About this home

Here's your rare and exciting opportunity to own a remarkable piece of Portland history or to reimagine or create your version of this incredible urban oasis. In the heart of the Old Port tucked away on an astonishingly quiet dead end street, the legal use for this lovingly renovated, charming example of 1800s design is a 2-family, but has been most recently utilized and recognized as a large single family home with a 1st floor in-law apartment with separate entrance. Bathed in natural light, and renovated by the owners since 1992. 3 bedrooms and 3.5 baths with flexible usage and floor plans, this truly special home was the house that art, love and hard work built. Both owners were and are local artists of note, C. Michael Lewis and Mary L. Hart. Michael's architectural knowledge is on full display through the home and Mary's love and dedication to the beauty of nature is reflected in the incredible garden that they mitigated and created whole-cloth. They reveled in this enchanting little garden haven and even kept chickens until 2024. Off-street tandem parking with the driveway, plans for a garage were drafted but not submitted. Abutting Pleasant Street Park and walkable to anything and everything that the Old Port affords, the location, amenities and possibilities are abundant and apparent, you have to see it for yourself! * Please submit offers by 12:00 noon Tuesday 8/19 with a response time of 12:00 noon the following day, Wednesday 8/20. *

Downtown Business District

To maintain and enhance the role of the downtown as the business and commercial center of the region, and to enhance and promote the orderly expansion of retail and service businesses downtown, satisfying the related needs of the city’s resident, working, and visitor populations. The B-3 zone encourages increased housing opportunities downtown, including three-family, four-family, townhouse, and multi-family structures to accommodate Portland’s diverse residential population, and supports an active, walkable pedestrian environment through the encouragement of intensive mixed-use activities, enhancement and maintenance of public and private open space, and the enlivenment and increased attractiveness of the street environment. Standards of the B-3 zone require excellence in urban design, to preserve and capitalize on the unique character and historic fabric of downtown Portland by encouraging reuse of significant existing structures and providing opportunities for an enhanced presence and integration of arts and cultural activities. The zone reinforces the role of downtown as a meeting place for community residents and visitors alike from all walks of life and all socio- economic groups by prioritizing access via multiple modes of transportation and enhancing and protecting the pedestrian environment.
