(a) An applicant for or recipient of public assistance is exempt from complying with any requirement concerning eligibility for public assistance if the applicant or recipient establishes that good cause exists for failing to comply with the requirement. Except where otherwise specifically set forth in any provision of this Title, good cause for failure to comply with an eligibility requirement exists when:

1. (1) the applicant or recipient has a physical or mental condition which prevents compliance;
2. (2) the applicant's or recipient's failure to comply is directly attributable to social services district error; or
3. (3) other extenuating circumstances, beyond the control of the applicant or recipient, exists which prevent the applicant or recipient from being reasonably expected to comply with an eligibility requirement.
