No. The disaster loan is intended to help you return your property to its pre-disaster condition and, under certain circumstances, for mitigating devices. Normally, SBA funds cannot be used to expand or upgrade a business. If, however, city or county building codes require such upgrading, then you can use the SBA loan for that purpose. Your loan will be made for specific and designated purposes. Remember that the penalty for misusing disaster funds is immediate repayment of one-and-a-half times the original amount of the loan. The SBA requires that you obtain receipts and maintain good records of all loan expenditures as you restore your damaged property, and that you keep these receipts and records for three years.
