Delaware HOA Architectural Review

Quick-Reference Architectural Authority Table

Section 1: Overview — How architectural review works in Delaware

Delaware governs its common interest communities under the Delaware Uniform Common Interest Ownership Act — DUCIOA, 25 Del. C. Chapter 81 — a statute the legislature built on the 2008 revision of the Uniform Common Interest Ownership Act. DUCIOA backs the recorded declaration with association powers and a good-faith obligation, but it imposes no statutory architectural-review process.¹ Architectural authority sits chiefly in the declaration, which hands review to the board or an architectural review committee; DUCIOA supplies the association's power to adopt and enforce construction, design, and aesthetic rules when the declaration reserves that right, and it applies to communities created after September 30, 2009, while many older condominiums still answer to the Unit Property Act, 25 Del. C. Chapter 22.² Decision timelines, deemed-approval outcomes, and written-denial requirements are declaration and rule terms in Delaware, not statutory mandates — though an association that adopts design rules must build a reasonable time to act into its own procedures.³ The state carve-outs on architectural control are narrow: a solar provision that voids covenants unreasonably restricting owner-owned roof solar systems, a flag-display provision, and a limited "for sale" sign right, all layered over federal overlays.⁴ The dispute path stands out: covenant enforcement that seeks an injunction runs through the Court of Chancery with a mandatory mediation step, and appeals go straight to the Delaware Supreme Court, because Delaware has no intermediate appellate court.⁵ The sections below lay out the framework, the compliance obligations, and recent activity.

Section 2: The architectural-review framework

2A. Source and scope of architectural authority

Architectural control in Delaware starts in the recorded declaration, which typically delegates review of exterior changes to the executive board or an architectural review committee. DUCIOA reinforces that private arrangement; it does not replace it. Under 25 Del. C. § 81-320(b), if the declaration reserves the right, the association may adopt rules that establish and enforce construction and design criteria and aesthetic standards — and if it does, it must also adopt procedures for enforcing those standards and for approving applications.³ The association's general powers, including the power to adopt and amend rules, appear at 25 Del. C. § 81-302.⁶

Applicability turns on age and size. DUCIOA governs common interest communities that Delaware created after the effective date of September 30, 2009.² For communities created before that date, 25 Del. C. § 81-119 applies an enumerated list of DUCIOA sections, but only to events and circumstances that occur after the effective date, and it does not invalidate existing declaration provisions that do not conflict with the chapter.⁷ Condominiums created before DUCIOA generally remain under the Unit Property Act, 25 Del. C. Chapter 22.⁸ A condominium or cooperative with no more than 20 units, not subject to development rights that would push it past 20, answers only to 25 Del. C. § 81-106 (local ordinances) and § 81-107 (eminent domain) unless its declaration adopts the entire chapter.⁹ The order of precedence runs from DUCIOA's non-variable provisions, to the declaration, to the bylaws, and then to rules and architectural guidelines.⁷

2B. The approval process and standards of review

DUCIOA imposes no statutory application deadline, no deemed-approval rule, and no mandatory written-denial requirement for architectural applications. Those protections, where they exist, come from the declaration and the rules. The one statutory process requirement is indirect: an association that adopts design and aesthetic rules must write into its own procedures a reasonable time within which it must act after an owner submits an application.³ The number of days, and any deemed-approval consequence, come from the association's adopted rules — not from the Code.

The governing standard for discretionary decisions is the statutory good-faith obligation at 25 Del. C. § 81-113, which provides that every contract or duty the chapter governs carries an obligation of good faith in its performance or enforcement.¹⁰ DUCIOA also constrains enforcement discretion directly: 25 Del. C. § 81-302(f) lets the board use reasonable judgment about whether to pursue a violation, but bars the board from acting arbitrarily or capriciously when it takes enforcement action.¹¹ Delaware courts enforce recorded restrictions, but they read them against the drafter and require consistent application. The practical effect: uniform enforcement of published standards lowers litigation risk, while selective or arbitrary denials invite challenge. The operative rulebook, then, is the declaration plus any adopted architectural guidelines — and enforcing a denial through the courts may require a Court of Chancery mediation step before a judge reaches the merits.⁵

2C. Statutory and federal limits on architectural authority

Delaware's state carve-outs are narrow and specific. The solar provision, 25 Del. C. § 318, voids and makes unenforceable any covenant that effectively prohibits or unreasonably restricts an owner from installing or using a roof-mounted solar system. But it defines the covered "roof" to exclude roofs designated as common elements or common property and roofs the association, rather than the owner, must maintain, and it preserves reasonable restrictions that neither significantly raise cost nor cut efficiency, or that allow a comparable alternative.⁴ The statute sets up a notice-and-input process: an owner who intends to install sends notice at least 60 days in advance, and the association or maintenance corporation may offer placement input consistent with a reasonable restriction no later than 30 days before installation.⁴ This is not a blanket override of association covenants, and it does not reach association-owned or association-maintained roofs.

The flag provision, 25 Del. C. § 316, bars restrictions that prohibit display of the U.S. flag up to 3 feet by 5 feet on a flagpole up to 25 feet that meets setback requirements.¹² Within DUCIOA communities, 25 Del. C. § 81-320(c) adds that a rule may not prohibit display of the U.S. flag, the state flag, or signs about candidates for public office or ballot questions unless the declaration provides otherwise, though the association may still regulate time, place, size, number, and manner; the same section protects a "for sale" sign up to 12 inches by 18 inches.¹³ Delaware confirms no statutory carve-out for drought-tolerant or native landscaping, EV charging stations, rainwater harvesting, clotheslines, or religious displays; those remain declaration matters. Federal overlays add to the picture: the Freedom to Display the American Flag Act, the FCC OTARD rule at 47 C.F.R. § 1.4000,¹⁴ and the Fair Housing Act reasonable-modification right at 42 U.S.C. § 3604(f)(3)(A).

Section 3: Compliance obligations in the architectural-review process

A. Adopting and maintaining architectural standards

An association's authority to adopt construction, design, and aesthetic standards is statutory under DUCIOA, but conditional: 25 Del. C. § 81-320(b) permits those rules only if the declaration reserves the right, and it requires the association to also adopt enforcement and application-approval procedures.³ Before it adopts or substantially amends any rule, the board must notify owners and hold a meeting to take comment — a statutory step under 25 Del. C. § 81-320(a) — and every rule must be reasonable.⁶ For pre-2009 communities and small communities, this authority may rest on the declaration rather than DUCIOA.⁹

B. Reviewing and deciding applications

The duty to decide an application within a set time, to issue a written decision, or to give written reasons for a denial is declaration-based in Delaware; no statute imposes those steps. The related statutory obligations are narrower: adopted design rules must include a reasonable time to act under 25 Del. C. § 81-320(b), and discretionary decisions stay bounded by the good-faith duty at 25 Del. C. § 81-113 and the bar on arbitrary or capricious enforcement at 25 Del. C. § 81-302(f).¹¹

C. Honoring statutory and federal owner protections

Honoring the solar provision is statutory under 25 Del. C. § 318, including the reasonable-restriction limit and the notice-and-input timeline.⁴ Honoring flag and sign rights is statutory under 25 Del. C. § 316 and § 81-320(c).¹³ The federal protections stand on their own and add to state law: the Freedom to Display the American Flag Act, the OTARD rule at 47 C.F.R. § 1.4000 for covered antennas one meter or less in an exclusive-use area, and the Fair Housing Act reasonable-modification right, which the owner funds and which stays subject to reasonableness.¹⁵

D. Enforcement and dispute resolution

Fining for a violation is statutory under 25 Del. C. § 81-302(a)(11), which permits reasonable fines only after notice and an opportunity to be heard.¹⁶ Enforcing an architectural violation through the courts means the Court of Chancery, which hears covenant-enforcement claims that seek injunctive relief, and 10 Del. C. § 348 imposes a mandatory mediation step — administered through a Magistrate in Chancery, with proceedings confidential and off the public record — before a trial can proceed.⁵ The non-prevailing party at a § 348 trial generally pays the prevailing party's attorney fees and costs.⁵

Section 4: Recent legislative and judicial activity

4A. Recent bills

Delaware's legislature has not rewritten its architectural-review rules, but one housing measure now moving through the General Assembly would limit what an association can prohibit.

4B. Recent rulings

Two recent Court of Chancery decisions show how Delaware enforces architectural covenants — and how far a court will go to back them up.

4C. Active legislative debates

The most relevant active proposal touching architectural authority is SB 87, which would limit an association's power to prohibit accessory dwelling units; we found no enacted 2024-2026 measure that alters DUCIOA's architectural, solar, or flag provisions.¹⁷

Section 5: National positioning and related coverage

Delaware is a 2008-UCIOA state with a full governance framework but narrow owner-protective carve-outs, which sets it apart from 1982-UCIOA states such as Alaska, Colorado, and Connecticut. Its most distinctive feature is procedural: covenant enforcement that seeks an injunction runs through the Court of Chancery with a mandatory mediation step under 10 Del. C. § 348, and appeals go straight to the Delaware Supreme Court, because the state runs no intermediate appellate court.²⁰ For multi-state operators, the practical implication is straightforward: the declaration governs the architectural process, the statutory carve-outs stay narrow, and enforcement runs through a specialized equity court rather than a general civil court.⁵ That contrasts with carve-out-heavy states such as California and Colorado, which impose statutory landscaping, EV, and solar mandates that Delaware does not.

HOA Weekly's Delaware Architectural Review coverage updates quarterly as the General Assembly and the Delaware courts act. Federal frameworks — including the Freedom to Display the American Flag Act, the FCC OTARD rule, and the Fair Housing Act — apply to Delaware associations in addition to DUCIOA.
