4 Portland Street is the tax record for a single family house located on Portland Street, Bridgton which Mrs. Harriet B. Jones owned at the date of this survey, around 1938.

Assessors later updated the card to reflect ownership by Walter Jones (non-resident) and later Elena B. and Edward C. Hall Jr.

The address given is the address at the time of the survey, and has probably changed since then. The card references a deed dated 1903; this is not the date of the photograph.
