RUBS income can be used to finance small businesses by providing additional income to the landlord or property owner. This additional income can then be used to finance small business operations, such as purchasing equipment, hiring staff, or expanding the business. However, it is important to note that RUBS income is not always allowed in all municipalities, and there may be restrictions on how it is implemented. To determine if RUBS is permitted in your area, contact your state’s public utility commission or your local National Apartment Association affiliate.
