Welcome to your opportunity to own TWO UNITS on one lot! 231 40th St features a charming 2-bedroom, 1-bath 868 sq ft main home PLUS a fully PERMITTED, DETACHED 1-bedroom 399 sf ADU apartment with its own address!(Unit 201), featuring a full kitchen, private deck, dedicated washer/dryer, separate utilities, and newer mini split HVAC. The apartment, which has enjoyed strong rental demand, offers ideal flexibility for rental income, guests, or multigenerational living. This sun-drenched East Sac property has been meticulously maintained and thoughtfully improved over the years. It is set on an oversized 6,438 sq ft lot, larger than many East Sac parcels. Inside the main home, timeless character and original hardwood floors blend beautifully with thoughtful upgrades including upgraded HVAC and insulation, updated electrical panel, newer water heater, and carefully maintained systems throughout. Outside, the fully redesigned yard feels like a private garden retreat with a soothing water fountain, stamped concrete, 'smart' drip irrigation, drought-resistant landscaping, native pollinator-friendly plants, lavender, flowering vines, fruit-bearing Meyer lemon, fig, and apricot trees, plus a stunning mature Japanese maple, a large shed for extra storage and a 2-car garage, a rare find in East Sac. Every inch of the property reflects intentional care. The detached apartment sits at the opposite end of the yard and tucked among gorgeous trees, offering a unique level of privacy for guests or renters. Located just blocks from Compton's Market, Orphan Breakfast House, local restaurants, wine bars, parks, and beloved McKinley Park, this is a rare opportunity to own a beautifully cared-for East Sacramento property with both charm and income potential.
