Hi and welcome to Just Answer!
Housing assistance provided by an employer is considered as fridge benefit and included into wages of an employee. There are some exemptions however...
The value of lodging is not included into income if the lodging is furnished for the employer’s convenience, on the employer’s premises, and as a condition of employment.
For reference - see page 16 in this publication - http://www.irs.gov/pub/irs-pdf/p15b.pdf
Any fringe benefit provided by the employer is generally taxable and must be included in the recipient’s pay unless the law specifically excludes it.
Please let me know if you need any help or clarification.
