511 Congress St
Portland, ME 04101
Ocean Gate Plaza · Office Property For Sale

Porta & Company is pleased to present the opportunity to acquire 511
Congress Street ("511 Congress" or "the Property"), a 128,400 square
foot Class A office building with a 256 space on-site parking garage in
the rear right in the heart of Downtown Portland. The property at 511
Congress enjoys a premier location opposite Monument Square in the
center of the city. With the ability to immediately occupy full floors and
the ability to take advantage of the opportunity zone program, this
opportunity is ideal for both investors and owner occupants.
511 Congress is occupied by a diverse tenant roster compromised of
a mix of office tenants and first floor retail users including an 8,500 sf
gym. With the office market returning post pandemic, the building
provides inherent value realized through near term rollover and the
lease up of the existing vacancy.
Originally built in 1973, and renovated 2013-19, 511 Congress Street
is one of the most identifiable buildings in Portland. The Property was
renovated with a vision of providing open floor plates to allow for
flexible layout concepts. The building features a state of the art secure
Class-A entryway and lobby combined with an on-site concierge and
secure elevators. Situated on Congress St, the center core design of
the building provides tenants with 360° views of Portland and the
surrounding towns.
Few urban assets compare to the transit oriented opportunities that
511 Congress offers. The 256 space parking garage with access from
both Brown and Casco Street allows for convenient access to I-295.
With a public transportation stop directly across the street from the
entrance, the building stands in the center of a highly trafficked
pedestrian area in one of the most prominent areas of Portland. This
central location and on-site garage offer premier visibility and access
for existing and attracting future retail and office tenants.
