Full Breakdown
Code § 285-36(O)(7), enacted by Local Law No. 2-2026 (adopted April 8, 2026), sets a minimum one-year rental term for every ADU in Town: property owners cannot lease an ADU for less than a one-year term. If the lease is breached or ends before the year is up, the owner is barred from assigning the remainder of the term to a replacement tenant, closing off short-term or rotating-tenant use of the unit. The restriction ties into the broader permit-transfer scheme in § 285-36(O)(14): if the property with the ADU is sold, an existing tenant renting under the prior owner's lease may stay through the end of the current lease term, capped at 12 months, and must receive at least 90 days' notice if the new owner intends to discontinue the ADU's use for rental purposes.
That notice requirement must itself be written into the lease agreement given to the tenant. Together these provisions steer Greenburgh's ADU stock toward stable, longer-term occupancy rather than short-term or vacation rentals, consistent with the Town's owner-occupancy and single-family-character goals for the program.
Violations & Fines
Leasing an ADU for under a year, or assigning a broken lease's remaining term to a new tenant, is a violation of § 285-36(O) subject to revocation of the ADU special permit and a fine of not less than $1,000 under § 285-36(O)(19). Owners must also certify compliance annually by January 10 via sworn affidavit to the Building Inspector.
