Delaware HOA Water Conservation

Section 1: Overview — How water conservation interacts with HOA authority in Delaware

Delaware has no statute limiting an association's authority over water-efficient landscaping. Search Title 25, including the Delaware Uniform Common Interest Ownership Act, or DUCIOA, and no provision protects drought-tolerant or xeriscape landscaping, native or low-water plantings, artificial turf, water-efficient irrigation, rainwater harvesting, or graywater reuse against association restriction.¹ For a Delaware community, water-related landscaping rules come from the recorded declaration and the association's architectural-control process, with DUCIOA supplying the general framework for rulemaking and enforcement, the nonstock corporation formalities that apply to associations organized as nonprofits, and any applicable local water-utility rules.^2,5

State water-resource law is a separate body of law entirely. Delaware's riparian, eastern-state doctrine and DNREC's allocation and well permitting govern who may withdraw water and how much, and neither bears on whether an association may regulate a homeowner's landscaping.⁹

Nationally, Delaware sits with the silent, CC&R-governed states, a contrast to drought-exposed jurisdictions such as California, Arizona, Nevada, Colorado, Texas, and Florida, which have enacted statutes limiting HOA authority over water-efficient landscaping.¹¹ What follows sets out the statutory and regulatory framework, what the framework requires of associations, recent legislative and judicial activity, and Delaware's national position.

Section 2: The statutory and regulatory framework

2A. Statutory limits on HOA authority over water-efficient landscaping

Review the Delaware Code, and no provision restricts an association's authority over drought-tolerant or xeriscape landscaping, native or low-water plantings, artificial turf, or water-efficient irrigation. DUCIOA, codified at 25 Del. C. § 81-101 et seq., is the general common interest ownership statute — it governs condominiums, cooperatives, and planned communities created on or after September 30, 2009, and applies in part to communities created earlier.^1,12 Its management provisions address rulemaking, aesthetic and design standards, and enforcement, but none singles out water conservation or landscaping type.^2,5 The predecessor Unit Property Act, at 25 Del. C. ch. 22, governs certain pre-2009 communities and likewise contains no water-conservation landscaping carve-out.¹³

This is a meaningful absence, because Delaware has shown it knows how to override restrictive covenants when it chooses to. The General Assembly voided covenants that prohibit or unreasonably restrict roof-mounted solar systems, at 25 Del. C. § 318, and, in 2023, added § 318A to protect clotheslines.^14,15 No comparable statute exists for water-efficient or drought-tolerant landscaping. Where such a statute would appear, the code stays silent.¹

States that have enacted HOA-restriction statutes make the Delaware gap concrete. California's Civil Code § 4735(a) says a provision of the governing documents or landscaping guidelines "shall be void and unenforceable if it ... Prohibits, or includes conditions that have the effect of prohibiting, the use of low water-using plants as a group or as a replacement of existing turf," and § 4735(c) bars fining an owner for reducing watering during a Governor-declared drought emergency.¹¹ Florida's Fla. Stat. § 373.185 protects Florida-friendly landscaping, and Texas's Tex. Prop. Code § 202.007 protects drought-resistant landscaping and water-conserving turf.¹¹ Delaware has adopted nothing similar. A firm shouldn't assume any such protection applies in Delaware.

2B. Related water law, drought response, rainwater and graywater

Delaware manages water resources through DNREC. Major withdrawals — more than 50,000 gallons per day from surface water or groundwater — require a Water Allocation Permit under 7 Del. C. § 6003 and the allocation regulations.⁹ This framework is water-supply law. It governs who may withdraw water, and it neither constrains nor empowers an association's authority over a homeowner's landscaping — it's presented here only as background.

Delaware's drought-response mechanism is likewise supply-side. Drought watches, warnings, and emergencies get declared by the Governor on the guidance of the Water Supply Coordinating Council, or WSCC; a watch or warning triggers voluntary conservation, while a declared emergency can impose mandatory restrictions on water use.⁴ Governor Matt Meyer declared a statewide drought watch on June 3, 2026, on WSCC guidance. DNREC Secretary Greg Patterson said "A drought watch calls for voluntary actions to reduce personal use of our water resources ... we urge Delawareans to take it very seriously," and the WSCC guidelines ask residents to "Limit watering of lawns and outdoor plants" and "Minimize watering with drinkable (potable) water."¹⁶ The state's last full drought emergency came in 2002, when Governor Ruth Ann Minner declared an emergency by executive order on August 2, 2002 — the "drought of record" — barring lawn watering, car washing, and pool filling north of the Chesapeake and Delaware Canal.¹⁷ These measures direct how water may be used. No Delaware drought declaration reaches private HOA enforcement or suspends an association's power to enforce a green-lawn covenant.⁴

Delaware has no statute addressing rainwater harvesting or graywater reuse as against associations.¹ Rainwater harvesting is lawful and gets encouraged as a stormwater best-management practice, with design standards in 7 DE Admin. Code 5101.³ These are environmental and plumbing standards, not HOA-authority provisions.

2C. Where water-conservation rules actually live in Delaware

For a Delaware community, any water-related landscaping rule lives in the recorded declaration and the association's architectural-control provisions. DUCIOA authorizes an association to adopt rules establishing and enforcing construction and design criteria and aesthetic standards where the declaration reserves that right under § 81-302(a)(16), and it requires that all rules be reasonable.^2,5 Whether a given DUCIOA provision governs a particular community turns on the community's creation date and whether the declaration varies the default, since the act applies in full to communities created on or after September 30, 2009, and only in specified part to earlier communities.^12,13

Any practical, owner-facing water-use rule is far more likely to come from a local water utility than from state law. Artesian Water Company — which describes itself as "the oldest and largest regulated water utility on the Delmarva Peninsula" and has served Delaware since 1905 — supplies water to over a third of Delaware residents; Tidewater Utilities is the largest private supplier south of the Chesapeake and Delaware Canal; and the City of Wilmington's municipal utility serves the Wilmington area.^6,7,8 The Delaware Public Service Commission rate- and service-regulates these utilities.¹⁰ Their conservation measures operate independently of the HOA framework. The operational takeaway: a manager searching for "Delaware HOA water conservation law" will find the rulebook in the declaration and the local water utility's rules — not in any HOA-specific water statute.¹

Section 3: What the framework requires of HOAs

A. Landscaping approval and architectural review

An association may require architectural approval for landscaping changes only if the declaration reserves that authority. DUCIOA lets the association adopt and enforce construction, design, and aesthetic standards under § 81-302(a)(16) and § 81-320, and requires adopting enforcement and approval procedures, including a reasonable time to act on an application.^2,5 The substantive landscaping standard itself — whether xeriscape or artificial turf gets permitted — comes from the declaration.¹

B. Drought response and watering restrictions

Delaware imposes no statutory drought limit on HOA enforcement; state drought watches and warnings call for voluntary conservation and don't suspend association enforcement.⁴ Any mandatory outdoor-watering restriction that reaches a homeowner is a utility or local measure, not a state HOA mandate.^6,7

C. Rule adoption and disclosure

DUCIOA requires that association rules be reasonable and that the executive board maintain a current, complete statement of all rules; rulemaking must stay consistent with the recorded bylaws and declaration.^2,5 Any water- or landscaping-specific standard must go through this process and get recorded or disclosed accordingly.¹

D. Enforcement limits and conflicts

DUCIOA directs the executive board to use reasonable judgment in deciding whether to enforce a covenant or rule, and it recognizes that a board may decline enforcement where a covenant is, or is likely to be construed as, inconsistent with current law.⁵ A genuine conflict can arise where a declaration requires a green, irrigated lawn while a local water utility imposes a mandatory watering restriction during a dry period. In Delaware, that's a contract-versus-local-rule tension resolved under general law and the utility's authority, not under any water-conservation statute, because none exists.^1,6

Section 4: Recent legislative and judicial activity

A. Recent bills

No qualifying bill turned up. A review of the Delaware 152nd (2023-2024) and 153rd (2025-2026) General Assembly records found no bill that would create or affect an HOA's authority over water-efficient, drought-tolerant, or xeriscape landscaping, native plants, artificial turf, rainwater harvesting, graywater, or drought-emergency lawn enforcement.¹⁰ Delaware's only covenant-override statutes remain energy-related: § 318 for solar, and § 318A for clotheslines, added by SB 130 in 2023.^14,15 Neither addresses water or landscaping conservation.

B. Recent Delaware Supreme Court rulings

No qualifying ruling on HOA landscaping or water-related use restrictions turned up in the past 36 months. The Delaware Supreme Court's one on-point HOA covenant-enforcement decision in the window concerned a vehicle-parking covenant, not landscaping or water use.

Delaware splits trial jurisdiction between the Superior Court, for law, and the Court of Chancery, for equity, and many association disputes proceed in the Court of Chancery. Delaware has no intermediate appellate court — civil appeals go directly to the Delaware Supreme Court.¹⁹

C. Active legislative debates

No active proposal to create a Delaware HOA water-conservation landscaping protection has surfaced.¹⁰

Section 5: National positioning and related coverage

On water conservation specifically, states cluster differently than they do on the general governing statute. One group has enacted statutes limiting HOA authority over water-efficient landscaping, concentrated in drought-exposed jurisdictions such as California, Arizona, Nevada, Colorado, Texas, Florida, and Utah. A second group has partial or emerging provisions. A third group is silent and CC&R-governed, and it takes in most Mid-Atlantic states, Delaware included.¹¹ The practical point for a firm operating across state lines is direct: don't assume the California or Nevada xeriscape-protection rules you know apply in Delaware, where the declaration and local utility rules control. Delaware shows no legislative momentum toward such a statute — no bill on the subject has appeared in the current or prior General Assembly.¹⁰

HOA Weekly's Delaware water-conservation coverage updates quarterly as the General Assembly and the Delaware Supreme Court act. For Delaware communities, the practically controlling water rules are the recorded declaration and the local water utility. Federal frameworks apply to Delaware associations regardless of state law — the Fair Housing Act, the Americans with Disabilities Act, and the Fair Debt Collection Practices Act among them.
