Facility Overview
The 425 Massachusetts Ave Parking Garage, professionally operated by LAZ Parking, is a modern and secure underground parking facility located in the vibrant Mount Vernon Triangle neighborhood of Washington, D.C. Serving both the prominent 425 Mass residential community and commercial visitors to the Downtown East district, this subterranean garage features clean, well-marked spaces, bright LED illumination, and an automated access control setup. The facility is well-suited for everyday passenger cars, crossovers, sedans, and compact-to-midsize SUVs. However, as with most underground garages in central D.C., drivers should note the standard vertical clearance limit of approximately 6 feet 8 inches (2.03 m). High-roof commercial vans, lifted trucks, or vehicles equipped with rooftop cargo boxes and bike racks should verify clearance prior to driving down the ramp.
Prime Location & Nearby Attractions
Positioned on the north side of Massachusetts Avenue NW between 4th and 5th Streets, this facility boasts an exceptionally strategic location that bridges the bustling Mount Vernon Triangle, Chinatown, and Judiciary Square. Guests are situated just a short 7 to 10-minute walk (under 0.4 miles) from Capital One Arena, making it a favorite staging ground for Washington Wizards and Capitals games, premier concerts, and family arena shows. The Walter E. Washington Convention Center is located merely four blocks northwest, easily accessible in under 8 minutes for trade shows, expos, and global summits. Other nearby landmarks within easy walking distance include the historic National Building Museum (5 minutes south), the Chinatown Friendship Archway, the Smithsonian American Art Museum, and the National Portrait Gallery. The neighborhood also offers a thriving culinary scene, with acclaimed restaurants, casual cafes, and groceries like Safeway right along 4th and 5th Streets.
Access, Navigation & Transit Connectivity
Ingress and egress are straightforward via Massachusetts Avenue NW and the adjacent alley network connecting H Street NW and I Street NW. The facility provides efficient post-event egress compared to garages directly adjacent to Capital One Arena, allowing drivers to quickly access the I-395 3rd Street Tunnel without navigating heavy arena pedestrian foot traffic. For intermodal commuters, the garage is surrounded by top-tier public transit options. Gallery Place-Chinatown Station (Red, Green, and Yellow Metrorail lines), Mount Vernon Square 7th St-Convention Center Station (Green and Yellow lines), and Judiciary Square Station (Red line) are all located within 5 to 8 minutes on foot. Multiple Metrobus routes run directly along Massachusetts Avenue and H Street, and D.C. Union Station is only a five-minute drive or fifteen-minute stroll to the east.

Visitor & Driver Tips
Because of high demand during major sporting events, sold-out concerts, and national conventions, street traffic on Massachusetts Avenue can build up rapidly. Reserving your parking spot in advance using digital parking apps is strongly recommended to lock in prevailing rates and guarantee a space. If attending an event at Capital One Arena, plan to arrive 45 to 60 minutes before tip-off or puck-drop to enjoy a leisurely walk through Chinatown and beat local pedestrian crowds. When returning to your vehicle, have your digital barcode or validated parking ticket ready at the reader to ensure a smooth exit.
