106 CMR, § 362.120
Residency shall be verified before initial certification except in unusual cases (such as homeless households, certain migrant farmworker households, or households that have just arrived in the state) where verification of residency cannot reasonably be accomplished. As much as possible, documents used to verify rent or mortgage payments, utilities, or identity shall be used to verify residency. If such documentation does not verify residency, the Department shall use any documents, collateral contact, or home visits that reasonably establish the applicant's residency in accordance with 106 CMR 361.640: Sources of Verification. No requirement for a specific type of verification may be imposed. The Department shall not limit verifications to a single document and must assist the household in obtaining verification, when necessary, pursuant to 106 CMR 361.650: Responsibility for Obtaining Verification.
