Most leases will have an entry provision that details when the landlord can enter the property.1 However, just because something is stated in the lease doesn’t mean it’s legally binding. Even though a lease is a legal document, the conditions stated in it still have to follow the law.
For example, a lease for a home in Arizona may say the landlord can enter the property at any time without notice. But because Arizona law requires the landlord give two days’ notice, this portion of the lease would not be legal or enforceable.2
If your lease doesn’t have an entry provision or mention anything about when the landlord can enter, your state’s privacy laws still apply.
If you think your rights have been violated, a court will refer to your implied right to quiet enjoyment—a concept of common law that "refers to the right of an occupant of real property, particularly of a residence, to enjoy and use premises in peace and without interference," according to USLegal.4
Even if it is not in your lease or rental agreement, a court will still recognize this right.
Part of this covenant protects your privacy as outlined in your state’s laws. For example, in California, the law states that a landlord must provide written notice before entering your property. If they don't, they are in violation of your lease, oral or written.5
