Kalorama is two separately designated historic districts split by Connecticut Avenue: Sheridan-Kalorama, designated in 1989, and Kalorama Triangle, designated in 1987.
A listing that says Kalorama has not yet told you which Kalorama. The name covers two separate District historic districts with separate nominations, separate boundaries and separate lists of contributing buildings, and Connecticut Avenue runs between them. Sheridan-Kalorama, west of the avenue, was designated in 1989 with a period of significance from 1890 to 1945. Kalorama Triangle, east of it, was designated in 1987 with a period of significance from 1893 to 1939. They are not two halves of one thing. They are two districts that share a word, and the housing on either side is not the same product or the same price argument.
This is the detached side: large houses and mansions on generous lots, many of them in chancery use by foreign missions. That institutional occupancy is the structural fact of the submarket. It removes a meaningful share of the buildings from residential sale indefinitely, thins the comparable set to a handful of trades a year, and means a sale here is usually argued building by building rather than from a set of recent comparables. Designated in 1989, with a period of significance of 1890 to 1945, the district is under Historic Preservation Review Board and Historic Preservation Office review for exterior work visible from public space.
The Triangle is attached and vertical: rowhouses and early-twentieth-century apartment buildings, designated in 1987 with a period of significance of 1893 to 1939. A large share of the for-sale inventory here is therefore a unit rather than a whole building, which puts the resale documents at the centre of the diligence — instruments, association certificate, budget and reserve study. D.C. Code § 42-1904.11 gives the seller of a condominium unit until the tenth business day after contract to deliver them, and gives you three business days to cancel after they arrive. Confirm whether the building is a condominium or a cooperative before you budget anything, because the recordation schedule differs sharply between the two.
Because each district has its own nomination and its own contributing list, the two questions a renovation depends on — which district is this in, and is this building contributing — must be answered from the Historic Preservation Office record for the specific address. Neither district is a homeowners association: there is no private assessment and no architectural committee, and the authority is entirely public. Our Washington, DC page sets out the review mechanism, including the 120-day finding under D.C. Code § 6-1107(c) and the reversed presumption on demolition under § 6-1104, where no permit issues unless the Mayor finds it necessary in the public interest or finds unreasonable economic hardship.
Kalorama straddles a boundary area where the in-boundary assignment is address-specific rather than uniform across the name, and DCPS has been operating temporary feeder arrangements in nearby parts of Wards 1 and 2 in recent school years. Rather than print an assignment that may not apply to the house in front of you, the honest instruction is to run the exact address through the DCPS boundary tool for the school year in question, and to re-check it if you are buying against a year that has not yet started. As of August 2026 that is the only reliable way to answer it.
