Overview of The Royal York I at 425 East 63rd Street

The Royal York I, built in 1956, is a full service condop located at 425 East 63rd Street in Lenox Hill. This well maintained building operates under condo rules, offering residents the flexibility of no board interviews and immediate subletting from day one of ownership. The building features a recently updated lobby, hallways, and elevators, along with comprehensive amenities including a 24 hour doorman and concierge service, live-in resident manager, state-of-the-art fitness center, bike room, storage facilities, and on-site garage.

The building's crown jewel is its half acre of beautifully landscaped private gardens, a rare amenity in Manhattan that provides residents with tranquil outdoor space. Units range from 550 square foot alcove studios to expansive penthouses, including a remarkable penthouse combination spanning 2,725 square feet inside with a 1,295 square foot wraparound terrace. Many apartments feature hardwood floors, through wall air conditioning, and washer/dryer capability, with south facing exposures being particularly common throughout the building.

The Royal York I is notably investor friendly, permitting unlimited subletting, pied-à-terre ownership, co-purchasing, gifting, and 80% financing. The building maintains a no flip tax policy and welcomes pets with board approval. Its prime Lenox Hill location provides easy access to the East River Promenade, multiple subway lines including the Q, F, 4/5/6, and N/R trains, plus nearby amenities like Trader Joe's, Whole Foods, and Central Park.
