The upper floors hold a six-room flat with a dishwasher and laundry, and a five-room flat with formal living and dining rooms. A one-bedroom, one-bath apartment occupies the ground floor and was remodeled in 2025. Each unit has its own water heater; the flats also have individual forced-air furnaces, while the ground-floor apartment uses electric baseboard heat. Both flats feature hardwood floors, crown molding, fireplaces, built-in shelving, and back porches with access to the backyard.
