Solar for Columbia Heights rowhouses and condo flats
Many Columbia Heights rowhouses were built a whole block at a time, and many have since been split into flats. Both shape a solar job here: neighbors with near-identical roofs, and owners who share one roof between two or three units.

Short answer
Solar in Columbia Heights usually goes on flat rowhouse roofs behind the parapet, and earns full DC SRECs. Many houses here were built in rows by the same developer and many are now split into condo units, so we often design for a shared roof with separate meters, either as separate arrays or as one system under an owners' agreement.
The houses
Rows built together
In 1907, developer Harry Wardman began building blocks of rowhouses off 14th Street between Monroe Street and Spring Road, part of the roughly 3,000 residential buildings he put up across the city, most of them row houses. Houses built together tend to have matching roofs, parapets and hatches.
That makes neighbors' installs a useful guide: if the house next door has solar, its layout tells us a lot about yours. It also means shade from a taller addition next door can matter a great deal on a narrow roof.
Shared roofs
Two or three units, one roof
Many Columbia Heights rowhouses are now two or three condo units with separate meters sharing one flat roof. Owners can split the roof into separate arrays wired to each unit's meter, or share one system under an agreement. Separate arrays are cleaner on paper; a shared system can cost less per panel.
We draw both options and give the owners plain numbers before anyone decides.
How a job runs
Down 14th Street from our office
Our service office sits on 14th Street NW in 16th Street Heights, a straight run down 14th Street to Columbia Heights. After the roof and panel check come the design, any owners' agreement, the DC permit, the Pepco interconnection, installation, inspection and permission to operate.
Then we certify each system for DC SRECs, which sold for about $360 to $455 each in 2026.
