About This Home

15 Union Street

Updated two-unit property located close to downtown Peterborough. Unit A, on the first floor, offers 2 bedrooms plus a bonus room that could serve as an office, dining room, or additional living space. Unit B offers 2 bedrooms and 1 bath. Both units feature renovated kitchens and bathrooms, updated flooring and paint, and washer/dryer hookups. Significant improvements completed in 2025–2026 include a new roof, 22 replacement windows, plumbing updates, exterior painting, and a fully updated 400-amp electrical service with separate panels for Unit A, Unit B, and house/common areas so plenty of availability to add Mini-splits if desired. Primary heat is electric with a shared oil furnace retained for backup. Off-street parking. The property retains the character and some of the quirks of an 1800s home while benefiting from substantial recent updates. Seller is a licensed real estate agent.
