Water conservation and landscaping

Find state water-conservation and landscaping rules, including rainwater, graywater, drainage, HOA limits, and local approvals.

What this topic covers

Water and landscaping projects sit between municipal rules (water supply, drainage, mosquito
control) and association rules (aesthetics, placement, and maintenance). State statutes sometimes
limit what an HOA may prohibit, but the details are intensely local.

Which authority usually controls

  1. State statute — where it exists, protection for rainwater harvesting, drought-tolerant
    landscaping, or clotheslines (for example, Texas Property Code provisions on rainwater
    harvesting and restrictive covenants).
  2. Municipal rules — water-supply rules, drainage and overflow requirements, and mosquito
    control.
  3. Governing documents — HOA and condominium aesthetic and landscaping rules, within the
    limits of state law.

Common questions

  • Can my HOA ban rain barrels or a clothesline?
  • Can an HOA require turf or reject drought-tolerant landscaping?
  • What permits or registrations do rainwater or graywater systems need?
  • Who is responsible for drainage and overflow?

What is still controlled locally or privately

A statute that limits HOA prohibitions does not waive municipal water, drainage, or safety rules,
and does not stop an association from applying reasonable, written landscaping standards that the
law allows. Overflow, mosquito, and structural-safety issues are real regulatory concerns, not
aesthetic preferences.

Common mistakes

  • Assuming a statewide right to harvest rainwater means no municipal or safety rules.
  • Treating an HOA aesthetic rule as automatically void because a statute exists.
  • Installing a rain barrel or graywater system without checking drainage and permit rules.

What rules apply to a residential graywater system?

Graywater rules depend on the water source, intended use, system design, and location. Arizona limits specified municipal restrictions; Santa Cruz County describes a narrow laundry-irrigation permit exemption. Colorado authorizes qualifying use from 2026 but allows local opt-outs and generally limits indoor systems to new construction unless local law allows otherwise. HOA requirements need a separate analysis.

Can an HOA prohibit clotheslines?

Not necessarily. California, Colorado, Florida, Hawaii, Maine, Maryland, Michigan, and Vermont protect clotheslines in specified circumstances, although the eligible property, device, and placement rules differ. Hawaii expressly protects clotheslines on an owned single-family dwelling or townhouse. Utah has a separate land-use approval mechanism. Check the law for your property before accepting an HOA ban as enforceable.

Can an HOA restrict compost bins and compost piles?

State law can limit composting restrictions. Maryland protects qualifying HOA lot owners’ home composting and private collection; Texas protects vegetation composting with device and location limits. California protects qualifying backyard agriculture and supporting compost. Condominium and shared-area rights can differ.

Can my HOA ban native or drought-tolerant landscaping?

Colorado, Texas, Florida, and Nevada limit HOA restrictions on specified water-saving landscapes. The protected plants, property types, application steps, and design conditions differ. Compare the proposed rule with the statute for your property before accepting a ban.

Who is responsible for rainwater drainage and mosquito control around my home?

Drainage and mosquito control around a home are mostly the property owner's job: overflow from rain barrels and gutters must be directed away from buildings, and standing water that breeds mosquitoes is something health agencies expect you to eliminate. The exact rules come from local drainage codes and health departments, with a few state laws like Colorado's residential rainwater collection statute.

How do I read HOA and condo governing documents before an energy upgrade?

Read three documents in order — the declaration (CC&Rs), the bylaws, and the board's rules — and remember that state statutes can override all of them. Request current copies in writing, then check architectural review, exclusive-use areas, common elements, maintenance, and insurance provisions.

Colorado rainwater collection rules for homeowners

Colorado homeowners may collect rooftop precipitation in up to two rain barrels with a combined capacity of 110 gallons or less, used for outdoor purposes on the property where collected — no permit is required. The water cannot be used for drinking or indoor household purposes, and common interest community associations may not prohibit such barrels, though placement and aesthetic rules may still apply.

Colorado HOA rules for xeriscaping and water-saving landscapes

Colorado law bars HOAs and other common interest communities from prohibiting xeriscape, nonvegetative turf grass, or drought-tolerant landscapes as ground cover — for attached single-family homes under C.R.S. 38-33.3-106.5(1)(i)(I)(A) and for detached single-family homes under the broader (1)(i.5) — while still allowing design guidelines, review, and reasonable limits. Rain barrels are protected separately.

Texas HOA rules for native and drought-tolerant landscaping

Texas Property Code § 202.007 protects drought-resistant landscaping and water-conserving natural turf from HOA prohibitions. An HOA may require a landscape plan and regulate specified design details, but it cannot unreasonably deny a covered proposal. A plant’s being native is not enough by itself: the design must meet the statutory category. Local water, drainage, and safety requirements still apply.

Can a Texas HOA restrict my rain barrel or rainwater system?

Texas protects rain barrels and rainwater-harvesting systems, subject to specified property, street-location, appearance, and visible-equipment rules. A narrow statutory exception also excludes certain large developments. Use the actual site and the association’s cited exception rather than a blanket yes or no.
