A building used for business purposes is a capital asset and is depreciated over it's useful life. The costs of construction are not a deduction, they are the cost basis for depreciation. Depreciation begins when the asset is entered into service.
When Does Depreciation Begin and End?
You begin to depreciate your property when you place it in service for use in your trade or business or for the production of income. You stop depreciating property either when you have fully recovered your cost or other basis or when you retire it from service, whichever happens first.
You place property in service when it is ready and available for a specific use, whether in a business activity, an income-producing activity, a tax-exempt activity, or a personal activity. Even if you are not using the property, it is in service when it is ready and available for its specific use.

A capital asset is an asset that benefits your business for more than one year. Most businesses will need capital assets such as equipment, a car, computer and office furniture. Capital assets must be depreciated and cannot be treated as an expense in the year they are acquired or put into service.
