The issue really is only whether you have a written employment contract which guaranteed you the housing as part of compensation. If you do, it is enforceable in court: your husband could sue for breach of contract to force them to provide alternate equivalent housing or pay the reasonable fair market value of the housing you had been getting. Unfortunately, if you did not have a written employment contract, your husband's employment was "employment at will." This means, among other things, that the employer may change the terms of employment, including compensation--e.g. the provision of housing--at will, for any reason, without prior notice. Unfortunately, in the absence of a still-in-effect (unexpired) written contract for a definite or defined term (e.g. a one-year contract) all employment is employment at will and is under the employer's sole control. So without a contract, they could do this. The hardship on you and your family is, unfortunately, not a consideration.
