Compliance Calendar
NYC building compliance • October 2026 through December 2027
Reviewed October 8, 2026. Use this planning calendar alongside your building’s equipment, occupancy, and filing history. A date applies only when the property is covered.
How to use this calendar
Confirmed dates and standing requirements are separated from 2027 items still awaiting agency confirmation. Baseline dates are planning targets, not confirmation of a weekend or holiday extension. Check current agency instructions and any property-specific approvals.
Inspection completion, report submission, defect correction, and agency acceptance can have separate deadlines. Keep each milestone in your building’s calendar.
