HPD Compliance Operating System
A complete compliance management platform for NYC HPD violations - eliminating deadline surprises, scattered documents, and coordination chaos across 300+ buildings.
The pain
Missed certification windows → higher fees
No automated deadline tracking meant violations slipped past certification dates, triggering escalation and additional penalties.
No single source of truth
Case details lived across emails, PDFs, spreadsheets, and portal screenshots-leading to lost context and duplicated effort.
Evidence scattered everywhere
Photos, invoices, access logs stored in WhatsApp, email attachments, and local drives. Certification packets took hours to compile manually.
Access coordination killed productivity
Scheduling inspections, managing tenant communication, and documenting 'no access' failures consumed excessive team time.
Portfolio-level triage was impossible
No visibility into which buildings needed urgent attention. Teams reacted to fires instead of preventing them.
Compliance Timeline Engine
Automated deadline calculation, SLA tracking, and escalation flags based on violation type and certification windows.
- - Rules-driven deadline computation
- - Email/SMS reminders (T-72h, T-24h, T-2h)
- - Urgency scoring & prioritization
Case OS + Unified Timeline
Single case file per building: all violations, tasks, documents, communications, inspections in one auditable timeline.
- - Event-sourced activity log
- - Full-text search + faceted filters
- - HPD data sync (daily ingestion)
Evidence Vault
Structured proof collection: photos, invoices, contractor attestations with before/after validation and tamper detection.
- - Required evidence checklists
- - Auto-timestamping + EXIF capture
- - One-click certification packet export
Access Orchestration
Tenant scheduling, automated reminders, 'no access' documentation workflows, and delivery tracking.
- - SMS/WhatsApp notification sequences
- - Tenant contact preference tracking
- - Calendar sync (Google/Outlook)
Portfolio Risk Dashboard
Real-time risk scoring across all buildings: severity + deadline proximity + repeat history + enforcement flags.
- - "Top 20 at-risk" live view
- - Blocked/stalled reason tracking
- - Trend analysis (buildings worsening)
Multi-tenant Architecture
Enterprise white-label ready: separate portals for inspectors, clients, and admins with role-based access control.
- - Subdomain per company
- - Granular RBAC (inspector/client/admin)
- - Activity audit logs
Portfolio-level risk dashboard with real-time prioritization
Portfolio dashboard showing 300+ buildings with risk scores, deadline proximity, and status distribution.
Unified case timeline-every event in chronological order
Violation lifecycle timeline showing all events: issuance, appointments, evidence uploads, status changes, certification.
Evidence vault with required proof checklists
Evidence checklist interface: required photos, contractor attestations, before/after validation status.
Mobile-first inspector portal for field operations
Inspector portal mobile view: schedule, access appointment details, upload evidence on-site.
Outcome
Missed certification deadlines since deployment
What changed
Compliance became predictable. The team went from reactive firefighting to proactive case management.
Portfolio visibility unlocked strategic decisions. Risk scoring showed which buildings needed attention first, enabling better resource allocation and client communication.
Documentation became defensible. Every closure is backed by structured proof-photos timestamped, contractors attested, access attempts logged. Disputes are resolved with evidence, not memory.
Operations scaled without adding chaos. New buildings onboard in minutes. Inspectors work from mobile. Clients see status updates in real-time. The system handles growth without breaking.
Built as a scalable, multi-tenant SaaS platform designed for reliability, auditability, and future regulatory expansion beyond HPD.
