I am inquiring about breaking a lease and in the lease agreement it has a section that states... "Tenant may terminate the tenancy by giving written notice to the landlord at least 30 days prior ro the intended termination date, subject to any applicable local laws, such notice may be given on any given date."
Does this mean I can give a 30 day notice with no penalty?

I'd appreciate any advice.

Correct. Like it says you must give at least 30 days written notice.

Yes, for example if it is a year lease, you will have to give a 30 day notice prior to the end of the lease, and after the end of the lease you will be required stlll to give a 30 day notice.

It does not mean you can give notice prior to the end of the lease date.
