# Building

In order for a building to produce $LAY, it must first sign a contract with Distrtict. To contract with District, let's list the Building.

Building owners can set various contract terms that they want. Building owners can set the tax to be paid to the District owner at a rate between 10% and 20%, and Building owners can set the minimum level or tier of District you want to enshrine. Building owners can also contract with a specific number of Districts if they wish.&#x20;

Once Building owners have a contract with a District, Building owners can start producing $LAY by Building. In order to produce $LAY with high efficiency, Building owners need to repair the Building. The $LAY is spent on repairs.<br>

Building owners can terminate their contract with the District at any time, starting one week after signing the contract, by 'Demolish'. If they do not terminate the contract, it will be automatically extended.<br>
