If you are renting your home for less than 30 consecutive nights, you are required to have a license through the Minnesota Department of Health. This license needs to be renewed annually.
Any place offering lodging for a week or less should have hotel/motel license, this includes most vacation rentals. Long term (greater than 1 week) places such as boarding establishments, nursing homes, etc. need a lodging license with Minnesota Department of Health or with compliance and monitoring if they offer services (this does not apply to vacation rentals). Bed and breakfasts also need a lodging license and a food license.
Be sure that your rental is compliant with all safety standards listed. To learn more, please contact Minnesota Department of Health or go to their website to download appropriate forms. https://www.health.state.mn.us/communities/environment/recreation/lodging/index.html
