File organization, energy efficiency, and other clerical tasks are the responsibilities when maintaining a home office or an ordinary office for that matter. General hygiene and structural maintenance are equally important if you want to have a space conducive for work. The quest for work efficiency and productivity does not end with paper work. It also includes a spotless workspace.

Just imagine, how would you like it when, one day, you were typing in front of your computer when water suddenly came seeping from the comfort room because there was an unattended leak? Or how do you like it when no client dares to enter your office because of the foul trash piling on a small hill just outside? Sure, it's somewhat an exaggeration, but it is not an impossible thing to happen.
Thus you will also have to put extra capital on these services like repairmen. exterminators. janitors, and the like. This is assuming that you are running a large office. If not, then maybe you ought not to hire janitors. There are also other items that you have to take into account items like garbage cans, detergents, air fresheners, and even faucets, pails, and buckets.
Your office may be called your second home because of the fact that you spend most of your day here. This is where you get your income. Like your home, you are obliged to make it as pleasant to stay in as possible. It is a reflection of who you are and what you are. You wouldn't want to be called a slob, would you?
