According to Massachusetts General Laws (MGL) Chapter 151B, Section 5, any person claiming to be aggrieved by an alleged unlawful practice, including housing discrimination, must file a complaint with the Massachusetts Commission Against Discrimination (MCAD). The statute explicitly states that such a complaint must be filed within 300 days after the alleged act of discrimination occurred. Failure to file within this statutory period will result in the dismissal of the complaint for being untimely.

A. 150: This is an incorrect time frame and does not align with the statutory requirement under MGL c. 151B, § 5.

B. 200: This is an incorrect time frame and does not align with the statutory requirement under MGL c. 151B, § 5.

D. 365: This is incorrect. While the federal Fair Housing Act allows up to one year (365 days) to file a complaint with HUD, the specific Massachusetts state limit for filing with MCAD is 300 days.

1. Massachusetts General Laws, Chapter 151B, Section 5. The official text of the law states: "Any complaint filed pursuant to this section must be so filed within 300 days after the alleged act of discrimination." (Source: The General Court of the Commonwealth of Massachusetts, Official Website).

2. Massachusetts Commission Against Discrimination (MCAD) Official Documentation. The "Filing a Complaint" section on the official MCAD website confirms the deadline: "A complaint must be filed with the MCAD within 300 days of the date of the alleged discriminatory act."

3. Suffolk University Law School, Housing Discrimination Law Course Materials. Syllabi and course materials covering Massachusetts fair housing law consistently cite the 300-day statute of limitations for filing complaints with the MCAD as established by MGL c. 151B, § 5.
