Owners of residential properties with ten or more units are expected, under 105 Mass. Code Regs. § 410.310, to install auxiliary emergency lighting and properly marked exit signs that comply with M.G.L. c. 143, § 21D. Compliant operators typically conduct routine inspections and maintenance of these systems to confirm they remain fully functional. Keeping maintenance logs and promptly addressing any failures or deficiencies are practices commonly associated with meeting this ongoing obligation.

105 Mass. Code Regs. § 410.310 establishes that tenants living in buildings of ten or more units have a right to functional auxiliary emergency lighting and exit signs maintained by their building owner. If these systems appear broken, missing, or inadequately maintained, tenants may report the condition to the local board of health or housing inspection authority, which has authority to investigate and enforce minimum standards. Tenant-rights organizations in Massachusetts can also provide general information about available options when a landlord appears to be out of compliance with this provision.
