A Farm Built Over Time. Ready for It's Next Chapter. There is something different about a farm that has been built over generations. Rather than created all at once, Mt. Calvert Farm has evolved with purpose—quality buildings added, pastures divided, utilities expanded and infrastructure developed as the needs of the farm grew. Today, over 15 acres offer the foundation for the next owner to continue that legacy, whether envisioned as a private equestrian property, livestock operation, hobby farm or multi-purpose agricultural retreat. At the heart of the property is the 1950s brick Cape Cod farmhouse, updated over time and offering more than 3,600 square feet, four bedrooms, two of which are main level and two full baths. Extensively refreshed for 2026, the home features a new air-conditioning system, new water system, new LVP flooring on the main level, new upper-level carpeting, fresh interior paint and new lighting and ceiling fans throughout. One full bath has been completely renovated with a walk-in shower, while the second received updated flooring, vanity, lighting, toilet and fan. A fireplace, unfinished basement with approximately 10-foot ceilings and a detached three-car garage with a two way paved driveway completes the residential portion of the property. Beyond the farmhouse, the scale of the farm begins to unfold. Fourteen fenced pastures/paddocks, multiple field water points, run ins, two wells and two septic systems support an unusually substantial collection of agricultural improvements. The Big Upper Barn is the centerpiece of the equestrian facilities: an approximately 84' x 40', 12-stall center-aisle barn with 12' x 12' stalls, rubber mats, individual stall fans and hot/cold water service, a wash area, office/tack room and full-length upper hay loft with a working hay elevator. Nearby, the Small Barn provides additional flexible stalls of varying sizes, lending itself to ponies, livestock, foaling or supplemental farm use. Constructed in approximately 2007, the Lower Livestock Barn expands the property's capabilities beyond horses, with oversized stalls and livestock areas, rubber matting, multiple utility sinks, a break room and full bathroom—valuable infrastructure for a working animal operation. A substantial indoor Morton riding arena, originally constructed circa 1990, provides year-round training and riding space with multiple overhead bay light fixtures, large sliding access doors and 4ft kick walls. Adjacent to this portion of the property is the Farm Operations Center, constructed circa 2013 and offering approximately 1,226 square feet, with two offices, two full baths, kitchen, laundry and living/meeting space—an exceptionally useful headquarters for managing the property, meeting with veterinarians or farm professionals, maintaining records or supporting day-to-day operations. Additional farm infrastructure includes run-in sheds, a very large mechanics/equipment shed, largehicken coop, field water stations, extensive fencing and heavy-duty tube gates. A second driveway and recorded access easement lead to the arena and Farm Operations Center, terminating in a circular gravel drive that facilitates access. What makes Mt. Calvert Farm compelling, however, isn't any single building. It is everything already here and only 35 minutes from Annapolis and 45 Minutes from Washington DC Locally you are 20 minutes from the Prince George's Equestrian Center and 10 minutes from Patuxent River Park and even down the road from putting your kayak in at Mount Calvert Historical and Archaeological Park. Set within the historic agricultural landscape of Mount Calvert and the Patuxent River countryside, Mt. Calvert Farm is ready for another steward, another vision and another chapter. The land is here. The infrastructure is here. The legacy has already begun. What comes next is yours.
