The category on the Rental Rates page, determines your security deposit and first months rent.
If you use more hours during the month than your category allows, you pay the amount per hour over your minimum usage. The amount of hours are recorded by each tenant on a monthly form, that is furnished for you at the kitchen. You will be billed at the end of the month, and the money for additional hours is due by the first of the next month. In another words, Please pay the additional hours by the next time rent is due.
The rules are reasonable and will not be bent for any reason!!
