Summary

Worcester requires every residential building with three to five dwelling units to have an approved monitored battery-powered or primary smoke detector under Chapter 10, Section 2 of the Revised Ordinances. Detectors must sit outside each separate sleeping area, and interconnected primary-powered detectors are mandatory in every common hallway. The fire chief enforces the section, and a Chapter 10 violation carries a $200.00 fine.

(a) Every building or structure occupied in whole or in part for residential purposes and containing not less than three nor more than five dwelling units, (as that term is defined in 780 CMR 201.0), as amended), shall be equipped with an approved monitored battery powered smoke detector or an approved primary smoke detector, (as defined by the General Laws, chapter 148, § 26D, as amended). (b) The said approved monitored battery powered smoke detector or approved primary powered smoke detector shall be installed in each dwelling unit outside each separate sleeping area... provided further, that in all common hallways... a series of interconnected approved primary powered smoke detectors shall be installed. The fire chief shall enforce the provisions of this section.

Full Breakdown

0. Subsection (a) requires an approved monitored battery-powered smoke detector or an approved primary smoke detector, using the definitions in General Laws chapter 148, Section 26D. Subsection (b) requires that detector to be installed in each dwelling unit outside each separate sleeping area, though the fire chief may allow monitored battery-powered detectors as the installed type, and requires a series of interconnected approved primary-powered smoke detectors in all common hallways of the building. The text names the fire chief as the enforcer of the section.

00 penalty for any provision of Chapter 10, with the fire chief as the enforcing person, so a smoke-detector violation is charged at that rate. The requirement is narrower than it may first appear: it targets the three-to-five-unit tier specifically, a size Worcester singles out for this local hallway and sleeping-area placement rule on top of whatever the state's own smoke-detector law, chapter 148 Section 26D, already requires for other building types.

Violations & Fines

Any violation of Chapter 10, including the Section 2 smoke-detector requirement, is punishable by a $200.00 fine under Chapter 15's fine schedule, with the fire chief named as the enforcing person. Section 2 itself directs the fire chief to enforce its installation and placement requirements directly.
