Security Deposit Return Deadline in Massachusetts

In Massachusetts, a landlord must return your security deposit within 30 days after move-out. Missing this deadline often forfeits the landlord's right to keep any portion of the deposit, and many Massachusetts tenants recover additional statutory damages for bad-faith withholding.

Massachusetts HOA Law

HOA fines and assessments in Massachusetts are governed by the Massachusetts Condominium Act (MGL Chapter 183A). This law generally requires written notice, an opportunity to be heard, and documented evidence before a fine becomes enforceable.

Massachusetts Utility Regulator

Utility billing disputes in Massachusetts fall under the Department of Public Utilities (DPU) — mass.gov/dpu. Your utility generally cannot disconnect service while a formal billing complaint is pending with the regulator.
