You must provide your landlord with reasonable access to your apartment so the landlord can make repairs, inspections, improvements, etc. However, your landlord must give you 24 hours notice before accessing your apartment. If your landlord shows up unannounced, you have the right to refuse access and ask your landlord to come back at a more convenient time.
MSU's Student Legal Services program is managed by the Associated Students of Montana State University (ASMSU). Please thank your student government for prioritizing legal services for MSU students!
