Condo Regime

Published by Department of Buildings | District of Columbia | Metadata Last Checked: February 19, 2026 | Last Modified: 2026-02-14T11:42:55.000Z
The Regimes are how Office of Tax and Revenue (OTR) quantifies units in a given condo development, grouping of condos. A condo regime number is assigned to each residential condo application or Article of Confederation regardless of how many buildings there are at any one site. The regime number starts with a 1, 2, or 3 depending upon where the condo is located and where they fall in the assessment process of Real Property Tax Assessment (RPTA). All numbers after the first are consecutive. RPTA maintains the master list of Regime numbers for residential properties. Commercial condos are not associated with a Regime number.Condo lots are individual lots for each condominium. The lot numbers normally range from 2000-6999. These condo lots are not geographically defined other than being within a air rights, record, tax or a combination of lots that has one or more condo buildings within it.
