Section 1: Overview

Delaware is a modern Uniform Common Interest Ownership Act state, and here is what that means on the ground: county and municipal zoning govern accessory dwelling units (ADUs), and no Delaware statute overrides an HOA or condominium declaration that bars them. Communities created after September 30, 2009 answer to the Delaware Uniform Common Interest Ownership Act (DUCIOA), codified at 25 Del. C. ch. 81 (§ 81-101 et seq.).¹

Older condominiums recorded under the Unit Property Act, 25 Del. C. ch. 22 (§ 2201 et seq.), stay under that Act,² and preexisting communities pick up the enumerated DUCIOA sections only for events and circumstances that occur after the effective date.¹ Whether an owner may actually build an ADU turns on two things: county or municipal zoning — New Castle, Kent, and Sussex counties, plus municipalities such as Wilmington^3,4 — and the recorded declaration, which is the binding constraint inside an HOA or condominium.

Authority over solar and electric-vehicle (EV) charging runs through the declaration and the DUCIOA framework, with one important exception: a Delaware statute voids covenants that restrict solar energy systems (25 Del. C. § 318).⁵ Several federal overlays bind every association regardless of state law — the Freedom to Display the American Flag Act of 2005,⁶ the FCC OTARD rule for antennas and satellite dishes,⁷ the Fair Housing Act's reasonable-modification requirement,⁸ and ADA Title III for common-area facilities that operate as public accommodations.

The sections that follow lay out the framework, the compliance obligations it creates, and the recent activity in the legislature and the courts.

Section 2: The legal framework

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

Delaware has no standalone statewide architectural-review statute, so the authority sits in the recorded declaration, read against the DUCIOA framework. Under 25 Del. C. § 81-302(a), a unit owners' association must adopt bylaws and may adopt rules, and § 81-302(a)(16) lets the association exercise all other powers that legal entities of the same type may exercise in this State.⁹ Section 81-320(b) sets the condition: if the declaration reserves the right under § 81-302(a)(16), the association may adopt rules to establish and enforce those standards — and once it does, it must also adopt procedures for enforcement and for approving applications, including a reasonable time within which the association must act after an owner submits one.

Section 81-320(a) requires the executive board to notify every unit owner before it adopts or substantially amends a rule, and to hold a meeting to take comments. For communities created before September 30, 2009 under the Unit Property Act, a recorded code of regulations governs administration (25 Del. C. § 2206), and the council may adopt, alter, amend, and repeal that code and issue rules governing use of the property, subject to a majority of unit owners' right to change those actions (25 Del. C. §§ 2207, 2211).¹⁰ Preexisting communities pick up specified DUCIOA sections only for events and circumstances after the effective date (25 Del. C. § 81-119), and where neither the governing documents nor the Unit Property Act speaks to an issue, DUCIOA controls.¹

When a dispute reaches court, the judge asks a straightforward set of questions: is the restriction enforceable, did the association apply it in a way that is not arbitrary or capricious, and did the owner violate it? Delaware courts treat design covenants as "neither new nor uncommon in Delaware" but warn that they "must be carefully evaluated because their arguably subjective nature introduces the risk of arbitrary and capricious application" (RBY&CC East Side Homeowners Association, Inc. v. Beebe, Master's Final Report, June 9, 2023).¹¹ Covenant-enforcement and injunctive matters usually proceed in the Court of Chancery, which sits in equity.¹²

2B. Protected modifications and federal overlays

On solar, Delaware does more than record easements — it voids covenants. Under 25 Del. C. § 318(b), any covenant, restriction, or condition that effectively prohibits or unreasonably restricts an owner from installing or using a roof-mounted solar energy system is void and unenforceable; for ground-mounted systems, the statute instead lets owners amend restrictive covenants to allow them by a majority vote (25 Del. C. § 318(e)(3)).⁵ The statute still preserves reasonable restrictions — those that do not significantly raise the system's cost or significantly cut its efficiency or specified performance (25 Del. C. § 318(c)) — and it expressly reaches declarations under the Unit Property Act. A separate provision, the Delaware Energy Act at 29 Del. C. § 8060, also addresses solar restrictions imposed by counties, municipalities, and associations.¹³

On EV charging, the picture changes: Delaware has no statute voiding HOA or condominium covenants over EV charging stations. The state addresses EV charging through building-code requirements for new construction (16 Del. C. ch. 80)¹⁴ and a municipal-permitting statute for residential installations in municipalities of 30,000 or more (22 Del. C. § 119), but neither one overrides an association's covenant the way the solar statute does.

The federal overlays bind every association: the Freedom to Display the American Flag Act of 2005 (Pub. L. 109-243, 4 U.S.C. § 5 note) bars an association from restricting a member's display of the U.S. flag on property the member separately owns or exclusively uses; the FCC OTARD rule (47 C.F.R. § 1.4000) bars restrictions that impair the installation, maintenance, or use of covered antennas and satellite dishes in the user's exclusive-use area; the Fair Housing Act (42 U.S.C. § 3604(f)(3)(A)) requires the association to permit reasonable modifications at the resident's expense where they are necessary for full enjoyment of the premises; and ADA Title III (42 U.S.C. § 12181 et seq.) reaches common-area facilities that operate as public accommodations.^6,7,8 That resident-funded modification duty is distinct from the FHA's new-construction accessibility mandate (42 U.S.C. § 3604(f)(3)(C)), which requires covered multifamily buildings first occupied after March 13, 1991 — including newly built ADUs that qualify as covered units — to include accessible routes, usable doors, and reinforced bathroom walls at construction; DOJ continues to enforce that standard against builders, most recently in a Brooklyn consent decree requiring retrofits and penalties.¹⁵ Where Delaware has not enacted a covenant-voiding protection, the declaration and the DUCIOA framework control, subject to these federal overlays.

2C. ADUs: county and municipal zoning and the declaration

ADUs in Delaware answer to county zoning (New Castle, Kent, and Sussex counties) and municipal zoning, and the rules vary by jurisdiction. New Castle County addresses accessory dwelling units in its Unified Development Code (Chapter 40 of the county Code), which sets lot-area, setback, and size standards.³ Kent County went further and adopted a dedicated ADU chapter (Chapter 101 of the Kent County Code) that permits ADUs in every residential zone, subject to conditions that include owner-occupancy of one unit on the property.⁴

No Delaware statute overrides HOA or condominium covenants for ADUs, so the analysis runs in two layers: zoning permission at the county or municipal level decides whether the lot may host an ADU, and the recorded declaration decides whether an owner inside a common interest community may build one — with the declaration as the binding constraint. That sets Delaware apart from states that preempt HOA covenants.

California Civil Code § 4751(a) makes any governing-document provision that "either effectively prohibits or unreasonably restricts the construction or use of an accessory dwelling unit or junior accessory dwelling unit on a lot zoned for single-family residential use … void and unenforceable," and Colorado's HB 24-1152 similarly reaches HOA covenants. Delaware has passed no equivalent covenant-voiding ADU statute, so an association's declaration may lawfully prohibit or restrict ADUs inside the community even where county zoning would allow one on the lot.

Section 3: Compliance obligations created by the framework

A. Architectural review process obligations

• Application and submission: An association that adopts construction and design criteria under a declaration reservation must also adopt procedures for approving applications, including a reasonable time within which it must act after submission (STATE STATUTE, 25 Del. C. § 81-320(b); post-2009 DUCIOA communities).⁹
• Decision standard and rulemaking notice: Before the executive board adopts or substantially amends a rule, it must notify every unit owner and hold a meeting to take comments (STATE STATUTE, 25 Del. C. § 81-320(a)).⁹
• Written decisions and consistency: A reviewing court asks whether restrictions are enforceable and whether the association applied them without arbitrariness or caprice, so document decisions and apply them consistently (DECLARATION, read against DUCIOA).
• Recordkeeping: Associations must keep specified records at the principal office (STATE STATUTE, 25 Del. C. § 81-318).⁹
• For pre-2009 Unit Property Act communities, review authority comes from the recorded code of regulations and rules (DECLARATION / 25 Del. C. §§ 2206, 2207, 2211).¹⁰

B. Modifications the association must permit

• U.S. flag display (FEDERAL, Freedom to Display the American Flag Act of 2005, Pub. L. 109-243; and STATE STATUTE, 25 Del. C. § 316, plus 25 Del. C. § 81-320(c) for DUCIOA communities): the association may not prohibit display of the U.S. flag within the member's separate ownership or exclusive-use area, subject to reasonable size and placement rules.^5,6
• Antennas and satellite dishes (FEDERAL, OTARD, 47 C.F.R. § 1.4000): the association may not impair installation, maintenance, or use of covered devices in the user's exclusive-use area.⁷
• Disability-related modifications (FEDERAL, FHA, 42 U.S.C. § 3604(f)(3)(A)): the association must permit reasonable modifications at the resident's expense where they are necessary for full enjoyment of the premises.⁸
• Common-area public accommodations (FEDERAL, ADA Title III, 42 U.S.C. § 12181 et seq.).
• Solar energy systems (STATE STATUTE, 25 Del. C. § 318): covenants that effectively prohibit or unreasonably restrict roof-mounted solar are void and unenforceable, subject to reasonable restrictions, and covenants restricting ground-mounted solar may be amended by a majority vote of owners; this reaches both DUCIOA and Unit Property Act declarations.⁵

C. ADU obligations and limits on authority

• No Delaware statute requires an HOA or condominium to permit an ADU inside the community, and none voids covenants that restrict them (DECLARATION controls; contrast California Civ. Code § 4751 and Colorado HB 24-1152).
• County or municipal zoning governs whether the lot may host an ADU (LOCAL ZONING; e.g., New Castle County UDC Chapter 40; Kent County Code Chapter 101).^3,4
• The two-layer result: inside a common interest community, an owner needs both zoning permission and a declaration that does not prohibit the ADU. This holds for both post-2009 DUCIOA and pre-2009 Unit Property Act communities.

D. Enforcement, dispute resolution, and appeal obligations

• Notice and opportunity to be heard: after notice and an opportunity to be heard, an association may levy reasonable fines for violations of the declaration, bylaws, and rules (STATE STATUTE, 25 Del. C. § 81-302(a)(11); post-2009 communities), with the rest of the process as the declaration provides.⁹
• Dispute resolution: the Common Interest Community Ombudsperson in the Department of Justice provides education and alternative dispute resolution and requires associations to adopt an internal dispute resolution process (STATE STATUTE, 29 Del. C. subch. IV, §§ 2543-2546); the Ombudsperson does not adjudicate architectural decisions and is not counsel to any party.¹⁶
• Mandatory mediation: an association and a homeowner must mediate a dispute over enforcement of deed covenants or restrictions in the Court of Chancery, with trial before a Magistrate in Chancery and fees shifting to the prevailing party (STATE STATUTE, 10 Del. C. § 348).¹⁷
• Trial and appeal: covenant-enforcement and injunctive matters proceed in the Court of Chancery; actions at law for money damages proceed in the Superior Court (smaller claims in the Court of Common Pleas or the Justice of the Peace Court); and appeals from both go directly to the Delaware Supreme Court — the only appellate court, because Delaware has no intermediate appellate court.^12,18

Section 4: Recent legislative and judicial activity

Delaware's recent HOA-adjacent activity is modest. One bill and two rulings do most of the work of showing where the state is headed on ADUs and architectural enforcement.

A. Recent bills

B. Recent rulings

C. Active legislative debates

The session's most active HOA-adjacent proposal was SB 87, which would have required local governments to permit ADUs and would have limited covenants restricting ADUs on single-family lots on a forward-looking basis. Contested on local-control and HOA-autonomy grounds, it died without a floor vote when the General Assembly adjourned sine die on June 30, 2026.¹⁹ The housing measure that did pass, Senate Substitute 2 for Senate Bill 23 (the Housing for Every Delawarean Act, 85 Del. Laws c. 343, signed July 13, 2026), contains no occurrence of “covenant,” “declaration” or “deed restriction,” and the 153rd General Assembly enacted no covenant preemption of any kind.²¹

Section 5: National positioning and related coverage

Delaware adopted a modern (2008) version of the Uniform Common Interest Ownership Act, effective September 30, 2009, and it places architectural authority in the recorded declaration rather than in a standalone review statute. On ADUs, Delaware has not preempted HOA or condominium covenants: unlike California (Civil Code § 4751) and Colorado (HB 24-1152), which void governing-document restrictions on ADUs, Delaware leaves the declaration controlling inside a community while county and municipal zoning govern the lot.

On solar, Delaware does void covenants that restrict solar energy systems (25 Del. C. § 318), which puts it among the states with solar-access protections.⁵ The court structure is distinctive: covenant-enforcement and injunctive matters run through the Court of Chancery, money-damages actions through the Superior Court, and appeals from both go straight to the Delaware Supreme Court, with no intermediate appellate court.^12,18

Delaware's HOA footprint is smaller than that of the larger UCIOA states, and its HOA-specific legislative volume is modest. For a multi-state operator, the practical implication is blunt: a covenant-enforcement playbook built for a preemption state does not carry over. In Delaware the declaration remains the primary constraint on ADUs, and disputes route through equity in the Court of Chancery. The federal frameworks — the Freedom to Display the American Flag Act, the FCC OTARD rule, the Fair Housing Act, and ADA Title III — apply to every association regardless of state law.^6,7,8

Recommendations

Stage 1 — Immediate (all associations):

• Which statute governs a community — DUCIOA (created after September 30, 2009) or the Unit Property Act (older opt-in condominiums), and whether a preexisting community has opted into any DUCIOA sections — determines which architectural-authority provisions apply.
• Under § 81-320(b), design-standard rules depend on a declaration reservation of the right under § 81-302(a)(16), and an association that adopts such rules must also adopt procedures for approving applications, including a reasonable time within which it must act.
• Under 25 Del. C. § 318, a covenant that effectively prohibits roof-mounted solar is void, and only "reasonable restrictions" survive — those that do not significantly increase the system's cost or significantly decrease its efficiency or specified performance.

Stage 2 — Near-term (process discipline):

• Courts ask whether a restriction was applied consistently and without arbitrariness. The enforceability-and-non-arbitrary-application standard in Beebe and Yu v. Cahill rewards contemporaneous documentation.
• Four federal overlays apply to architectural review: U.S. flag display, OTARD antennas, FHA reasonable modifications (resident-paid), and ADA Title III common areas. These override any contrary covenant.
• The Common Interest Community Ombudsperson framework requires associations to maintain an internal dispute resolution process (29 Del. C. subch. IV).

Stage 3 — Watch items and thresholds that would change the analysis:

• ADUs: SB 87, which would have voided covenants restricting ADUs if created or taking effect after June 30, 2027, died at sine die on June 30, 2026. Recorded covenants restricting ADUs stay enforceable, and county or municipal zoning plus the declaration both govern.
• EV charging: If Delaware enacts a covenant-voiding EV-charging statute that reaches associations — as several neighboring states have — shift from full board discretion to a reasonable-restriction or deemed-approval model. No such statute exists today, so the declaration controls EV charging for now.
• Litigation posture: Because deed-restriction disputes carry mandatory Chancery mediation and § 348(e) fee-shifting, weigh settlement value early. A losing enforcement position can carry the other side's fees.

Caveats

• SB 87 was reported out of committee May 7, 2025 and died without a floor vote when the 153rd General Assembly adjourned sine die on June 30, 2026. Delaware's General Assembly runs two-year sessions, so the bill did not carry over.
• The § 318 solar statute preserves "reasonable restrictions," and what counts as reasonable is fact-specific; the statute voids only covenants that effectively prohibit or unreasonably restrict solar.
• County and municipal ADU treatment varies. This page cites New Castle County (UDC Chapter 40) and Kent County (Code Chapter 101); Sussex County and individual municipalities such as Wilmington and Newark set their own zoning, which varies lot by lot.
• Beebe is cited here at the trial level (Chancery Master's Final Report, June 9, 2023); this page does not analyze any later appellate disposition.
• The Freedom to Display the American Flag Act contains no private right of action and works chiefly as a prohibition on association policies.
• This page is regulatory intelligence, not legal advice. Community-specific outcomes depend on the exact declaration language, the community's formation date and statute, and the county or municipality involved.
