Following the September 1, 1963 commencement of the Real Property Actions and Proceedings Law (RPAPL), New York commercial tenancies have continued to operate under a framework distinct from residential protections. While the HSTPA caps residential late fees at $50 or 5% of rent, commercial landlords have significant latitude to impose financial penalties for late payment, governed by the doctrine of liquidated damages rather than New York's civil usury statutes.

The Dual-Penalty Structure

Well-drafted New York commercial leases typically impose two types of financial penalties for late rent:

1. Flat Administrative Late Fee

A fixed dollar amount or a percentage of the monthly rent assessed immediately upon the expiration of a grace period.

  • Typical Structure: "If any installment of base rent or additional rent is not received within 5 days of its due date, Tenant shall pay a late charge equal to 5% of the overdue amount."
  • Courts generally uphold late fees of 3-5% as reasonable and enforceable.

2. Default Interest

In addition to the flat fee, overdue amounts accrue interest until paid in full.

  • Typical Rate: 12-18% per annum.
  • Liquidated Damages and the 25% Benchmark: New York courts have established that usury laws do not apply to lease late fees or default interest because these obligations are not "loans or forbearances" of money. Consequently, the 16% civil usury limit under GOL § 5-501 is legally inapplicable. However, the 25% criminal usury threshold under Penal Law § 190.40 serves as a public policy benchmark; fees or interest exceeding this rate may be struck down as unconscionable penalties.
  • Corporate Exception: Under NY General Obligations Law § 5-521, corporations are generally prohibited from interposing a defense of civil usury, though this is largely irrelevant to commercial leases as usury statutes do not govern lease defaults.

The "Additional Rent" Classification

A critical drafting point in New York commercial leases is to expressly define late fees and interest as "additional rent." Under RPAPL § 711(2), as amended by the HSTPA of 2019, a landlord must serve a written rent demand providing at least 14 days' notice before commencing a summary non-payment proceeding.

If these charges are classified as "additional rent" in the lease, the landlord can include them in the 14-day demand and use them as a basis for a summary proceeding. Without this classification, the landlord cannot recover them in a summary proceeding and must instead bring a separate plenary action for breach of contract, which is slower and more expensive.

Enforceability: Liquidated Damages vs. Penalties

As in all contract law, New York courts will void a late fee provision if it constitutes an unenforceable penalty rather than a reasonable estimate of the landlord's actual damages from late payment. To survive judicial scrutiny:

  • The late fee must be a reasonable estimate of the landlord's actual administrative costs and losses.
  • The fee should not be designed to punish the tenant.

Collection Costs and Legal Fees

New York commercial leases should include a clause requiring the defaulting tenant to pay all of the landlord's costs of collection, including:

  • Reasonable attorney's fees.
  • Court filing fees and process server costs.
  • Any fees charged by a collection agency.

Without this clause, the landlord may not be able to recover legal costs even if they win in court.
