Well, the same general principles will be applied, but there are some differences. Basically, if your personal income can support both your expenses and the business expenses with a lower than 50% debt-to-income ratio, you'll be sitting pretty.

However, if you are unable to, some companies will give loans out based on the owners credit, as well as the business plan. Make sure that when you apply for your commercial loan, you have a well thought out, accurate business plan drawn up. If the bank believes that it will be profitable, they are far more likely to lend money out. If it is a well established business, you'll need accurate "books" for the business, likely for the last 2 or more years.

Depending on how much the business is going to cost, as well as the amount of equity you have in your home, you may want to take out a second mortgage to finance the business. Although you would want to speak with a tax professional to be sure, from my understanding it may be more advantageous tax-wise.
