If OP's lease required e.g. a 60 day notice (and they pretty much all do!) that isn't true at all! That's confirmed by the OTA doc that was previously linked.

> The law is somewhat different for a tenant who wishes to move out upon the expiration of the written lease term, i.e., before the tenancy becomes month-to month. In that instance, the lease may require more than 30 days-notice of a tenant’s intent to vacate, but only if the lease also entitles the tenant to a written notice of a rent increase that is at least 15 days longer than that. For example, if the lease requires the tenant to provide a 60-day notice of intent to vacate, the lease must also entitle the tenant to a 75-day notice of a rent increase. If the lease fails to do so, the tenant is only required to give the housing provider a 30-day notice of intent to vacate.
