A NYC landlord compliance calendar should combine fixed government filing windows with building-specific work. Start with the dates below, confirm that each requirement applies to your property, and add the exact dates shown on leases, notices, permits, insurance documents, and violations. Official instructions control when they differ from a reminder.
January through March: review the year ahead
Start the year with the review below. This is also a good time to apply the filing habits in 7 Ways NYC Landlords Can Stay Organized .
- List every apartment, current lease end date, and renewal workflow
- Review open maintenance requests, violations, and contractor follow-up
- Schedule required inspections and recurring building-system service
- For buildings covered by Local Law 55, organize the annual indoor-allergen inspection process and required notices
- Confirm insurance renewal dates and emergency contacts
April through July: HCR annual rent registration
HCR says owners of rent-stabilized buildings must submit an annual registration for each stabilized apartment between April 1 and July 31. Initial registration rules are separate. Keep the submitted data, confirmation, supporting leases, and rent records together.
If you have affected units, also organize renewals for the 0% guideline period described in The NYC Rent Freeze: What Landlords Need to Organize .
By September 1: HPD property registration
HPD states that the annual property-registration deadline is September 1 for properties required to register. HPD registration is separate from HCR rent registration. Track preparation, signatures, the fee, mailing or submission, and acceptance confirmation as separate steps.
October through May: heat season
NYC heat season runs from October 1 through May 31. HPD states that apartments must be at least 68°F from 6 a.m. to 10 p.m. when the outside temperature is below 55°F, and at least 62°F overnight regardless of outside temperature. Hot water must be available year-round at a constant minimum of 120°F.
Before October, service heating equipment, confirm responsible contacts, and review the response plan for resident reports. Use the NYC Heat Season Checklist for Landlords: 2026–27 to organize the building review and the new January 2027 steam-radiator workflow.
Every month: run a short property review
For each property, check the work below. Record who owns each task and the next action. Do not mark an agency matter complete only because repair work finished; confirm required certification or closure.
- Open repairs and resident messages
- New or unresolved violations
- Upcoming lease and notice dates
- Expiring insurance, permits, or vendor documents
- Changes published by the agencies that govern the building
Keep the calendar connected to the record
EstatesCheck can organize calendar reminders alongside leases, maintenance history, documents, fines, and violation records. A small landlord can then review upcoming work by property while still confirming requirements through official sources.
