Can my landlord enter my apartment without notice?

No — outside a genuine emergency, you have the right to advance notice in nearly every U.S. jurisdiction.

Most states require 24 to 48 hours notice for non-emergency entry, with emergencies as the narrow exception. The exact notice period is set by your state's statute.

Send your landlord written notice asserting your right to advance notice under your state's entry statute, and document every entry that occurs without it.
