1508 Caroline Street: If Visible from Street, Then No

On January 29, DC's Historic Preservation Review Board (HPRB) rejected for a second time a proposed renovation of a brick duplex at 1508 Caroline Street NW in the U Street Historic District.

The property in November 2014

Caroline Street, just south of U Street between 15th and 16th Streets, is a row of identical duplex houses built around 1880. The group of houses have remained largely unmodified. The exception to this is the duplex home connected to 1508 Caroline Street, which got a third-story addition in 1888. The owner of this adjoining home bought 1508 Caroline Street and hoped to be able to add a pop-up to match the third story addition on the existing home (on the left of the photo).

The pop-up addition was endorsed by Advisory Neighborhood Commission (ANC) 2B/Dupont Circle (see SALM blog post of November 19, 2014). The HPRB rejected the plan as represented to the ANC in November. Last week's rejection was of a modified version of the plan, somewhat less visible from the street.

"Even this amount of visibility is not compatible," said HPRB member Nancy Metzger.

The original design called for a two-story rear addition, a one-story side addition, and a basement entrance, as well as the third-story pop-up. HPRB staff accepted all elements except the pop-up -- see November 2014 staff report here. The Board accepted the staff report in a 4-3 decision, reported on page two of a four-page document here.

The owner and designer tried once again to get some addition to the height of the building approved. The new version of the design was set back 21 feet from the front and 4 feet from the side of the building. However, because this building (and all of the buildings on Caroline Street) are detached from their neighbors, the addition will still be visible from the street in front of the house. This did not seem to bother the architect designer.

"I think this won't really effect the aesthetic of the neighborhood," he told the board.

The HPRB asked the architect designer if he had conducted a "flag test" (see description on page three of document here), in which the applicant for HPRB approval sets up flags on the top of a building to demonstrate the dimensions of a proposed expansion and then invites HPRB staff to view the flags. The architect designer had not.

The board voted unanimously to accept a new staff report, which (like the November 2014 staff report) found the project to be "incompatible with the historic district". The Board told the owner and his architect designer that, should they decide to come back again, they were more likely to receive approval if they performed a flag test which demonstrated that planned modifications of the house would not be visible from the street.

I did not attend this meeting. I gathered the information for this report by watching a portion of the archived video of the January 29 meeting at the HPRB web site here. The portion of the meeting dealing with this property starts at time 1:41:23.

1508 Caroline Street: ANC Says Popup OK, Just This Once

Advisory Neighborhood Commission (ANC) 2B/Dupont Circle voted unanimously to endorse a request to add two additional stories on a residence on Caroline Street NW, one of which will be visible from the street. The unanimous endorsement occurred at the ANC's regular monthly meeting on November 12.

The aim is to make it symmetrical-looking from the street.

At the meeting, and in the resolution subsequently approved by the ANC (see text halfway down the page here), it was emphasized that this property had a unique situation and the approval of additional stories should in no way be construed as setting a precedent for the neighborhood.

Caroline Street is runs one block from 15th Street to 16th Street, just south of U Street. With the exception of 1508 Caroline Street, it is made of matching pairs of two-story houses, constructed at the same time in the 1880s.

A third story was added on 1508 Caroline Street sometime before 1900. This makes it the only three-story building on the block, and the only building on the block which does not match its next-door neighbor.

The new owner of 1508 Caroline Street has also owned 1506 Caroline Street next door since 1989. He told the ANC he had meet with neighbors two weeks ago to brief them on his plans for the renovation and expansion. It includes a complete interior renovation and the removal of the chain link fence in front of the house, which the owner believed was the last chain link fence in the neighborhood.

HRPB placarding on the property

The owner said the basement will also be excavated to create a basement apartment. The apartment will have a side entrance which will not be visible from the street.

On top of the new third floor, built to match its neighbor, there will be a fourth floor, set back nine feet two inches from the front of the third floor.

Tom Bauer, President of the Dupont Circle Conservancy, testified that his group intended to endorse the "unique semidetached" project. The renovation would make the pair of buildings look more consistent and historic.

"This third story should not set a precedent," Bauer said.

The owner of neighboring 1510 Caroline Street asked about the time of day when construction would take place. The owner said construction work would generally take place during normal working hours with "rare" weekend work.

Since the building is in the U Street Historic District, the renovation and expansion must get the approval of the Historic Preservation Review Board (HPRB). Consideration of the project on the HPRB's agenda for its next pair of meetings, the first of which is on November 20.

However, the proposed matching third-story popup on the front of 1508 Caroline Street has not been viewed favorably by HPRB staff -- see report here. The rest of the project, including the two-story rear addition and the basement alterations, raised no objections.

Online records show this building was last sold in July 2014 for $725,000.
