Situated on a peaceful 1.29-acre lot in South Lebanon Township, this unique Low Density Residential–zoned property offers exceptional flexibility for owner-occupants, residential living, or income-producing use. Built in 1977, the property features a contemporary ranch-style main residence with a substantial addition, an attached in-law suite with a private entrance, and a detached two-car garage with a spacious two-bedroom apartment above—creating up to three separate living spaces on one parcel. The main home offers 2 bedrooms and 2 full bathrooms (originally a 3-bedroom layout), along with traditional living and dining rooms adjacent to the kitchen. A standout feature is the large 28’ x 34’ addition with vaulted ceilings, providing an impressive family room or entertainment space. The main house includes central air conditioning, a rear deck, and access to the basement, which houses the mechanicals and offers abundant storage. The attached in-law suite, currently rented as a separate apartment, includes 1 bedroom and 1 full bathroom, its own living space, central air conditioning, and an electric heat pump. The owner currently pays electric for this unit. This space is ideal for extended family, guests, or continued rental income. The detached garage is exceptionally versatile, featuring a large two-car garage bay, its own restroom, and extensive storage. Above the garage is a well-sized 2-bedroom, 1-bath apartment, currently rented, with tenant-paid electric, oil boiler heat serving the garage and apartment, and no cooling. This apartment provides excellent separation and privacy. The property is served by well and septic for all structures, with public sewer available at the street. Outdoors, the property truly shines with a large, beautiful yard, an operational in-ground pool, and ample space for recreation and relaxation. In addition to the two-car garage, the property offers plenty of off-street parking with two separate driveways, easily accommodating multiple households or guests. Whether you’re an owner-occupant looking to offset your mortgage with rental income, planning for multi-generational living, or an investor seeking a rare multi-unit opportunity in a residential setting, 645 S 14th Avenue delivers space, privacy, and versatility in a quiet yet convenient Lebanon County location.
