OCC Tier-1 Deployment: City of Vancouver Building Permits (2018–2025)

Description This dataset provides a complete Tier-1 empirical deployment of the Operator Closure Constraint (OCC) framework, analyzing building permit issuance in the City of Vancouver, British Columbia from 2018 to 2025. Purpose: To demonstrate that the OCC framework correctly identifies a sustainable administrative regime—one where durable closures keep pace with arrivals (DCR ≥ 1) and unresolved stock declines over time. Domain: Building permit issuance by the City of Vancouver. Each permit application constitutes a case unit; arrival occurs at permit number creation, closure occurs at permit issuance. Key Findings: 40,050 permit applications processed over the observation window Average Durable Clearance Ratio (DCR) of 1.04 at the 90-day horizon Unresolved stock declined from 494 cases to zero Regime classification: Sustainable Contents: Raw permit data (sourced from Vancouver Open Data Portal) Analysis script (Python) implementing OCC stock-flow calculations Derived time series with monthly arrivals, closures, stick rates, and DCR Diagnostic summary and regime classification Visualization figures Reproducibility artifacts (checksums, manifest, run log) Methodology: The analysis computes monthly arrivals and closures, derives durable closure metrics at 30, 90, and 180-day horizons, and tracks unresolved stock using the OCC stock-flow identity. With no appeal channel recorded in the source data, stick rates are conservatively set to 1.0. Limitations: This is a Tier-0/1 analysis measuring administrative closure (permit issuance), not downstream outcomes such as construction completion, inspection passage, or long-term code compliance.
