Varnum Building
Also known as: United Building

Why it's listed
Standing at the corner of Bridge and Third Streets, this four-story wood-frame building was completed in 1882 by brothers Daniel and Leavitt R.J. Varnum, who bought the lot at auction after the death of an earlier resident. It holds two ground-floor stores and twelve apartments above. A clipped corner bay topped by a square tower with a steep slate roof makes it a landmark near the Central Bridge. Slate-clad hoods, iron cresting, turned brackets and paneled pilasters show its Queen Anne character. The Varnums ran their real estate office here and helped develop much of Centralville, the largely residential area across the Merrimack River from the textile mills. Grocers and later a drugstore occupied the corner shop, and the building was sold out of Varnum hands in 1923. It was rehabilitated in 1985-86 and renamed the United Building. It is listed for its architecture and its role in the neighborhood's commercial and real estate growth.
Significance in brief: The nomination argues the building is significant under Criterion A for its link to major real estate development in Centralville by the Varnum brothers. It is significant under Criterion C as a well-preserved Queen Anne commercial building with tenements above, rich in detail such as slate hoods, iron cresting, turned brackets and a corner tower. It is considered probably the oldest intact commercial storefront in this part of Lowell.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
