Yes and no. An employee or independent contractor who receives housing is considered a tenant for most purposes during the tenancy. The property owner, for example, has an obligation to provide the resident with a habitable dwelling. I could not tell you whether specific laws like Megan's law apply to employees, but prudence would suggest that for those purposes you treat the employee as a tenant.
The rule is different when the employment ends. When an employee receives housing as part of employment, the employee's right to the housing ends when the employment ends. You would not have to give the employee 30-days or any other notice, although if the employee did not leave right away you would still have to bring an unlawful-detainer action.
Whether the same rule applies to an independent contractor is not clear. Most likely, anyone working for you who had to live on the property would not be an independent contractor, anyway.
In addition to the accurate information already provided by my colleague, I wanted to warn you that the IWC Wage Order for your industry has a table of the value for room and board you are allowed as credit toward the minimum wage, and the requirements for allowing such credits (like a written agreement).
Good luck to you.
