The property is a 4,610± SF flex building on 0.34± acres with office and warehouse components. The office layout includes 5–7 private offices, a reception area, and a kitchenette. The warehouse offers clear-span space that is 80' deep and 37' wide, served by an 8' x 8' overhead door.
The site includes on-site paved parking and is positioned along Riverside Street in Portland, ME. Traffic counts are listed at 10,930± vehicles per day (AADT MaineDOT 2022), providing practical visibility for business use.
This configuration supports a tenant or owner-operator needing both working and administrative space in one location. The office portion was likely a former residence prior to the warehouse addition, and it could be converted back to create a live/work setup if desired. The paved parking and straightforward office/warehouse split make the building well-suited for small business operations that benefit from on-site storage and efficient access to the overhead door.
