A health or code enforcement officer may now designate a building as substandard and uninhabitable for visible and substantial mold growth.

Landlords are not required to abate a mold infestation until they have notice of:

  • the infestation’s existence; or
  • the tenant’s violation of their obligation to keep the rented premises clean and sanitary.

Landlords are required to provide reasonable notice in writing to tenants of their intent to enter the premises to abate mold. [See RPI Form 567]
