Maintenance elements of a real estate lease can vary significantly depending on whether it is residential or commercial in nature. In most residential property leases, the landlord is responsible for all repairs and maintenance. In commercial properties there are varying agreements made that could make some maintenance the responsibility of the tenant. As in any contract, the responsibilities of the parties should be carefully and completely spelled out to avoid misunderstanding.
In the case of a retail or office establishment, there could be a requirement for maintenance of the fixtures, such as display cabinets, that would fall upon the tenant, while the structure and major building maintenance would be done by the landlord.
