Generally revise residential landlord and tenant laws

This bill revises Montana's residential landlord and tenant laws by updating definitions and requiring a 90-day notice period for changes or termination of rental agreements entered into after one year with a property management company. The legislation directly affects landlords, tenants, and property management companies by clarifying terms such as "property management company," "good faith," and "dwelling unit" to ensure consistent application across the state. Key provisions include establishing what constitutes an emergency situation, defining guest stay limits, and specifying how rent and rental agreements are interpreted. These changes aim to provide clearer legal standards for residential leasing relationships without altering existing rights or obligations for either party.
