The 7 Critical AP Style Rules For Washington D.C. Reporting That Journalists Get Wrong (Updated 2025)

The Associated Press (AP) Style Guide remains the definitive authority for journalistic writing in the United States, and nowhere is its precision more critical than when reporting on the nation’s capital, Washington, D.C. Given the city's unique status as a federal district and a hub of both national and local politics, the rules are constantly evolving to reflect current political and social realities, making adherence to the latest standards essential for credibility. This deep-dive guide, informed by the most recent updates to the Associated Press Stylebook, including the 57th Edition, clarifies the most common and critical style errors. As of December 2025, mastering these seven core rules ensures your copy is accurate, authoritative, and in line with current journalistic best practices when covering the District of Columbia.

The Core D.C. Style Rules: Capitalization, Abbreviation, and Punctuation

The fundamental rules for referencing the nation’s capital are the most frequently tested, especially the correct use of abbreviations and the necessary distinction from the state of Washington.

1. The Essential Abbreviation and Punctuation Rule

The primary rule for the District of Columbia centers on its abbreviation and the required punctuation. * Rule: Always use periods in the abbreviation: D.C.. * Context: The full name, *District of Columbia*, should be used on first reference if the context is formal or if space allows, but D.C. is acceptable in datelines and subsequent references. * Key Distinction: Never confuse the AP style abbreviation D.C. (with periods) with the two-letter postal code DC (without periods), which is reserved for mailing addresses and technical uses.

2. The Capitalization Update for "District"

A significant and recent update to the AP Stylebook addressed the capitalization of the word "District" on second reference, a change that acknowledges the growing political identity and local governance of the city. * Old Style: The word *district* was generally lowercase on second reference. * New Style: The word District can now be capitalized on second reference when referring to the federal district of Columbia, reflecting its status as a proper noun and a distinct entity. This update, made in a recent March stylebook revision, is crucial for showing respect to the city’s governmental structure.

3. Differentiating Washington, D.C. from Washington State

Clarity is paramount in news reporting, especially when a name is shared by a state and a federal district. * The Problem: When writing about Washington, the state, and Washington, D.C., the potential for confusion is high. * The Solution: Use Washington state or state of Washington when necessary to distinguish the state from the District of Columbia. * Dateline Use: In datelines, AP Style dictates using the city name followed by the state abbreviation for the state of Washington (e.g., SEATTLE, Wash.) and WASHINGTON alone for the federal district, or WASHINGTON (D.C.) if the context demands absolute clarity.

AP Style for Federal and Local D.C. Entities

Reporting on Washington D.C. means navigating the dual nature of its government—the federal agencies and landmarks that define the country, and the local municipal bodies that govern the city’s residents.

4. Capitalization of Federal Landmarks

The capitalization of D.C.’s most iconic buildings and public spaces is non-negotiable, always treating them as proper nouns. * The U.S. Capitol: Capitalize U.S. Capitol when referring specifically to the building in Washington, D.C., where the U.S. Congress meets. Use Capitol Hill when referring to the residential neighborhood surrounding the building. * The White House: Capitalize White House when referring to the building or the presidential administration that occupies it (e.g., *The White House announced...*). * The National Mall: Capitalize The National Mall or simply The Mall when referencing the prominent open-air park that stretches from the Capitol to the Lincoln Memorial. * The Pentagon: Always capitalize The Pentagon when referring to the building that houses the U.S. Department of Defense.

5. Referencing Local D.C. Government Officials

The District of Columbia has its own local government, complete with a Mayor and a City Council, which must be styled according to AP’s rules for legislative titles. * Mayor: Capitalize the formal title Mayor when it precedes a name (e.g., *Mayor Muriel Bowser*). It is lowercase when used alone or after a name (e.g., *The mayor signed the bill*). * D.C. Council: The full name of the legislative body, D.C. Council or District of Columbia Council, should be capitalized as a proper noun. * Councilmember: Use the title Councilmember (or Councilman/Councilwoman if specified by the individual) capitalized before a name (e.g., *Councilmember Jane Doe*), but lowercase in all other uses.

Navigating Evolving Political Terminology

The AP Stylebook is a living document, constantly adapting to political discourse. The ongoing movement for D.C. statehood presents a unique challenge for journalists seeking neutral and accurate language.

6. The AP Style Approach to D.C. Statehood

While the AP has not issued a specific, prescriptive style for the D.C. statehood movement, standard AP rules for political movements and legislation apply. * The Movement: Refer to it as the D.C. statehood movement or the movement for D.C. statehood. Avoid loaded or overly promotional language. * Legislation: Specific legislative proposals should be capitalized as proper names, such as the Washington, D.C. Admission Act or the New Columbia Statehood Initiative. * Proposed State Name: The proposed name for the 51st state has often been New Columbia or State of Washington, D.C. When reporting on these, treat them as the proper name of the proposed entity.

7. The Correct Use of "Federal District" and "Home Rule"

To provide topical authority and context, journalists frequently use the terms *federal district* and *home rule*. * Federal District: Use lowercase federal district as a descriptive term (e.g., *The city's status as a federal district is unique*). * Home Rule: The term home rule should be used in lowercase, referring to the local government’s limited self-governance authority granted by Congress.
