District of Columbia HOA ADUs & Modifications

Section 1: Overview

Start with the shape of the place. The District of Columbia runs on condominiums and cooperatives, and it treats accessory dwelling units (ADUs) as a zoning question. No District statute overrides a condominium or HOA covenant on ADUs.¹ The DC Condominium Act of 1976 (D.C. Code Chapter 19 of Title 42) governs condominiums, while cooperatives and the smaller number of HOAs answer to their recorded instruments and DC corporate law.^2,3 Whether an owner may add an ADU turns on two things—the zoning regulations and the declaration—and the question arises mostly for fee-simple rowhouses rather than condominium units.⁴ Solar and EV authority turn on the Condominium Act, the declaration, and any verified District provision, and only the solar statute currently reaches association covenants.^5,6 A layer of federal law binds every association regardless of what the District says: the Freedom to Display the American Flag Act covers the U.S. flag, the OTARD rule covers antennas and satellite dishes, the Fair Housing Act covers reasonable modifications for disability, and ADA Title III covers common-area facilities that serve as public accommodations.^7,8,9,10 The sections that follow lay out the legal framework, the compliance obligations it creates, recent activity, and where the District stands nationally.

Section 2: The legal framework

2A. Architectural review authority and the role of the instruments

For condominiums, architectural authority comes from two layers: the Condominium Act and the recorded condominium instruments—the declaration and the bylaws. The Act reaches every condominium created in the District, and a provision that takes effect after a condominium's creation does not invalidate an existing provision of that condominium's instruments.² The Act superseded the 1963 Horizontal Property Act.² The unit owners' association holds the power to adopt and amend bylaws, rules, and regulations, except where the instruments expressly prohibit it.¹¹ Board members owe a fiduciary duty: an officer or member of the executive board must exercise the care the law requires of a fiduciary of the unit owners.¹² A court reviews the association's decisions and actions under the business-judgment standard.¹³ So a reviewing court does not substitute its own aesthetic preference; it asks whether the board acted within its authority and in good faith. For cooperatives and HOAs, architectural authority sits in the instruments themselves. The DC Nonprofit Corporation Act (D.C. Code Title 29, Chapter 4) supplies the corporate formalities for the many associations organized as nonprofit corporations, and cooperative-housing law supplies the corporate framework for cooperatives.^3,14 The District has no comprehensive planned-community HOA statute.³ A typical architectural-review structure requires owners to submit plans to a board or committee, which approves or denies them under the declaration's standards.

2B. Protected modifications and federal overlays

The District has one covenant-voiding solar statute. D.C. Code § 8-1774.51, added by the Solar Expansion for Cooperative Associations Act of 2018 (D.C. Law 22-142, effective July 17, 2018), bars a homeowners association, a condominium owners association, and a cooperative housing association from prohibiting an owner or member from installing or using a solar energy collection device on the owner's property or residential unit, or on a roof that covers only that owner's unit—whether or not the roof is part of the common elements.^5,15 An association may still bar installation on common elements other than a single-owner roof, and it may set reasonable guidelines, other than aesthetic ones, to prevent a nuisance.⁵ Here is the condominium wrinkle: most condominium roofs are common elements, so a unit owner's protected installation generally has to sit on a roof covering only that owner's unit or within the owner's own property.⁵

On EV charging, the District does not yet limit condominium or HOA authority through an enforceable covenant-voiding statute. The Comprehensive Electric Vehicle Infrastructure Access, Readiness, and Sustainability Amendment Act of 2024 (D.C. Law 25-262) created a condominium and community-association right-to-charge provision at D.C. Code § 6-1451.03c,¹⁶ under which an association may not prohibit or unreasonably restrict installation of an EV charging port in an owner's deeded or designated parking space, with the owner covering installation and maintenance costs. But that provision carries a "Not Funded" label and has not taken effect, because § 7 of D.C. Law 25-262 ties it to the inclusion of the law's fiscal effect in an approved budget and financial plan.⁶ A separate measure, the Electric Vehicle Readiness Amendment Act of 2020 (D.C. Law 23-194, D.C. Code § 6-1451.03a), sets a make-ready construction mandate for new and substantially improved buildings; it is not a covenant-voiding right to charge.¹⁷

Federal law binds every association on top of all this. The Freedom to Display the American Flag Act of 2005 bars an association from restricting a member's display of the U.S. flag on property the member owns or has a right to use exclusively.⁷ The OTARD rule (47 C.F.R. § 1.4000) prohibits restrictions that impair covered antennas and satellite dishes in an owner's exclusive-use area.⁸ The Fair Housing Act requires the association to allow reasonable modifications for disability (42 U.S.C. § 3604(f)(3)).⁹ And ADA Title III governs common-area facilities that are public accommodations (42 U.S.C. § 12181 et seq.).¹⁰ Outside the solar statute and these federal overlays, the declaration and the Condominium Act control.

2C. ADUs: zoning and the declaration

ADUs are a zoning matter under the DC Zoning Regulations of 2016, administered by the Zoning Commission, the Office of Zoning, and the Board of Zoning Adjustment. Accessory apartments are permitted by right in most residential (R) zones under Subtitle U § 253, and they require a special exception from the Board of Zoning Adjustment in certain other zones.^4,18 The Rental Housing Act separately defines an accessory dwelling unit at D.C. Code § 42-3401.03(1) as a rental unit secondary to the principal single-family dwelling, with its own kitchen and bath.¹⁹ ADUs come up mostly for fee-simple rowhouses. No District statute overrides a condominium or HOA covenant on ADUs, so the analysis runs on two tracks: zoning permission for the lot, and the declaration's restrictions within the community. The declaration is the binding constraint inside a community, and zoning permission does not defeat a covenant. That is what separates the District from California (Civ. Code § 4751) and Colorado (HB 24-1152), where state law reaches HOA covenants to protect ADUs.

Section 3: Compliance obligations created by the framework

A. Architectural review process obligations

• Owners submit modification applications as the instruments require, and the board or committee reviews them against the declaration's standards. [INSTRUMENTS; BOTH]
• The board must act within its authority and in good faith, because a court reviews the association's decisions and actions under the business-judgment standard. [DISTRICT STATUTE, § 42-1902.09(b); CONDOMINIUMS]¹³
• Boards should issue written decisions and keep records, consistent with the fiduciary duty they owe owners. [DISTRICT STATUTE, § 42-1903.08(d); CONDOMINIUMS]¹²
• For cooperatives and HOAs, the same process obligations flow from the instruments and corporate law. [INSTRUMENTS; COOPERATIVES/HOAs]³

B. Modifications the association must permit

• The association may not restrict a member's display of the U.S. flag on the member's own property. [FEDERAL; BOTH]⁷
• The association may not impair installation of covered antennas and satellite dishes in the owner's exclusive-use area. [FEDERAL, OTARD, 47 C.F.R. § 1.4000; BOTH]⁸
• The association must permit reasonable modifications for disability at the resident's expense. [FEDERAL, 42 U.S.C. § 3604(f)(3); BOTH]⁹
• Common-area facilities that are public accommodations must comply with ADA Title III. [FEDERAL; BOTH]¹⁰
• The association may not prohibit protected solar installations on an owner's property or a single-owner roof. [DISTRICT STATUTE, § 8-1774.51; BOTH]⁵
• No enforceable District EV right-to-charge obligation exists yet, because § 6-1451.03c is marked "Not Funded." [DISTRICT STATUTE, not implemented; BOTH]⁶

C. ADU obligations and limits on authority

• No District statute requires a condominium or HOA to permit ADUs. [no statutory duty; BOTH]
• Zoning governs whether an ADU is allowed on the lot. [ZONING; fee-simple lots]⁴
• The declaration governs whether an ADU is allowed within the community, and it controls even where zoning would permit the unit. [INSTRUMENTS; BOTH]

D. Enforcement, dispute resolution, and appeal obligations

• Before levying a fine, the association must give notice and an opportunity to be heard as the Act and instruments require. [DISTRICT STATUTE, § 42-1903.08(a)(11); CONDOMINIUMS]¹¹
• Disputes proceed through the DC Superior Court at trial, with appeals to the DC Court of Appeals, the highest court of the District. [DISTRICT; BOTH]²⁰
• The District has no intermediate appellate court, and the federal courts—the U.S. District Court for the District of Columbia and the D.C. Circuit—form a separate system that is not the ordinary path for these disputes. [DISTRICT; BOTH]²⁰

Section 4: Recent legislative and judicial activity

A. Recent measures

Two recent measures shape modification rights most directly.

B. Recent rulings

One recent ruling sets the tone for how the District's highest court reads condominium enforcement procedure.

C. Active legislative debates

The Council's current attention sits with condominium insurance.

The funding status of the 2024 EV right-to-charge provision at § 6-1451.03c remains the open question for modification rights.

Section 5: National positioning and related coverage

The District is a condominium-and-cooperative jurisdiction with zoning-based ADUs and no HOA preemption of covenants. Its condominium framework is the Condominium Act plus the instruments; its cooperatives and smaller HOA sector run on recorded instruments plus DC corporate law. Unlike HOA-preemption states such as California (Civ. Code § 4751) and Colorado (HB 24-1152), the District has not enacted a statute that voids covenant restrictions on ADUs, and its HOA footprint is small next to condominiums and cooperatives. For a multi-state operator managing District condominiums, the practical implication is direct: the Condominium Act and the instruments control modifications, subject to the federal overlays and the single District solar statute.

Federal frameworks—the Freedom to Display the American Flag Act, OTARD, the Fair Housing Act, and ADA—apply to District associations regardless of the local framework.
