also applies to whether or not pets may be kept by the renter. On the other hand, the renter may also have specific rights against intrusions by the landlord (or other tenants), except under emergency circumstances. A renter is in possession of the property, and a landlord would be trespassing upon the renter's rights if entry is made without proper notice and authority (e.g., 24 hours' notice, daytime, knock first, except for emergency repairs, in case of fire, flood, etc.). What: Rented real estate may include all or part of almost any real property, such as an apartment, house, building, business office(s) or suite, land, farm, or merely an inside or outside space to park a vehicle, or store things. The premises rented may include not only specific rooms, but also access to other common areas such as off-street parking, basement or attic storage, laundry facility, pool, roof-deck, balconies, etc. The agreement may specify how and when these places may be used, and by whom. There may be detailed description of the current condition of the premises, for comparison with the condition at the time the premises are surrendered. When: the term of the rental may be for a night (e.g., a hotel room), weeks, months, or years. There may be statutory provisions requiring registration of any rental that could extend for more than a specified number of years (e.g., seven) in order to be enforceable against a new landlord. A typical rental is either annual or month-to-month, and the amount of rent may be different for long-term renters (because of lower turnover costs). Leaving a long-term lease before its expiration could result in penalties, or even the cost of the entire agreed period (if the landlord is unable to find a suitable replacement tenant, after diligent pursuit). If a tenant stays beyond the end of a lease for a term of years (one or more), then the parties may agree that the lease will be automatically renewed, or it may simply convert to a tenancy at will (month-to-month) at the pro-rated monthly cost of the previous annual lease. If a tenant at will is given notice to quit the premises, and refuses to do so, the landlord then begins eviction proceedings. In many places it is completely illegal to change locks on doors, or remove personal belongings, let alone forcibly eject a person, without a court order of eviction.
