Passing Weymouth’s Smoke/CO Inspection Before Closing

Selling in Weymouth and worried the smoke and carbon monoxide check might delay your closing? You are not alone. Many sellers overlook a few small details that cause avoidable failures and last-minute stress. In this guide, you will learn exactly what the Weymouth Fire Department looks for, how to schedule on time, what it costs, and the easy fixes that help you pass the first time. Let’s dive in.

What this inspection is and why it matters

Local fire departments enforce Massachusetts law at the time of sale, which means your home must pass a smoke and CO alarm inspection before you can close. The rules come from state law for smoke detectors and carbon monoxide alarms, and local inspectors apply them at your property. You receive a Certificate of Compliance after you pass, and you will need it for closing.

• See the statutes for smoke detectors and carbon monoxide alarms for the legal basis: M.G.L. c.148 §26F and M.G.L. c.148 §26F1/2.

What inspectors check: smoke alarms

Inspection standards follow state rules and your home’s construction or renovation history. The state’s guide is a helpful reference for what to install and how to prepare. Massachusetts DFS preparation guide.

Placement basics

Inspectors expect smoke alarms on every habitable level, including basements and finished attics, at the base of stairways to upper floors, and outside each separate sleeping area. Newer-code homes may also require alarms inside bedrooms. Placement must follow code and manufacturer instructions. Municipal guidance illustrates these standards in practice. Example placement guidance.

Power, interconnect, and technology

Your permit date drives what type of alarm is required. Older homes that were never substantially renovated often can use battery units, while homes built or renovated after certain dates generally require hardwired, interconnected alarms with battery backup. Newer replacements typically must be photoelectric or photoelectric equipped. The state’s guide explains these differences by era. State preparation guide.

Age and replacement

Inspectors check manufacture dates. Replace any smoke alarm that is more than 10 years old or has no date on the unit. Battery-only replacements in many pre-1975 homes must be sealed 10-year units when required under the state guide. State preparation guide.

What inspectors check: carbon monoxide alarms

CO alarms are required in most homes that have fossil-fuel equipment or an attached garage. You must have working CO protection to pass the sale inspection. CO statute.

CO placement quick rules

Expect to place CO alarms on every level with habitable space and within 10 feet of each bedroom door. The exact setup must follow code and the device instructions.
