Channel Square drew citywide attention after the landlord had a tenant arrested in the lobby of her own building while she was hosting a tenant association meeting. By then the landlord already had 185 citations on record across 24 buildings. DOB has since closed 179 of them, but a closed citation only means DOB stopped tracking it. Tenants in the building say many of the problems are still there.
See landlord profile → DC's largest housing judgmentTenants at Marbury Plaza lived for years with mold in 96% of units, rodent infestations, and no heat or hot water — while the landlord ignored court orders to make repairs. In November 2025, DC's Attorney General won DC's largest-ever housing judgment: $41M against the former owners, including $29.8M returned directly to tenants. A tenant organizing victory years in the making.

Ranked by fines on open violations, as assessed by DC's Department of Buildings. Not all fines are collected. Owners are matched to companies through DC's beneficial owner records, a current snapshot, so a company sold since a citation shows its current owners. Under DC law a beneficial owner is anyone holding more than 10% of a company, or anyone who controls its decisions or runs its day-to-day operations. Companies report this themselves and DC doesn't verify it. Each person or organization is credited with the fines of every company that lists them as a beneficial owner, since DC's records don't say how much of a company each owner holds. Co-owners' totals overlap, so the combined figures above count each violation once. A landlord may appear here because of open violations across multiple buildings, some cited years ago. DC Housing Authority (DCHA) is excluded. Inspired by the NYC Public Advocate's Worst Landlord Watchlist.
