Rules by state
Pennsylvania
Pennsylvania’s statewide sale/transfer rule is narrow: I found a state-law requirement to disclose carbon monoxide detector installation when selling a residential building, through the seller disclosure process. I did not find a statewide Pennsylvania requirement for a separate smoke-alarm/CO-alarm transfer certificate for an ordinary home sale; smoke alarm compliance is mainly governed by the Uniform Construction Code for construction or alteration work.
Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.
- At sale or transfer
- For a typical Pennsylvania residential sale, the statewide rule I found is seller disclosure of carbon monoxide detector installation on the official property disclosure statement; I did not find a separate statewide smoke/CO transfer certificate requirement or statewide fire-extinguisher transfer requirement for ordinary homes.
- Code reference
- Act 121 of 2013, §4(a) (Carbon Monoxide Alarm Standards Act); 68 Pa.C.S. Ch. 73; 34 Pa. Code §403.21

Key facts for Pennsylvania
- Carbon Monoxide Alarm Standards Act §4(a): on sale of a residential building, the seller must disclose carbon monoxide detector installation on the Chapter 73 property disclosure statement.
- I found no statewide Pennsylvania law requiring a separate smoke-alarm or carbon-monoxide transfer certificate for an ordinary home sale.
- 34 Pa. Code §403.21 adopts IRC 2021; for one- and two-family alterations, repairs, or additions, interconnected smoke alarms are not required, but battery-operated alarms are.
- For code-triggered alarm work, inspections are by municipal building code officials or Department-certified third-party UCC agencies, not a special statewide sale inspector.
- Ready PA says smoke alarms belong inside every bedroom, outside each sleeping area, and on every level of the home.
- I found no statewide ordinary-home sale rule requiring a fire extinguisher at transfer; Ready PA treats extinguishers as home-safety equipment, not a transfer certificate item.
What to do next
- Before signing the transfer agreement, complete the official Seller's Property Disclosure Statement and answer the carbon monoxide detector section accurately.
- If you installed or changed alarms during remodeling or repair, ask your municipality or a certified third-party UCC agency whether permit and inspection requirements applied.
- Replace old smoke alarms, test every alarm before closing, and confirm bedroom/level placement against Ready PA guidance.
