You work hard to line up a buyer, lock in dates, and keep your move on track. But without a passing Smoke and CO Certificate from the Wellesley Fire Department, your sale can stall at the finish line. If you’re selling in Wellesley, you’re responsible for meeting Massachusetts smoke and carbon monoxide requirements before closing. This guide gives you a step‑by‑step checklist, key local dates and fees, and practical tips to pass the first time. Let’s dive in.
What Wellesley requires at sale
Massachusetts law requires sellers to equip one‑ and two‑family homes with approved smoke alarms before transfer, and the local fire department enforces this at the time of sale. See the state statute for smoke alarms in M.G.L. c.148 §26F and carbon monoxide in M.G.L. c.148 §26F1/2.
In Wellesley, you schedule your Smoke/CO (26F) inspection online and pay a fee. The town lists single‑family inspections at $50, two‑family at $100, three–five family at $150, and six or more units at $500. Certificates are generally valid for 60 days, and the Fire Department asks you to book at least 10 business days before closing. Review the town’s process and hours on Wellesley’s Home Sale Inspections page.
The rules inspectors use
Inspectors apply the State Fire Code, which covers device type, placement, power source, and interconnection. This includes photoelectric technology in many scenarios, hush features on new replacements, and allowances for sealed long‑life battery smoke alarms in some older homes. CO alarms must be on every level, including habitable basements or attics, and within about 10 feet of sleeping areas. You can read the code framework at 527 CMR on law.cornell.edu.
Device lifespan matters. Smoke alarms are generally replaced at 10 years, and battery units without a printed manufacture date usually fail inspection. CO alarm life varies by model but is commonly 5–7 years. See state preparation guidance on Mass.gov.
A closing‑ready checklist
ASAP after you sign the P&S
- Confirm the home’s build date and any major renovation permit dates. Rules depend on these dates. State guidance stresses knowing this before you buy new devices. Check the prep guide on Mass.gov.
- Start an alarm inventory. List every smoke and CO unit, location, whether it is hard‑wired or battery, if it’s interconnected, and the manufacture date printed on the device.
Within days or the first week
- Replace expired or non‑compliant alarms:
- Replace smoke alarms older than 10 years or with no date. New battery units should use sealed 10‑year batteries and include a hush feature; photoelectric technology is recommended by state guidance. See Mass.gov prep guidance.
- Replace CO alarms at the manufacturer’s end‑of‑life and confirm you have CO coverage on every level and near sleeping areas as required by the State Fire Code. Review placement basics in 527 CMR.
- If your build or renovation history requires hard‑wired, interconnected alarms, hire an electrician to install compliant units. If you use an alarm system, confirm compatibility and interconnection. Local department guidance on interconnection shows what inspectors expect; see an example overview from Westford Fire.
- For monitored systems, arrange test mode and ensure someone can operate the keypad during the inspection. Wellesley expects systems to be in test mode; see Wellesley’s inspection notes.
Schedule your Wellesley inspection
- Book online at least 10 business days before closing through the town portal, and consider scheduling 2–4 weeks ahead because slots can fill. Remember the certificate is valid for 60 days, so time it with your closing. Details are on Wellesley’s Home Sale Inspections page.
On inspection day
- Make sure your street number is visible. Have access to attics, basements, and utility spaces.
- Put any monitored system in test mode and have someone present who can operate it. Inspectors may remove a device briefly to verify the manufacture date.
- If you pass, the Fire Department issues the 26F Certificate of Compliance. If you do not pass, fix the issues and schedule a reinspection. See Wellesley’s process.
Before closing
- Provide the certificate to your attorney and lender. Most closings require it at the table. For a full prep overview, see Mass.gov’s inspection prep guide.
Common pitfalls and how to avoid them
- Expired or undated devices. Inspectors often fail units without a date or past end‑of‑life. Replace early. Reference: Mass.gov prep guidance.
- Wrong placement or device type. Missing alarms outside sleeping areas, missing a level, or using the wrong technology can trigger a fail. See placement/type reminders in local guidance, such as Hanson Fire’s checklist.
- Missing required hard‑wiring or interconnection. If permits or build dates require this, plan for an electrician and extra time. See examples in Hanson Fire’s guidance.
- Monitored systems not in test mode or no one present to operate the keypad. Wellesley may not complete the inspection without this step; see Wellesley’s notes.
Timeline and cost basics in Wellesley
- Fees: single‑family $50; two‑family $100; three–five family $150; six or more units $500. Payment can be made online or by check at the inspection. See Wellesley’s fee table.
- Certificate validity: generally 60 days. If your closing slips, you may need a new inspection.
- Time buffer: simple battery replacements are quick and low cost; adding or updating hard‑wired, interconnected alarms takes longer and may require an electrician. Leave 1–2 weeks of contingency.
Quick pre‑inspection mini‑checklist
- Confirm build and renovation permit dates.
- Inventory all smoke and CO alarms with manufacture dates and locations.
- Replace smoke alarms older than 10 years or without dates; use sealed 10‑year battery photoelectric units with hush features when replacing battery models.
- Confirm CO alarms on every level and within about 10 feet of bedrooms.
- Ensure your house number is visible from the street.
- Put monitored alarms in test mode and have someone present to operate the system.
