Once you have obtained all these documents, you can now hire a home improvement contractor to get your projects completed. You can obtain the license and permit from the state Department of Health. However, most homeowners do not bother to get a copy of their health inspection certificate and then trust fund (in case their business fails). When you fail to report problems related to the home improvement, the Board of License will suspend your business until the next inspection; however, if you successfully complete the project, your home improvement company should send you a payment for the services provided, which is considered income to the business.
