A certified appraiser or licensed provisional appraiser shall not be considered an employee under the provisions of section 31-275 if substantially all of the remuneration for the services performed by such appraiser, whether paid in cash or otherwise, is directly related to sales or other output rather than to the number of hours worked, and such services are performed by the appraiser pursuant to a written contract that contains the following provisions: (1) The appraiser, for purposes of workers’ compensation, is engaged as an independent contractor associated with the person for whom services are performed; (2) the appraiser shall not receive any remuneration related to the number of hours worked, and shall not be treated as an employee with respect to such services for purposes of workers’ compensation; (3) the appraiser shall be permitted to work any hours the appraiser chooses; (4) the appraiser shall be permitted to work out of the appraiser’s own home or the office of the person for whom services are performed; (5) the appraiser shall be free to engage in outside employment; (6) the person for whom the services are performed may provide office facilities and supplies for the use of the appraiser, but the appraiser shall otherwise pay the appraiser’s own expenses, including, but not limited to, automobile, travel and entertainment expenses; and (7) the contract may be terminated by either party at any time upon notice given to the other.
