department Clearance Obtained?

-- Select -- Yes No

Zoning / Planning Approval Obtained?

-- Select -- Yes No

#### Formulas Used

1. Permit Closure Rate (PCR)

PCR = ((Total Permits − Open Permits) / Total Permits) × 100

2. Eligibility Score (ES) — weighted composite

ES = 0.35 × Inspection Score + 0.25 × Compliance Rate (%) + 0.20 × PCR (%) + 0.10 × Fire Clearance (100 if Yes, 0 if No) + 0.10 × Zoning Approval (100 if Yes, 0 if No)

3. Hard-Stop Disqualifiers (any one triggers INELIGIBLE)

D1: Critical Violations > 0 D2: Inspection Score

4. Eligibility Determination

If any Disqualifier triggered → INELIGIBLE Else if ES ≥ 75 → ELIGIBLE Else if 60 ≤ ES
