Massachusetts Approved Exit Signs – Code-Compliant Emergency Egress Solutions

If you’re installing or replacing exit signage in Massachusetts, your fixtures must meet strict state and national code requirements. Massachusetts approved exit signs must comply with the Massachusetts State Building Code 780 CMR, applicable sections of the International Building Code (IBC), and product listing standards such as UL 924.

Whether you’re working on a commercial building, multi-family property, school, warehouse, or retail space, using properly listed and installed exit signs ensures safety, inspection approval, and liability protection.

What Makes an Exit Sign “Massachusetts Approved”?

To be considered code-compliant in Massachusetts, exit signs must meet the following requirements:

✔ UL 924 Listed

All internally illuminated exit signs must be UL 924 listed for emergency lighting and power equipment. This ensures the unit:

• Automatically switches to battery backup during power failure

• Provides a minimum of 90 minutes of emergency illumination

• Meets national life safety testing standards

✔ Proper Letter Size & Visibility

Under 780 CMR and IBC requirements:

• Letters must be at least 6 inches high

• Stroke width must be minimum ¾ inch

• The word “EXIT” must contrast clearly with the background

• Signs must be visible from any direction of egress travel

✔ Continuous Illumination

Exit signs must be illuminated at all times when the building is occupied, including during emergency conditions.

✔ Placement Requirements

• No point in an exit access corridor may be more than 100 feet from a visible exit sign

• Directional arrows must be used when the path of egress is not obvious

Massachusetts-Specific Considerations

Massachusetts enforces additional safety standards beyond baseline IBC adoption.

Multi-Family Dwellings

Under Massachusetts General Laws, certain residential occupancies (10+ units) require illuminated exit signage with emergency backup power.

Accessibility Compliance

Accessible means of egress may require additional signage elements under state accessibility rules, including identification of accessible exits when applicable.

Always confirm requirements with the local Authority Having Jurisdiction (AHJ), as some municipalities enforce stricter interpretations.

Types of Massachusetts Code-Compliant Exit Signs

For commercial and industrial properties, approved models typically include:

• 🔴 LED Exit Signs with Battery Backup

• 🟢 Red or Green Letter Exit Signs

• ↔ Universal Mount (Ceiling/Wall/End Mount) Exit Signs

• 🔁 Combo Exit & Emergency Light Units
  

All units should clearly list:

• UL 924 certification

• Input voltage (120/277V standard)

• Emergency runtime rating

• Damp or wet location rating if required

Why Code Compliance Matters

Using non-listed or improperly installed exit signs can result in:

• Failed building inspections

• Fire marshal violations

• Insurance issues

• Increased liability exposure

Massachusetts building inspectors review exit signage during construction, renovation, and annual life safety inspections.

Choosing the Right Exit Sign for Your Project

When selecting a Massachusetts approved exit sign, verify:

• ✅ UL 924 listing

• ✅ 90-minute battery backup

• ✅ Proper letter size & visibility

• ✅ Mounting type for your application

• ✅ Compliance with 780 CMR and IBC

If you are unsure about application requirements (commercial, industrial, healthcare, multi-family), consult your electrician or local building department before installation.
