From IRS site:
If you receive rental income from the rental of a dwelling unit, there are certain rental expenses you may deduct on your tax return. These expenses may include mortgage interest, property tax, operating expenses, depreciation, and repairs.
You can deduct the ordinary and necessary expenses for managing, conserving and maintaining your rental property. Ordinary expenses are those that are common and generally accepted in the business. Necessary expenses are those that are deemed appropriate, such as interest, taxes, advertising, maintenance, utilities and insurance.
You can deduct the costs of certain materials, supplies, repairs, and maintenance that you make to your rental property to keep your property in good operating condition.
You can deduct the expenses paid by the tenant if they are deductible rental expenses. When you include the fair market value of the property or services in your rental income, you can deduct that same amount as a rental expense.
