History

This house is a fine example of the two story Georgian dwellings built in Newburyport during the early-to-mid eighteenth century. The house is, in fact, two attached dwellings. If detached, each would have a symmetrical five bay facade. The building is two stories in height and has a hipped roof. Each of the dwellings has a central chimney. The doorways had been altered, but are now closer to their original character.

The earliest owner of this house has yet to be documented. It is quite possible that this house was owned by Offin Boardman. Boardman laid out a way through his land in 1754. It was thereafter called Boardman’s Lane. Offin Boardman was the owner of several Merrimack-built vessels.

In 1851 this property was owned by Mrs. Judith Boardman. Also in residence at the time was Greenleaf Boardman who ran a livery stable on Merrimac Street. Prior to 1872 the property was conveyed to Mrs. Hannah T Marshall. Also in residence at that time was Henry O. Marshall, mariner, and Offin B. Marshall, carpenter. Later Offin B. Marshall willed the house to Alice V. Goodwin who owned it until 1927.

Reviews that may apply

Newburyport Historic District (National Register, listed 1984), contributing in the 1984 nomination · Demolition Control Overlay District (DCOD) · Parcel 50-41 · Zone R2

  1. Zoning Board of Appeals decides

    Listed as contributing in 1984, so removing more than 25% of its exterior walls, counted cumulatively since 2014 and including walls enclosed by an addition or openings filled in, needs a DCOD special permit; the Board may grant one only if the building retains no substantial remaining market value or reasonable use. The Historical Commission sends an advisory report. Replacing siding, or windows and doors in their openings, does not count.

    Zoning Ordinance §XXVIII ↗

  2. Newburyport Historical Commission decides whether to impose a delay

    Built c. 1707, so 75 or more years old: removing more than 25% of its exterior walls, changing the roofline (pitch, towers, cupolas, anything projecting above the roof), moving it, or adding a dormer that misses the setback and pitch rules is "demolition" under the demolition delay ordinance. The Commission holds a hearing within 30 days and may impose a delay of up to 18 months. In the DCOD the wall test goes to the Zoning Board instead; the Commission keeps roofline, roof pitch and dormer work. Parts of the building documented as younger than 75 years are excluded on a written determination by the Zoning Administrator.

  3. Zoning Administrator first stop

    Every project starts with a zoning determination from the Zoning Administrator, which says which of these reviews apply and whether the work also needs zoning relief (a special permit for a non-conformity, or a variance). Fees, forms and filing deadlines are on the City’s site.
